About TGZ to 7Z Conversion
TGZ and 7Z (introduced 1999) are both archive / compression formats, but they differ in important ways. TGZ is a widely used file format. 7Z uses the LZMA2 algorithm for the highest compression ratios available.
When you convert TGZ to 7Z, the goal is to convert between formats quickly. Converting TGZ 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 TGZ file is decoded and re-encoded as 7Z. The conversion involves 4 steps: (1) your tgz file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in 7z format, (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.
