Repack compressed TAR
Move between TAR, TAR.GZ, TAR.BZ2 and TAR.XZ without changing file contents. Use Repack compressed TAR locally with practical instructions, output settings and format limits.
Repack compressed TAR
Move a TAR archive between uncompressed TAR, TAR.GZ, TAR.BZ2 and TAR.XZ packaging while retaining its extracted file content. Use it when another system expects a particular TAR compression wrapper. Entries are read through the archive safety checks, so this is a content repack rather than a byte-identical metadata-preserving archive rewrite.
- Convert TAR.GZ into TAR.XZ
- Remove gzip compression from a TAR package
- Prepare a supported compressed TAR for another tool
How to use Repack compressed TAR
Choose a TAR-based source
Upload TAR, TAR.GZ, TAR.BZ2 or TAR.XZ. A file with a compressed TAR extension must actually expand to a TAR archive rather than unrelated compressed content.
Select the destination wrapper
Choose TAR or a supported gzip, bzip2 or xz compressed TAR format. Check that the receiving tool accepts the selected compression type before creating the package.
Repack the checked entries
Run Create result to read the bounded archive contents and package them again. Unsafe paths, encrypted inputs and symbolic-link entries are outside the supported workflow.
Verify files in the new archive
Download and inspect the output with a compatible archiver. Compare expected file names and contents with the source, rather than expecting identical archive bytes or preserved original metadata.
Understand the settings
- Output format
- Choose output format according to the result you need. Available choices: TAR; TAR.GZ; TAR.BZ2; TAR.XZ. The initial selection is TAR.GZ.
A different compression wrapper for delivery
A tool accepts TAR.GZ but the supplied package is TAR.XZ. Upload the TAR.XZ, select TAR.GZ and create the result. Inspect the repacked archive’s file list and representative contents before handing it to the receiving tool.
Check your result
Choose a file or enter text where available. Review the settings, create your result and download the new copy. Processing stays on this computer. Input and expansion limits apply; originals are never overwritten. Open the saved output in the app or workflow where you plan to use it. Check one representative result before repeating the same settings with more files. The original files stay unchanged.
What to know before you start
- Browser repacking supports TAR and TAR.GZ.
- Files are processed on this device. Browser memory and engine-specific limits apply. Save results before reloading.
- Processing stays on this computer. Input and expansion limits apply; originals are never overwritten.
- Upload one file with a combined size of at most 100 MB. The completed output must fit within 200 MB.
- Files are checked by the local engine; a matching filename alone is not proof of valid contents.
- Selections and completed jobs stay available while you navigate inside this tab. Use My files to revisit results. Reloading or closing the tab clears the workspace; download results you want to keep first.
Repack compressed TAR: common questions
Are the file contents converted?
No. The supported extracted file contents are packaged into the selected TAR wrapper without document or image conversion. The archive itself is rewritten, so its binary checksum can change even when the enclosed file bytes remain the same.
Are original TAR metadata fields preserved exactly?
This workflow reads checked entries and creates a new archive, so it does not promise byte-identical TAR headers or preservation of all original ownership, timestamp and permission metadata. Use it when file content and compatible packaging are the goals.
Can I use a plain .gz file?
This tool is specifically for TAR and the listed compressed TAR variants. Use the archive browser for a standalone gzip-compressed file, since a compressed stream does not necessarily contain a TAR archive or multiple member files.
What expansion limits apply?
The archive safety workflow bounds expansion to one hundred megabytes and one thousand entries, and rejects unsafe paths or unsupported entry types. A small compressed source can still exceed these limits once its content is expanded.
Does Repack compressed TAR upload files to another service?
Processing runs in this browser, on your device. Files and pasted input are not uploaded to a conversion server. The website and required engine assets must load first; large operations depend on available device memory.
Can I continue after changing pages?
