Frequently Asked Questions
What is Base64 encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format using 64 unique characters.
Is Base64 encoding secure?
Base64 is NOT encryption. It is a way to represent data in a different format. Anyone can easily decode a Base64 string back to its original form.
Does this tool support emojis?
Yes, our encoder uses UTF-8 safe methods to ensure that emojis and special characters are preserved correctly during the encoding process.
What is the difference between encoding and decoding?
Encoding turns plain text into a Base64 string. Decoding takes that Base64 string and turns it back into readable plain text.
