About this tool
Re-encodes your image at a quality level you choose and shows the before and after size with the saving percentage. Compression happens in your browser using the canvas encoder, so private photos never reach a server.
How to use it
- Drop an image or choose a file from your device.
- Move the quality slider and watch the estimated size update.
- Download the compressed image when the preview looks right.
Frequently asked questions
How much smaller will my image get?
It depends on the source. Photos often drop 50–80% at quality 0.75, while already optimised files may save very little; the tool shows the real result before you download.
Are my images uploaded?
No. Decoding, re-encoding and download all happen in your browser. The server only delivers the page.
