How to use Base64 Encoder/Decoder
Typical uses
- Encode a short text snippet for a data field.
- Decode a Base64 sample during debugging.
- Check whether a Base64 value contains readable UTF-8 text.
Tips
- Base64 is an encoding format, not encryption.
- Do not paste secrets into browser tools unless you are comfortable with the page context.
Base64 is not encryption. Anyone with the encoded value can decode it back to the original text if it represents readable data.
