VGhlIGJhc2tldCBpcyBmdWxsIG9mIGdyYXBlcy4= Image to base64 encoding example The text input is first encoded as binary bit stream of ASCII codesĮach 6 bits of the bit stream are encoded to base64 digit. The result will be QUJD REVG R0g= (without spaces).URL decoder ► Text to base64 encoding example Similarly, it will add one = at the end of the output to get 4 characters. Thus, the result will be QUJD REVG Rw= (without spaces). But for the third, it will add a double = in the output in order to complete the 4 needed characters. You will not have an = sign if your string has a multiple of 3 characters, because Base64 encoding takes each three bytes (a character=1 byte) and represents them as four printable characters in the ASCII standard.īase64 deals with the first block (producing 4 characters) and the second (as they are complete). The last character ( = sign) is added only as a complement (padding) in the final process of encoding a message with a special number of characters. (the word usb is base64 encoded into dXNi) Q Does a base64 string always end with =?Ī: No.
