Base64 Encoder / Decoder
Convert strings to and from Base64 formatting instantly. Processed locally in your browser to secure raw payload data.
UTF-8 Safe Encoding
Base64 is a binary-to-text encoding scheme that translates binary data into a set of 64 printable characters. It is commonly used when raw byte sequences need to be transfered over mediums that only support standard text blocks (such as emails, JSON APIs, or HTML embeds).
Standard browser btoa and atob APIs crash on non-ASCII characters (such as emojis or accented characters). GeneratePass uses TextEncoder and TextDecoder buffers to convert Unicode strings safely without character corruption or parsing crashes.
What is the Base64 Encoder/Decoder?
The Base64 Encoder/Decoder converts text to and from Base64 format locally in your browser.
How it Works
It uses browser-native APIs combined with TextEncoder/TextDecoder buffers to support safe UTF-8 conversion.
Benefits of local generation
- Safe UTF-8 and emoji support.
- Completely offline conversion.
- Instant feedback.
Security Information
Converts text locally, ensuring your raw data is never exposed online.
Best Practices
- Use Base64 to encode binary data for text-only transports.
- Do not use Base64 for security or encryption.
- Check data padding if you get decoding errors.
