Common questions

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.

Can you guarantee it will be under 100KB?

If the content allows it, yes. You can use the slider to reduce quality until the target size is reached.

Does this work offline?

Yes. Once the page is loaded, you can disconnect from the internet and the tool will still work perfectly.
