--- title: "Admin Customizer for Joomla, Brand Your Backend & Login Page" date: 2026-07-18 author: "Jeroen Moolenschot" --- # Admin Customizer for Joomla, Brand Your Backend & Login Page # Make the Joomla admin yours Admin Customizer restyles your entire Joomla backend and login page from a single brand color. No CSS required. Unlimited sites. - - [Documentation](https://www.joomill-extensions.com/documentation/admin-customizer-plugin) ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-default.png) ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-customized.png) - Joomla 5 and 6 - Unlimited installations - Light & dark mode Every Joomla site ships with the same blue admin. Your clients log into it every day. Admin Customizer turns that generic backend into a branded workspace, without touching a template or writing CSS. Change one color and watch the header, sidebar, buttons, tables and login page follow. ## What your admin could look like Every screen below is the same Joomla backend, styled with nothing but plugin options. Pick a brand color and build your own look in minutes. ### Login screen examples - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-04.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-08.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-03.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-01.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-06.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-05.png) ### Admin screen examples - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-02.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-06.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-04.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-05.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-03.png) - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-01.png) ## Everything it restyles Deep propagation across the whole backend, not just a header color. ### One color drives everything Pick a brand color and Admin Customizer recolors the whole backend: header, sidebar menu, primary buttons, links, table accents, tabs, dropdowns and even form checkboxes. Text contrast is calculated automatically, so a light sidebar never leaves you with unreadable white labels. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-04.png) ### A branded login page The login screen is the first impression. Set its logo, colors, background image and fonts independently, or let it inherit your brand automatically. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-04.png) ### Dark mode that behaves By default Admin Customizer leaves Joomla's dark mode exactly as it is. Turn on Custom Dark Mode Colors and your brand takes over the dark theme too,fully and consistently. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-darkmode.png) ### Fonts, hosted locally for GDPR Choose any Google Font for headings and body text. Admin Customizer downloads the font to your server once, so your visitors' browsers never contact Google. GDPR-friendly out of the box. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-google-fonts.png) ### Radius & shadow presets Round the corners and add depth to buttons, inputs, dropdowns and panels with ready-made presets, or dial in your own. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-border-radius.png) ### Logos and backgrounds Swap the admin and login logos, add a background image or color to the main area and sidebar, with separate light and dark logo variants. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/login-screen-07.png) ### Import & export your own presets Style one site, export the settings to a file, and import them on the next site in one click. Build your own library of looks and reuse them across every project. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-importexport.png) ### Custom CSS/JS for the last 5% Need something specific? Add scoped custom CSS or JavaScript per color mode, without editing template files. ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-screen-customcode.png) ## Branded in three steps - ![](https://www.joomill-extensions.com/images/documentation/general/install-02.jpg) Install the plugin and enable it - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/step2.png) Open the plugin, pick a brand color and edit the settings - ![](https://www.joomill-extensions.com/images/extensions/admincustomizer/admin-customized.png) Save.

No. Everything is done with color pickers and options. Custom CSS is available if you want it, but never required. - ### On how many sites can I use it? As many as you like. One purchase covers unlimited installations. - ### Will it break my admin or template? No. Admin Customizer layers on top of Joomla's Atum template using CSS variables. Disable the plugin and everything reverts instantly. Dark mode is left untouched unless you explicitly enable custom dark colors. - ### Does it work with Joomla 5 and 6? Yes. - ### Are the Google Fonts GDPR-compliant? Yes. Fonts are downloaded to your own server once and served locally, so no visitor data goes to Google. - ### Can I move my styling to another site? Yes. Export your settings to a file and import them on any other site in one click, so you can reuse the same look across all your projects. - ### Is this a subscription? You pay once and the plugin keeps working forever. Your purchase includes one year of updates and support; after that you can optionally renew to keep receiving updates. - ### What exactly can I style? Header, sidebar menu, main area, login page, logos, backgrounds, buttons, links, tables, tabs, dropdowns, form controls, fonts, border radius and shadows, in both light and dark mode. ## Stop shipping the default blue admin One brand color restyles your whole backend and login page on unlimited Joomla sites. - - One license, unlimited sites · Personal support from the developer ## Custom Fields **Extension Name:** Joomill Admin Customizer plugin **Extension Alternative Name:** Joomla Atum Customizer plugin **Cache Key:** admincustomizer **OCH categorie:** 25 **Prijs PRO versie:** 20 **Extension URL:** https://www.joomill-extensions.com/extensions/joomill-admin-customizer **JED URL:** https://extensions.joomla.org/extension/admin-customizer/ **Extension Download URL:** https://www.joomill-extensions.com/downloads/admincustomizer **Buy Now URL:** https://www.joomill-extensions.com/buynow/admincustomizer
