How Local Rendering Works

Canvas Rendering

PDF.js renders each page to an off-screen HTML5 Canvas element in your browser. This preserves fonts, vectors, and images exactly as they appear in the original PDF.

WASM Acceleration

The rendering engine runs in a WebAssembly sandbox, using your CPU's native instruction set for high-performance page rendering without server latency.

Local Image Generation

Each rendered canvas is converted to your chosen format (JPG or PNG) entirely in browser memory and streamed directly to your download folder.

Convert PDF Pages to Images Without Uploading

Converting PDF pages to images is a common need for designers, developers, and anyone who needs to extract visual content from documents. Whether you're creating thumbnails, extracting diagrams for presentations, or converting scanned documents to image format, our PDF to Image tool provides a professional, high-performance solution.

The primary risk with online PDF-to-image converters is the security of your data. Most tools require you to upload your PDF to a remote server, where it is processed and stored temporarily. This creates a window of vulnerability for data leaks or unauthorized access. DocuStitch eliminates this risk by bringing the rendering logic to you. Using PDF.js and WebAssembly (WASM), our converter runs entirely within your browser's RAM. Your document never leaves your machine, ensuring total data sovereignty.

Our engine supports multiple output formats and quality settings: JPG for optimal compression and smaller file sizes, and PNG for lossless quality with transparency support. You can also adjust the DPI to match your intended use case—72 DPI for screen display, 150 DPI for standard use, or 300 DPI for high-quality printing.

Frequently Asked Questions

Everything you need to know about PDF to Image

Is it safe to convert my sensitive documents here?
Yes. Unlike other tools, DocuStitch renders your PDF locally in your browser. Your files are never uploaded to a server, making it the safest choice for confidential documents.
What's the difference between JPG and PNG?
JPG uses compression to achieve smaller file sizes, making it ideal for web use. PNG is lossless and supports transparency, making it better for graphics and when you need perfect quality.
What DPI should I use?
Use 72 DPI for screen/web use, 150 DPI for standard documents, and 300 DPI for high-quality printing. Higher DPI results in larger image files with more detail.
Does it work on mobile phones?
Yes! Because the rendering logic is in the browser, any modern mobile phone with a browser like Chrome or Safari can run the engine locally.
