How to compress
an image.

Everything you need to make your images work harder, in three calm steps.

01

Choose an image

Drop, browse, or paste a photo, illustration, or asset. No account or complicated setup.

02

Set your intent

Choose a web-friendly format, trim dimensions, or let Auto find the smallest sensible result.

03

Download the smaller file

Compare the result, download one image, or bundle the whole batch into a local ZIP.

PRIVATE BY DEFAULT

Compression happens locally in a Web Worker. Your images never become an upload, a log entry, or a cloud file.

ABOUT THIS TOOL
