title: Introduction
---
[Gotenberg](https://github.com/thecodingmachine/gotenberg/) is a Docker-powered stateless API for converting HTML, Markdown and Office documents to PDF.
* HTML and Markdown conversions using Google Chrome headless
* Office conversions (.txt, .rtf, .docx, .doc, .odt, .pptx, .ppt, .odp and so on) using [unoconv](https://github.com/dagwieers/unoconv)
* Performance: Google Chrome and Libreoffice (unoconv) started once in the background thanks to PM2
* Failure prevention: PM2 automatically restarts previous processes if they fail
* Assets: send your header, footer, images, fonts, stylesheets and so on for converting your HTML and Markdown to beaufitul PDFs!
* Easily interact with the API using our [Go](https://github.com/thecodingmachine/gotenberg/pkg) and [PHP](https://github.com/thecodingmachine/gotenberg-php-client) libraries

title: Install
---
Gotenberg is shipped within a Docker image.
You may start it with:
```bash
$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:3
```
> The API will be available at [http://localhost:3000](http://localhost:3000).
Or add it in your Docker Compose stack:
```yaml
version: '3'
services:
# your others services
gotenberg:
image: thecodingmachine/gotenberg:3
```
> The API will be available under `gotenberg:3000` in your Docker Compose network.
It may also be deployed with Kubernetes.
In the following examples, we will assume your
Gotenberg API is available at [http://localhost:3000](http://localhost:3000).
## Go client
```bash
$ go get -u github.com/thecodingmachine/gotenberg
```
## PHP client
Unless your project already has a PSR7 `HttpClient`, install `php-http/guzzle6-adapter`:
```bash
$ composer require php-http/guzzle6-adapter
```
Then the PHP client:
```bash
$ composer require thecodingmachine/gotenberg-php-client
```

title: HTML
---
Gotenberg provides the endpoint `/convert/html` for HTML conversions.
It accepts `POST` requests with a `multipart/form-data` Content-Type.
## Basic
The only requirement is to send a file named `index.html`: it is the file
which will be converted to PDF.
For instance:
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My PDF</title>
</head>
<body>
<h1>Hello world!</h1>
</body>
</html>
```
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
> result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg/pkg"
func main() {
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewHTMLRequest("index.html")
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', 'index.html');
$request = new HTMLRequest($index);
$dirPath = "/foo";
$filename = $client->store($request, $dirPath);
```
## Header and footer
You may also add a header and/or a footer in the resulting PDF.
Respectively, a file named `header.html` and `footer.html`.
Each of them **has to be a complete HTML document**:
```html
<html>
<head>
<style>
body {
font-size: 8rem;
margin: 4rem auto;
}
</style>
</head>
<body>
<p>
<span class="pageNumber"></span> of <span class="totalPages"></span>
</p>
</body>
</html>
```
The following classes allow you to inject printing values:
* `date`: formatted print date
* `title`: document title
* `pageNumber`: current page number
* `totalPage`: total pages in the document
> **Attention:** the CSS properties are independant of the ones used in the `index.html` file.
> Also, `footer.html` CSS properties override the ones from `header.html`.
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form files=@header.html \
--form files=@footer.html \
> result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg/pkg"
func main() {
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewHTMLRequest("index.html")
req.SetHeader("header.html")
req.SetFooter("footer.html")
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', 'index.html');
$header = DocumentFactory::makeFromPath('header.html', 'header.html');
$footer = DocumentFactory::makeFromPath('footer.html', 'footer.html');
$request = new HTMLRequest($index);
$request->setHeader($header);
$request->setFooter($footer);
$dirPath = "/foo";
$filename = $client->store($request, $dirPath);
```
## Assets
You may also send additional files. For instance: images, fonts, stylesheets and so on.
The only requirement is to make sure that their paths
are on the same level as the `index.html` file.
In others words, this will work:
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My PDF</title>
</head>
<body>
<h1>Hello world!</h1>
<img src="img.png">
</body>
</html>
```
But this won't:
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My PDF</title>
</head>
<body>
<h1>Hello world!</h1>
<img src="/foo/img.png">
</body>
</html>
```
You may also use *remote* paths for Google fonts, images and so on.
> If you want to install fonts directly in the Gotenberg Docker image,
> see to the [fonts section](#office.fonts).
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form files=@style.css \
--form files=@img.png \
--form files=@font.woff \
> result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg/pkg"
func main() {
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewHTMLRequest("index.html")
req.SetAssets([]string{
"font.woff",
"img.gif",
"style.css",
})
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', 'index.html');
$assets = [
DocumentFactory::makeFromPath('style.css', 'style.css'),
DocumentFactory::makeFromPath('img.png', 'img.png'),
DocumentFactory::makeFromPath('font.woff', 'font.woff'),
];
$request = new HTMLRequest($index);
$request->setAssets($assets);
$dirPath = "/foo";
$filename = $client->store($request, $dirPath);
```
## Paper size, margins, orientation
You may also customize the resulting PDF format.
By default, it will be rendered with `A4` size, `1 inch` margins and `portrait` orientation.
> Paper size and margins have to be provided in `inches`.
> Also, you have to set both `paperWidth` and `paperHeight`. Same for margins.
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form paperWidth=8.27 \
--form paperHeight=11.27 \
--form marginTop=0 \
--form marginBottom=0 \
--form marginLeft=0 \
--form marginRight=0 \
--form landscape=true \
> result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg/pkg"
func main() {
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewHTMLRequest("index.html")
req.SetPaperSize(gotenberg.A4)
req.SetMargins(gotenberg.NoMargins)
req.SetLandscape(true)
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
use TheCodingMachine\Gotenberg\Request;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', 'index.html');
$request = new HTMLRequest($index);
$request->setPaperSize(Request::A4);
$request->setMargins(Request::NO_MARGINS);
$request->setLandscape(true);
$dirPath = "/foo";
$filename = $client->store($request, $dirPath);

