Tools / Compress images to PDF

Compress images to PDF

Combine photos or scans into a single PDF that is small enough to email or upload, in one pass. Compressing first and converting afterwards re-encodes every image twice and visibly degrades them for no extra saving — this does both together. Page order is yours to set, and nothing leaves your browser.

Runs entirely in your browser

About this tool

Turn photos or scans into a single compact PDF, compressing them on the way in — in one pass. This is the tool for making a set of images small enough to email or upload without ending up with a bloated document.

Doing it in one step matters. Compressing images first and then converting to PDF separately re-encodes every image twice, which visibly degrades them for no extra saving. This tool compresses and assembles together, so quality is preserved as much as possible for a given size. You set the page order, and nothing leaves your browser.

It is well suited to receipts, scanned forms, ID pages and multi-photo documents that have to fit under an attachment or upload limit. Because it runs locally, those sensitive documents stay on your device.

Frequently asked questions

Why compress and convert in one pass?
Because compressing images and then converting to PDF separately re-encodes each image twice, degrading quality for no extra size saving. Doing both together preserves quality for a given target.
Is this better than compressing images first?
Yes, for quality — a single combined pass avoids the double re-encoding that a two-step process causes.
Can I set the page order?
Yes. You arrange the images before converting, and they appear as pages in that order.
Are my documents uploaded?
No. Everything runs in your browser, so receipts, scans and other sensitive images stay on your device.
What is it best for?
Making photo-based documents — receipts, scanned forms, ID pages — small enough to email or upload as a single PDF.
