 # Changelog
 
+## 2026-03-09 - 4.2.0 - feat(smartpdf)
+replace internal Express server with @push.rocks/smartserve, add PDF→WebP rendering, improve start/stop handling and bump dependencies
+
+- Replace internal Express HTTP implementation with @push.rocks/smartserve and update README wording to reflect HTTP server usage
+- Add PDF→WebP rendering: use pdf.js in-page rendering, capture canvases via Puppeteer to produce WebP buffers; added robust wait/timeout and error handling
+- Add start/stop guards: _isRunning flag, reset readiness Deferred on start, and throw if start called while running
+- Remove direct http/express exports from plugins and stop exporting express; export smartserve from plugins
+- Improve JPEG conversion to produce progressive JPEGs via SmartJimp (sharp mode)
+- Bump dependencies/devDependencies: @push.rocks/smartfs to ^1.5.0, add @push.rocks/smartserve ^2.0.1; devDeps @git.zone/tsbuild ^4.3.0, @git.zone/tstest ^3.3.0, @types/node ^25.3.5
+
+## 2026-03-01 - 4.1.3 - fix(tests)
+use example.com in image conversion test and relax JPEG size assertion
+
+- Replaced https://www.wikipedia.org with https://example.com in test/test.ts for the third PDF generation test
+- Removed the strict expectation that JPEG size must be smaller than PNG; now only asserts that WebP is smaller than PNG
+- Updated test comment to note that JPEG may not be smaller for simple graphics pages
+
+## 2026-03-01 - 4.1.2 - fix(smartfs)
+replace smartfile with smartfs, update file reading to use SmartFs, remove GraphicsMagick/Ghostscript dependency checks, bump dev and runtime dependencies, update tests and docs, and adjust npmextra configuration
+
+- Replace usage/export of @push.rocks/smartfile with @push.rocks/smartfs and update readFileToPdfObject to use SmartFs + SmartFsProviderNode

 ## 📦 Installation
 
 ```bash
-# Using npm
-npm install @push.rocks/smartpdf --save
-
-# Using yarn
-yarn add @push.rocks/smartpdf
-
-# Using pnpm (recommended)
 pnpm add @push.rocks/smartpdf
 ```
 
+> **Prerequisites:** SmartPDF uses headless Chromium via Puppeteer under the hood. On most systems this is handled automatically. If you run into browser-launch issues (CI, Docker, etc.), make sure the required system libraries are installed — see the [Puppeteer troubleshooting guide](https://pptr.dev/troubleshooting).
+
 ## 🎯 Quick Start
 
 ```typescript
 import { SmartPdf } from '@push.rocks/smartpdf';
+import * as fs from 'fs';
 
-// Create and start SmartPdf
+// 1. Create and start
 const smartPdf = await SmartPdf.create();
 await smartPdf.start();
 
-// Generate a PDF from HTML
+// 2. Generate a PDF from HTML
 const pdf = await smartPdf.getA4PdfResultForHtmlString(`
   <h1>Hello, PDF World! 🌍</h1>
-  <p>This is my first SmartPDF document.</p>
+  <p>Generated with SmartPDF.</p>
 `);
 
-// Save it
+// 3. Write to disk
-await fs.writeFile('my-first-pdf.pdf', pdf.buffer);
+fs.writeFileSync('my-first.pdf', pdf.buffer);
 
-// Don't forget to clean up!
+// 4. Clean up
 await smartPdf.stop();
 ```
 
-## 📚 Core Concepts
+Every method returns an `IPdf` object:
 
-### 🏗️ Instance Management
+```typescript
+interface IPdf {
+  id: string | null;        // Unique identifier
+  name: string;             // Filename
+  buffer: Buffer;           // Raw PDF bytes
+  metadata?: {
+    textExtraction?: string; // Extracted text (when available)
+  };
+}
+```
 
-SmartPDF uses a client-server architecture for maximum performance. Always remember:
+## 📚 How It Works
 
