I think that selecting the compression ratio for ZIP files is a different thing, for a few reasons: 1. It's mostly heritage, from when we had slow CPUs and small hard disks. 2. A ZIP is an archive of multiple files, not compression of a single file. 3. Selecting different options actually used different compression systems, which yielded different results._ > >

I agree with this, but presumably GDI+ will be available on portable devices with less CPU since it forms the basis for System.Drawing.

Well, gzip works on one file and offers the same facility. IIRC, PNG uses the same algorithm as gzip.

I’m not sure about this - I think the different options affect the size of the lookahead buffer for the deflate algorithm where a bigger buffer may give better compression but will require more processing.
Interesting discussion for a cold Thursday morning. :o) Brrrr…just started trying to snow too.
