Can I put several PNGs in one PDF?

Yes. Each image becomes its own page, in whatever order you arrange them before converting.

Will the images lose quality?

No. Each PNG is embedded losslessly, so pages are exactly as sharp as the originals.

Can I mix PNGs and JPGs?

Yes — use the JPG to PDF tool, which accepts both formats in the same batch.

Are my images uploaded?

No. The PDF is built entirely in your browser.

How to convert PNG to PDF

Sending someone eleven separate screenshots is a small act of hostility. Wrapping them in one PDF gives the recipient a single file that opens the same way on every device, prints in the right order, and attaches to any form that only accepts one document.

This guide covers converting PNGs to PDF free in your browser, including how to control page order and page size — the two things people most often get wrong.

Convert PNGs to a PDF in your browser

The PDF is assembled on your own device with pdf-lib, so nothing is uploaded and the result carries no watermark.

1Open the free PNG to PDF tool.
2Drag in every PNG you want included, or click to browse for them.
3Drag the images up or down until the page order is right.
4Pick a page size — A4, US Letter, or fit-to-image — then download your PDF.

Choosing the right page size

Pick A4 or US Letter when the PDF will be printed or shared as a document — every page comes out a consistent size with a margin, regardless of how big each screenshot was.

Pick fit-to-image when the PDF is only for viewing on screen. Each page matches its image exactly, so nothing is letterboxed by whitespace, though pages will vary in size if your images do.

A note on transparency

PDF pages are opaque, so any transparent areas in a PNG show the white page behind them. For screenshots, logos and diagrams that is almost always what you want. If you need the transparency preserved as transparency, keep a PNG or WebP copy alongside the PDF.
