B64 – program that allows you to encode (decode) files in Base64 format.

The main features of the program B64:

• No installation required (Portable)
• High speed.
• The program is developed in 2 versions: 64 and 32-bit.
• Two operating modes
  1. Dialog:
  
  • Convenient and simple interface.
  • The interface language is Russian, but you can replace it with any one: prepare the text in the file XXX.lng (XXX is a 3-character language code) or default.lng. The file must be prepared in encoding UTF-8 with BOM.

  Call format:

  Encoding: b64.exe   [ /I ]   [ /W ]   input-file_1   [ output-file_1 ]

  Decoding: b64.exe   /D   input-file_2   [ output-file_2 ]

  input-file_1

  File path for encoding

  output-file_1

  The file path in BASE64 format.
  By default, an input file with the addition of .b64 (input-file_1.b64) is accepted.

  /I

  If the input file has the extension gif, jpg, jpeg, apng, png, ico, webp, tiff или bmp, then «DATA:URL» is added to the beginning of the output file
  data:image/x..x;base64,
  x..x is the input file extension.

  /W

  The output file is formed by lines of 76 characters. Lines end with "\ x0D \ x0A". "\x0D\x0A".

  input-file_2

  If the file has the b64 extension, you can omit the /D switch.

  output-file_2

  The path to the decoded file.
  By default, an input file without the .b64 extension or with the .dec extension is accepted.
