Why Use an Image Compressor?

Large image files slow down websites, clog email inboxes and eat up storage. Compressing images before you share or upload them is one of the highest-impact optimisations you can make — often reducing file sizes by 60–95% with no visible loss in quality.

This tool handles every common image format: JPG for photos, PNG for graphics and logos, WebP for modern web use, GIF for animations and SVG for icons. You can mix formats in one batch — drop in a collection of JPGs, PNGs and WebPs at the same time and compress them all in one go.

Transparency is fully supported. PNG and WebP files with transparent backgrounds are compressed without flattening — the alpha channel is preserved throughout. Only when you explicitly choose JPG as the output format will transparent areas be filled with white, because JPG does not support transparency.

Because all processing runs directly in your browser using the HTML5 canvas API, your images never leave your device. There is no server upload, no account required and no file size limit imposed by a server.

Frequently Asked Questions

Common questions about online image compression

Which image formats does this compressor support?

JPG, JPEG, PNG, WebP, GIF and SVG. You can mix formats in one batch — upload a combination of file types and compress them all at once.

Does image compression keep transparency?

Yes, for PNG and WebP output. The alpha channel is fully preserved. If you export to JPG, transparent areas are filled with white because the JPG format does not support transparency.

Is this image compressor really free?

Yes, completely free. No sign-up, no watermark, no hidden limits. Compress as many images as you need.

Do my images get uploaded to a server?

No. All compression runs directly in your browser. Your images never leave your device, so they stay completely private.

How do I compress to a specific file size?

Use the Quick Target buttons (100 KB, 200 KB, 500 KB, 1 MB, 2 MB) and the tool automatically finds the right quality to hit that size. Or type any custom KB value in the Custom size box.

Can I compress multiple images at once?

Yes, upload up to 10 images at once. All formats can be mixed in one batch. Download all compressed files as a single ZIP.

Can I use this on my phone?

Yes. The tool is fully mobile-friendly and works on iPhone, Android, iPad and any modern browser without installing anything.
