Frequently asked questions
- Does Base64 encrypt data?
- No. Base64 is encoding, not encryption. Anyone can decode Base64 strings.
- Does this support Unicode and emoji?
- Yes. Text is encoded and decoded as UTF-8, so most international characters are supported.
- Is my input stored?
- No. Encoding and decoding run locally in your browser.
- Can I decode URL-safe Base64?
- This tool expects standard Base64. Replace URL-safe characters (- and _) with + and / before decoding if needed.
