Join video parts into one file

ConvertBuddy is designed for consecutive recording parts that use compatible video and audio settings. Add the parts in order, run the compatibility check, and save the joined MP4 directly to your chosen location.

For compatible streams, the fast join workflow avoids unnecessary full-video re-encoding.

Keep important original files and verify the joined result before deleting or replacing anything. Use of ConvertBuddy tools is subject to the Terms of Use.
