Free PDF Tools Tools
6 free browser-based PDF tools — PDF to image, PDF merger, PDF splitter, Word to PDF, Markdown to PDF and more. No uploads to servers. Your files never leave your device.
Whether you need to convert a PDF to high-resolution images for a presentation, extract individual pages as JPGs, or prepare PDF content for sharing on social media — LazyTools' free PDF tool handles it entirely in your browser. Your documents are never uploaded to any external server, making it safe for confidential contracts, financial statements and identity documents.
The free PDF to Image Converter converts every page of any PDF to JPG, PNG or WebP at any DPI — from 72 DPI for screen use to 300 DPI for print quality. Download pages individually or as a ZIP archive. No file size limits, no watermarks, no account required.

Free Online PDF Tools: The Complete Guide
PDF manipulation typically requires either paid desktop software like Adobe Acrobat, or online tools that upload your documents to remote servers — creating significant privacy risks for sensitive files. LazyTools processes PDFs client-side using WebAssembly-compiled rendering libraries: your documents never leave your device.
Free PDF to Image Converter — PDF to JPG, PNG and WebP
The free PDF to Image Converter renders each page of a PDF as a raster image at configurable resolution. Choose 72 DPI for screen embedding (a standard A4 page produces approximately 595x842 pixels), 150 DPI for general-purpose use including on-screen zoom (approximately 1240x1754 pixels), 300 DPI for professional print quality (approximately 2480x3508 pixels), or custom DPI up to 600 for large-format printing. Output formats: JPG (compressed, ideal for photos and screenshots), PNG (lossless, ideal for text and diagrams requiring transparency) and WebP (modern format with excellent compression for web use). Multi-page PDFs produce multiple image files downloadable individually or as a ZIP archive.
Common use cases for PDF to image conversion: extracting a specific page from a technical manual to share on a messaging platform, converting a one-page PDF certificate or flyer to an image for embedding in a website or email, preparing PDF slides as images for upload to LinkedIn or Instagram carousels, archiving signed documents as high-resolution images for visual reference, and extracting diagrams or charts from PDF reports for use in presentations.
Why Client-Side PDF Processing Matters for Privacy
PDFs often contain highly sensitive information: legal contracts, financial statements, medical records, tax returns, employment documents, passport scans and confidential business plans. Uploading these to online PDF tools — even those with privacy policies — creates legal and security risks. When PDF processing runs in your browser using WebAssembly, the document data exists only in device memory during processing and is never transmitted over the network. This is the only genuinely private approach to PDF manipulation available without installing desktop software.
Technical Architecture: How Client-Side PDF Processing Works
The PDF to Image Converter uses PDF.js — Mozilla's open-source JavaScript PDF rendering engine, also used in Firefox's built-in PDF viewer — compiled to run in the browser. PDF.js implements the full PDF rendering pipeline: parsing document structure, resolving font resources, rasterising vector graphics and text, and compositing the final page image. Output is captured from an HTML5 Canvas element and encoded as the selected image format using the browser's native Canvas.toBlob() API. The pipeline executes in a Web Worker to avoid blocking the browser's main thread, keeping the page responsive during conversion of large multi-page PDFs.
PDF to Image DPI Guide — Choosing the Right Resolution
72 DPI is the screen resolution standard — suitable for embedding in web pages or displaying on screen but too low for print. 150 DPI is good for general-purpose use including on-screen viewing at zoom and light print use. 300 DPI is the professional print standard — suitable for high-quality printing and archiving, producing file sizes of approximately 1-5MB per page depending on content. For large-format print (posters, banners), 600 DPI may be needed, producing very large individual image files. The tool's DPI selector makes it straightforward to choose the right output resolution for each use case without needing to understand the underlying pixel mathematics.
Supported PDF Types
The converter handles both text-based PDFs (where text is stored as vector instructions in the PDF structure — the most common type produced by word processors, design tools and digital printers) and image-based PDFs (scanned documents where each page is already a raster image). For scanned PDFs, the rasterisation step re-renders the existing page image at the specified DPI. Very large PDFs (hundreds of pages) are processed page-by-page to manage browser memory efficiently, with a progress indicator showing conversion status.
