Frequently Asked Questions
What is Base64 encoding?
Base64 is a way of representing binary or text data using 64 printable ASCII characters. It is commonly used to embed images in HTML/CSS, send data in URLs, and store data in JSON or XML safely.
Is this Base64 tool Unicode-safe?
Yes. It encodes and decodes using UTF-8, so emojis and non-English characters (Bengali, Arabic, Chinese, etc.) are handled correctly.
Is my data private?
Yes. Encoding and decoding run entirely in your browser. Nothing you type is ever sent to a server.
Why does Base64 end with = signs?
The = characters are padding. Base64 works in blocks of three bytes, so when the input length is not a multiple of three, one or two = are added to fill the last block.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption — anyone can decode it. Use it to safely transport data, not to keep it secret. For secrecy, use real encryption.
