Compress images
Reduce file size with no noticeable quality loss. Everything happens locally - nothing is uploaded.
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.
Features
- JPG, PNG and WebP supported

Everything happens inside your browser using JavaScript and WebAssembly. Your files are never uploaded to a server, never stored, and never seen by us.
