zibr

====

zipr is a command-line utility that repacks compressed ZIP files into

"stored" ZIP files (ZIP without compression) or PNG files into

uncompressed, but valid, PNG files, and then compresses the result

with brotli. These smaller files may be served by a web server in

response to requests with `Accept-Encoding: br` to save traffic.

    Repack ZIP or PNG files with brotli

    Usage: zibr infile [outfile]

    -c int

            brotli compression level (0 - 11) (default 11)

    -utf8

            make sure repacked ZIP files have UTF-8 encoding even if the original doesn't

Example:

    zibr file.zip

will produce "file.zip.br".

Example:

    zibr file.png

will produce "file.png.br".

If passed -utf8 flag, ZIP files repacked with zibr will have UTF8 flag set,

even if the original doesn't. This is not useful for compression, it's just

a fix for annoying macOS ZIP packer behavior which doesn't set the flag,

while encoding file names in UTF-8, making some decompressors (such as

The Unarchiver) sometimes detect a wrong encoding, mangling file names

(as a maker of [Mémoires.app](https://www.codingrobots.com/memoires/), I've

been burned by that.)
