How to Convert PDF to PNG (Lossless Page Images)
Updated July 13, 2026
When a PDF page has crisp text, a diagram, or line art you don’t want softened by compression — or when you need a transparent background — PNG is the right image format, and it beats JPG for anything that isn’t a photo.
Steps
- Open PDF to PNG and drop your file.
- Keep the format on PNG and pick a resolution — 150 DPI is a good default.
- Click Convert, then download the images — all pages come back together as a single ZIP.
Why PNG over JPG
PNG is lossless: every pixel is preserved exactly, so text stays crisp and diagrams don’t pick up the blocky artifacts JPG compression introduces at higher compression ratios. It also supports transparency, which matters if you’re extracting a logo or graphic that needs to sit on a different background afterward. The trade-off is file size — PNG produces larger files than JPG for the same image, which matters most on pages with lots of photographic content.
Choosing a resolution
- 72 DPI — small, screen-only images (quick previews, thumbnails)
- 150 DPI — the default; good for on-screen viewing and most everyday use
- 300 DPI — print quality, for anything going into a physical document
Notes
Rendering runs in a background worker, so even a long PDF won’t freeze the tab, and nothing about the document is uploaded. A password-protected PDF needs to be unlocked first. To go the other direction — turning images back into a PDF — use PNG to PDF.
