How it works
The decoder accepts standard (+ /) and URL-safe (- _) alphabets, ignores spaces and line breaks, and adds missing “=” padding. The bytes are then read as UTF-8 text. If they aren't valid text (an image or a file encoded in Base64), the tool tells you — use the Base64 File Decoder to get the file back.
