a [full list of our 50+ features](https://ironpdf.com/java/features/?utm_source=nuget&utm_medium=organic&utm_campaign=readme&utm_content=featureslist)*
## Using IronPDF
### Define IronPDF as a Java Dependency
To define IronPDF as a dependency, please add the following excerpt to your pom.xml:
```xml
com.ironsoftware
ironpdf
20xx.xx.xxxx
```
### Start writing Java code
Once the dependence is defined, you can get started by adding the `import com.ironsoftware.ironpdf.*` statement to the top of your Java code. Here is
a sample HTML to PDF example to get started:
```java
PdfDocument pdfDocument = PdfDocument.renderHtmlAsPdf("
~Hello World~
Made with IronPDF!");
pdfDocument.saveAs(Paths.get("html_saved.pdf"));
```
This is another example which demonstrates URL to PDF:
```java
PdfDocument pdfDocument = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java");
pdfDocument.saveAs(Paths.get("url_saved.pdf"));
```
### Settings
Note: Please note that all settings, logging, and licensing operations must be executed before any IronPDF methods are called.
#### Applying License Key
```java
com.ironsoftware.ironpdf.License.setLicenseKey("YOUR-LICENSE-KEY");
```
#### Logging
IronPdf Java uses the [slf4j](https://www.slf4j.org/) logger. To enable logging use:
```java
com.ironsoftware.ironpdf.Settings.setDebug(true);
```
To specify the IronPdfEngine log path add:
```java
com.ironsoftware.ironpdf.Settings.setLogPath(Paths.get("C:/tmp/myIronPdfEngineLog.log"));
```
Not familiar with slf4j? Just add this to your `pom.xml`:
```xml
org.slf4j
slf4j-simple
2.0.3
```
## About IronPDF for Java
`IronPDF for Java` is based on `IronPDF for .NET`, it will generally be about 1 version behind.
IronPDF for Java uses gRPC to communicate with the `IronPdfEngine`, which consumes `IronPDF for .NET`
## About IronPDF Engine
`IronPdfEngine` is the core of IronPdf. To use `IronPdf for Java` `IronPdfEngine` binaries is required.
The `IronPdfEngine` process will start when you call any IronPdf function for the first time, and stop when your application is closed, or when it enters an idle stage.
By default `IronPdf for Java` will download `IronPdfEngine` binaries on the first run (or when it cannot find the binaries).
> Note: For macOS, `IronPdfEngine` binaries that download on the first run might not work in your system (Gatekeeper on macOS).
Please use `IronPdfEngine` as a maven dependency instead (next section)
### Install IronPDF Engine as a Maven Dependency
By adding IronPdfEngine as a Maven dependency, the binaries will be downloaded during the loading of dependencies:
- This approach will avoid a lengthy startup process, as the IronPdfEngine binaries will already be downloaded.
- Moreover, it will be beneficial for deployment setups that do not allow downloading from external sources.
Simply add one or multiple of the following code snippets to your **pom.xml** file if you are working on a multiplatform app:
#### For windows x64
```xml
com.ironsoftware
ironpdf-engine-windows-x64
20xx.xx.xxxx
```
#### For windows x86
```xml
com.ironsoftware
ironpdf-engine-windows-x86
20xx.xx.xxxx
```
#### For Linux x64
```xml
com.ironsoftware
ironpdf-engine-linux-x64
20xx.xx.xxxx
```
#### For macOS x64 (Intel)
```xml
com.ironsoftware
ironpdf-engine-macos-x64
20xx.xx.xxxx
```
#### For macOS Arm (Apple Silicon)
```xml
com.ironsoftware
ironpdf-engine-macos-arm64
20xx.xx.xxxx
```
