The algorithms you named have implementations in most major languages so there's no need for re-inventing the wheel which makes encrypting fairly easy. Just a matter of calling a few methods.
I know you're not looking into encryption here, im just saying other commercially available apps that do this do.

They don't just encrypt the data though, they shuffle it around and garble it. Otherwise it can be picked up with steganography scanners.

For a simple app though, converting it would be fine. Encryption isn't really needed for this use.

Though I personally would prefer to download a few massive files than a load of steg'd images.