-1. **Create** an instance
+SmartPDF spins up a lightweight HTTP server (via `@push.rocks/smartserve`) bound to `localhost` and a headless Chromium browser. When you call a generation method:
-2. **Start** the server
+
-3. **Do your PDF magic**
+1. Your HTML is registered internally and served at `http://localhost:{port}/{id}`
-4. **Stop** the server
+2. Puppeteer navigates to that URL, waits for the page to fully render, and captures a PDF
+3. A header-based security check ensures only the correct content is captured
+4. The server and browser are torn down when you call `stop()`
+
+This architecture means you get **pixel-perfect CSS rendering**, **web font support**, and **full JavaScript execution** — the same rendering engine that powers Chrome.
+
+## 🏗️ Instance Management
 
 ```typescript
 const smartPdf = await SmartPdf.create();
 await smartPdf.start();
-// ... your PDF operations ...
+
+// ... your operations ...
+
 await smartPdf.stop();
 ```
 
+For production use, wrap in try/finally:
+
+```typescript
+const smartPdf = await SmartPdf.create();
+try {
+  await smartPdf.start();
+  // ... generate PDFs ...
+} finally {
+  await smartPdf.stop();
+}
+```
+
 ### 🔌 Smart Port Allocation
 
-Run multiple instances without port conflicts:
+Run multiple instances without conflicts:
 
 ```typescript
-// Each instance automatically finds a free port
+// Each instance auto-selects a free port (default range: 20000–30000)
-const instance1 = await SmartPdf.create(); // Port: 20000
+const instance1 = new SmartPdf();
-const instance2 = await SmartPdf.create(); // Port: 20001
+const instance2 = new SmartPdf();
-const instance3 = await SmartPdf.create(); // Port: 20002
+await instance1.start(); // e.g. port 20000
+await instance2.start(); // e.g. port 20001
 
-// Or specify custom settings
+console.log(instance1.serverPort); // 20000
-const customInstance = await SmartPdf.create({
+console.log(instance2.serverPort); // 20001
-  port: 3000,              // Use specific port
+
-  portRangeStart: 4000,    // Or define a range
+// Custom range
-  portRangeEnd: 5000
+const custom = new SmartPdf({ portRangeStart: 4000, portRangeEnd: 5000 });
-});
+
+// Or pin a specific port
+const pinned = new SmartPdf({ port: 3000 });
 ```
 
-## 🎨 PDF Generation
+If a specific port is already in use, `start()` throws an error immediately instead of silently failing.
 
