+## Overview
+
+[C2PA Tool](https://github.com/contentauth/c2patool), invoked as `c2patool`, reads, creates, and
+validates Content Credentials in supported media files. Content Credentials use the
+Coalition for Content Provenance and Authenticity (C2PA) standard to record media provenance.
+
+You can install C2PA Tool on 64-bit Arm Linux, macOS on Apple silicon, or Windows on Arm.
+The Linux instructions cover Ubuntu and Debian.
+
+Homebrew and Cargo install the version available from their package source. For release
+information, see [C2PA Tool releases](https://github.com/contentauth/c2patool/releases).
+
+## Install on macOS
+
+Install [Homebrew](https://brew.sh/) if it isn't already available, then install C2PA Tool:
+
+```console
+brew install c2patool
+```
+
+## Install on Arm Linux
+
+Prebuilt Linux releases target `x86_64`. Use Cargo to build and install a native `aarch64`
+executable.
+
+Install the build dependencies on Ubuntu or Debian:
+
+```console
+sudo apt update
+sudo apt install -y build-essential pkg-config libssl-dev
+```
+
+Install [Rust](/install-guides/rust/) to obtain Cargo, then install C2PA Tool:
+
+```console
+cargo install c2patool --locked
+```
+
+Cargo installs `c2patool` in `$HOME/.cargo/bin`.
+
+## Install on Windows on Arm
+
+Prebuilt Windows releases target `x86_64`. Use Cargo to build and install a native ARM64 executable.
+
+Install the Microsoft C++ Build Tools and [Rust](https://www.rust-lang.org/tools/install) with the
+MSVC toolchain for ARM64. Open a new PowerShell window and run:
+
+```console
+cargo install c2patool --locked
+```
+
+Cargo installs `c2patool.exe` in `%USERPROFILE%\.cargo\bin`.
+
+## Verify the installation
+
+Print the installed version:
+
+```console
+c2patool --version
+```
+
+The output reports `c2patool` followed by the installed version number.
+
+Display the command summary:
+
+```console
+c2patool --help
+```
+
+The expected output starts with:
+
+```output
+Tool for displaying and creating C2PA manifests.
+```
+
+## Troubleshooting
+
+If your shell can't find `c2patool`, open a new terminal. For a Cargo installation, confirm that
+`$HOME/.cargo/bin` on Linux or `%USERPROFILE%\.cargo\bin` on Windows is in your `PATH`.
+
+## Update C2PA Tool
+
+On macOS, run:
+
+```console
+brew update
+brew upgrade c2patool
+```
+
+For a Cargo installation, run:
+
+```console
+cargo install c2patool --locked --force
+```
+
+## Uninstall C2PA Tool
+
+For a Homebrew installation, run:
+
+```console
+brew uninstall c2patool
+```
+
+For a Cargo installation, run:
+
+```console
+cargo uninstall c2patool
+```

+title: ExifTool
+description: Install ExifTool on macOS, Linux on Arm, or Windows on Arm to read and write media metadata from the command line.

+
+## Overview
+
+[ExifTool](https://exiftool.org/) reads and writes metadata in image, audio, and video files.
+You can install it on macOS on Apple silicon, 64-bit Arm Linux, or Windows 11 on Arm.
+On Windows on Arm, you use the Windows x64 executable under emulation.
+
+Package-manager commands install the version available from your package source. See the
+[ExifTool download page](https://exiftool.org/) for current releases.
+
+## Install on macOS
+
+Install [Homebrew](https://brew.sh/) if it isn't already available, then install ExifTool:
+
+```console
+brew install exiftool
+```
+
+## Install on Arm Linux
+
+On Ubuntu and Debian, install the `libimage-exiftool-perl` package:
+
+```console
+sudo apt update
+sudo apt install libimage-exiftool-perl
+```
+
+On Fedora, install the [perl-Image-ExifTool package](https://packages.fedoraproject.org/pkgs/perl-Image-ExifTool/perl-Image-ExifTool/):
+
+```console
+sudo dnf install perl-Image-ExifTool
+```
+
+Both packages provide the `exiftool` command and its Perl dependencies.
+
+## Install on Windows 11 on Arm
+
+The Windows x64 executable runs through
+[x64 application emulation on Windows 11 on Arm](https://learn.microsoft.com/en-us/windows/arm/apps-on-arm-x86-emulation).
+
+Follow the [official Windows installation instructions](https://exiftool.org/install.html#Windows):
+
+1. Download the **64-bit Windows Executable** ZIP from the [ExifTool download page](https://exiftool.org/).
+2. Extract the archive into a permanent folder in your user directory.
+3. Rename `exiftool(-k).exe` to `exiftool.exe`. Keep its accompanying `exiftool_files` folder beside it.
+4. Add the folder containing `exiftool.exe` to your user's `Path` environment variable.
+5. Open a new PowerShell window so it picks up the change.
+
+## Verify the installation
+
+Print the installed version:
+
+```console
+exiftool -ver
+```
+
+The output is similar to:
+
+```output
+13.55
+```
+
+Your version can differ. List the available metadata tags to confirm ExifTool runs:
+
+```console
+exiftool -list
+```
+
+The output begins with `Available tags:` followed by tag names.
+
+## Troubleshooting
+
+If your shell can't find `exiftool`, open a new terminal and confirm that the directory containing
+`exiftool` is in your `PATH`. On Windows, also check that the executable is named `exiftool.exe`
+and that `exiftool_files` is still beside it.
+
+If Ubuntu cannot locate the package, check that the `universe` repository is enabled for your Ubuntu
+release, then run `sudo apt update` again.

