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>
```
### Guzzle
```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.HTMLRequest{
IndexFilePath: "index.html",
}
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
TODO
## 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`.
### Guzzle
```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.HTMLRequest{
IndexFilePath: "index.html",
Options: &gotenberg.HTMLOptions{
HeaderFilePath: "header.html",
FooterFilePath: "footer.html",
},
}
dest := "result.pdf"
c.Store(req, dest)
}
```

## 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).
### Guzzle
```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.HTMLRequest{
IndexFilePath: "index.html",
AssetFilePaths: []string{
"style.css",
"img.png",
"font.woff",
},
}
dest := "result.pdf"
c.Store(req, dest)
}
```
### PHP
TODO
## Paper size, margins, orientation
You may also customize the resulting PDF paper.
By default, it will be rendered in `A4` size with `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.
### Guzzle
```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.HTMLRequest{
IndexFilePath: "index.html",
Options: &gotenberg.HTMLOptions{
PaperSize: gotenberg.A4,
PaperMargins: gotenberg.NoMargins,
Landscape: true
},
}
dest := "result.pdf"
c.Store(req, dest)
}