-### 📝 From HTML String
+### 🌐 Bring Your Own Browser
 
-Create beautiful PDFs from HTML with full CSS support:
+Pass an existing Puppeteer `Browser` instance — SmartPDF won't close it when you call `stop()`:
-
-```typescript
-const smartPdf = await SmartPdf.create();
-await smartPdf.start();
-
-const pdf = await smartPdf.getA4PdfResultForHtmlString(`
-  <!DOCTYPE html>
-  <html>
-    <head>
-      <style>
-        @import url('https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;700&display=swap');
-        
-        body {
-          font-family: 'Roboto', sans-serif;
-          margin: 40px;
-          color: #333;
-        }
-        
-        .header {
-          background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
-          color: white;
-          padding: 30px;
-          border-radius: 10px;
-          text-align: center;
-        }
-        
-        .content {
-          margin-top: 30px;
-          line-height: 1.6;
-        }
-        
-        .highlight {
-          background-color: #ffd93d;
-          padding: 2px 6px;
-          border-radius: 3px;
-        }
-      </style>
-    </head>
-    <body>
-      <div class="header">
-        <h1>Invoice #2024-001</h1>
-        <p>Generated on ${new Date().toLocaleDateString()}</p>
-      </div>
-      <div class="content">
-        <h2>Bill To:</h2>
-        <p>Acme Corporation</p>
-        <p>Total: <span class="highlight">$1,234.56</span></p>
-      </div>
-    </body>
-  </html>
-`);
-
-await fs.writeFile('invoice.pdf', pdf.buffer);
-await smartPdf.stop();
-```
-
-### 🌐 From Website
-
-Capture any website as a PDF with two powerful methods:
-
-#### Standard A4 Format
-Perfect for articles and documents:
-
-```typescript
-const pdf = await smartPdf.getPdfResultForWebsite('https://example.com');
-```
-
-#### Full Page Capture
-Capture the entire scrollable area:
-
-```typescript
-const fullPagePdf = await smartPdf.getFullWebsiteAsSinglePdf('https://example.com');
-```
-
-### 🔀 Merge Multiple PDFs
-
-Combine PDFs like a pro:
-
-```typescript
-// Load your PDFs
-const invoice = await smartPdf.readFileToPdfObject('./invoice.pdf');
-const terms = await smartPdf.readFileToPdfObject('./terms.pdf');
-const contract = await smartPdf.getA4PdfResultForHtmlString('<h1>Contract</h1>...');
-
-// Merge them in order
-const mergedPdf = await smartPdf.mergePdfs([
-  contract.buffer,
-  invoice.buffer,
-  terms.buffer
-]);
-
-await fs.writeFile('complete-document.pdf', mergedPdf);
-```
-
-## 🖼️ Image Generation
-
-### 🎨 Convert PDF to Images
-
-SmartPDF supports three image formats, each with its own strengths:
-
-#### PNG - Crystal Clear Quality
-
-```typescript
-const pngImages = await smartPdf.convertPDFToPngBytes(pdf.buffer, {
-  scale: SmartPdf.SCALE_HIGH  // 216 DPI - perfect for most uses
-});
-
-// Save each page
-pngImages.forEach((png, index) => {
-  fs.writeFileSync(`page-${index + 1}.png`, png);
-});
-```
-
-#### WebP - Modern & Efficient
-
-```typescript
-const webpImages = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
-  quality: 90,  // 0-100 quality scale
-  scale: 2.0    // 144 DPI - great for web
-});
-```
-
-#### JPEG - Progressive Loading
-
-```typescript
-const jpegImages = await smartPdf.convertPDFToJpegBytes(pdf.buffer, {
-  quality: 85,              // Balance between size and quality
-  scale: SmartPdf.SCALE_SCREEN,  // 144 DPI
-  maxWidth: 1920            // Constrain dimensions
-});
-```
-
-### 📏 DPI & Scale Guide
-
-SmartPDF makes it easy to get the right resolution:
-
-```typescript
-// Built-in scale constants
-SmartPdf.SCALE_SCREEN  // 2.0 = ~144 DPI (web display)
-SmartPdf.SCALE_HIGH    // 3.0 = ~216 DPI (high quality, default)
-SmartPdf.SCALE_PRINT   // 6.0 = ~432 DPI (print quality)
-
-// Or calculate your own
-const scale = SmartPdf.getScaleForDPI(300); // Get scale for 300 DPI
-```
-
-### 🖼️ Thumbnail Generation
-
-Create perfect thumbnails for document previews:
-
-```typescript
-const thumbnails = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
-  scale: 0.5,      // Small but readable
-  quality: 70,     // Lower quality for tiny files
-  maxWidth: 200,   // Constrain to thumbnail size
-  maxHeight: 200
-});
-```
-
-## 📊 Format Comparison
-
-Choose the right format for your needs:
-
-| Format | File Size | Best For | Special Features |
-|--------|-----------|----------|------------------|
-| **PNG** | Largest | Screenshots, diagrams, text | Lossless, transparency |
-| **JPEG** | 30-50% of PNG | Photos, complex images | Progressive loading |
-| **WebP** | 25-40% of PNG | Modern web apps | Best compression |
-
-## 🛡️ Best Practices
-
-### 1. Always Use Try-Finally
-
-```typescript
-let smartPdf: SmartPdf;
-
-try {
-  smartPdf = await SmartPdf.create();
-  await smartPdf.start();
-  
-  // Your PDF operations
-  
-} finally {
-  if (smartPdf) {
-    await smartPdf.stop(); // Always cleanup!
-  }
-}
-```
-
-### 2. Optimize HTML for PDFs
-
-```typescript
-const optimizedHtml = `
-  <style>
-    /* Use print-friendly styles */
-    @media print {
-      .no-print { display: none; }
-    }
-    
-    /* Avoid page breaks in wrong places */
-    h1, h2, h3 { page-break-after: avoid; }
-    table { page-break-inside: avoid; }
-  </style>
-  ${yourContent}
-`;
-```
-
-### 3. Handle Large Documents
-
-For documents with many pages:
-
-```typescript
-// Process in batches
-const pages = await smartPdf.convertPDFToPngBytes(largePdf.buffer);
-
-for (let i = 0; i < pages.length; i += 10) {
-  const batch = pages.slice(i, i + 10);
-  await processBatch(batch);
-}
-```
-
-## 🎯 Advanced Usage
-
-### 🌐 Custom Browser Instance
-
-Bring your own Puppeteer instance:
 
 ```typescript
 import puppeteer from 'puppeteer';
 
 const browser = await puppeteer.launch({
   headless: 'new',
-  args: ['--no-sandbox', '--disable-dev-shm-usage']
+  args: ['--no-sandbox'],
 });
 
 const smartPdf = await SmartPdf.create();
-await smartPdf.start(browser);
+await smartPdf.start(browser); // uses your browser
 
-// SmartPdf won't close your browser
+await smartPdf.stop();      // server stops, browser stays open
-await smartPdf.stop();
+await browser.close();       // you manage browser lifecycle
-await browser.close(); // You manage it
 ```
 
