IronPDF supports Linux for .NET 8, 7, 6, 5 and .NET Core applications, as well as Docker, Azure, AWS, macOS, and (naturally) Windows.

We recommend using .NET Core 3.1 and any other runtimes marked as LTS by Microsoft because they have guaranteed long-term support and are generally well tested on Linux.

No code changes are required to run IronPDF on Linux. Generally, IronPDF works out of the box thanks to hundreds of hours of testing and configuration by our engineers.

Linux support is important because many cloud services such as Azure Web Apps, Azure Functions, AWS EC2, AWS Lambda, Azure Devops, and Docker rely heavily on Linux. At Iron Software, we use these cloud tools regularly and understand that many of our Enterprise and SAAS customers do too.

Hardware Specification

IronPDF uses Chromium to render HTML to PDF. The Chromium engine renders PDFs with pixel-perfect accuracy similar to Chrome's print feature. The hardware specifications are primarily for running the Chromium engine, which takes most of the computing power.

• Minimum: 1 Core & 1.75 GB of RAM
• Recommended: 2 Cores & 8 GB of RAM or above

Officially Supported Linux Distros

We officially support and recommend the latest 64-bit Linux OS's below for "zero configuration" setup of IronPDF.

• Ubuntu 22
• Ubuntu 20
• Ubuntu 18
• Ubuntu 16
• Debian 11 [Currently the Microsoft Azure Default Linux Distro]
• Debian 10
• CentOS 8
• Fedora Linux 33
• Amazon AWS Linux 2

Read the AWS Lambda Setup Guide for IronPdf.

Please read "Other Linux Distros" below for advice on installing IronPDF on a version of Linux which is not officially supported.

We recommend using Microsoft's Official Docker Images. Other Linux distros are supported in part but may require manual configuration using apt-get. See "Common Dependency Patterns for Linux" at the end of this document.

Linux Automatic Setup

The default setting LinuxAndDockerDependenciesAutoConfig true will automatically attempt to install all dependencies for IronPDF to run on Linux. The first HTML-to-PDF operation may take longer than usual.

// This setting ensures IronPDF automatically installs dependencies needed for Linux and Docker environments
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

// This setting ensures IronPDF automatically installs dependencies needed for Linux and Docker environments
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;

' This setting ensures IronPDF automatically installs dependencies needed for Linux and Docker environments
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = True

Linux Optimized NuGet Packages

Install-Package IronPdf.Linux

There are NuGet Packages available for Linux optimized IronPDF deployments documented in our IronPDF advanced NuGet installation guide.

You can use this Linux optimized package and even develop on a Windows or macOS machine.

Alternatively, you can directly download the DLL for Linux.

Docker + Linux Setup

Please read our extensive documentation on using IronPDF on Docker if you need help setting up a Docker image that will use IronPDF.

Ubuntu Compatibility

Ubuntu is our most tested Linux operating system. This is because it is used heavily in the Azure infrastructure we use for continuous testing and deployment. This platform also has official Microsoft .NET support and Official Docker Images.

Ubuntu 20

We support Ubuntu 20 out of the box with zero configuration.

• Support Chrome and WebKit based HTML to PDF rendering Engines
• Officially support .NET Core 3.1, 5, 6 (LTS), 7 and 8 runtimes
• Unofficially, we support many other .NET Core runtimes on Ubuntu 20
• We run over 997 Unit tests on this platform before every release

Official Microsoft Docker Images:

• 64-bit Ubuntu 20.04 Docker Image for .NET Runtime 3.1 ('3.1-focal')
• 64-bit Ubuntu 20.04 Docker Image for .NET Runtime 5.0 ('5.0-focal')

Manual Ubuntu 20 Setup
If you wish to manually install or your app cannot be run with sudo admin privileges:

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

# Update package list
apt update

# Install required packages
apt install -y libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence1 libgdiplus libva-dev

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

# Update package list
apt update

# Install required packages
apt install -y libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence1 libgdiplus libva-dev

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

• IronCefSubprocess mentioned above is a binary within your application's bin folder. You may need to specify an exact path which may be in the runtimes subdirectory of bin.
• You may need sudo privileges.

Ubuntu 18

We support Ubuntu 18 out of the box with zero configuration.

