Data files

Parquet​

pip install 'filerepack[parquet]'    # or filerepack[data]
filerepack repack data.parquet
filerepack repack data.parquet --ultra   # zstd level 22

SQLite and spatial containers​

VACUUM on SQLite. .db still requires the SQLite format 3 header.

filerepack repack notes.sqlite
filerepack repack map.gpkg
filerepack repack tiles.mbtiles

Columnar and scientific​

pip install 'filerepack[data]'
filerepack repack table.orc
filerepack repack events.avro
filerepack repack frame.feather

HDF5 and NetCDF need h5repack and nccopy:

filerepack repack model.h5
filerepack repack grid.nc

Fonts​

pip install 'filerepack[fonts]'
filerepack repack icon.woff2

WOFF/WOFF2 also work via woff2_compress / woff2_decompress when fonttools is missing.

Compressed streams​

gzip, xz, bz2, zst, brotli, lz4, lzip, lzma, lzo, and Unix .Z are recompressed with the matching CLI (pigz is preferred for gzip). If the payload is a tar, the tarball is walked first — see Archives.

filerepack repack dump.json.gz
