RMVB to TAR Converter
Processing entirely on your device — large files may take a moment.
RMVB is RealMedia with variable-bitrate video — the format Asian fan-sub communities distributed dramas and movies in throughout the 2000s. TAR preserves the exact file tree and permissions that Linux tooling expects.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the RMVB format
RMVB is RealMedia Variable Bitrate — the 2000s fan-sub community's format of choice for distributing TV dramas and movies across dial-up-adjacent bandwidths. The VBR twist let action scenes take more bits than talking heads, which static-bitrate RM handled badly.
Conversion to MP4 is the standard migration: the RV40 video decodes through ffmpeg, and a modern H.264 re-encode is usually smaller at the same perceived quality.
+Strengths
- ✓VBR suited the bandwidth of its era
- ✓Huge corpus of Asian drama content
- ✓Decodes through ffmpeg
!Limitations
- −Mostly SD resolution content
- −RV40 codec support varies by build
- −Licensing strings in some files
About the TAR format
TAR (tape archive) is Unix's fifty-year-old answer to bundling: it concatenates files with headers into a single stream, preserving POSIX permissions, ownership and symlinks — but compressing nothing. It is the container half of the classic .tar.gz pairing and the native format of Linux source trees and backups.
Being pure bundling, TAR pairs with a compressor: gzip (the classic), bzip2, zstd. Alone, a TAR is the same size as its contents. Windows 10+ ships bsdtar, so even Windows can unpack it now — permissions aside, where NTFS has no room to be faithful.
+Strengths
- ✓Preserves Unix permissions and symlinks
- ✓Streamable: works over pipes and tapes
- ✓The standard of Linux distribution and backup
!Limitations
- −No compression by itself
- −No built-in encryption
- −Permissions meaningless on Windows filesystems
Why convert RMVB to TAR?
Converting makes sense where the strengths of TAR meet what RMVB cannot give you. Preserves Unix permissions and symlinks Meanwhile Mostly SD resolution content One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this RMVB to TAR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for RMVB to TAR?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting RMVB to TAR re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
