Add your VSIX file
Drop one or more .vsix files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Repacking a .vsix archive as .tar moves the same files into a container with different compression and compatibility trade-offs. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Repacking a .vsix archive as .tar moves the same files into a container with different compression and compatibility trade-offs. A .vsix file is the extension package used by Visual Studio and, with a different manifest inside, by Visual Studio Code. It is an Open Packaging Conventions ZIP carrying an extension.vsixmanifest, the extension's own files, and the content-type map the installer reads in order to place them.
A .tar file is a tape archive: many files and directories laid end to end in a single uncompressed stream, preserving Unix permissions, owners, and symlinks. It bundles but does not compress — that job is delegated to gzip, bzip2, or xz layered on top. For this route the practical draw is exact preservation of Unix metadata that other archive formats drop and dead-simple, fully streamable structure — balanced against uncompressed on its own, so bare .tar files are as large as their contents, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .vsix, two different manifest conventions share the extension, which regularly confuses tooling. Switching to .tar buys you exact preservation of Unix metadata that other archive formats drop, which is why it is the better fit for source code distribution across the Unix world. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Visual Studio extension (.vsix) | TAR archive (.tar) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | the container is Open Packaging Conventions, so it always includes a [Content_Types].xml declaring how each file extension is handled | each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries |
| Strongest at | inspecting an extension's declared activation events and dependencies before installing it | source code distribution across the Unix world |
| Weak spot | two different manifest conventions share the extension, which regularly confuses tooling | uncompressed on its own, so bare .tar files are as large as their contents |
| Metadata | identity, display name, version, publisher, and supported product ranges live in extension.vsixmanifest, with VS Code duplicating much of it in package.json. Both are ordinary files that extraction preserves | records owner and group both by name and numeric id, permission bits, and modification times — extraction as root can restore ownership faithfully |
Drop one or more .vsix files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Select .tar in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TAR is selectable, the route is real and validated.
Press Convert. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TAR file. Outputs keep the original filename with the .tar extension.
Since vsix is container-oriented and tar is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .tar itself requires.
Yes — the .vsix file is processed inside your browser tab and never uploaded. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser. Close the tab and the file is gone from memory.
Every Linux distribution, macOS, and the BSDs ship tar as a core utility, and Windows 10 and later include bsdtar at the command line. Graphical tools like 7-Zip open tarballs too, though they may need two passes for compressed variants.
It depends on the content: each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries. Convert one representative file first and compare before batch-processing a large set.
In .vsix, identity, display name, version, publisher, and supported product ranges live in extension.vsixmanifest, with VS Code duplicating much of it in package.json. Both are ordinary files that extraction preserves. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
