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.
