baseMEOW is an encoder/decoder that can store binary as a string of characters that spell out "meow" in some way, similar to base64.
# requires Python 3.7+
pip install baseMEOW$ echo 'hello' | baseMEOW
MeEeeOoWmEeooWwmmEeowwwWw
$ echo 'im a kitty' | baseMEOW
MeEeOwWMeeEEEoOOwwWWWmMmeOoOwMEooWMeeOWwMMMmM
$ dd if=/dev/urandom bs=1 count=30 | baseMEOW
30+0 records in

|---|---|---|---|---|
| 10 characters | 11.06 | 202.69 | 17 | 42 |

Using the assembly encoder the runtimes are much better.
