Latest and greatest way to do this  Node supports file and buffer operations with the base64 encoding  const fs   require  fs    const contents   fs readFileSync   path to file jpg    encoding   base64      Or using the new promises API  const fs   require  fs   promises  const contents   await fs readFile   path to file jpg    encoding   base64

I think that the following example demonstrates what you need http   www hacksparrow com base64-encoding-decoding-in-node-js html  The essence of the article is this code part   var fs   require  fs        function to encode file data to base64 encoded string function base64 encode file           read binary data     var bitmap   fs readFileSync file          convert binary data to base64 encoded string     return new Buffer bitmap  toString  base64          function to create file from base64 encoded string function base64 decode base64str  file           create buffer object from base64 encoded string  it is important to tell the constructor that the string is base64 encoded     var bitmap   new Buffer base64str   base64           write buffer to file     fs writeFileSync file  bitmap       console log           File created from base64 encoded string                   convert image to base64 encoded string var base64str   base64 encode  kitten jpg    console log base64str      convert base64 string back to image  base64 decode base64str   copy jpg
