Introduction base encoding of data is used in many situations to store or transfer data in environments that, perhaps for legacy reasons, are restricted to only usascii data. In addition, you will receive some basic information about this video file duration, resolution, mime type, extension, size. To get the fastest decoding, it is recommended to use the pybase64. For base 64, the nonalphanumeric characters in particular may be problematic in file names and urls. It also contains several articles on how to perform base64 decoding in different programming languages. Hex to base64 base64 encode base64 converter base64. The base64, base32, and base16 encodings convert 8 bit bytes to values with 6, 5, or 4 bits of useful data per byte, allowing nonascii bytes to be encoded as ascii characters for transmission over protocols that require plain ascii, such as smtp. The string encode method returns encoded version of the given string.
