Encode and decode Base64
Base64 turns text or data into a small set of safe characters that survive systems built only for plain text. Encode turns your text into Base64, and decode turns Base64 back into the original. This tool handles full Unicode, so emoji and non-Latin scripts make the round trip without breaking.
How to use the Base64 tool
Paste text to encode or a Base64 string to decode, click the matching button, and copy the result.
Frequently asked questions
Why do I get an error when decoding?
The input is not valid Base64. Check for missing characters, stray spaces or line breaks that crept in during copying.
Is Base64 a form of encryption?
No. Base64 is encoding, not encryption. Anyone can decode it, so it provides no security or secrecy.
