how about

?

If this short base64 representation for 1px transparent gif is valid, it is far more better. bjrke, if it is really valid, could you explain why or give some reference to read. thank you in advance

try it, it is a 1px x 1px gif with a 1bit palette, created with gimp and encoded with base64 tool in linux.

That's great. Thank you. It seems there was lot of unnecessary metadata in the image, because new base64 is a discontinuous substring of the previous one. Thank you once again.

This is smaller

data:image/gif;base64,R0lGODlhAQABAAAAACw=

@HazemNoor - that shorter one seems to leave a placeholder border on some browsers and mobile devices. (even with all border CSS attributes set to none)
