Getting started
- Open squoosh.app and add the image from your device.
- Choose an output format and quality, resize if needed, and compare the result with the original in the preview.
- Download the compressed file and check it where you will use it before replacing the original.
Decision points
- Use it for careful one-by-one compression; the sources do not describe batch processing, so with many files look for a tool that documents batch support.
- Pick the output format by where the file will be used, and check that the target app, site or browser opens that format.
Limits
- The sources say image data stays on your device, but they do not list supported input formats such as HEIC, a maximum file size or batch use; test your own file first.
- The README says the app collects basic analytics such as before and after image size values and PWA install details; the image itself is not sent.
- The pages reviewed do not describe offline use; the README only mentions that the app can be installed as a PWA.

Do I need an account for Squoosh?
The pages reviewed do not mention an account or sign-in step. If you rely on that, check the site yourself.
Can Squoosh compress many images at once?
