How to encode an image to base64 with minimal code?

Question

Image processing

Greetings.
There is an image in base64

data:image/gif;base64,R0lGODlhBwAKAMIEAICAgJmZmbOzs/f39////////////////yH5BAEKAAcALAAAAAAHAAoAAAMWSDPUGoE5AaIj1M4qMW+ZFDYD1ClnAgA7

It has a white background. I need to change it to the background color #f2f2f2. I change in Photoshop in various formats. I insert it into the online converter and instead of a short record, a very large record appears

Please tell me how to save, with what parameters to make the record short?

Answer 1

ran the image through tinypng, converted.
I hope you understand that it all depends on the size of the image itself? You can also remove meta tags.

Answer 2

Can't you set the background without an image?

Answer 3

You need to compress correctly in Photoshop or another graphic editor. The converter has nothing to do with it.
