I need a way to convert base63 to image without any extension

base63 ?

To answer your question, we would be doing it already if it were possible.

sorry base 64

I half managed to implement it with a tag (html appearance) and an internet component with htnl decoding. Unfortunately, I didn't get the picture I wanted. I only got one square of one color.

(I convert the image first with an extension, but since I would like the image to be returned to an iOS device, I cannot use this to convert it back)

You could post a file to a server running php, convert the file to base64 there, then return the base64 to the app...
