Frequently Asked Questions
What is Base64 encoding used for?
Base64 is a way of representing binary data as printable ASCII text. It's commonly used to embed images in emails or HTML, or when sending data through channels that only support text.
Is Base64 a form of encryption?
No, Base64 is NOT encryption. It is a simple encoding scheme that can be easily reversed by anyone. Do not use it for sensitive information without additional security.
What does the 'URL safe' option do?
Standard Base64 uses characters like '+' and '/', which can cause issues in web URLs. The 'URL-safe' mode replaces these with '-' and '_' to make the string safe for use in links.
