Install 9xconvert

Use the official 9xconvert download page to see the builds currently available for your device.

Desktop

Download the package for Windows, macOS, or Linux.
Open the package and follow the operating system prompts.
Launch 9xconvert.
On the first screen, create a UID or continue with one you already use.

Windows

Use the Microsoft Store build or the installer linked from the download page. Launch 9xconvert from the Start menu after installation.

The desktop build is code-signed. If SmartScreen appears anyway, choose More info → Run anyway.

macOS

Open the downloaded package, move 9xconvert into Applications when prompted, then launch it from Applications or Spotlight.

Linux

Download the Linux package shown on the download page. If your distribution requires it, mark the downloaded file executable before opening it.

Android

Install 9xconvert from Google Play, then open it and create a UID or continue with one you already use.

Local file conversion runs on your phone and does not use mobile data. The first account verification and network-based features still need a connection.

What needs internet?

After your UID is verified, local conversion and editing work without an internet connection. Account verification, updates, and From URL use the network because they contact an online service.

Next step

Continue with your 123sudo UID, then make your first conversion.
