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.

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.

Frequently asked questions

What happens to transparent areas?

They are preserved in the PDF. Most viewers render them over white; a viewer with a dark background will show the background through.

Can I put several PNGs on one page?

Not directly. Build the PDF one image per page, then use N-Up to place 2, 4, 6 or 9 pages per sheet.

Will text in the screenshot be selectable?

No. The page is an image. Use OCR if you need the text.

Does it handle 16-bit or indexed PNGs?

Yes. Any PNG the browser can decode is embedded correctly.

How do I add a page size like A4?

Convert first, then use Resize PDF Pages — the image is scaled to fit and centred.

Are my images uploaded?

No. The PDF is built with pdf-lib in your browser.
