Use a real headless Chrome or Chromium browser when your PHP code must turn HTML and CSS into an image. A browser handles modern CSS, web fonts, JavaScript, lazy-loaded images, and responsive layouts. In PHP, the most practical routes are Spatie Browsershot (PHP controlling Puppeteer), the chrome-php/chrome library (PHP controlling Chrome directly), or a hosted rendering API when you do not want to install and operate a browser.
This guide shows runnable local PHP examples, explains when a hosted service is safer operationally, separates raster images from PDF workflows, and covers sizing, assets, security, reliability, and common failures.
Choose the rendering path first
The correct implementation depends on what “HTML to image” means for your project.
| Path | Rendering location | Best fit | Main trade-off |
|---|---|---|---|
| Spatie Browsershot | Local Chrome/Chromium through Puppeteer | Applications already using Node tooling or needing full browser behavior | PHP, Node.js, Puppeteer, and a compatible browser must be deployed together |
| chrome-php/chrome | Local Chrome/Chromium controlled directly from PHP | PHP-first services that need viewport, clipping, JavaScript, and image output | Chrome/Chromium remains a system dependency; verify compatibility with your runtime |
| Hosted HTML/CSS rendering API | Vendor-managed Google Chrome | Teams that prefer an HTTP request over browser operations | Credentials, network dependency, vendor limits, and sending HTML/assets outside your infrastructure |
| Dompdf or mPDF | PHP PDF renderer | PDF documents, not browser screenshots | Do not expect a direct PNG/JPEG/WebP screenshot equivalent |
For a screenshot of a JavaScript-heavy page, a local or hosted Chromium renderer is the dependable choice. For a static document whose required output is PDF, use a PDF library instead of forcing a raster workflow.

Option 1: PHP with Spatie Browsershot
Browsershot controls headless Google Chrome through Puppeteer. Its documented workflow can render a URL, an HTML string, or a local HTML file and save an image or PDF. Installation therefore includes PHP packages plus Node.js, Puppeteer, and a browser binary.
Install and verify prerequisites
- Install the Browsershot Composer package in your application.
- Install Node.js and Puppeteer as required by the Browsershot version you selected.
- Make sure the PHP worker user can execute Node and Chrome and can write to the destination directory.
- Run a small capture from the same service account used in production; a browser that works in your shell may fail under PHP-FPM because of PATH, permissions, or sandbox settings.
Render a URL to WebP
<?php
require __DIR__ . '/vendor/autoload.php';
use SpatieBrowsershotBrowsershot;
Browsershot::url('https://example.com')
->windowSize(1200, 800)
->deviceScaleFactor(2)
->waitUntilNetworkIdle()
->save('storage/app/example.webp');The destination extension determines the image format in common Browsershot usage. Use a writable absolute path in workers and containers, and create the directory before capture.
Render an HTML string
<?php
require __DIR__ . '/vendor/autoload.php';
use SpatieBrowsershotBrowsershot;
$html = '<!doctype html>
<html><head>
<meta charset="utf-8">
<style>
body { margin: 0; font-family: Arial, sans-serif; }
.card { width: 1200px; padding: 64px; background: #111827; color: white; }
</style>
</head><body>
<section class="card"><h1>Release 2.4</h1><p>Generated by PHP</p></section>
</body></html>';
Browsershot::html($html)
->windowSize(1328, 800)
->setScreenshotType('webp')
->save('storage/app/release-card.webp');For external fonts, images, or stylesheets, use absolute HTTPS URLs or a correctly configured base URL. A relative path that works in a browser tab may not resolve when the HTML is supplied directly as a string.
Capture only one element
Give the target an unambiguous CSS selector and use Browsershot’s selector/clipping capability. This avoids producing a full-page image when the required asset is a card, chart, or invoice panel. Keep the element’s width deterministic; auto-sized content can produce different dimensions as text or fonts load.

Minimal URL screenshot
<?php
require __DIR__ . '/vendor/autoload.php';
use HeadlessChromiumBrowserFactory;
$factory = new BrowserFactory();
$browser = $factory->createBrowser([
'headless' => true,
'noSandbox' => true, // only when your container policy requires it
]);
try {
$page = $browser->createPage();
$page->setViewport(1200, 800)->await();
$page->navigate('https://example.com')->waitForNavigation();
$page->screenshot()->saveToFile(__DIR__ . '/example.png');
} finally {
$browser->close();
}Use noSandbox only after assessing the container boundary; disabling Chrome’s sandbox reduces isolation. Prefer a correctly configured sandbox for production where possible.
Render supplied markup and clip an element
<?php
require __DIR__ . '/vendor/autoload.php';
use HeadlessChromiumBrowserFactory;
$html = '<html><body><div id="ticket" style="width:900px;padding:40px;background:white">Ticket</div></body></html>';
$browser = (new BrowserFactory())->createBrowser(['headless' => true]);
try {
$page = $browser->createPage();
$page->setHtml($html)->await();
$page->evaluate('document.fonts.ready')->await();
$page->screenshot()->setClip(0, 0, 980, 180)->saveToFile(__DIR__ . '/ticket.webp');
} finally {
$browser->close();
}For a selector-specific crop, evaluate the element’s bounding rectangle, then pass those coordinates to the screenshot clip. Add a small wait after asynchronous application rendering so the rectangle is measured after layout stabilizes.
Make the capture deterministic
Set viewport and pixel density
CSS pixels and output pixels are different when device scale is greater than one. Fix the viewport for reproducible social cards and thumbnails, then choose a scale factor for sharper output. A 1200×630 CSS viewport at scale 2 produces a 2400×1260 raster image.
Wait for the page you actually need
- Wait for network idle when the page loads data and images over HTTP.
- Wait for a specific selector when an application has a clear “ready” element.
- Use an explicit delay only for unavoidable animations or third-party widgets.
- Disable transitions and animations with injected CSS when visual stability matters.
Handle images, fonts, and lazy loading
Full-page captures must scroll or otherwise trigger lazy images before the screenshot. Ensure image URLs are reachable from the browser process, and wait for document.fonts.ready before measuring text. If a font is blocked by CORS or an expiring signed URL, the browser may silently fall back to a different font and change line breaks.
Use print CSS only for print-like layouts
A screenshot uses screen media by default. If your stylesheet changes under @media print, explicitly choose the media mode supported by your library. Do not assume a PDF renderer’s pagination rules will match a raster screenshot.

