PDF to PNG
Render each page of a PDF into a separate PNG image at a DPI you choose. 150 DPI suits screen use and 300 DPI matches print. PNG is lossless, so screenshots, diagrams, and small text come out exactly as rendered. Files are larger than JPG, sometimes much larger on photographic pages. Runs on your own Vistalyth Tools instance. Files never reach a third party.

Self-hosted. Your files never leave your network.

Frequently asked questions
- What DPI should I pick?
- 150 for screens, 300 for print, 600 only if you plan to OCR small type afterwards. Higher DPI multiplies render time and file size quickly.
- Can I convert only some pages?
- Yes. Give a page range and only those pages render.
- Anything to watch with PNG output?
- Expect roughly 3-5x the file size of the same page rendered to JPG, which is the price of exact text edges.
- Does this work on password-protected PDFs?
- Not directly. Remove the password with Unlock PDF first, then convert.
