Extract text from Zstandard compressed files (ZST)
To convert ZST compressed files to another format, you need Zstandard or other Compressed software.
To convert other file formats to the "Compressed Archive" file type, you need software like Zstandard or a similar tool.
The .zst file extension is primarily a Zstandard compressed data file. Developed by Meta (Facebook), this format provides real-time, lossless data compression that vastly outperforms older algorithms like zlib. It is heavily used by system administrators and developers for massive database dumps, system logs, and Linux package distributions (often seen as .pkg.tar.zst). You can decompress these files using the official Zstandard CLI, or modern desktop archivers like 7-Zip and PeaZip.
The main disadvantage of the .zst format is its poor native support on consumer operating systems. Default tools like Windows File Explorer and macOS Archive Utility cannot open or extract it. This leaves non-technical users unable to access the packaged files without installing third-party software or learning command-line arguments. Furthermore, because .zst is strictly a compression wrapper, users often do not know what file type (such as a CSV or SQL file) is actually inside until they extract it.
To share this data easily, you should extract the .zst file and repackage the contents into universally accessible targets like ZIP, TAR, or GZ. No internal data is lost during extraction, as the format is completely lossless.
Because it requires specialized decompression libraries, this file format is difficult to open or convert for the average user without the right software. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible. (Note: In rare cases, a .zst file might be an uncompressed photovoltaic test data ZIP from HT Instruments or a save state from the ZSNES emulator)..
Convert.Guru analyzes your ZST file, detects the exact format, and lets you read the text inside.
Users also converted DEM, DEMO, CDW, PLAN, SIG, ZSTD, ZIP, TZST, PDF, ZTD, G3D, TXT and XMCD files.
If you want to convert ZST file to GZ, ZIP, VMDK, CSV, QCOW2, DEM, OVA, ISO, RAR, 7Z, TAR or BZ2, you can use Zstandard or similar software from the "Lossless Data Compression" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to ZST, try Zstandard or another comparable tool in the "Lossless Data Compression" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ZST converter.
