Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data to a text format using 64 characters (A-Z, a-z, 0-9, +, /). It's commonly used to transmit data over text-based protocols.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption. It is easily reversible and provides no security. Do not use it to hide sensitive data.
When is Base64 encoding used?
Common uses include embedding images in CSS/HTML (data URIs), encoding binary data in JSON APIs, storing complex strings in URLs, and email attachments (MIME).
