How to turn a PNG (or a pile of them) into a PDF

By The CompressImages Team

Images are great until you have to send a bunch of them somewhere official. Five separate screenshots look messy in an email, won't print as a neat set, and some upload forms flat-out refuse anything that isn't a PDF. Rolling them into one document solves all three at once.

Drop your images into JPG to PDF — it takes PNGs too, despite the name — arrange them in order, and download a single PDF. One file, properly paginated, ready to print or attach.

Get the order right first

If you're combining several images, the sequence is the whole point. Screenshots of a process should read step 1, step 2, step 3 — not whatever order they happened to upload in. Drag them into place before you convert; it's much easier than redoing it.

A quick word on transparency

PNGs often have transparent backgrounds. PDF pages don't — they're white. So a logo that looked like it was floating on nothing will sit on a white page once converted, which is almost always what you want anyway. If you specifically need to flatten a PNG onto a solid background as an image, PNG to JPG does that instead.

If the PDF comes out heavy

High-resolution images make for a chunky PDF. If you're emailing it and the size is getting silly, a quick pass through Compress PDF trims it down without any visible difference on screen. Especially worth it if you've bundled ten or more images.

Tip — Scanning paper documents with your phone? Snap them, then convert the photos to PDF the same way — it's faster than hunting for an actual scanner, and the result is a proper multi-page document.

That's the whole trick. Scattered images in, one clean PDF out, and no more apologising for sending a dozen attachments.
