Smaller images, less hassle
Large photos slow down websites, fill up storage, and bounce off email size limits. This compressor re-encodes your JPG, PNG and WebP images at a quality level you choose, cutting file size while keeping them sharp. Everything runs locally in your browser with the Canvas API — there is no upload step and no server in between, so your originals never leave your device.

Your images stay private
All compression happens directly in your browser. Your images are decoded and re-encoded on your own device with the Canvas API and are never uploaded to any server. We collect only anonymous, aggregated usage statistics (such as how often a compression starts or succeeds) to improve the tool — never your images, filenames, or any personal data.
Verify it yourself: Open your browser DevTools → Network tab and run the tool: no request ever carries your file. Everything happens on your device.
FAQ
- Are my images uploaded anywhere?
- No. Compression runs entirely in your browser, so your images never leave your device.
- How much smaller will my files get?
- It depends on the image and the quality you choose. Photos often shrink by 50–80% with little visible difference, especially when exported as WebP.
- Should I use JPG or WebP?
- WebP usually produces smaller files at the same quality and is supported by all modern browsers. Choose JPG if you need maximum compatibility with older apps.
- Will compression reduce image quality?
- JPG and WebP use lossy compression, so there is some quality loss at lower settings. Use a higher quality value to keep more detail.
- Can I compress many images at once?
- Yes. You can add many files together and compress them all in a single batch.
- Can I compress a PNG?
- Yes. PNGs are decoded and re-encoded to JPG or WebP, which usually gives a much smaller file than the original PNG.
- Is it really free?
- Yes. There are no watermarks, sign-ups, or file-size limits beyond what your device can handle.
