Frequently Asked Questions
What is ASCII85 (Base85)?
ASCII85 is a form of binary-to-text encoding. By using 85 different ASCII characters, it is more efficient than Base64, representing 4 bytes of data with only 5 characters.
Why use ASCII85 over Base64?
ASCII85 results in a smaller encoded size compared to Base64 (about 25% overhead vs 33% for Base64). It is widely used in PostScript and PDF files for this reason.
What are the '<~' and '~>' markers?
These are traditional Adobe delimiters used to signify the start and end of an ASCII85-encoded data stream, helping parsers identify where the encoding begins and ends.
