HTML to an in-memory image buffer with PHP and Puppeteer

Heads up before you start

Puppeteer has no official PHP port. The closest equivalent is chrome-php — an actively maintained PHP library that controls headless Chrome over the same DevTools Protocol Puppeteer uses. These examples use chrome-php.

Install chrome-php

composer require chrome-php/chrome

chrome-php drives a Chrome or Chromium you already have installed — it does not download its own browser. It uses the CHROME_PATH environment variable if set, and otherwise looks in the standard install locations for your OS.

Get the image as an in-memory buffer

<?php
require __DIR__ . '/vendor/autoload.php';

use HeadlessChromium\BrowserFactory;

$browser = (new BrowserFactory())->createBrowser();

$page = $browser->createPage();
$page->setHtml('<html><body><h1>Hello World</h1></body></html>');

$image = $page->screenshot()->getRawBinary(); // binary string, not written to disk
printf("got %d bytes\n", strlen($image));

$browser->close();

That was 14 lines of code — plus a browser to run in production

Keeping headless browsers fed, patched and scaled is a job in itself. We built Urlbox so the same screenshot is one API call:
