Compress JPG. Nothing leaves your device.

What a browser-side compressor gives you
18 of 20 vs TinyPNG
On our 20-image benchmark, PixSip's output matched or beat TinyPNG's file size on 18 images at comparable visual quality.
No uploads, no queue
Nothing is sent to a server, so there is no upload bar, no queue behind other people's jobs, and no per-image cost.
Inspect at 1:1
Every result gets a Compare view with a drag divider and full-resolution 1:1 zoom, where compression artifacts actually show up.
