How to convert RM to MP4

  1. Add your RM videos

    Drop RM (RealVideo, RMVB) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. MP4 is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.

  3. Download

    Save the MP4, or download everything as one ZIP if you converted several files.

RM to MP4: what to expect

RealMedia was one of the first formats for streaming video, and clips from the late 1990s and 2000s are still found in it. Almost nothing plays RM today, while MP4 plays on every device.

The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.

This pair uses the compatibility engine, ffmpeg built for the browser, because RM is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.

RM vs MP4

RM

RealMedia video

RealMedia was an early streaming format: RealPlayer played .rm files over dial-up and broadband in the late 1990s and 2000s, and .rmvb is its variable-bitrate variant. Old news clips, music videos and downloads are still found in it.

Opens in VLC and other FFmpeg-based players; no phone or browser

MP4 video

MP4 is the video container everything plays. It normally holds H.264 video and AAC audio, a pairing that phones, browsers, TVs and social networks all accept.

Questions

Are my videos uploaded anywhere?

No. The RM to MP4 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting RM to MP4 reduce quality?

It depends on what is inside the RM. When its video and audio are already in a form MP4 can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.

Can I convert several RM files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert RM to MP4 on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the RM file, press Convert and save the MP4. There is nothing to install.

Is there a file size limit?

Yes. RM to MP4 runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
