Compression with judgment

Full-screen comparator: click a photo and drag the divider to see original and result side by side.
Real weight on screen: every photo shows how much you saved, and the batch total adds up below.
WebP and AVIF: the formats that save the most, alongside good old JPG and PNG.
No uploads, no waiting: compressing in the browser is immediate because your files go nowhere.

Frequently asked questions

How much weight can I save?

It depends on the photo and the source format, but a camera JPG usually drops between 60% and 85% when converted to WebP at quality 82, with no difference you can see on screen.

Which quality should I choose?

Between 80 and 85 is the sweet spot: the difference stops being visible and the file drops a lot. Above 90 the weight climbs with no visible gain; below 70 you start to see banding in gradients.

Does compressing lose quality?

It discards information your eye cannot tell apart on screen. That is why you can compare before and after up close first: if you spot anything, raise the quality and you are done.

Can I compress many photos at once?

Yes. The quality setting applies to the whole batch and you download the complete result as a ZIP.
