PNG when you want crisp, lossless images — text stays sharp, edges stay clean, transparency stays transparent (when it's there). For previews, web use, archival, or anywhere JPG's compression would hurt.
Why PNG over JPG
PNG is lossless. Every pixel of the rendered PDF page makes it into the PNG unchanged. JPG's compression eats fine detail — fine on photos, fuzzy on text and sharp edges.
Use PNG for: pages with text, screenshots, diagrams, logos, anything with sharp lines. Use JPG for: photo-heavy pages where file size matters more than pixel-perfect text.
Run the conversion
Drop your PDF into Flint's PDF to PNG. One PNG per page, downloadable as a zip. DPI choice from 150 (web) to 600 (archival).
No signup, no watermark, no daily cap. The conversion runs server-side so it works the same on a phone as on a laptop.
Output quality
At 300dpi, PNG output is suitable for print or zoom. At 150dpi, it's web-perfect. PNG file sizes scale roughly linearly with DPI — a 300dpi PNG is about 4x the size of a 150dpi one for the same page.
For most uses, default DPI is the right answer. Bump it only if you'll be enlarging or printing at large sizes.
Where PNGs go from here
PNGs slot into anything: PowerPoint, Keynote, Figma, Canva, web pages, documentation. If you want them in a PDF again later (e.g. assembled into a new document), convert image to PDF for the reverse trip.
FAQ
How big are PNGs vs JPGs?
PNG is usually 2–5x larger for photo content, similar or smaller for text-heavy pages. Pick PNG when quality matters more than size.
Does the converter handle multi-page PDFs?
Yes — one PNG per page, all in a zip download.
Can I pick specific pages?
Split the PDF first, then convert. Saves processing time and download size.
Will OCR be applied?
Conversion to PNG doesn't OCR — you're getting the visual page. If you want editable text, convert to Word or Excel instead.
