Compression runs locally on your device.

How it works

  1. 1Drop images (or a folder) onto the dropzone — files stay on your device.
  2. 2Pick a quality preset and (optionally) an output format. Auto picks the smallest modern format your browser supports.
  3. 3Click Compress. The browser's built-in encoders (and WebAssembly for PNG/AVIF) do the work.
  4. 4Download individual results or grab a ZIP — folder structure is preserved.

Frequently asked questions

Are my images uploaded to your server?
No. All images are processed locally in your browser using JavaScript and WebAssembly. Your files never leave your device, and we have no infrastructure that could receive them.
Can I compress multiple images?
Yes. You can drop a batch of images (or an entire folder) and download the compressed results as a single ZIP file with the original folder structure preserved.
Which formats are supported?
JPG, PNG, WebP and AVIF are supported when available in your browser. The Auto mode picks the smallest modern format your browser can encode.
Can I compress images to a specific size?
Yes. Use the Compress to KB tool to target 100KB, 200KB, 500KB, 1MB or any custom size.
Do I need an account?
No. There is no signup, no login, and no payment. The tool works as soon as the page loads.
