Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used to transmit data over text-based protocols, embed images in CSS/HTML, and encode JWT payloads.
What is URL-safe Base64?
URL-safe Base64 replaces + with - and / with _ to make the encoded string safe to use in URLs without percent-encoding. It also omits padding = characters.
Does Base64 encrypt my data?
No. Base64 is encoding, not encryption. Encoded data can be trivially decoded by anyone. Never use Base64 as a security measure—use proper encryption instead.
