Compress Image
Reduce JPG, PNG or WebP file size by re-encoding with adjustable quality — right in your browser.
What it does
Compress Image makes the file smaller by re-encoding what is inside it, not by zipping it up. You choose how hard to push, and the size you end up with depends far more on what the file contains — photographs, scans, flat graphics — than on how long it is.
When you need it
Almost always an upload limit: a mail server that bounces anything over 10 MB, a portal that refuses the attachment, a form that silently fails, or a page that loads slowly because its images were never resized.
Limits and caveats
Compression is lossy at the stronger settings, and quality that has been thrown away cannot be recovered from the output — keep your original. A file that is already compressed will barely shrink, and that is the format working correctly, not the tool failing. Everything happens in your browser, so the file never leaves your device.
