Questions

Are my files sent to any server? ▾

No. Weesize processes documents entirely inside your browser using JavaScript and WebAssembly. Your files never leave your device.

Is Weesize really completely free? ▾

Yes. Weesize is free, open source, and has zero limits, subscriptions, watermarks, or accounts required.

How does exact-size compression work? ▾

Our client-side engine iteratively optimizes image streams and metadata targets until the file reaches your requested KB size without degrading legibility.

Does it work offline? ▾

Yes. Once the page is loaded, you can turn off Wi-Fi or disconnect from the internet and continue compressing and editing files.
