About Base32 Decoder
Base32 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. It uses a smaller set of characters than Base64, usually the uppercase alphabet and the numbers 2 to 7.
Input: text. Output: binary bytes.
Format reference: From Base32 background and specification
Example

Parameters
| Parameter | Default value | Input and choices |

| Remove non-alphabet chars | true | On or off |
Before interpreting the result
Choose a decoder for an encoded payload, an encoder for transport, or a converter for structured data. Hex and Base64 represent bytes; converting formats does not encrypt or authenticate them.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
