Perguntas Frequentes
What is the difference between standard and URL-Safe Base64?
Standard Base64 uses + and /, which can cause issues in URLs. URL-Safe Base64 replaces them with - and _ and omits padding.
Why do some Base64 decoders produce garbled characters with Unicode text?
Native browser atob only handles Latin1 characters. This tool utilizes TextEncoder/TextDecoder for proper UTF-8 handling.
