What is Squoosh?

Squoosh is a browser image optimizer for reducing file size, comparing codecs, and previewing quality changes before saving the result.

What stands out

Drop or paste an image, compare the original and compressed versions side by side, then adjust dimensions, quality, and format settings. Processing happens locally on the device and the finished image can be downloaded immediately.

Questions about Squoosh

Does Squoosh upload my images to a server?

No. The official app states that image processing happens locally, so opened images do not leave your device.

Can I compare compression settings before downloading?

Yes. The split preview lets you inspect visual differences and file sizes while changing codecs and quality settings.

Do I need to install Squoosh or create an account?

No installation or account is needed. Open the web app, add an image, choose the settings, and save the result.