Hosted API alternative
A hosted service accepts HTML/CSS or a URL over HTTP, runs the browser remotely, and returns an image URL or binary response. This removes Chrome maintenance from your PHP deployment, but you must review data handling, authentication, retention, request limits, and regional requirements before sending private markup, images, or fonts.
When this is the better operational choice
- Your PHP workers are serverless or otherwise cannot package Chromium.
- You need burst capacity without maintaining a browser pool.
- You want one API contract for screenshots from several languages.
- Your team prefers vendor-managed browser updates and patching.
Or skip the browser setup: ScreenshotNeo
ScreenshotNeo is a website screenshot API and MCP server. It accepts a URL and returns PNG, JPEG, WebP, or PDF. Before capture it accepts cookie/consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each cleanup step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and response headers report the page verdict and billing status.

Security and privacy boundaries
Sanitize untrusted HTML
Never pass user-supplied HTML straight into a privileged browser or PDF renderer. Remove scripts and dangerous URLs according to your application’s threat model, isolate the browser user, restrict outbound access where practical, and write output to a non-executable directory. mPDF’s documentation specifically warns that externally supplied HTML/CSS needs vetting beyond ordinary browser-level sanitization.
Protect credentials and internal pages
Keep API keys in environment variables, not templates or query strings visible in logs. If capturing an authenticated local page, use short-lived cookies or headers and ensure screenshots cannot expose secrets. A hosted API adds a data-transfer boundary; confirm that your privacy, residency, and retention requirements permit sending the content.

Performance, reliability, and cost
- Reuse browser processes carefully: launching Chrome for every request is slow; a controlled worker or browser pool reduces startup cost, but enforce page and memory limits.
- Bound every wait: network-idle waits can hang on analytics or streaming connections. Set a total timeout and a fallback selector/delay.
- Control concurrency: too many parallel pages can exhaust CPU and memory, causing blank captures or crashes.
- Cache stable outputs: hash the URL and relevant HTML/CSS inputs, and invalidate when assets change.
- Measure the result: record render duration, HTTP status, output dimensions, and browser errors. For hosted calls, retain the service’s response status and billing indicators.
- Budget honestly: local rendering costs infrastructure and maintenance; hosted pricing, concurrency, size, and retention vary and should be confirmed with the vendor before commitment.
Troubleshooting checklist
“Chrome executable not found” or process launch failure
Install Chrome/Chromium in the runtime image, expose its path to the library, and verify that the PHP worker’s PATH differs from your interactive shell. Confirm executable permissions.
Blank or partially rendered image
Wait for a ready selector or network idle, await fonts, and verify that image URLs are reachable from the server. For lazy content, trigger scrolling or use a full-page mode that loads lazy images.
Timeouts on otherwise valid pages
Third-party analytics, websockets, and ads can prevent network idle. Replace an unbounded idle wait with a selector wait plus a hard timeout, and block nonessential requests where your library supports it.
Different dimensions or text wrapping
Fix viewport, device scale, font loading, timezone, and locale. A missing web font or a different responsive breakpoint changes line breaks and element coordinates.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute403, CAPTCHA, or login wall
Respect the site’s access controls. Supply authorized headers/cookies only when you have permission. A screenshot service cannot legitimately bypass a CAPTCHA; treat the result as a failed capture and do not bill or retry indefinitely.

PDF output does not match the screenshot
PDF libraries implement document layout, often around CSS 2.1 and selected CSS3 features, rather than a full browser. Use Chromium for browser-faithful raster output and reserve Dompdf or mPDF for PDF deliverables.
Decision guide
- Choose Browsershot when your team is comfortable deploying Node, Puppeteer, and Chrome alongside PHP.
- Choose chrome-php/chrome when you want direct PHP control and can operate a compatible browser runtime.
- Choose a hosted API when browser operations, scaling, or serverless packaging outweigh data-transfer concerns.
- Choose Dompdf or mPDF only when the required artifact is a PDF, not a screenshot.
- Try ScreenshotNeo first when you want a hosted screenshot API with clean shots, billing only for successful captures, an MCP server for AI agents, and a $5 paid entry plan.
Frequently Asked Questions
Can PHP convert HTML to a PNG without JavaScript?
Yes. A headless Chrome workflow can render static HTML and CSS and save a PNG; JavaScript is only needed for client-rendered or interactive content.
Why does my screenshot have a white background?
The page may not set a background color, or the capture mode may not support transparency. Set the desired background in CSS or use a renderer option that explicitly enables a transparent background.

Usually store the image in object storage or a filesystem and keep its path, dimensions, hash, and creation metadata in the database. Store binaries in the database only when your storage and backup design specifically requires it.
Is a PDF library interchangeable with a screenshot library?
No. Dompdf and mPDF target PDF layout. Browser screenshot libraries target the pixels produced by Chrome or Chromium, so CSS and JavaScript behavior can differ substantially.
