How the Omni-Decoder Works
This free magic omni-decoder runs entirely in your browser; your data is never sent to any server. It automatically checks against common developer formats:
- Base64: Checks for valid A-Z, a-z, 0-9, +, / and padding characters.
- Hexadecimal: Detects contiguous blocks of 0-9 and A-F.
- URL Encoding: Looks for standard %20 style escaping.
- Binary: Validates streams of 0s and 1s.
- JWT: Identifies standard 3-part Base64Url separated by periods.
