Your files stay yours because they never leave your device

Many online tools upload your files to their servers to work on them. Here it is the other way around: the work happens in your own browser, so we never receive or store your files.

  1. Choose your file

    Pick it on your device or drag it onto the page. Only your browser opens it.

  2. It is processed in your browser

    Your own device does the work. Nothing is sent to any server.

  3. Download the result

    Save it straight to your device. We never had a copy, so there is nothing to delete.

Many other tools

Your file travels to another company’s server and has to come back.

Here

Your file stays on your device the whole time.

Fast, because there is nothing to upload

With other tools, a big file has to be uploaded to a server and downloaded again before you can use it. Here the file does not travel: you only wait for your device to process it, which usually takes a few seconds.

  • No upload waitBig files do not have to travel to a server first.

  • No queuesYour device works on your file alone, not in a line with other people’s files.

  • Your connection barely mattersBecause your files do not travel, the speed of your internet has little effect.

Illustration. Real times depend on your file, your device and your connection.
