Frequently Asked Questions (FAQ)
Is Base64 encoding secure?
No, Base64 is an encoding scheme, not encryption. It can be easily decoded by anyone. It should never be used to secure sensitive data like passwords.
Why use Base64?
Base64 is used to represent binary data in an ASCII string format. This is essential for transmitting data over protocols that only support text, like email or certain API formats.
Does it support UTF-8 characters?
Our converter handles standard UTF-8 characters. For binary files or complex character sets, ensure the input is properly stringified before encoding.
Is my data sent to your server?
No. All encoding and decoding happens locally in your browser. We respect your privacy and never transmit your input data.
What is the character set used in Base64?
Base64 uses 64 characters: A-Z, a-z, 0-9, +, and /. The = character is used as padding at the end of the encoded string.
