Answers use saved listing facts and recorded sources.

What it does

Squoosh lets you open an image, adjust compression settings, inspect differences and save the result.

Open an image, adjust compression and compare fine text, edges and texture before saving the result. Squoosh suits a web asset whose smaller size still needs a visual check. The Apache-licensed app requires JavaScript. Its README says image processing stays on the device, while analytics collect basic visitor data, before/after file sizes and PWA installation details.

Evidence

The documented image-to-saved-result path includes adjustable compression and visual comparison for web assets. The reviewed passages do not detail codec/output settings or a bounded worked compression job, so75 is the lower controls/input-output anchor.

Limits: AI review of saved source passages. No hands-on test, human approval or automatic-provider checker receipt.

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.
