How to use it
Paste your text and pick Encode to get Base64, or paste Base64 and pick Decode to get the original text back. Handy for data URLs, API tokens, email attachments and config files. Unicode (UTF-8) is handled correctly.
Example
Input
hello → (Encode) Result
aGVsbG8= Frequently asked questions
Is Base64 encryption?
No. Base64 is encoding, not encryption — it only changes the representation, not the security. Anyone can decode it, so never use it to protect passwords or secrets.
Does it support special characters and emoji?
Yes. Text is treated as UTF-8, so accents, Cyrillic, emoji and any Unicode round-trip correctly.
Is my text sent anywhere?
No. Encoding and decoding happen entirely in your browser; nothing is uploaded.