• Support Chrome and WebKit based HTML to PDF rendering Engines
• Official support .NET Core 3.1 LTS and .NET 5 runtimes
• Unofficially, we support many other .NET Core runtimes on Ubuntu 18 and even 16
• We run comprehensive smoke tests on this platform before every release

Official Microsoft Docker Images:

• 64-bit Ubuntu 18.04 Docker Image for .NET Runtime 3.1 ('3.1-bionic')
• Although there is no official docker image for .NET 5 on Ubuntu 18, compatibility is very high.

Manual Ubuntu 18 Setup
If you wish to manually install or your app cannot be run with sudo admin privileges:

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

# Update package list
apt update

# Install required packages
apt install -y libc6 libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence-dev

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

Ubuntu 16

We have limited/unofficial support for Ubuntu 16. Ubuntu 16 has not been rigorously tested with IronPDF.

.NET on Ubuntu 16 is officially supported by Microsoft and is reported to work with IronPdf by many users. Developers may have to install apt-get dependencies manually.

• Chrome and WebKit normally work with manual config.
• .NET Core 3.1 LTS and .NET 5 runtimes have Microsoft support for Ubuntu 16.
• There are currently no official Microsoft Docker images for Ubuntu 16.

Manual Ubuntu 16 Setup
If you wish to manually install or your app cannot be run with sudo admin privileges:

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

# Update package list
apt update

# Install required packages

# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

Debian 9 and Lower

Debian 9 has not been officially tested and will not work out-of-the-box with IronPdf. However, .NET on Debian 9 is officially supported by Microsoft and can work with IronPdf if set up correctly (See "Common Dependency Patterns for Linux").

There are no official Docker images by Microsoft for .NET Core 3.1 or .NET 5.0 on Debian 9. We highly recommend migrating to Debian 10.

CentOS Compatibility

We actively like and support CentOS.

CentOS 8 Support

We support CentOS 8 out of the box with zero configuration.

• Support Chrome and WebKit based HTML to PDF rendering Engines
• Officially support .NET Core 3.1, 5, 6 (LTS), 7 and 8 runtimes
• Unofficially, we support many other .NET Core runtimes on CentOS
• We run comprehensive smoke tests on this platform before every release

Sadly there are no official Docker images by Microsoft for .NET Core 3.1 or .NET 5.0 on CentOS 8.

Manual CentOS 8 Setup
If you wish to manually install or your app cannot be run with sudo admin privileges:

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

# Update package list
dnf -y update

# Install required packages
dnf -y install glibc-devel nss at-spi2-atk libXcomposite libXrandr mesa-libgbm alsa-lib pango cups-libs libXdamage libxshmfence

# Make IronCefSubprocess executable

# Install required packages
dnf -y install glibc-devel nss at-spi2-atk libXcomposite libXrandr mesa-libgbm alsa-lib pango cups-libs libXdamage libxshmfence

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

CentOS 7 and Lower

CentOS 7 has not been tested and will not work out-of-the-box with IronPdf.

However, .NET on CentOS 7 is officially supported by Microsoft and would likely work with IronPdf if set up correctly (please read "Common Dependency Patterns for Linux") below.

There are no official Docker images by Microsoft for .NET Core 3.1 or .NET 5.0 on CentOS 7.

Amazon AWS Linux 2 Compatibility

We have working support for Amazon AWS Linux 2, which forms the basis of Amazon's cloud services such as EC2 and Lambda.

• There are no official Docker images by Microsoft for .NET Core 3.1 or .NET 5.0 on Amazon AWS Linux 2.
• We manually test for Amazon AWS Linux 2 compatibility as we develop IronPDF

We recommend that you read our IronPDF AWS Lambda guide which contains a working Docker file for IronPdf on AWS Lambda.

Amazon Linux 2 Manual Setup

chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

Please also read our documentation on our official support IronPdf for AWS Lambda that includes installation and logging on the Amazon cloud platform.

Fedora Linux Compatibility

Fedora Linux is supported.

We support Fedora Linux 33 out of the box with zero configuration.

• Support Chrome and WebKit based HTML to PDF rendering Engines
• Officially support .NET Core 3.1, 5, 6 (LTS), 7 and 8 runtimes
• We run comprehensive smoke tests on this platform before every release

Manual Fedora Linux Setup
If you wish to manually install or your app cannot be run with sudo admin privileges. This may also help with older or newer builds of Fedora Linux.

