Compress and download
Press Compress, see how much you saved, then download each image or a ZIP of all of them.
About Compress JPEG
JPEG compression throws away detail your eye can't see. Phone cameras save at very high quality, so re-saving at 75–85% typically cuts the size by 60–90% with no visible change.
Very large photos are also scaled to a sensible size if you choose a maximum width, which saves even more.
Frequently asked questions
Are my images uploaded?
No. Compression happens in your browser on your own device. Your photos are never sent to a server.
What quality should I use?
80% is a great default. Go down to 60–70% for the web, or up to 90% for printing.
Is JPG and JPEG the same?
Yes. They're the same format; the shorter extension comes from old Windows versions.
