Frequently asked questions
What is Base64?
Base64 is an encoding scheme that represents binary data as ASCII text using 64 characters. Widely used in JWTs, emails, and data URLs.
Is Base64 a form of encryption?
No. Base64 is just encoding, not encryption. Anyone with the Base64 text can decode it easily.
Why does my decoding fail?
Base64 text must only contain A-Z, a-z, 0-9, +, / and = (padding). Any other character will cause an error.
