Instructions for use
Select encoding or decoding and Base64 format, enter the content and click Convert. URL-safe format uses minus signs and underscores, and omits trailing padding when encoding; legal padding is automatically filled in when decoding. The tool only accepts text that can be reverted to UTF-8.
Good for converting configuration snippets, API parameters, and short text. Base64 is only an encoding method and does not provide encryption or privacy protection; do not treat the encoding result as ciphertext.
