Check it in your Network tab

You don’t have to trust a privacy promise. Open your browser’s developer tools, switch to the Network tab, then import, edit, and export a file. You’ll watch Klipzo load its own code — and not one byte of your photo or video leaves your device.

DevTools → Network → edit a file → 0 uploads

Frequently asked questions

Is Klipzo really free?

Yes. Every feature is free with no account, no watermark on your exports, and no paid tier. Klipzo is supported by ads on the surrounding guide pages, not by charging you.

Are my photos and videos uploaded anywhere?

No. All editing happens inside your browser on your own device. Your files are never sent to a server, to us, or to any third party — that is the core promise of Klipzo.

Do I need to create an account?

Never. There is no sign-up, no login, and no user database. You open the editor and start working immediately.

What happens to my files when I leave?

Your work lives only for the current session. Klipzo uses on-device scratch storage so a big file survives an accidental refresh, and you can wipe everything at any time with the ‘Clear session’ button. Nothing persists across devices because nothing ever leaves your device.

Which browsers work best?

Photo editing works in any modern browser. For heavy video export, desktop Chrome or Edge give the fastest results thanks to hardware-accelerated WebCodecs. Klipzo detects your browser’s capabilities and falls back gracefully, telling you honestly if a specific export isn’t supported.
