PDF page sizes
| Page size | Points | Inches | Millimetres | Pixels at 300 DPI |
|---|---|---|---|---|
| A4 (ISO) | 595 × 842 pt | 8.27 × 11.69 in | 210 × 297 mm | 2,480 × 3,508 px |
| Letter (US) | 612 × 792 pt | 8.5 × 11 in | 216 × 279 mm | 2,550 × 3,300 px |
PDF measures pages in points, and there are exactly 72 points to an inch — so a page's pixel size depends entirely on the DPI you render it at. A4 is the international standard; Letter is used in the US and Canada.
Frequently asked questions
Are my PNG images uploaded?+
No. Your PNG (and JPG) images are combined into a PDF entirely in your browser — nothing is sent to a server. It's safe for screenshots of private information and works offline once loaded.
How is PNG transparency handled in the PDF?+
PDF pages aren't transparent, so any transparent areas of a PNG are flattened onto a white page. If you need the transparency preserved, keep the original PNG — a PDF isn't the right format for it.
Can I combine several PNGs into one PDF?+
Yes. Add all the images at once and each becomes a page in a single PDF, in the order you add them. You can mix PNG and JPG in the same file.
Does converting reduce PNG quality?+
No. PNGs are lossless and are embedded at their original resolution; the only change is the container. On a fixed page size they're scaled to fit but never re-compressed.
Is it free?+
Yes — no signup, no watermark, no per-file limit. It's ad-supported and runs entirely in your browser.
