Decode Base85 text back into readable UTF-8 output.
Use this Base85 decoder to convert ASCII85-compatible input back into plain text. It is useful for debugging compact encoded payloads, reversing encoded strings, and working with developer data formats that use Base85.

Input

Output
Hello world
Decodes ASCII85-style input back into readable text.
Fix: Check that the source is really Base85 and was copied fully.
Fix: Check whether the source data is text-based or arbitrary binary content.
Fix: Use Base85 Encode when the source is plain text.
Yes. It can handle common ASCII85-style input and ignores optional wrapper markers like <~ and ~>.
Yes. It supports the common ASCII85 z shorthand for four zero bytes.
It is useful for reversing compact payloads, debugging encoded data, and checking ASCII85-compatible strings.
Yes. It works online in the browser.
Use Base85 Decode when the input is ASCII85-compatible Base85 text. Use Base64 Decode when the source belongs to the Base64 family.
