About Squoosh
Squoosh is an image optimiser that works in the browser. You open a picture, compare codecs and settings side by side, then save a smaller file.
What it does
You drop or paste an image, then see the original and the compressed version next to each other. Each codec and setting shows its effect on file size and quality. When you are happy with the result, you save the file. The app processes images on your own device, so the pictures do not leave it. It can be used offline after the first load.
Key features
- Compare codecs and settings
- Drag, drop or paste images
- Adjust settings for smaller files
- Processing happens on your device
- Offline use after the first load
Who it's for
Web developers and designers who want to reduce image weight before upload are the main audience. It also suits anyone who prefers not to send photos to an online service.
Pricing and good to know
Squoosh is open source under the Apache-2.0 licence, and the code is on GitHub. Because it runs locally, large images depend on your device's memory and speed. Very aggressive settings can lower visible quality, so compare the preview before you save.
