Welcome folks today in this tutorial we will be compressing jpg and png images using tinypng and tinyjpg api in node.js. All the full source code of the application will be shown below

Get Started

In order to get started you need to go to official website of tinypng to get free api key as shown here

And now after getting the api key you need to create a new node.js project in the empty directory and issue the below command

npm init -y

This will create the empty package.json file for your project

And now you need to install the tinify module of node.js as shown below

npm i tinify

After installing this library make an index.js file and copy paste the following code into it

app.py

const tinify = require("tinify");
tinify.key = "YOUR_API_KEY";
 
tinify.fromFile("unoptimized.png").toFile("optimized.png");

As you can see we are importing the library at the very first line of code and then we are setting the api_key of your project simply copy paste it from your dashboard and then we are taking the input image and compressing it

If you run your node.js project by typing the below command

node index.js

As you can see it has compressed a 1.89MB image to 368KB optimized and compressed image as shown below

You can also compress jpg images as well by node.js module just change or modify the above snippet of code like this as shown below

const tinify = require("tinify");
tinify.key = "###yourapi###key";
 
tinify.fromFile("profile.jpg").toFile("optimized.jpg");
