Questions
Is Base64 a form of encryption?
No. Base64 is an encoding that anyone can reverse. Do not use it to hide passwords or private data.
What is URL safe Base64?
It replaces + with - and / with _ and usually drops the = padding, so the result can sit in a URL or file name without extra escaping. It is also called base64url.
Why is the Base64 bigger than my file?
Base64 turns every 3 bytes into 4 characters, so the output is about a third larger than the input.
