smallest filesize for transparent single pixel image


I'm looking for the smallest (in terms of filesize) transparent 1 pixel image.

Currently I have a gif of 49 bytes which seems to be the most popular.

But I remember many years ago having one which was less than 40 bytes. Could have been 32 bytes.

Can anyone do better? Graphics format is no concern as long as modern web browsers can display it and respect the transparency.

UPDATE: OK, I've found a 42 byte transparent single pixel gif: http://bignosebird.com/docs/h3.shtml

UPDATE2: Looks like anything less than 43 bytes might be unstable in some clients. Can't be having that.


Solution

  • Checkout this blank.gif file (43 bytes). Less than 49 :D
