Is it possible to change the zlib-flate compression level?

Question

I use the zlib-flate compression utility.

Is it possible to compress at different levels. The man page information is pretty vague.

If not is there an alternative utility that allows you to compress using zlib at different levels?

Answer 1

pigz -z# < FileToCompress > CompressedFile

Where # is the compression level.

Answer 2

zlib-flate

No, this utility can't do different levels of compression.

Alternatives

Sadly, I did not find an alternative of zlib in which you can set compression level, try:

• xz (man page) - you can set compression level

• bzip2 (man page) - you can set compression level

• gzip (man page) - you can set compression level
