Question 1

Can I compress JPG to a specific file size?

Accepted Answer

Use the quality slider to control output size. Lower quality = smaller file. The compressed size updates in real-time so you can hit your target.

Question 2

Will compression make my photo look bad?

Accepted Answer

At quality 70-80%, most photos look identical to the original. Below 50%, you may notice artifacts, especially on text and sharp edges.

Question 3

Is my photo uploaded to a server?

Accepted Answer

No. Compression happens entirely in your browser using WebAssembly. Your photo never leaves your device.

Question 4

Can I compress multiple JPGs at once?

Accepted Answer

Yes. Drop up to 20 JPG files and compress them all in one batch. Download individually or as a ZIP.
