How To Covert Base64 Encoded Image To A Tiff/png/jpeg Using Nodejs

I have a image that is in base64 string that I would like to convert to a graphic format such as TIFF, BMP, or JPG. base64string = 'data:image/gif;base64,R0lGODlhPQBEAPeoAJosM//AwO

Solution 1:

I got solution for this by using sharp npm module we can do this

• npm install sharp --save

  const sharp = require('sharp');
  
  var img_src = base64_string;            
  const base64Data = newBuffer(img_src.replace(/^data:image\/\w+;base64,/, ""), 'base64')
  
      sharp(base64Data)
      .tiff({
          compression: 'lzw',
          squash: true
       })
      .background('white')
      .embed()
      .toBuffer()
      .then(data_img => {
          //  tiff image data
       });
