Some metadata may not survive
Your TAR file may contain Unix permissions, ownership, timestamps metadata. 7Z has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About TAR to 7Z Conversion
TAR (introduced 1979) and 7Z (introduced 1999) are both archive / compression formats, but they differ in important ways. TAR is a Unix archiving format that bundles files without compression. 7Z uses the LZMA2 algorithm for the highest compression ratios available.
Full Name: TAR uses Tape Archive, while 7Z uses 7-Zip Archive. Compression: TAR uses None (uncompressed), while 7Z uses Lossless. Typical File Size: TAR uses same as contents (no compression), while 7Z uses varies (best compression ratios available).
When you convert TAR to 7Z, the goal is to convert between formats quickly. Converting TAR to 7Z maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your TAR file is decoded and re-encoded as 7Z. The conversion involves 4 steps: (1) your tar file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in 7z format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you specifically need a 7Z file for your workflow. For the opposite direction, CocoConvert also supports 7Z to TAR conversion.
How to Convert TAR to 7Z
- 1
Upload .tar file
Select your TAR file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .7z
Set 7Z as the output format. The converter uses optimal settings based on the TAR→7Z conversion profile.
- 3
Convert
The server-side engine decodes your TAR file and re-encodes it as 7Z. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .7z file. Multiple output files can be downloaded together.

Does TAR to 7Z conversion affect quality?
Converting TAR to 7Z maintains high quality with CocoConvert's optimised encoder settings.
Which format has better compression, TAR or 7Z?
TAR uses none compression. 7Z uses lossless compression. The better choice depends on whether you prioritize file size or quality.
How long does TAR to 7Z conversion take?
Most conversions finish in seconds. Larger files or complex archive / compression content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is TAR or 7Z better for long-term storage?
7Z is better for archival since it preserves all original data.
