About Image Compressor

Image Compressor is a free tool for shrinking JPG, PNG, and WEBP image files — directly in your web browser. There's no sign-up, no watermark, and no limit on how many files you compress.

Why is it free?

Every compression here runs in your own browser using its built-in Canvas image processing, not a server we operate. Because we're not paying to process anything on our own infrastructure, there's no per-use cost to pass on — the site is instead supported by advertising.

Nothing you upload ever leaves your device

Every image is decoded, re-encoded, and made available for download entirely inside your browser's own memory. We never receive the file, because it's never sent anywhere — you can verify this yourself by watching your browser's network activity while you use the tool.

Who's behind this

Image Compressor is part of the LoomFile family of free, private, in-browser file tools. If you have feedback or run into a bug, see our Contact page.
