Input

Drop files here or Browse

Drag and drop works here too.

1–100 PNG files, 20 MB each and 150 MB combined. Order becomes page order.

The whole image fits inside the margins; narrow gaps show the background.

Whole points from 0 to 72 on every side of fixed-size pages.

PNG bytes go into the PDF unchanged with transparency intact: the background you pick is painted behind each picture, so see-through areas show your colour instead of the viewer's default. Everything runs in this tab; nothing is uploaded.

No PDF yet.

Add PNG files, arrange them, then convert.

PNG to PDF builds one ordered document from your PNG images while keeping what makes PNG special: transparency survives as a real soft mask, shown against the page background you pick — white, black, or your own hex colour. It is the tool to choose when nearly everything you have is a PNG and see-through areas must stay see-through rather than turning into grey boxes. Order the files, choose the page geometry and margin, then download a single PDF. Cells, logos and diagrams embed without recompression, so pixels and alpha channels arrive exactly as uploaded, and the run stays on your device throughout.

How to use PNG to PDF

  1. Drop 1–100 PNG files and drag them into page order.
  2. Pick page size, orientation, fit, margin, and the background behind transparent areas.
  3. Convert and download the single ordered PDF.

What you get

  • A single ordered PDF built from your PNG files.

  • A 1–100 file, 150 MB combined envelope, with PNG bytes embedded unchanged.

When to use PNG to PDF

  • Bundle transparent-logo artwork into a PDF where see-through areas stay white.
  • Collect PNG screenshots into an A4 document with even margins for review.
  • Assemble diagrams onto black pages for a dark-themed handout.

Frequently asked questions about PNG to PDF

What happens to transparent areas?

They stay transparent in the file and show the background you chose, because a solid rectangle is painted behind each picture. Nothing is flattened.

Can I use a custom background colour?

Yes. Besides white and black, a custom hex colour like #123456 is accepted and validated before anything runs.

Does PNG to PDF recompress my images?

No. PNG bytes embed unchanged, so pixels and transparency survive exactly as uploaded.

Is anything uploaded?

Nothing. Decoding, layout, and assembly run in your browser — in a background worker when one is available — and files are released on clear.
