What does this Base64 tool do?
This tool converts plain text into standard Base64 or URL-safe Base64 and can decode Base64 back into readable UTF-8 text. It is useful when you need to inspect encoded payloads, work with tokens, or prepare strings for transport.
How to use the Base64 encoder and decoder
- Paste plain text if you want to encode it, or paste Base64 if you want to decode it.
- Choose Encode text, Encode URL-safe, or Decode Base64.
- Review the output, then copy it for your next step.
Common use cases
- Inspect Base64 values copied from APIs, tokens, or configuration files.
- Create URL-safe Base64 strings for query parameters or lightweight sharing.
- Convert Unicode text safely instead of relying on ASCII-only encoders.
