Compress image
Choose a picture, pick JPEG or WebP, and set the quality. The tool shows the original size, the new size, and how much you saved before you download anything.
The compression happens in your browser, so the photo is never uploaded.
Your image stays on this device. It is processed in your browser and never uploaded. There is no account and no daily limit.
How to use this tool
- Choose an image, or drop it on the box. It stays on this device.
- Pick JPEG or WebP and move the quality slider. Lower quality makes a smaller file; 70–85 is a good balance for photos.
- Press Compress image, compare the sizes, and download the result. If the new file is not smaller, try a lower quality or WebP.
Questions
How much smaller will my image get?
It depends on the picture and the quality you choose. Photos often shrink by half or more at quality 75–85. A file that is already compressed, or a small simple graphic, may shrink little or even grow, and the tool shows that.
JPEG or WebP: which should I choose?
WebP is usually smaller at the same visual quality and works in current browsers and most apps. JPEG is the safest choice when the file must open everywhere.
What happens to transparent areas?
JPEG cannot store transparency, so transparent areas are filled with white. WebP keeps transparency.
