Convert a webpage to an image or pdf using headless Chrome

Latest Version Software License Build Status StyleCI SensioLabsInsight Total Downloads

The package can convert a webpage to an image or pdf. The conversion is done behind the scenes by Puppeteer which controls a headless version of Google Chrome.

Here's a quick example:

use Spatie\Browsershot\Browsershot;

// an image will be saved
Browsershot::url('https://example.com')->save($pathToImage);

It will save a pdf if the path passed to the save method has a pdf extension.

// a pdf will be saved
Browsershot::url('https://example.com')->save('example.pdf');

You can also use an arbitrary html input, simply replace the url method with html:

Browsershot::html('<h1>Hello world!!</h1>')->save('example.pdf');

Browsershot also can get the body of an html page after JavaScript has been executed:

Browsershot::url('https://example.com')->bodyHtml(); // returns the html of the body

Requirements

This package requires node 7.6.0 or higher and the Puppeteer Node library.

On MacOS you can install Puppeteer in your project via NPM:

npm install puppeteer

Or you could opt to just install it globally

npm install puppeteer --global

On a Forge provisioned Ubuntu 16.04 server you can install the latest stable version of Chrome like this:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget
sudo npm install --global --unsafe-perm puppeteer
sudo chmod -R o+rx /usr/lib/node_modules/puppeteer/.local-chromium

Installation

This package can be installed through Composer.

composer require spatie/browsershot

Usage

In all examples it is assumed that you imported this namespace at the top of your file

use Spatie\Browsershot\Browsershot;

Screenshots

Here's the easiest way to create an image of a webpage:

Browsershot::url('https://example.com')->save($pathToImage);

Sizing the image

By default the screenshot will be a png and it's size will match the resolution you use for your desktop. Want another size of screenshot? No problem!

Browsershot::url('https://example.com')
    ->windowSize(640, 480)
    ->save($pathToImage);

You can also set the size of the output image independently of the size of window. Here's how to resize a screenshot take with a resolution of 1920x1080 and scale that down to something that fits inside 200x200.

Browsershot::url('https://example.com')
    ->windowSize(1920, 1080)
    ->fit(Manipulations::FIT_CONTAIN, 200, 200)
    ->save($pathToImage);

You can screenshot only a portion of the page by using clip.

Browsershot::url('https://example.com')
    ->clip($x, $y, $width, $height)
    ->save($pathToImage);

Manipulating the image

You can use all the methods spatie/image provides. Here's an example where we create a greyscale image:

Browsershot::url('https://example.com')
    ->windowSize(640, 480)
    ->greyscale()
    ->save($pathToImage);

Taking a full page screenshot

You can take a screenshot of the full lenght of the pages by using fullPage(). The resulting can be quite long.

Browsershot::url('https://example.com')
    ->fullPage()
    ->save($pathToImage);

Setting the device scale

You can also capture the webpage at higher pixel densities by passing a device scale factor value of 2 or 3. This mimics how the webpage would be displayed on a retina/xhdpi display.

Browsershot::url('https://example.com')
    ->deviceScaleFactor(2)
    ->save($pathToImage);

PDFs

Browsershot will save a pdf if the path passed to the save method has a pdf extension.

// a pdf will be saved
Browsershot::url('https://example.com')->save('example.pdf');

Alternatively you can explicitly use the savePdf method:

Browsershot::url('https://example.com')->savePdf('example.pdf');

You can also pass some html which will be converted to a pdf.

Browsershot::html($someHtml)->savePdf('example.pdf');

Sizing the pdf

You can specify the widht and the height in millimeters

Browsershot::html($someHtml)
   ->paperSize($width, $height)
   ->save('example.pdf');

Setting margins

Margins can be set in millimeters.

Browsershot::html($someHtml)
   ->margins($top, $right, $bottom, $left)
   ->save('example.pdf');

Headers and footers

By default a PDF will not show the header and a footer generated by Chrome. Here's how you can make the header and footer appear.

Browsershot::html($someHtml)
   ->showBrowserHeaderAndFooter()
   ->save('example.pdf');

Backgrounds

By default, the resulting PDF will not show the background of the html page. If you do want the background to be included you can call showBackground:

Browsershot::html($someHtml)
   ->showBackground()
   ->save('example.pdf');

Landscape orientation

Call landscape if you want to resulting pdf to be landscape oriented.

Browsershot::html($someHtml)
   ->landscape()
   ->save('example.pdf');

Only export specific pages

You can control which pages should be export by passing a print range to the pages method. Here are some examples of valid print ranges: 1, 1-3, 1-5, 8, 11-13.

Browsershot::html($someHtml)
   ->pages('1-5, 8, 11-13')
   ->save('example.pdf');

HTML

Browsershot also can get the body of an html page after JavaScript has been executed:

Browsershot::url('https://example.com')->bodyHtml(); // returns the html of the body

Misc

If, for some reason, you want to set the user agent Google Chrome should use when taking the screenshot you can do so:

Browsershot::url('https://example.com')
    ->userAgent('My Special Snowflake Browser 1.0')
    ->save($pathToImage);

The default timeout of Browsershot is set to 60 seconds. Of course, you can modify this timeout:

Browsershot::url('https://example.com')
    ->timeout(120)
    ->save($pathToImage);

Security

If you discover any security related issues, please email freek@spatie.be instead of using the issue tracker.

Alternatives

If you're not able to install Node and Puppeteer, take a look at v2 of browserhot, which uses Chrome headless CLI to take a screenshot. v2 is not maintained anymore, but should work pretty well.

If using headless Chrome does not work for you take a lookat at v1 of this package which uses the abandoned PhantomJS binary.
