FAQ
What's the difference between Base64 and Base85?
Base64 converts 3 bytes into 4 characters (75% efficiency), while Base85 converts 4 bytes into 5 characters (80% efficiency), representing binary data more compactly.
Why does a "z" character sometimes appear?
The Adobe variant of Ascii85 has a special rule: a 4-byte group that's entirely zero is shortened to a single "z" character.
Where is this used?
It's commonly used to embed binary data (like images) as text inside PostScript and PDF files.
