User Guide


gzip enables gzip compression if the client supports it. By default, responses are not gzipped. If enabled, the default settings will ensure that images, videos, and archives (already compressed) are not gzipped.

Note that, even without the gzip directive, Caddy will serve .gz (gzip) or .br (brotli) compressed files if they already exist on disk and the client supports that encoding.



The plain gzip config is good enough for most things, but you can gain more control if needed:

gzip { ext extensions... not paths level compression_level min_length min_bytes }


Enable gzip compression:


Enable very fast but minimal compression except in the /images and /videos folders (note, however, that images and videos will not be gzipped anyway):

gzip { level 1 not /images /videos }
