Why PNG for PDF pages
Most PDFs are made of text and vector graphics: crisp letters, lines and shapes. When a page becomes an image, PNG keeps every edge exactly as rendered, with no blur or speckles around letters. That makes PNG the right choice for:
- slides and diagrams you’ll put into another presentation or document
- tables and charts you’ll publish on a website or in a report
- pages you’ll edit further, crop or annotate
- documentation screenshots that need readable small text
How to use it
- Pick a resolution and, if you only need some pages, type them in the pages box.
- Choose your PDF or drop it on the box above.
- Download the PNG, or the ZIP with one PNG per page.
Picking pages
Leave the box empty for every page. Otherwise use numbers and ranges: 2 for page 2, 1-4 for the first four pages, 10- for page 10 to the end, or a mix such as 1, 3, 6-8.
Resolution
| Resolution | Use |
|---|---|
| 72 DPI | Small previews and thumbnails |
| 150 DPI | Reading on screens, web pages, slides |
| 300 DPI | Printing and zooming into fine detail |
Pages are capped at around 40 megapixels each, so very large pages, such as posters or engineering drawings at 300 DPI, are scaled down slightly to stay within what a phone browser can handle.
Keeping PNGs small
PNG files of text pages are compact, but pages with photographs can be several megabytes. If size matters:
- use 150 DPI rather than 300 unless you need print quality
- run the results through the PNG compressor, which usually shrinks text pages by more than half with no visible change
- use the PDF to JPG converter for photo-heavy pages
Accuracy
Pages are rendered with pdf.js, Mozilla’s PDF engine used in Firefox, including the fonts embedded in the PDF. What you see in the PNG matches what a PDF viewer shows. Form fields, links and attachments don’t carry over, because a PNG is a flat picture of the page.
Questions
Should I choose PNG or JPG?
Choose PNG for pages that are mostly text, tables, charts or drawings, because PNG never blurs edges. Choose JPG for pages full of photos, where PNG files get very large.
Is the background transparent?
No. Pages are drawn on white paper, as in any PDF viewer, so the PNG has a white background.
How large will the images be?
A text page at 150 DPI is typically 100–400 KB as PNG. At 300 DPI expect roughly four times that. Pages with photos are much larger; use JPG for those.
Can I convert only one page?
Yes. Type its number in the pages box, for example 4, and you get a single PNG instead of a ZIP.
