Recently I released a webapp to fix a problem I faced. I can paste any image from my clipboard (mostly screenshot in my case) to get its base64 version so I can integrate it directly in any markdown: https://paste64.vercel.app/
Seems like a fun learning project, but in the real world it's very counterproductive. You can obtain the base64 representation of the current clipboard contents very quickly using a single terminal shell command.
We must have very different definitions of "counterproductive". Sure, if you have mental space to remember the commands to generate the base64 via a terminal then more power to you. For the rest of us that would rather store a bookmark and/or might not always have access to a *nix environment for running shell commands this seems like a great solution. Either way it is far from "counterproductive".
