Base85 / Ascii85 Converter

What is a Base85 / Ascii85 Converter?

Encode and decode text or binary data using Base85 / Ascii85 algorithms (including Adobe PostScript/PDF Ascii85 and ZeroMQ Z85 variants).

Why Use This Converter?

  • PostScript & PDF Processing: Decode binary streams embedded inside Adobe PDF files and PostScript graphics.
  • ZeroMQ Networking: Format binary keys and messages for ZeroMQ (Z85) socket communication.
  • High-Density Encoding: Achieves 25% overhead compared to Base64 33% overhead.

How to Use

  1. Choose Variant (Adobe Ascii85 or ZeroMQ Z85).
  2. Select Encode or Decode mode.
  3. Paste your data and copy the converted result.