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

# Install required packages
dnf -y install glibc-devel nss at-spi2-atk libXcomposite libXrandr mesa-libgbm alsa-lib pango cups-libs libXdamage libxshmfence

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

# Install required packages
dnf -y install glibc-devel nss at-spi2-atk libXcomposite libXrandr mesa-libgbm alsa-lib pango cups-libs libXdamage libxshmfence

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

Alpine Linux Compatibility

Running IronPDF on Alpine Linux is not supported. We wish we could but we can't. Frankly, we like Alpine and hope this project continues and grows. As of 2023, Alpine still uses outdated "musl" C language libraries that do not allow chromium developers to fully support this OS yet.

Using Alpine Docker with IronPdfEngine in .NET 6

IronPdf provides a container image containing all IronPdf functionalities. This enables projects running on Alpine to access IronPdf functionalities by connecting to the IronPdfEngine container.

Step 1: Pull and Run IronPdf Engine Docker Image

Execute the following commands in your terminal to pull and run the IronPdf Engine Docker image:

# Pull IronPdf Engine Docker image
docker pull ironsoftwareofficial/ironpdfengine

# Run the IronPdf Engine Docker image
docker run -d -p 33350:33350 ironsoftwareofficial/ironpdfengine

# Pull IronPdf Engine Docker image
docker pull ironsoftwareofficial/ironpdfengine

# Run the IronPdf Engine Docker image
docker run -d -p 33350:33350 ironsoftwareofficial/ironpdfengine

Step 2: Set Up Console App

Create a new console application targeting .NET 6.
Install the IronPdf.Slim NuGet package using the NuGet Package Manager.

Other Linux Distros

You can also manually install the IronPDF prerequisites for Linux using apt-get, hfs, and yum. This allows you to use IronPDF on many unsupported Linux distros.

Generally, during installation for the first time, IronPDF will throw exceptions to tell you of any necessary system dependencies.

• IronCefSubprocess mentioned below is a binary within your application's bin folder. You may need to specify an exact path which may be in the runtimes subdirectory of bin.
• You may need sudo privileges.

If you are uncertain how to proceed with an unlisted Linux OS, investigate the dependencies for the Chromium browser on that OS.

If you want to vote for official support for a different Linux distro, please contact support@ironsoftware.com with your request.

Common Dependency Patterns for Linux
Please also study the dependency packages for other Linux OS's above.

# Update package list
apt update

# Install required packages
apt install -y libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence1

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

# Update package list
apt update

# Install required packages
apt install -y libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence1

# Make IronCefSubprocess executable
chmod 755 IronCefSubprocess
# Note: IronCefSubprocess is normally found at bin/runtimes/linux-x64/

IronCefSubprocess

IronCefSubprocess is a binary file within your application's bin folder. It needs to be executable by the .NET process.

E.g. (path may vary)

# Make IronCefSubprocess executable
chmod 755 bin/runtimes/linux-64/IronCefSubprocess

# Make IronCefSubprocess executable
chmod 755 bin/runtimes/linux-64/IronCefSubprocess

dotnet single-file publishing in Linux

If you choose to export your project as single-file publishing on Linux, this is how to do it:

# Publish as a single file for Linux
dotnet publish -r linux-x64 /property:PublishProfile=FolderProfile /bl

# Publish as a single file for Linux
dotnet publish -r linux-x64 /property:PublishProfile=FolderProfile /bl

Temp File Paths

Developers may need to specify a writable directory where temporary files can be created for some use cases.

A common, safe value for this path is /tmp/ in Linux, but ultimately it must be a path where the user can read and write files.

// Set IronPDF temporary path to /tmp/
string tmpPath = @"/tmp/";

IronPdf.Logging.Logger.LogFilePath = tmpPath;
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process);
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process);
IronPdf.Installation.TempFolderPath = tmpPath;
IronPdf.Installation.CustomDeploymentDirectory = tmpPath;

// Set IronPDF temporary path to /tmp/
string tmpPath = @"/tmp/";

IronPdf.Logging.Logger.LogFilePath = tmpPath;
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process);
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process);
IronPdf.Installation.TempFolderPath = tmpPath;
IronPdf.Installation.CustomDeploymentDirectory = tmpPath;

' Set IronPDF temporary path to /tmp/
Dim tmpPath As String = "/tmp/"

IronPdf.Logging.Logger.LogFilePath = tmpPath
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process)
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process)
IronPdf.Installation.TempFolderPath = tmpPath
IronPdf.Installation.CustomDeploymentDirectory = tmpPath
