How PZIP Compresses SQLite

SQLite files are B-tree page-based with fixed-size pages (1-64 KB). PZIP understands this structure and compresses different page components with specialized strategies. Free pages (deleted content) are eliminated. The result: smaller output than running LZMA on the raw file.

History of SQLite

Est. 2000Created by D. Richard Hipp

SQLite was created by D. Richard Hipp in 2000 as a self-contained, serverless SQL database engine. It's the most widely deployed database in the world — in every smartphone, browser, and IoT device. SQLite files use B-tree page-based storage with configurable page sizes.

Frequently Asked Questions

Does PZIP preserve SQLite database integrity?

+

Yes. 100% lossless — the decompressed file is byte-identical to the original. Every table, index, and page is preserved exactly.

What about WAL mode databases?

+

PZIP handles WAL, journal, and standard modes. For best results, run VACUUM before compressing to eliminate free pages.
