We have checked Squoosh 160 times since 11 Sept 2026, and it answered every time. Its visible text has not changed since we started watching.

What it does

An image compressor with a split-screen view so you can see the original and the compressed result at the same time, across different codecs and quality settings. The comparison is what makes it useful — you can find the point where quality visibly breaks rather than guessing at a percentage.
