What PNG to PDF does
This tool places PNG images into a PDF, one per page, embedding them losslessly with any transparency preserved. PNG is the format of screenshots, diagrams, charts, logos and UI mock-ups, and this is how they become a document that opens the same everywhere and can be printed, attached or merged with other PDFs. The conversion runs in your browser with nothing uploaded.
PNG to PDF vs JPG to PDF
| PNG to PDF | JPG to PDF | |
|---|---|---|
| Embedding | Lossless — pixels identical | Original JPEG bytes — no further loss |
| Transparency | Kept (shown over white in most viewers) | None |
| Best for | Screenshots, text, diagrams, logos, line art | Photographs and scans |
| PDF size | Larger for photographic content | Smaller |
A screenshot of a spreadsheet saved as PNG stays pixel-sharp in the PDF; the same screenshot as JPG would show halos around the text. Choose this tool when the source is a PNG and sharpness matters.
Page layout
- Each page is exactly the image's pixel size, with no margins. A 1920 × 1080 screenshot becomes a landscape page of that size.
- Pages follow the order of selection (alphabetical by filename in most pickers). Reorder PDF Pages fixes the sequence afterwards.
- To get standard paper with margins, run Resize PDF Pages on the result and choose A4 or Letter.
Common uses
- Documentation and bug reports — a sequence of screenshots as a single, ordered document.
- Design reviews — exported mock-ups or wireframes for a client who prefers PDF.
- Charts and figures from analysis tools for a report appendix.
- Certificates and forms exported as PNG that a portal will only accept as PDF.
- Print — logos and graphics prepared for a print shop that wants PDF.
Keeping the file small
PNG compresses flat colour and text extremely well, so screenshot PDFs are small. Photographic PNGs are not — a 12-megapixel photo saved as PNG can be 25 MB. For photos, convert to JPG first (PNG to JPG) and use JPG to PDF, or accept the size. Compress PDF will rasterize pages to JPEG if the result must be smaller, at the cost of transparency and pixel-perfect text.
