How do I convert RMVB to MP4?

Upload your RMVB file to LetsConvert, select MP4 (H.264) as the output format, and set your preferred resolution or bitrate if needed. Click 'Convert', wait for the process to finish, then download the MP4 file. The entire conversion runs online—no software install required.

Why should I convert RMVB to MP4 instead of keeping the RMVB file?

RMVB (RealMedia Variable bitrate) is an older, proprietary format with limited codec efficiency and compatibility. MP4 using H.264/HEVC is the global standard for video, supported by virtually every device, browser, and editing software. Converting also reduces file size thanks to more efficient compression, while maintaining visual integrity.

What happens to the original video quality and metadata during RMVB to MP4 conversion?

LetsConvert re-encodes the video track to H.264 and the audio track to AAC. Original resolution, frame rate, and audio channels are preserved. Bitrate is automatically chosen to balance quality and size—you can override it. Chained subtitles (embedded in RMVB) are extracted by default; you can optionally burn them into the video. Other metadata like title and tags is copied when possible.

Is RMVB-TO-MP4 free to use?

Yes, RMVB-TO-MP4 on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! RMVB-TO-MP4 works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
