How to Use Base85 Encoder/Decoder

What is Base85 Encoder/Decoder?

The Base85 (Ascii85) Encoder/Decoder converts binary data to and from Base85 encoding, which achieves approximately 25% better space efficiency than Base64 by encoding 4 bytes into 5 ASCII characters. Ascii85 was developed by Adobe for use in PostScript and PDF internal data streams — it is specified in the PDF standard (ISO 32000) as the ASCII85Decode filter. The ZeroMQ messaging library uses a variant called Z85 for encoding binary message frames in text protocols.

Features

How do I use Base85 Encoder/Decoder?

Enter text or paste binary content (hex-encoded) into the input field and click Encode to produce Ascii85 output, or paste an Ascii85-encoded string and click Decode to recover the original bytes. The tool handles standard Ascii85 delimiters automatically and supports both the Adobe variant and Z85 variant used by ZeroMQ.
