About this tool

Make JPG, PNG and WebP images dramatically smaller without visibly hurting quality. The compression runs locally in your browser using the same encoders that power modern photo apps, so your photos never leave your device.

Smaller images mean faster websites, lower mobile data bills, and email attachments that actually go through.

Frequently asked questions

Will compression ruin my photos?

Quality 80-85 is visually identical to the original for almost all photos but typically 50-70% smaller.

Is PNG compression lossless?

Yes, PNG is re-encoded losslessly. JPG and WebP use lossy compression you can tune.

Are my photos uploaded?

No. Compression runs entirely in your browser.
