4 Ways To Convert HTML To Image In PHP

Welcome to a tutorial on how to convert HTML to an image in PHP. So you have a PHP project that needs to convert HTML into an image? Bad news, there are no free “HTML to image” libraries at the time of writing.

  • Use the browser headless mode to open a URL and capture a screenshot.
  • Open the HTML in a browser, capture a screenshot, then send it to PHP for processing.
  • Use an online conversion service.
  • Convert HTML to PDF first, then save the PDF as an image.

It’s kind of roundabout, but possible – Read on for the examples!

TABLE OF CONTENTS

DOWNLOAD & NOTES

Here is the download link to the example code, so you don’t have to copy-paste everything.

EXAMPLE CODE DOWNLOAD

Just click on “download zip” or do a git clone. I have released it under the MIT license, so feel free to build on top of it or use it in your own project.

SUPPORT

600+ free tutorials & projects on Code Boxx and still growing. I insist on not turning Code Boxx into a «paid scripts and courses» business, so every little bit of support helps.

PHP HTML TO IMAGE

All right, let us now get into the possible ways of converting HTML into an image in PHP.

TUTORIAL VIDEO

1) HEADLESS MODE SCREENSHOT

// (A) SETTINGS $chrome = "C:\Program Files\Google\Chrome\Application\chrome.exe"; // path to chrome $saveas = __DIR__ . DIRECTORY_SEPARATOR . "demoA.png"; // save screenshot $size = "1080,1920"; // height, width $url = "https://code-boxx.com"; // url to access // (B) HEADLESS CHROME $cmd =
  • This snippet simply runs chrome --headless --screenshot="demoA.png" --window-size=1080,1920 "https://code-boxx.com" in the command line.
  • “Headless mode” will open the browser but does not show it on the screen.
  • That is, silently open https://code-boxx.com and take a screenshot.

For those who are lost – Create your own HTML file, for example, http://localhost/foo.html . Use headless mode to access that HTML file and take a screenshot, that’s your “HTML to image” conversion.

P.S. Both Opera and Edge are also Chromium-based, capable of running in headless mode. Firefox can also run in headless mode. Not too sure about the half-eaten apple.

2) BROWSER SCREENSHOT

2A) HTML & JAVASCRIPT

 
TEST PAGE
 
Hello world!
  • (B1) We are using HTML2Canvas to capture a screenshot
  • (B2) Upload the screenshot to the server.

P.S. You can create a bat (Windows) or sh (Linux/Mac) to open a web browser. For example, chrome.exe --app=http://localhost/2a-page.php . Then, set it to run on schedule, or use PHP exec() to call it on demand.

2B) PHP

In this example, we simply save the uploaded screenshot to a PNG file. In your project, you can pretty much do whatever you want – Save into a database, save into a cloud drive, send via email, etc…

3) ONLINE HTML TO IMAGE SERVICE

TEST PAGE 
Hello world!
 HTML; // (A2) CSS $css = p < color: red; >CSS; // (B) USE API TO CREATE PNG // (B1) CURL INIT $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://hcti.io/v1/image"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([ "html" => $html, "css" => $css ])); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_USERPWD, "user_id" . ":" . "api_key"); // CHANGE TO YOUR OWN! curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: application/x-www-form-urlencoded"]); // (B2) CURL EXEC $result = curl_exec($ch); if (curl_errno($ch)) < echo curl_error($ch); >curl_close($ch); $result = json_decode($result, true); // (C) FETCH & SAVE PNG $fh = fopen("demoC.png", "w"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $result["url"]); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FILE, $fh); curl_exec($ch); curl_close($ch); fclose($fh); echo "OK";

Nobody has released a free PHP HTML to image library, but there are plenty of such conversion services online. A free one that I found is HCTI.

  • (A & B) Create your HTML/CSS as usual.
  • (B) Send the HTML/CSS to HCTI, create a PNG image.
  • (C) Fetch the generated image, do whatever is required – We simply save it in this example.

P.S. Remember to sign up for a free account and change the user/password to your own in (B1).

4) HTML TO PDF, PDF TO IMAGE

// (A) HTML CONTENT $html = TEST PAGE 
Hello world!
 HTML; // (B) HTML TO PDF require "vendor/autoload.php"; $mpdf = new \Mpdf\Mpdf(); $mpdf->WriteHTML($html); $mpdf->Output("demoD.pdf"); // (C) PDF TO IMAGE $image = new Imagick("demoD.pdf"); $image->setImageFormat("jpg"); $image->writeImage("demoD.jpg");
  • MPDF – The easiest way is to use Composer composer require mpdf/mpdf .
  • ImageMagick – The installation is kind of confusing, and cannot be explained in a paragraph… You will need to do some research on your own.

But yep, this is pretty much “HTML to PDF”, then “PDF to image”.

EXTRAS

That’s all for the tutorial, and here is a small section on some extras and links that may be useful to you.

WHICH IS THE BEST METHOD?

  • Browser Screenshot (headless or not) – I am personally leaning towards this method, simply because it’s the most accurate and free.
  • Online Service – Works if you are running a command line PHP, but probably need to pay if you need to process many of such images.
  • HTML to PDF to image – Works as well, but inefficient.

PHP: HTML/CSS to Image

For more details on how this works, see Creating an image.

Example API response:

Image generated with PHP. Convert HTML to an image using PHP.

Authentication with PHP

Your username is your User ID and your password is your API Key. Both of these are available from the dashboard. The PHP code sample demonstrates how to authenticate your request.

You can signup for a free API key to get started.

PHP example code

This PHP code example sends an HTTP POST to the https://hcti.io/v1/image API. Converting your HTML/CSS to an image with PHP.

 Generated from PHP ✅
EOD; $css = EOD; $google_fonts = "Roboto"; $data = array('html'=>$html, 'css'=>$css, 'google_fonts'=>$google_fonts); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://hcti.io/v1/image"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_POST, 1); // Retrieve your user_id and api_key from https://htmlcsstoimage.com/dashboard curl_setopt($ch, CURLOPT_USERPWD, "user_id" . ":" . "api_key"); $headers = array(); $headers[] = "Content-Type: application/x-www-form-urlencoded"; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $result = curl_exec($ch); if (curl_errno($ch)) < echo 'Error:' . curl_error($ch); >curl_close ($ch); $res = json_decode($result,true); echo $res['url']; // https://hcti.io/v1/image/202dc04d-5efc-482e-8f92-bb51612c84cf ?>

PHP example with Guzzle library

Using an HTTP library such as Guzzle can simplify your code even further. Here’s an example of how to use the HTML/CSS to Image API with Guzzle.

Installation instructions for Guzzle are here.

Pong ✅
"; $css = ".ping < padding: 20px; font-family: 'sans-serif'; >"; $client = new GuzzleHttpClient(); // Retrieve your user_id and api_key from https://htmlcsstoimage.com/dashboard $res = $client->request('POST', 'https://hcti.io/v1/image', [ 'auth' => ['user_id', 'api_key'], 'form_params' => ['html' => $html, 'css' => $css] ]); echo $res->getBody(); // ?>

The code turns out to be a bit more readable and less complex when using Guzzle. A great option if you’re open to adding the library to your project.

Debugging Error:SSL certificate problem: unable to get local issuer certificate

When running this script on a Windows machine, it’s possible you’ll get an SSL error. The fix for this is here.
