For my recent project, i will have to deal with plenty of images. With a view to making server respond faster, I decided to save images in the form of binary numbers. Is there any way I could create a binary converter with the help of math algorithm?

Are you talking about image formats here? For binary, do you mean bitmap?

I don't know about bitmap but I'm going to research on that. But, I have read that Mongodb uses binary numbering system to save images with a view to make it faster. Since, binary contains zeros and ones, it occupies lesser memory and improves page loading speed.

Actually, i just found a node.js package for the same conversion: https://www.npmjs.com/package/b2tconverter and the website, https://binarytotext.net

i have gone through the working, this is the code i found for image to binary conversion:

var file = inputElement.files[0];

var reader = new FileReader();

reader.onloadend = function() {

console.log('Encoded Base 64 File String:', reader.result);

/******************* for Binary ***********************/

var data=(reader.result).split(',')[1];

var binaryBlob = atob(data);

console.log('Encoded Binary File String:', binaryBlob);

}

reader.readAsDataURL(file);

Once, I will get the binary conversion, I will save binary into database. I'm going to implement this tomorrow and I'm optimistic that will find the solution.
