svgcleaner could help you to clean up your SVG files from the unnecessary data.
A complete documentation can be found here: https://github.com/RazrFalcon/svgcleaner/blob/master/docs/svgcleaner.adoc
USAGE:
svgcleaner [FLAGS] [OPTIONS] <in-file> <out-file>
<FLAG> can contain values: true, false, yes, no, y, n
EXAMPLES:
clean a file with default options:
svgcleaner in.svg out.svg
clean a file with custom options:
svgcleaner --indent=2 --paths-coordinates-precision=5 --join-arcto-flags=yes in.svg out.svg
clean a file without default options:
svgcleaner --no-defaults --remove-comments=yes in.svg out.svg
clean a stream using UNIX pipes:
cat in.svg | svgcleaner -c - > out.svg
FLAGS:
-h, --help Print help information
-V, --version Print version information
-c, --stdout Print result to the standard output
--no-defaults Reset default flags to 'no'
--multipass Clean a file multiple times
--allow-bigger-file Allow bigger file
--copy-on-error Copy an original file to the destination on error
--quiet Show only warnings and errors
