Yes, I use also steganography, but keep in mind that only the original image file contain the embedded text. Once you send it through any digital form, it loses that information.

So you need a non-compressible image Format and checksums to verify file integrity. Doesn't sound too complicated
I'm always surprised that people never took advantage of the .PNG format. It allows for chunks of various data natively...
Yes PNG is nice, but still do not keep all data for a steganographied file.
Even if you attach it as file to an email or message is still compressing it so is altered and not containing anymore the stego data.
You must keep the original file you stego.
This is true
Fortunately, I should be able to keep the file size under 21MB so that I can upload it to nostr.build without transforming it
But you’re right, this is something to be aware of
