+title: How to change the Login Page and Nav Bar Logo
+slug: /how-to-guides/custom-logo/how-to-add-custom-logo
+---
+
+To change the Logo for the application, we need to update logo at two locations.
+
+1. Login Page
+
+<Image src="/images/how-to-guides/custom-logo/login-Page-Logo.png" alt="loginPage-image"/>
+
+2. Navigation Bar
+
+<Image src="/images/how-to-guides/custom-logo/nav-Bar-Logo.png" alt="navBar-image"/>
+
+# How to add a custom logo for the application
+
+### Step 1: Get the image size as per the following formats.
+
+- Login Page (1 px x 2px)
+- Navigation Bar (1 px x 2px)
+
+### Step 2: Configure 'openmetadata.yaml' or the corresponding environment variables
+
+```yaml
+applicationConfig:
+  logoConfig:
+    logoLocationType: ${OM_LOGO_LOCATION_TYPE:-openmetadata} #either "openmetadata' or { "url" or "filePath" , based on this specify either '*AbsoluteFilePath' or '*LogoUrlPath' }
+    loginPageLogoAbsoluteFilePath: ${OM_LOGO_LOGIN_LOCATION_FILE_PATH:-""} #login page logo , work in "filePath" mode
+    loginPageLogoUrlPath: ${OM_LOGO_LOGIN_LOCATION_URL_PATH:-""} #login page logo , work in "url" mode
+    navBarLogoAbsoluteFilePath: ${OM_LOGO_NAVBAR_LOCATION_FILE_PATH:-""} #nav bar logo , work in "filePath" mode
+    navBarLogoUrlPath: ${OM_LOGO_NAVBAR_LOCATION_URL_PATH:-""} #nav bar logo , work in "url" mode
+```
+1. `logoLocationType` set to 'openmetadata'
+
+   - In this case it will take the default OM logo, we don't need to configure anything else.
+
+2. `logoLocationType` set to 'filePath'
+
+   - In this case it will take the custom logo from the specified absolute paths, need to configure following as well.
+     - `loginPageLogoAbsoluteFilePath` -> This is the path for Login Page Logo Image.
+     - `navBarLogoAbsoluteFilePath` -> This is the path for Navigation Bar Logo Image.
+
+3. `logoLocationType` set to 'url'
+
+   - In this case it will take the custom logo from the specified url, need to configure following as well.
+     - `loginPageLogoUrlPath` -> This is the url for Login Page Logo Image.
+     - `navBarLogoUrlPath` -> This is the url for Navigation Bar Logo Image.
