In Magento, there is no setting to change Magento’s backend logo.
For that, first, you need to create a custom admin theme and then change the logo.
Steps are listed below:
- app/code/[VendorName]/[ModuleName]/registration.php
MagentoFrameworkComponentComponentRegistrar::register( MagentoFrameworkComponentComponentRegistrar::MODULE, '[VendorName]_[ModuleName]', __DIR__ ); - app/code/[VendorName]/[ModuleName]/etc/module.xml
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="[VendorName]_[ModuleName]" setup_version="1.0.0"> <sequence> <module name="Magento_Theme"/> </sequence> </module> </config> - app/code/[VendorName]/[ModuleName]/etc/di.xml
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <type name="MagentoThemeModelViewDesign"> <arguments> <argument name="themes" xsi:type="array"> <item name="adminhtml" xsi:type="string">[VendorName]/[themename]</item> </argument> </arguments> </type> </config> - app/design/adminhtml/[VendorName]/[themename]/registration.php
MagentoFrameworkComponentComponentRegistrar::register( MagentoFrameworkComponentComponentRegistrar::THEME, 'adminhtml/[VendorName]/[themename]', __DIR__ ); - app/design/adminhtml/[VendorName]/[themename]/theme.xml
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd"> <title>Theme Title</title> <parent>Magento/backend</parent> </theme> - app/design/adminhtml/[VendorName]/[themename]/Magento_Backend/layout/admin_login.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-login" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <update handle="styles" /> <body> <referenceBlock name="logo"> <arguments> <argument name="logo_image_src" xsi:type="string">images/login-logo.svg</argument> </arguments> </referenceBlock> </body> </page> - Upload
app/design/adminhtml/[VendorName]/[themename]/web/images/login-logo.svg - app/design/adminhtml/[VendorName]/[themename]/Magento_Backend/layout/default.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <body> <referenceContainer name="header"> <referenceBlock name="logo"> <arguments> <argument name="logo_img_width" xsi:type="number">300</argument> <argument name="logo_img_height" xsi:type="number">300</argument> <argument name="show_part" xsi:type="string">logo</argument> <argument name="edition" translate="true" xsi:type="string">Community Edition</argument> <argument name="logo_image_src" xsi:type="string">images/menu-logo.svg</argument> </arguments> </referenceBlock> </referenceContainer> </body> </page> - Upload
app/design/adminhtml/[VendorName]/[themename]/web/images/menu-logo.svg - Magento CLI
php bin/magento setup:upgrade php bin/magento setup:di:compile
Note: You can change the names of logo files in the configuration file if you want to use PNG files instead of SVG for the logo.