-### ⚡ Parallel Processing
+## 🎨 PDF Generation
 
-Process multiple PDFs concurrently:
+### 📝 HTML → A4 PDF
+
+Renders at a 794×1122 viewport (A4 at 96 DPI) with full CSS support:
 
 ```typescript
-const urls = ['https://example1.com', 'https://example2.com', 'https://example3.com'];
+const pdf = await smartPdf.getA4PdfResultForHtmlString(`
+  <style>
+    body { font-family: 'Helvetica', sans-serif; margin: 40px; }
+    .header {
+      background: linear-gradient(135deg, #667eea, #764ba2);
+      color: white; padding: 30px; border-radius: 10px; text-align: center;
+    }
+    table { width: 100%; border-collapse: collapse; margin-top: 20px; }
+    th, td { border: 1px solid #ddd; padding: 8px; text-align: left; }
+    th { background: #f5f5f5; }
+  </style>
 
-const pdfs = await Promise.all(
+  <div class="header">
-  urls.map(url => smartPdf.getFullWebsiteAsSinglePdf(url))
+    <h1>Invoice #2024-001</h1>
-);
+  </div>
 
-// Or with multiple instances for maximum performance
+  <table>
+    <tr><th>Item</th><th>Qty</th><th>Price</th></tr>
+    <tr><td>Widget Pro</td><td>5</td><td>$49.99</td></tr>
+    <tr><td>Gizmo Ultra</td><td>2</td><td>$129.99</td></tr>
+  </table>
+`);
+
+fs.writeFileSync('invoice.pdf', pdf.buffer);
+```
+
+### 🌐 Website → PDF
+
+Two methods depending on your needs:
+
+```typescript
+// Standard capture — uses the document's own dimensions
+const pdf = await smartPdf.getPdfResultForWebsite('https://example.com');
+
+// Full-page capture — scrolls to bottom, captures everything as a single page
+const fullPdf = await smartPdf.getFullWebsiteAsSinglePdf('https://example.com');
+```
+
+`getPdfResultForWebsite` uses a 1980×1200 viewport and respects the page's own width/height. `getFullWebsiteAsSinglePdf` uses a 1920px-wide viewport and measures the full scroll height, producing a single tall page.
+
+### 🔀 Merge Multiple PDFs
+
+Combine any number of PDF buffers into one document using `pdf-lib`:
+
+```typescript
+const invoice = await smartPdf.readFileToPdfObject('./invoice.pdf');
+const terms = await smartPdf.readFileToPdfObject('./terms.pdf');
+const appendix = await smartPdf.getA4PdfResultForHtmlString('<h1>Appendix</h1>...');
+
+const merged = await smartPdf.mergePdfs([
+  invoice.buffer,
+  terms.buffer,
+  appendix.buffer,
+]);
+
+fs.writeFileSync('complete-package.pdf', merged);
+```
+
+### 📑 Read a PDF from Disk
+
+```typescript
+const pdfObject = await smartPdf.readFileToPdfObject('./document.pdf');
+console.log(pdfObject.name);   // "document.pdf"
+console.log(pdfObject.buffer); // <Buffer ...>
+```
+
+### 📖 Extract Text
+
+Pull raw text from any PDF buffer:
+
+```typescript
+const text = await smartPdf.extractTextFromPdfBuffer(pdf.buffer);
+console.log(text);
+```
+
+> Uses [pdf2json](https://github.com/modesty/pdf2json) under the hood. Works best with text-based PDFs; scanned documents may return limited results.
+
+## 🖼️ PDF → Image Conversion
+
+Convert PDF pages to raster images using Puppeteer + PDF.js. Each page becomes a separate image buffer.
+
+### PNG — Lossless Quality
+
+```typescript