+title: libjpeg-turbo
+description: Install libjpeg-turbo on macOS, Linux on Arm, or Windows on Arm to encode, decode, and transform JPEG images.

+
+## Overview
+
+[libjpeg-turbo](https://www.libjpeg-turbo.org/) provides JPEG encoding and decoding libraries and
+command-line tools. The tools include `cjpeg` for encoding, `djpeg` for decoding, and `jpegtran`
+for transforming JPEG images.
+
+You can install the tools on macOS on Apple silicon, 64-bit Arm Linux, or Windows on Arm.
+Package-manager commands on macOS and Linux install the version available from your package source.
+
+## Install on macOS
+
+Install [Homebrew](https://brew.sh/) if it isn't already available, then install the
+[jpeg-turbo package](https://formulae.brew.sh/formula/jpeg-turbo):
+
+```console
+brew install jpeg-turbo
+```
+
+## Install on Arm Linux
+
+On Ubuntu and Debian, install the `libjpeg-turbo-progs` package:
+
+```console
+sudo apt update
+sudo apt install libjpeg-turbo-progs
+```
+
+On Fedora, install the [libjpeg-turbo-utils package](https://packages.fedoraproject.org/pkgs/libjpeg-turbo/libjpeg-turbo-utils/):
+
+```console
+sudo dnf install libjpeg-turbo-utils
+```
+
+Both packages provide `jpegtran` and the other command-line tools. Installing only the JPEG
+runtime library doesn't provide these tools.
+
+## Install on Windows on Arm
+
+{{% notice Note %}}
+The following steps use libjpeg-turbo version 3.1.4.1. You can use another version that provides
+a native ARM64 installer. Replace the installer with the file for your chosen version.
+To find the latest version, see [libjpeg-turbo releases](https://github.com/libjpeg-turbo/libjpeg-turbo/releases).
+{{% /notice %}}
+
+1. Download `libjpeg-turbo-3.1.4.1-vc-arm64.exe` from the
+   [libjpeg-turbo 3.1.4.1 release](https://github.com/libjpeg-turbo/libjpeg-turbo/releases/tag/3.1.4.1).
+2. Run the installer and note the installation directory.
+3. Add the installation's `bin` directory, containing `jpegtran.exe`, to your user's `Path`
+   environment variable.
+4. Open a new PowerShell window so it picks up the change.
+
+## Verify the installation
+
+Print the installed version:
+
+```console
+jpegtran -version
+```
+
+The output is similar to:
+
+```output
+libjpeg-turbo version 3.1.4.1 (build 20260327)
+```
+
+Your version and build can differ. A successful version check confirms that your terminal can
+find and run `jpegtran`.
+
+## Troubleshooting
+
+If your shell can't find `jpegtran`, open a new terminal and confirm that the directory containing the
+executable is in your `PATH`. On Windows, check for `jpegtran.exe` in the installation's `bin`
+directory. On Linux, check that you installed the command-line tools package for your distribution.
+
+If Ubuntu cannot locate the package, check that the `universe` repository is enabled for your
+release, then run `sudo apt update` again.
