Image Compressor
Shrink JPG, PNG, and WebP files without losing visible quality.

- Are my images uploaded to a server?
- No. Compression runs entirely in your browser using the Canvas API. Your images never leave your device, which also means there's no upload wait and no file-size limit imposed by a server.
- Will compressing reduce image quality?
- Some quality is traded for smaller file size, which is how compression works. At the default 80% quality setting, the difference is rarely visible to the eye, even though the file can shrink by 60–80%. You can raise the quality slider if you need a closer match to the original.
- What's the difference between JPG, WebP, and PNG output?
- JPG and WebP use lossy compression and produce the smallest files — WebP is usually 25–35% smaller than JPG at the same visual quality. PNG is lossless, so it preserves transparency and exact pixels, but files stay larger.
- Is there a limit on how many images I can compress?
- No daily limits. Since everything runs on your device, you can compress as many images as your browser can handle in one session.
