Squoosh
Compress images in your browser and compare quality before saving.
What it is
Squoosh is an image compression tool that runs in your browser. Open an image, adjust the compression settings, and compare the result with the original before saving.
Why it is selected
A smaller file is useful only if the image still looks right. Squoosh lets you inspect the visual differences alongside the file size, so you can decide how much compression a particular image can take.
Who it suits
Frontend developers and designers preparing website images, and writers reducing image sizes before uploading them to an article.
Useful for
- Comparing compression settings before publishing a photo or illustration
- Checking whether a smaller file still preserves the details that matter
Privacy note
Image compression happens on your device without sending the image to a server. The project’s privacy documentation also describes Google Analytics collection of visitor data and file sizes before and after compression.
