How PDF to image conversion works on PixlFits
Most "PDF to image" sites upload your PDF to a server, render the pages there, and email or stream the result back. That's slow, exposes your document, and creates compliance risk for sensitive PDFs (contracts, IDs, medical records).
PixlFits uses PDF.js, the same open-source PDF engine Firefox uses, to render your PDF entirely inside your browser. Each page is rasterized to a canvas at your chosen DPI, then encoded as PNG / JPG / WebP. Your PDF never touches a server.
Choosing the right DPI
72 DPI — fine for web preview, smallest files. 150 DPI — the sweet spot for most uses. 216 DPI — sharper for normal printing. 300 DPI — best quality for high-quality print but produces large files and is slower.
Frequently asked questions
Can I convert a password-protected PDF?
Yes. You'll be prompted for the password before the PDF is rendered. The password is used locally only.
What's the page limit?
No hard cap, but very large PDFs (200+ pages at 300 DPI) may slow your browser. Use 150 DPI or process in chunks.
Why is the file size so different?
PNG is lossless and large. JPG is lossy and smaller. WebP is the most modern format, often 25-35% smaller than JPG at the same visual quality.
Is it really free?
Yes. Unlimited, no account, no watermark, no ads.
