Convert HTML to Image with Node / Javascript

July 14th, 2021 / by api2pdf /


You might need to convert HTML to an image or HTML to png format for various reasons. Perhaps you are generating a snapshot or image preview of an HTML template you designed as part of your application. Maybe you are crawling websites and would like an image preview of all of them for a database. In either case, if you’re writing javascript and you have been doing research, you probably came across Headless Chrome or wkhtmltoimage. Working with either is a headache. Much easier to write just a few lines of code and call it a day. You can easily convert HTML to an Image (png) with nodejs / javascript within minutes using our REST API.

var a2pClient = new Api2Pdf('YOUR-API-KEY');

a2pClient.chromeHtmlToImage('Hello, World').then(function(result) { console.log(result); });

And that’s it! Modify the code as you see fit. Hopefully this saves you time and makes converting HTML to images easy and painless for those writing node / javascript code.
