About the Base64 Converter
Use the Base64 Converter to encode readable UTF-8 text into Base64 or decode Base64 strings back into text. It is useful for inspecting payloads, test fixtures, simple tokens, config values, and encoded snippets while keeping the original and converted value side by side.
Common uses
- Encode short text for API payload examples or fixtures.
- Decode Base64 values from headers, logs, or config files.
- Check whether an encoded string is valid before using it elsewhere.
- Compare input and output lengths while debugging data transformations.
Browser workflow
- 01 Choose encode or decode mode.
- 02 Paste the text or Base64 string you want to inspect.
- 03 Copy the output or adjust the input when validation catches a problem.
