Why Convert a PDF to Images?
There are many reasons to convert PDF pages to images: sharing individual pages on social media, embedding a document preview on a website, extracting a diagram or chart, or converting a PDF to a format accepted by a tool that doesn't support PDFs. Images are also universally viewable without a PDF reader.
PNG vs. JPG — Which Should You Choose?
PNG is a lossless format — every pixel is stored exactly. It's ideal for documents with text, line art, or screenshots. JPG uses lossy compression, which reduces file size at the cost of slight quality loss around sharp edges (visible as 'JPEG artifacts'). For photos embedded in PDFs, JPG is usually fine. For text-heavy documents, PNG is almost always better.
- Use PNG for documents, forms, presentations, and diagrams
- Use JPG for photo-heavy pages where file size matters more than perfect sharpness
- The quality slider in the tool controls JPG compression level (80–95 is ideal)
How the Conversion Works
PDF pages are rendered using PDF.js, Mozilla's open-source PDF rendering engine (the same one used in Firefox). Each page is drawn onto an HTML canvas at the resolution you specify, then exported as an image. The higher the scale/DPI, the larger and sharper the resulting image — at the cost of more browser memory usage.
Step-by-Step: Convert a PDF to Images
1. Open the PDF to Images tool and drop in your PDF. 2. Choose the output format (PNG or JPG). 3. Select which pages to export — all pages, or a specific range. 4. Click Convert and wait for rendering (larger PDFs take longer). 5. Download individual pages or use 'Download All' to get a ZIP.
Getting the Right Resolution
For web use (thumbnails, previews), a scale of 1x or 1.5x is enough. For printing or high-fidelity archiving, use 2x or higher to get a 200+ DPI equivalent. Very high scales (3x+) can cause browser memory warnings on large documents — try splitting the PDF first if you run into this.
Batch Conversion of Multi-Page PDFs
Each page is exported as a separate image file. The tool processes all pages in sequence and offers a single 'Download All' button that triggers downloads for each page. If your browser blocks multiple simultaneous downloads, allow it in the browser's permissions dialog.
