RMVB was hugely popular for sharing video in the 2000s, especially in Asia. With RealPlayer abandoned, converting RMVB archives to a modern format is the only way to keep them watchable.
MKV is the archivist's container of choice - open, flexible, and able to hold virtually any codec, subtitle, and audio track.
Our converter reads the RMVB file and produces a clean MKV file you can use anywhere. The first conversion loads our WebAssembly conversion engine (about 30 MB, cached afterwards) - then everything runs locally on your device.
Most online converters upload your RMVB file to a server for processing. Fublix doesn't - the conversion runs entirely inside your browser, and your file never leaves your device.
Free, unlimited, no watermark, and no registration required.
