When PDF to PNG beats JPG
Both formats show a page as an image. The difference is how they store it.
| Page content | Better choice | Why |
|---|---|---|
| Text, tables, forms | PNG | Letters keep sharp edges |
| Charts, diagrams, floor plans | PNG | Thin lines and flat colors stay clean |
| Slides with logos and icons | PNG | No smudges around shapes |
| Full page photos, magazine spreads | JPG | Much smaller files, little visible difference |
A quick rule: if you would zoom in to read it, use PNG. If your PDF is mostly photos, PDF to JPG gives you much lighter files.
Practical uses
- Documentation and wikis: paste a page from a manual into a help article.
- Teaching: put a worksheet or textbook diagram into a slide deck or a learning platform.
- Design feedback: mark up a page from a PDF proof in any image editor.
- Real estate: share one floor plan from a long sales brochure.
- Bug reports for documents: show a developer exactly how a generated invoice or report page looks.
Lossless has a cost. A page of dense print at 300 DPI can be several megabytes as PNG. For a smaller file, try 150 DPI first, or shrink the result with Compress PNG.
Limits to keep in mind
Password protected PDFs are not supported, so remove the password in your PDF reader first. Every page is converted, so for a long file you may want to cut out the pages you need with Split PDF beforehand.
The PNG files have a white background, not a transparent one, even if the PDF page itself has no background color.
A low quality scan stays a low quality scan. Raising the DPI makes a bigger file but cannot recover detail the scanner missed; for scans, 150 DPI is usually enough.
