Pick the right resolution
- 1× — Screen size. Tiny files, fine for thumbnails and previews.
- 2× — The sweet spot. Crisp on Retina/HiDPI displays, reasonable file size. Use this by default.
- 3× — Print quality. Use when you need to physically print the converted page.
- 4× — Very high resolution for archival or detailed inspection. Large files.
The format trick most people miss
Use WebP for archival. It looks as good as PNG but the file is often half the size. Especially valuable for multi-page documents where the savings stack up.
Common reasons to extract images from PDFs
- Share a single page on social media or in a chat
- Embed a PDF page in a slide deck or document
- Make a PDF scannable on devices that can't open PDFs natively
- OCR a scanned PDF (run images through OCR services)
- Build thumbnails for a document library
FAQ
Why does it take a few seconds per page?
+
Each page is fully rendered using PDF.js (the open-source PDF engine that powers Firefox) at the resolution you chose. Higher resolutions take proportionally longer.
Does it work with password-protected PDFs?
+
No. You'd need to remove the password first using a PDF tool that supports decryption with the correct password.
Is my PDF uploaded?
+
No. The entire conversion happens in your browser. The only network request is to load PDF.js from a CDN — your PDF data never leaves your device.
