...small but actually looks like something:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAIAQMAAAD+wSzIAAAABlBMVEX///+/v7+jQ3Y5AAAADklEQVQI12P4AIX8EAgALgAD/aNpbtEAAAAASUVORK5CYII

Note that with Base64 you can usually get away with trimming any = from the end of the string as they are just padding. ☺️

Tried the tool in the link with the bare minimum settings of 1, 1, 1 and the result was:

Does it solve your task?

evnchn commented Jan 12, 2026

Elected to use https://gist.github.com/ondrek/7413434?permalink_comment_id=4693141#gistcomment-4693141, but then realized that R0lGODl should be image/gif

@RamonFLstate you may want to change the comment above.

evnchn commented Jan 12, 2026

Oh so the root-cause is that the service mentioned in https://gist.github.com/ondrek/7413434?permalink_comment_id=5209693#gistcomment-5209693 (https://yulvil.github.io/gopherjs/02/) returns PNG (iVBOR) no matter what you set it to in the frontend
