Why Convert RM Files?
RM (RealMedia) was built for late-1990s streaming and barely plays anywhere today. Convert to MP4 to make old recordings watchable on modern devices.
RM files require RealPlayer, which is effectively obsolete. Converting to MP4 removes that dependency so the video just works.
Convert RM to MP4 or MOV for smooth import into current editing software, so archived footage can be re-cut and reused.
RM won’t upload to modern video sites or messaging apps. Convert to MP4 for universal sharing and streaming.
Migrate RM recordings to MP4 to keep them accessible for the long term, safe from disappearing codec support.
Convert RM video directly in your browser — no desktop apps, no plugins. Files up to 10 MB are always free, and all videos are deleted from our servers within 24 hours.
