Nothing is uploaded. Nothing leaves this tab.

No image to hand?

Start with a sample and watch the file size fall.

Small

Smaller files load faster. Pixpress strips away bytes you cannot see and keeps the detail you can.

A settings panel with a quality slider and preview tiles

Simple

Open, compare, save. Then dig into the encoder settings whenever you want to squeeze out more.

Private

No uploads, no accounts, no round-trips. Compression is done by WebAssembly running inside this tab.
