Repacking a RAR archive as TAR is about who has to open it and how small it needs to be on the way there. TAR (Tape archive) earns its place here: preserves Unix permissions, symlinks and directory structure exactly. RAR is a proprietary archive format known for recovery records and multi-part volumes. Creating it requires licensed software; opening it does not.

Every file is unpacked and repacked, so the contents are bit-identical — only the compression method and resulting archive size change. Unix permissions and symlinks survive only in formats that record them, and encrypted archives need to be unlocked before repacking.
What you gain with TAR: Preserves Unix permissions, symlinks and directory structure exactly.
Drop your RAR file above and Morphio decodes it locally, then re-encodes it as TAR using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
Open the RAR to TAR page, drop your archive on the drop zone and press convert. Morphio runs a WebAssembly archiver that runs entirely on your machine, so the RAR data never leaves your device and no server ever receives a copy.
Entries are repacked without touching their contents, so checksums of the inner files stay valid. Converting RAR to TAR only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
No. The content is remapped from RAR into TAR structurally, so nothing is re-compressed. Only features TAR has no way to express are left behind.
Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.
No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
