What is PNG to PDF conversion?
This tool packs one or more PNG images into a single PDF, with each image on its own page. It is ideal for turning scans, receipts, photos or screenshots into one file that is easy to print, archive and share. Everything runs locally in your browser with no upload.
How to use it
- Select or drop in one or more PNG images.
- Check the list and order (pages follow your selection order).
- Click Download PDF to save the merged document.
Handy tips
- Multiple images are paged in selection order; reselect the files to change it.
- Portrait and landscape can be mixed — each page fits its own image.
- If the originals are large and you want a smaller PDF, run them through the image compressor first.
Turning screenshots and charts into a crisp PDF
PNG is at its best with screenshots, charts and anything containing text — images where the lines are sharp and the words have to stay readable. When you build these into a PDF for a report or an archive, each PNG is embedded losslessly, so text and gridlines stay clean even when you zoom in, with none of the fuzzy edges or noise a lossy format would add. Perfect for pages you'll print or project. The cost is file size:
- Because the embedding is lossless, the PDF tends to be large, and it grows fast as you add pages.
- If what you're adding is mostly photographs, PNG's lossless nature just wastes space — use JPG to PDF instead for a much smaller, easier-to-send file.
Same wrapping job: JPEG charges 0.28%, PNG charges 11.0%
This page measures 1.88 MB → 2.08 MB (+11%), an extra 217,359 bytes. The JPEG of that same photograph wrapped as a PDF costs only 945 bytes (0.28%). Nearly forty times the difference for what sounds like an identical job. The reason is in the PDF specification: PDF has a JPEG image type and no PNG image type. A JPEG can be dropped in untouched; a PNG cannot — its pixels have to be decoded and then compressed into an image stream PDF understands, and PNG’s row-by-row prediction tricks do not survive the trip. No quality is lost (both sides are lossless), but the bytes cost 11.0% more. The practical advice is blunt: if you hold both a JPEG and a PNG of the same picture and you only need a PDF to send, feed the JPEG. The other way round, if that PNG carries transparency or is a screenshot or line art — content PNG is genuinely good at — then use the PNG, and the extra 11.0% buys edges with no ringing. As on the JPEG page, the page size equals the pixel count in points, not A4.
