Frequently Asked Questions
What is Base64 used for?
Base64 is commonly used to embed images directly into web pages (Data URLs), send attachments in emails (MIME), and transmit binary data over text-based protocols like JSON or XML.
Is it safe to decode unknown Base64 strings?
While decoding itself is safe, be cautious when decoding and running executable files or opening unknown documents from untrusted sources.
Does Base64 encryption secure my data?
No, Base64 is NOT encryption. It is an encoding scheme. Anyone can decode Base64 data if they have access to it. Do not use it for sensitive data without proper encryption.