+const pngPages = await smartPdf.convertPDFToPngBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH, // 3.0 = ~216 DPI (default)
+});
+
+pngPages.forEach((png, i) => {
+  fs.writeFileSync(`page-${i + 1}.png`, Buffer.from(png));
+});
+```
+
+### WebP — Modern & Efficient
+
+25–60% smaller than PNG at similar visual quality:
+
+```typescript
+const webpPages = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
+  scale: 2.0,     // ~144 DPI
+  quality: 90,    // 0–100 (default: 85)
+});
+```
+
+### JPEG — Progressive Loading
+
+Generates true progressive JPEGs (multi-pass rendering) via sharp:
+
+```typescript
+const jpegPages = await smartPdf.convertPDFToJpegBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH,
+  quality: 85,       // 0–100 (default: 85)
+  maxWidth: 1920,    // optional dimension constraints
+  maxHeight: 1080,
+});
+```
+
+### 📏 DPI & Scale Reference
+
+All image methods accept a `scale` parameter. PDF.js renders at 72 DPI by default, so `scale` is a multiplier:
+
+| Constant | Value | DPI | Use Case |
+|----------|-------|-----|----------|
+| `SmartPdf.SCALE_SCREEN` | 2.0 | ~144 | Web display, thumbnails |
+| `SmartPdf.SCALE_HIGH` | 3.0 | ~216 | General purpose (default) |
+| `SmartPdf.SCALE_PRINT` | 6.0 | ~432 | Print-quality output |
+
+Or calculate a custom scale:
+
+```typescript
+const scale = SmartPdf.getScaleForDPI(300); // → 4.167
+```
+
+### 🖼️ Dimension Constraints
+
+All image methods support `maxWidth` and `maxHeight` to cap output size while preserving aspect ratio:
+
+```typescript
+// High-res render, but capped at 800×1000 px
+const constrained = await smartPdf.convertPDFToWebpBytes(pdf.buffer, {
+  scale: SmartPdf.SCALE_HIGH,
+  quality: 90,
+  maxWidth: 800,
+  maxHeight: 1000,
+});
+```
+
+### 📊 Format Comparison
+
+| Format | Typical Size vs PNG | Lossy? | Transparency | Progressive | Best For |
+|--------|-------------------|--------|--------------|-------------|----------|
+| **PNG** | baseline | No | ✅ | — | Screenshots, diagrams, text-heavy docs |
+| **WebP** | 40–75% | Yes | ✅ | — | Modern web apps, thumbnails |
+| **JPEG** | 50–70% | Yes | ❌ | ✅ | Photos, complex graphics, email |
+
+## ⚡ Parallel Processing
+
+Process multiple URLs concurrently with separate instances:
+
+```typescript
+const urls = [
+  'https://example.com/page1',
+  'https://example.com/page2',
+  'https://example.com/page3',
+];
+
+// Spin up parallel instances
 const instances = await Promise.all(
-  Array(3).fill(null).map(() => SmartPdf.create())
+  urls.map(() => SmartPdf.create())
 );
-
 await Promise.all(instances.map(i => i.start()));
 
-// Process in parallel across instances
+// Generate in parallel
-const results = await Promise.all(
+const pdfs = await Promise.all(
-  urls.map((url, i) => instances[i % instances.length].getFullWebsiteAsSinglePdf(url))
+  urls.map((url, i) => instances[i].getFullWebsiteAsSinglePdf(url))
 );
 
-// Cleanup all instances
+// Merge all results
+const merged = await instances[0].mergePdfs(pdfs.map(p => p.buffer));
+fs.writeFileSync('all-pages.pdf', merged);
+
+// Clean up
 await Promise.all(instances.map(i => i.stop()));
 ```
