You can't just save an image in different sizes by writing part of the file to disk. In order to resize your image you need to first know what image format you are working with and then use an appropriate library to resize the image, usually by reducing image quality or cropping the image.

For example if you are working with a JPEG, PNG, WebP, or TIFF images, you could use https://github.com/lovell/sharp

From its example page const sharp = require('sharp'); sharp(inputBuffer) .resize(320, 240) .toFile('output.webp', (err, info) => ... );

I will use JPG and PNG. In input buffer I create my buffer previously like this ? var inputBuffer = new Buffer(base4String). And 'output.webp' is the path where the image will be ?
