Frequently Asked Questions
- What is Base64?
- Base64 is an encoding that turns binary or text into ASCII characters (A–Z, a–z, 0–9, +, /). Decoding converts it back to the original.
- What if decoding fails?
- Invalid or corrupted Base64 will show an error. Ensure the string is valid Base64 (no extra spaces unless you trim them first).
- Does it handle UTF-8 text?
- Yes. The tool uses decodeURIComponent(escape(atob(...))) or TextDecoder to support UTF-8 decoded text. Plain ASCII decodes directly.
