What This Tool Does
This browser-based Base64 text tool converts plain text into Base64 strings and decodes valid Base64 back into readable Unicode text without sending content to the backend.

Base64 Text Encoder and Decoder
Encode text to Base64 or decode Base64 back to Unicode text directly in your browser.
Base64 represents bytes; it does not protect text
Use Base64 when a format expects text-safe bytes, then decode it only in an authorized context.
- This tool encodes Unicode text as UTF-8 Base64 and decodes valid Base64 back to UTF-8 text.
- Anyone who has the Base64 value can usually decode it; it is neither encryption nor a password or integrity check.
- Keep padding and the exact original value when another system expects standard Base64.
Conversion, copying, and text download run locally in the browser. Do not use an encoded value as a substitute for protecting a secret.
Understand Base64, URL Encoding, and HTML Entities Without Treating Them as EncryptionBase64 Text Encoder and Decoder
Encode text to Base64 or decode Base64 back to Unicode text locally in your browser for configuration, API testing, and log inspection.
Common Use Cases
- Encoding text to Base64 for configuration values, scripts, or API tests
- Decoding Base64 text from logs, API responses, or config values
- Checking Base64 encode and decode output for Unicode text
How Data Is Handled
Text Base64 conversion runs in your browser. The text is not uploaded to the server.
FAQ
Is Base64 encryption?
