Customize the WordPress Login Logo and URL Easily

Learn how to replace the default WordPress login logo with your own branding and redirect the logo link to your homepage. This simple code snippet improves your website’s professional appearance, strengthens your brand identity, and creates a more polished login experience without installing additional plugins.

Give Your WordPress Login Page a Professional Look

The default WordPress login page displays the familiar WordPress logo that links to WordPress.org. While this is perfectly fine for a new installation, it does little to promote your own website or business.

If you manage a professional website, client projects, membership platform, or company portal, replacing the default logo with your own brand instantly creates a more polished experience.

The good news is that you don’t need another plugin to accomplish this. With a few lines of PHP code added to your theme or a custom plugin, you can completely customize the login page branding.

This tutorial explains exactly how the code works, where to place it, and how you can safely modify it for your own website.

Why Customize the WordPress Login Page?

The WordPress login screen is often the first page administrators, editors, authors, and clients see before accessing the dashboard.

Replacing the default branding provides several benefits:

Creates a professional appearance
Reinforces your brand identity
Makes client websites look custom-built
Removes unnecessary WordPress branding
Redirects users back to your own website instead of WordPress.org
Improves the overall user experience

Although it doesn’t improve SEO directly, it contributes to better branding and professionalism.

What This Code Does

The snippet performs two separate tasks.

It Replaces the Default Login Logo

Instead of displaying the standard WordPress logo, it loads your own image.

function custom_login_logo() {
    ?>
    <style type="text/css">
        #login h1 a {
            background-image: url('https://wpzone.blog/wp-content/uploads/2026/05/wpzone_icon.png');
            height: 100px;
            width: 300px;
            background-size: contain;
            background-repeat: no-repeat;
        }
    </style>
    <?php
}

add_action('login_enqueue_scripts', 'custom_login_logo');

This function injects custom CSS into the login page.

The CSS targets:

#login h1 a

which is the element containing the WordPress logo.

Instead of the default image, your custom logo is displayed.

How the CSS Works

background-image

background-image: url(...);

Specifies the image that replaces the WordPress logo.

width

width:300px;

Defines the maximum width of the logo container.

height

height:100px;

Defines the height of the logo.

background-size

background-size: contain;

Ensures the entire logo fits inside the container without distortion.

background-repeat

background-repeat:no-repeat;

Prevents the image from repeating.

Redirect the Logo Link

By default, clicking the WordPress logo opens:

https://wordpress.org

Most website owners don’t want users leaving the login page to visit WordPress.org.

This function changes that behavior.

function custom_login_logo_url() {
    return home_url();
}

add_filter('login_headerurl', 'custom_login_logo_url');

Now clicking the logo redirects visitors to:

https://yourwebsite.com

This creates a more professional login page.

Where Should You Add This Code?

There are several safe locations.

Option 1 – Custom MU Plugin (Recommended)

The best solution is placing the code inside:

/wp-content/mu-plugins/custom-login-logo.php

Advantages:

Works independently of your theme
Cannot be disabled accidentally
Survives theme updates
Loads automatically

Option 2 – Child Theme

Add the code to:

functions.php

inside your child theme.

This is a safe option if you already use a child theme.

Option 3 – Code Snippets Plugin

If you prefer not editing PHP files manually, you can use a snippets plugin to insert the code.

Choosing the Right Logo

For the best appearance:

PNG format
Transparent background
High resolution
Landscape orientation
Optimized file size
Sharp edges

Recommended size:

300 × 100 pixels

600 × 200 pixels

for Retina displays.

Using SVG Instead

Modern browsers support SVG images.

Advantages include:

Infinite scaling
Smaller file size
Crisp rendering
Excellent for logos

Example:

background-image:url('/wp-content/uploads/logo.svg');

Responsive Behavior

The code already includes:

background-size:contain;

which makes the logo scale nicely.

For even better responsiveness, you can add:

max-width:100%;

This prevents oversized logos on smaller screens.

Improve Accessibility

To improve accessibility, choose:

high contrast
readable branding
optimized image size
descriptive site title

Avoid oversized graphics that distract users.

Performance Considerations

The login page loads only for authenticated users, so performance impact is minimal.

Still, optimize the image by:

compressing PNG files
using WebP if supported
limiting dimensions
enabling browser caching

A small logo loads almost instantly.

Common Mistakes

Wrong Image URL

Always verify that the logo URL is accessible.

If the image returns a 404 error, the default WordPress logo may still appear.

Large Image

Huge images can look blurry or oversized.

Resize the logo before uploading.

Editing the Parent Theme

Never modify the parent theme directly.

Updates will overwrite your changes.

Incorrect CSS Dimensions

If the width and height don’t match your logo proportions, the image may appear stretched.

Adjust both values accordingly.

Advanced Customization Ideas

You can take the login page even further by adding:

Custom Background

Replace the default gray background with:

gradients
photos
company branding
abstract artwork

Change the Login Button Color

Customize:

background
hover effect
border radius
typography

to match your brand.

Custom Login Message

Display a welcome message such as:

Welcome back to the WPZone Dashboard!

Hide Login Shake Animation

Some administrators prefer removing the default shake effect after failed logins.

Add Dark Mode Styling

A dark login screen looks modern and matches many dashboard themes.

Custom Footer Text

Replace the default footer with:

Powered by Your Company

© 2026 Your Website

Security Considerations

Changing the logo does not improve security by itself.

For better login security, combine this customization with:

Two-Factor Authentication (2FA)
Login attempt limits
Strong passwords
reCAPTCHA
Security plugins
Regular WordPress updates
Firewall protection
Activity logging

Branding and security work well together.

Why Use Code Instead of a Plugin?

Many plugins can customize the login page, but a small code snippet offers several advantages.

Benefits include:

No extra plugin
Faster loading
Fewer updates
Complete control
Lightweight implementation
Easier maintenance
Better long-term performance

For simple branding changes, code is often the cleaner solution.
