This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

Base Decoder converts data between formats in your browser. For a correct result, set the correct radix.

the value decoded from base 10 Processing runs in the browser.

Instructions

  1. Provide text or data for this tool.
  2. Select the source base and output format.
  3. Compare the output with a known Base Decoder sample.
  4. Keep the original value until the receiving system accepts the result.

Example

Input: 1010

Settings: Base Decoder: select the source base and output format

Result: the value decoded from base 10

Limits

  • Base Decoder: a wrong radix gives a different value
  • Base Decoder: The operation does not detect a different input format automatically.
  • Base Decoder: Processing stays in the browser.

Questions

How do I convert a base-36 number to decimal?

Enter the number and set Radix to 36. The decoder treats the input as one number and returns its decimal value. Use a byte decoder when the input represents separate encoded characters or bytes.

Which numerical bases can this decoder read?

The Radix setting supports values from 2 through 36. Select the base that defines the input digits. Letters can represent higher digit values, so a string can have different numeric meanings under different bases.

Does base conversion preserve leading zeros?

Numeric conversion preserves a value, not its original written width. Leading zeros can disappear from the result. Keep a separate width specification when the input is an identifier, fixed-width field, or binary record.
