Learn how to easily add and customize icon images for modules in Odoo. This guide provides step-by-step instructions for enhancing your Odoo interface with custom icons tailored to specific views.
Customizing the appearance of your Odoo modules not only enhances their visual appeal but also makes them easier to identify in the interface. One of the simplest yet effective ways to customize your module is by adding an icon image. This guide will walk you through the steps of adding an icon image to your Odoo module, helping you create a more professional and user-friendly experience.

Module icons in Odoo serve as visual identifiers, allowing users to quickly recognize and differentiate between various modules. These icons appear in the Apps menu, providing a more organized and visually appealing way to navigate through installed modules.
When you develop a custom module in Odoo, the icon is typically displayed as a blank placeholder unless you specify one. Adding a custom icon enhances the professional look of your module and helps users quickly locate it among others.
Before diving into the steps, ensure you have the following prerequisites ready:
1. Odoo 17 Installed: Make sure that Odoo 17 is installed and properly configured on your development environment. You can follow my previous guide, "How to Install Odoo 17 on Windows 11: A Step-by-Step Guide," if you need assistance.
2. Basic Understanding of Odoo Modules: You should have a basic understanding of Odoo module structure and development. If you are new to Odoo development, consider reviewing how to create a module in Odoo before proceeding with this guide.
3. Icon Image File: Prepare the icon image file you wish to use. Odoo supports PNG, JPEG, and SVG formats, but PNG is recommended for its transparency support and consistent display across different devices.
The first step is to prepare the icon image file. Here are some best practices to consider:
1. Image Size: The recommended size for Odoo module icons is 128x128 pixels. This ensures that the icon looks crisp on all screen sizes, including high-resolution displays.
2. File Format: PNG is the preferred format for Odoo module icons due to its support for transparency and lossless compression.
3. Naming Convention: Name your icon file icon.png. This is the standard naming convention that Odoo looks for when displaying module icons.
4. Design Tips: Ensure that the icon design is simple and easily recognizable, with good contrast against both light and dark backgrounds. Avoid overly complex designs as they may not render well at smaller sizes.
With your icon image ready, it’s time to add it to your Odoo module. Follow these steps:
1. Place the Icon in Your Module Directory: The icon image file should be placed in the root directory of your module. For example, if your module is named custom_module, the directory structure should look like this:
custom_module/
├── __init__.py
├── __manifest__.py
├── models/
├── views/
└── icon.png
2. Modify the __manifest__.py File: You need to tell Odoo to use your icon image. Open your module’s __manifest__.py file and add the following key-value pair:
'icon': '/custom_module/static/description/icon.png',
Note: The path provided here is relative to the Odoo server’s static file structure. Ensure that your icon file is correctly placed and the path matches its location.
Odoo allows you to customize the icon for specific views within your module. This is particularly useful if your module has multiple submodules or features that you want to visually differentiate.
1. Create Subdirectories for Icons: If you have different icons for different parts of your module, you can organize them into subdirectories. For instance, you might have:
custom_module/
├── static/
│ └── description/
│ ├── main_icon.png
│ └── submodule_icon.png
└── __manifest__.py
2. Update the Manifest File Accordingly: In your __manifest__.py file, you can specify different icons for different views or parts of your module by adjusting the path:
'icon': '/custom_module/static/description/main_icon.png',
'submodule_icon': '/custom_module/static/description/submodule_icon.png',
Odoo will use the icon key for the main module and the submodule_icon key for the specific submodule or feature.
After adding the icon to your module, it’s important to test it to ensure that it displays correctly.
1. Restart Odoo: For the changes to take effect, restart your Odoo server.
./odoo-bin -c odoo.conf
2. Update the Module List: Navigate to the Apps menu in Odoo and update the module list. If you don’t see your icon immediately, you may need to clear your browser’s cache or force a refresh.
3. Check Icon Appearance: Verify that the icon appears correctly in the Apps menu. Ensure it looks as expected across different screen sizes and resolutions.
4. Troubleshooting Common Issues:
Icon Not Displaying: If your icon doesn’t display, double-check the file path in your __manifest__.py file. Ensure the image is correctly named and placed in the correct directory.
Distorted or Blurry Icon: If your icon appears blurry or distorted, make sure the image is in the correct resolution (128x128 pixels) and that it was saved in a lossless format like PNG.
Once you’ve successfully added an icon to your module, you may want to explore further customization options:
1. Dynamic Icons: In some advanced use cases, you may want your module’s icon to change based on certain conditions (e.g., user roles or module states). This requires additional coding and integrating logic within your module.
2. Theming and Branding: If you’re developing multiple modules for a specific client or organization, consider creating a consistent icon theme. This involves using similar colors, shapes, or design elements across all module icons to reinforce brand identity.
3. SVG Icons: While PNG is the recommended format for simplicity, SVG icons offer scalability and can be a good choice if you need vector graphics that scale well at any size. Ensure that your SVG icons are compatible with Odoo’s rendering engine and that they maintain visual integrity across different devices.
If you plan to distribute your module or use it on another Odoo instance, you’ll want to ensure that the icon is included and correctly packaged.
1. Verify All Files: Before packaging, double-check that all necessary files, including your icon, are present in the module directory.
2. Create a ZIP Archive: Package your module as a ZIP file, including the icon.png file.
3. Test on a Fresh Odoo Instance: To ensure everything works as expected, install your module on a fresh Odoo instance and verify that the icon displays correctly.
4. Distribute via Odoo Apps Store: If you’re sharing your module publicly, upload it to the Odoo Apps Store. Make sure to include a description of your module’s features and highlight the custom icon as a visual enhancement.
Adding an icon image to your Odoo module is a simple yet powerful way to improve the user experience and give your module a professional touch. By following the steps outlined in this guide, you can easily customize your module’s appearance and make it stand out in the Odoo interface.
Whether you’re developing modules for internal use or distributing them to clients or the wider Odoo community, taking the time to add a custom icon demonstrates attention to detail and a commitment to quality. As you continue to develop in Odoo, consider exploring other visual customization options to further enhance the look and feel of your modules.
Remember, first impressions matter, and a well-designed icon can make your module more approachable and user-friendly. Happy developing, and may your Odoo modules always stand out with style!
