Checking publication status...LOCAL ARCHIVE TOOL / SAFE TAR EXTRACTION
Inspect and extract regular files from a checksum-validated TAR archive with bounded expansion and flattened safe download names.
Step 1 / source
Choose a TAR archive you own or are authorised to inspect.
Checking publication status...This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.
The converter creates a separately named output. It never writes back into the source file.
One .tar file up to 50 MB, with at most 200 regular files and 100 MB expanded data. Links, devices, and special entries are rejected.
Plain-language method
Nirmion verifies each TAR header checksum, reads regular USTAR-style entries plus bounded PAX or GNU long names, ignores directory records, rejects links and special types, and flattens path components into collision-safe filenames.
Use an uncompressed .tar file, not .tar.gz or .tgz. Only inspect archives from a source you trust or have permission to access.
There are no extraction switches. The 200-file and 100 MB expanded limits apply before files are offered for download.
Files are listed individually so you can download only what you need. Original directory hierarchy is not recreated by the browser.
Useful when
Before converting
Know the boundary
Permissions, owners, timestamps, links, devices, sparse files, and folder hierarchy are not restored. A link or special entry rejects the archive rather than being approximated.
Quick answers
The safe browser policy is narrower than command-line tar.
No. This route accepts uncompressed .tar only.
Browser downloads cannot safely recreate arbitrary source paths, so path components are flattened.
Links can redirect extraction paths. This release accepts regular files only.
