Base32 Encoder/Decoder
Encode plain text to Base32 strings or decode Base32 data back to readable text online.
Run tool
This online Base32 Encoder and Decoder converts plain text into standard Base32 encoded strings and decodes Base32 character sequences back into readable text. Base32 represents binary data using a 32-character set consisting of uppercase letters A through Z and digits 2 through 7. This encoding format is frequently used in two-factor authentication secret keys, domain name systems, legacy network protocols, and environments where case-insensitive transmission avoids transcription errors. To use the tool, paste your text into the input field and select either the encode or decode mode. The tool defaults to encoding plain text into Base32. If you need to recover the original message from a Base32 string, choose the decode option. Both operations process non-empty text strings cleanly and display the converted string directly in the output area. Entering empty text or providing an invalid character sequence when decoding produces an error notice so you can adjust your input.
Instructions
- Enter or paste your text into the Text field.
- Select Encode to convert plain text into Base32, or select Decode to restore original text from Base32.
- Click the run button to convert the text.
- Copy the converted string directly from the result panel.
Examples
- Encoding the text string "Hello World" produces the Base32 output "JBSWY3DPEBLW64TMMQ======".
- Decoding the Base32 string "JBSWY3DPEBLW64TMMQ======" returns the original plain text "Hello World".
FAQ
What character set does Base32 use?
Base32 uses the uppercase English letters A through Z and the numerals 2 through 7, with padding characters as needed.
What happens if I submit an empty text field?
The tool requires non-empty text input. Submitting an empty field displays an error indicating that valid input is needed.
Why is Base32 used instead of Base64?
Base32 is case-insensitive and omits visually ambiguous characters like 0, 1, 8, and O, making it ideal for spoken communication and systems where case sensitivity is not preserved.
