Frequently asked questions

Will the image really be under 25 KB?

Yes. The tool searches for the best quality that fits and checks the result. We count 1 KB as 1,000 bytes, so the file also passes strict upload checks.

Why does my photo get smaller dimensions?

A large photo cannot reach 25 KB with quality alone without looking blocky, so it is also scaled down a little. The new size is shown with the result.

Can I compress several images at once?

Yes. Add up to 50 images; each one is made to fit the limit and you can download them as a ZIP.
