Base85 Encode / Decode
Base85 packs four bytes into five characters, making it more compact than Base64. This tool supports common variants such as Ascii85 and the IPv6 RFC 1924 form.
Key Features
- Ascii85 and RFC 1924 variants
- Binary, text or hex input
- Configurable delimiter
- Decode back
- Fully local
Use Cases
- Embed binary in PostScript or PDF
- Encode an IPv6 address compactly
- Shrink data for transport
- Compare encoding efficiency
How to Use
- Choose the variant
- Paste the input
- Convert
- Copy the output
Practical Tips
- Ascii85 often wraps output in <~ ~>
- It is denser than Base64 but less universal
- Watch for variant-specific delimiters
FAQ
- When use Base85?
- When you need denser encoding than Base64 in a compatible system.
- Is it safe?
- It is encoding, not encryption; data is not secret.
