What would you like to do next?
Compress images before you upload or publish
Large images slow down pages, fill inboxes and often fail upload limits. This image compressor reduces file size by resizing oversized images and exporting a compact JPEG or WebP version. You can choose a maximum width and quality level, then compare the original and compressed sizes before downloading.
Private compression for everyday images
Because the file is processed in your browser, it is a good fit for client drafts, personal photos, support screenshots and other images you do not want to send through a third-party compression server.
Frequently asked questions
Which formats can I compress?
The tool accepts common browser-readable image files such as JPG, PNG and WebP, then exports JPEG or WebP.
Does compression reduce dimensions?
It can. Set the maximum width to keep large photos from staying unnecessarily huge.
What quality setting should I use?
Around 75 to 85 percent is a good start for photos. Lower values save more space but may show more compression artifacts.
