WEBM to TAR Converter
Processing entirely on your device — large files may take a moment.
WebM Video and TAR Archive exist for different jobs: WebM is Google’s royalty-free web video format (VP8/VP9 + Opus). It is small, streams beautifully, and every modern browser plays it natively. TAR preserves the exact file tree and permissions that Linux tooling expects.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How WEBM compares to TAR

About the WEBM format
WebM is Google's royalty-free video format for the web: a Matroska subset carrying VP8/VP9/AV1 video with Vorbis/Opus audio. YouTube serves most non-premium playback in VP9 WebM, and HTML5 `<video>` plays it natively in every modern browser — no licensing math required.
Efficiency is the selling point: VP9 and AV1 match or beat H.264/HEVC at the same quality for typical web content. Hardware decode is now widespread, though older Safari versions and some TVs remain the compatibility floor.
+Strengths
- ✓Royalty-free codecs (VP9/AV1, Opus)
- ✓Native HTML5 video support
- ✓Efficient at web bitrates
!Limitations
- −Weaker support on older Safari/TVs
- −Not the default for camera or editor workflows
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 WEBM to TAR?
There is a concrete reason this conversion exists: Weaker support on older Safari/TVs TAR sidesteps that — Preserves Unix permissions and symlinks If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this WEBM 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 WEBM 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.
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.
Does converting WEBM 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.
