Convert html to an image, pdf or string

Convert a webpage to an image or pdf using headless Chrome

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

Custom node and npm binaries

Depending on your setup, node or npm might be not directly available to Browsershot. If you need to manually set these binary paths, you can do this by calling the setNodeBinary and setNpmBinary method.

Browsershot::html('Foo')
    ->setNodeBinary('/usr/local/bin/node')
    ->setNpmBinary('/usr/local/bin/npm');

By default, Browsershot will use node and npm to execute commands.

Custom include path

If you don't want to manually specify binary paths, but rather modify the include path in general, you can set it using the setIncludePath method.

Browsershot::html('Foo')
    ->setIncludePath('$PATH:/usr/local/bin')

Setting the include path can be useful in cases where node and npm can not be found automatically.

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 length of the page by using fullPage().

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);

Mobile emulation

You can emulate a mobile view with the mobile and touch methods. mobile will set the display to take into account the page's meta viewport, as Chrome mobile would. touch will set the browser to emulate touch functionality, hence allowing spoofing for pages that check for touch. Along with the userAgent method, these can be used to effectively take a mobile screenshot of the page.

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

Backgrounds

If you want to ignore the website's background when capturing a screenshot, use the hideBackground() method.

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

Dismiss dialogs

Javascript pop ups such as alerts, prompts and confirmations cause rendering of the site to stop what leads to an empty screenshot. Calling dismissDialogs() method automatically closes such popups allowing the screenshot to be taken.

Browsershot::url('https://example.com')
    ->dismissDialogs()
    ->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 width 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);

Disable sandboxing

When running Linux in certain virtualization enviroments it might need to disable sandboxing.

Browsershot::url('https://example.com')
   ->noSandbox()
   ...

Ignore HTTPS errors

You can ignore HTTPS errors, if necessary.

Browsershot::url('https://example.com')
   ->ignoreHttpsErrors()
   ...

Specify a proxy Server

You can specify a proxy server to use when connecting. The argument passed to setProxyServer will be passed to the --proxy-server= option of Chromium. More info here: https://www.chromium.org/developers/design-documents/network-settings#TOC-Command-line-options-for-proxy-settings

Browsershot::url('https://example.com')
   ->setProxyServer("1.2.3.4:8080")
   ...

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.
