Base64 & URL encoder
Encode and decode Base64, URL-safe Base64 and percent-encoded URLs, with full Unicode support.
How it works
Base64URL swaps + and / for - and _, and drops the padding, so it’s safe in URLs and JWTs. URL encoding escapes characters that have meaning in URLs.
Questions
Is Base64 encryption?
