Icon sets keep coming out huge, is this standard? The files within the ico container are very small. Is there anything I can do to reduce the file size of the icon set?

icoconvert.com -- multi-image to one icon, 6 very small files, ico came out to 135k!!

ImageMagick -- convert.exe image-16.png image-32.png fancy.ico -- individual file sizes total 1.5k, ico size 5.3k!

-- convert.exe sfp-16.png sfp-32.png sfp-48.png sfp-64.png sfp.ico -- 4 individual file sizes tiny, largest is 835 bytes, ico file size 31.2k!

While ImageMagick obviously did a better job than icoconvert as far as bucket size goes, still it seems like it is using a moving van to hold what should fit in a standard envelope. New project is counting every byte for mobile-first dev data considerations.

Any help please?

Thank you, Beth

This is due to the ICO format itself.

Instead of focusing on the favicon.ico file, a workaround is to enable GZip compression for .ico files in the HTTP server.
