About this utility

How to use Base45, Base91 & Z85 Codec

Encode UTF-8 text into Base45, Base91, or ZeroMQ Z85 and decode valid text payloads locally.

What to provide

Choose the exact alphabet and direction. Z85 requires four input bytes per five encoded characters.

  1. Paste, type, or drag and drop a supported text file into the input area.
  2. Choose the options that match your intended result.
  3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

The encoded transport text or validated UTF-8 decoded value.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

  • Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. Decoding targets UTF-8 text. Use binary converters for arbitrary decoded bytes. Encoding does not provide encryption.
