Frequently asked questions
Is Base64 a form of encryption?
No. Base64 only changes how data is written. Anyone can decode it, so never use it to hide passwords or secrets.
What is URL-safe Base64?
A variant that uses - and _ instead of + and / and leaves out the = padding, so the result can be used in a URL without escaping.
Why does decoding fail?
The input has characters that are not Base64, is cut off, or contains binary data such as an image rather than text.
