About Base32 and Base58 Encoder

This Base32 decoder and encoder covers the Base formats that Base64 doesn't. Base32, as defined in RFC 4648, is used for the secret keys behind authenticator app codes, and Base32hex is its variant that keeps sort order. Base58 with the Bitcoin alphabet appears in wallet addresses and short IDs, because it leaves out look-alike characters such as 0, O, I and l. Ascii85 turns up inside PDF and PostScript files, Z85 comes from ZeroMQ, and Base16 is plain hex.

The input can be text or raw bytes written as hex, so a key or a hash can be encoded exactly as it is. Decoding gives the result back as text or as hex, whichever you need. For Base64 and URL-safe Base64, use the Base64 tool. Everything runs in your browser, and nothing is uploaded. A hash made with the Hash Generator can be pasted here as hex and encoded byte for byte.

FAQ

Base32 and Base58 Encoder: questions and answers

What is Base32 encoding used for?
Mostly for secrets people type or scan, such as the keys behind authenticator app codes (TOTP), because it uses only capital letters and the digits 2 to 7.
What's the difference between Base58 and Base64?
Base58 drops 0, O, I, l, + and /, so the result has no look-alike characters or symbols, which suits Bitcoin addresses and IDs people copy by hand. Base64 is a little more compact.
Can I decode a Bitcoin address to hex?
Yes. Choose Base58, decode, and ask for hex output to see the raw bytes, including the version byte at the start and the checksum at the end.
How are Ascii85 and Z85 different?
Both turn 4 bytes into 5 characters. Ascii85 is the Adobe version used in PDF and PostScript, while Z85 uses a character set that can go inside strings in source code without escaping.
Where do I encode or decode Base64 instead?
In its own tool, Base64 Encode and Decode, which handles text and files and has a URL-safe option.
