Text is generally stored in a computer system with a bit depth of 2 7 or 128 possible values per position. What's up with that? Yes, base64 encoded text is longer than the unencoded text it represents. If you need help sleeping, you can read section 6.8 of IETF RFC 2045 which is the official definition of the specification.īut my text got longer when I encoded it. Base64-encoded data could also represent images or other binary data types. This site will help you decode text that was encoded with Base64 to protect special characters or whitespace within the text. A 65th character, "=" is used to pad the content to a multiple of 24 bits in length. The last two characters may differ between encodings the MIME specification uses "+" and "/" to complete the sequence.
Most Base64 encoding schemes use A–Z, a–z, and 0–9 for the first 62 characters. 64 refers to the 64 characters that are used to represent the encoded data. The name Base64 comes from the MIME content-transfer-encoding that uses this scheme. "Base64" can refer to a variety of encoding types that take binary data and convert it to text for safe transport over systems like email that do not guarantee safe transit of binary data. Text to convert: Direction Encode to base64ĭecode from base64 Result: About Base64 Encoding Need to decrypt that garbled text string you got in an email? Or data encoded in a configuration file? Concerned about the security of that data? My base64 encoder/decoder process the request in your browser with javascript, so your data doesn't touch my server.
