Heads up — Windows Defender might flag it: FCP bundles an FFmpeg binary and is compiled with PyInstaller, which are common false-positive triggers. Adding the install folder to your Defender exclusion list (the installer offers to do this automatically) is strongly recommended. The app makes zero outbound connections during conversions. For more details and help with false positives, please read the README available at GitHub.

FCP is free and will stay that way.

There are no ads, no premium tier, no tracking. If FCP saves you time, you can always buy me a coffee. It helps support development and lets me keep working on it between classes.
