Squoosh compresses images using a range of codecs and lets you compare the output against the original before you save it. It runs in the browser, so there is nothing to install to start working on a file. It suits anyone who needs to shrink images for the web, an email or a document and wants to see how much quality is lost at a given setting. Open an image, adjust the compression options, and check the before-and-after view to decide what to keep.
Compress images with different codecs and compare the results side by side in your browser.
What you can do
Compress an image with several codecs and compare the results.
View the compressed image next to the original before saving.
Adjust compression settings to balance file size and quality.
Open images shared from other apps directly in the app window.