title: Markdown
---
Gotenberg provides the endpoint `/convert/markdown` for Markdown conversions.
It accepts `POST` requests with a `multipart/form-data` Content-Type.
## Basic
Markdown conversions work the same as HTML conversions.
Only difference is that you have access to the Go template function `toHTML`
in the file `index.html`. This function will convert a given markdown file to HTML.
For instance:
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My PDF</title>
</head>
<body>
{{ toHTML .DirPath "file.md" }}
</body>
</html>
```
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/markdown \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form files=@file.md \
> result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg/pkg"
func main() {
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewMarkdownRequest("index.html", []string{"file.md"})
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\MarkdownRequest;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', 'index.html');
$markdowns = [
DocumentFactory::makeFromPath('file.md', 'file.md'),
];
$request = new MarkdownRequest($index, $markdowns);
$dirPath = "/foo";
$filename = $client->store($request, $dirPath);

title: Office
---
Gotenberg provides the endpoint `/convert/office` for Office document conversions.
It accepts `POST` requests with a `multipart/form-data` Content-Type.
## Basic
You may send one or more Office documents. Following file extensions are accepted:
* `.txt`
* `.rtf`
* `.doc`
* `.docx`
* `.odt`
* `.xls`
* `.xlsx`
* `.ods`
* `.ppt`
* `.pptx`
* `.odp`
All files will be merged into a single resulting PDF.
> **Attention:** currently, `unoconv` cannot perform concurrent conversions.
> That's why for Office conversions, the API does only one conversion at a time.
> See the [scalability section](#scalability) to find how to mitigate this issue.
### cURL

$ curl --request POST \
--url http://localhost:3000/convert/office \

title: Merge
---
Gotenberg provides the endpoint `/merge` for merging PDFs.
It accepts `POST` requests with a `multipart/form-data` Content-Type.
## Basic
Nothing special here: you may send one or more PDF files and the API
will merge them and return the resulting PDF file.

title: Webhook
---
All endpoints accept a form field named `webhookURL`.
If provided, the API will send the resulting PDF file in a `POST` request with the `application/pdf` Content-Type
to given URL.
By doing so, your requests to the API will be over before the conversions are actually done!
## Examples
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form webhookURL='http://myapp.com/webhook/'

c := &gotenberg.Client{Hostname: "http://localhost:3000"}
req, _ := gotenberg.NewHTMLRequest("index.html")
req.SetWebhookURL("http://myapp.com/webhook/")
dest := "result.pdf"
resp, _ := c.Post(req)
}

title: Scalability
---
The API being stateless, you may scale it as much as you want.
For instance, using the following Docker Compose file:
```yaml
version: '3'
services:
# your others services
gotenberg:
image: thecodingmachine/gotenberg:3
```
You may now launch your services using:
```bash
$ docker-compose up --scale gotenberg=your_number_of_instances
```
When requesting the Gotenberg service with your client(s), Docker will automatically
redirect a request to a Gotenberg container according to the round-robin strategy.
