How to Secure WordPress Media Files (Images, PDFs, Videos) – A Complete Guide

Secure WordPress Media Files

WordPress makes uploading and managing media files incredibly easy. Images, PDFs, videos, audio files, and other assets are stored in the wp-content/uploads directory and can be accessed directly via URL.

While this convenience is great, it also introduces a security risk: to secure WordPress Media Files, anyone who knows the file URL can access your media by default, even if the content is meant only for members, customers, or logged-in users.

In this detailed guide, you’ll learn:

  • Why WordPress media files are not secure by default
  • Common security risks related to media files
  • Multiple methods to secure WordPress media files
  • Code-based and plugin-based solutions
  • Best practices for different use cases (membership sites, LMS, downloads, private files)

Why WordPress Media Files Are Not Secure by Default

WordPress Plugins for Social Media Sharing

By default, WordPress stores media files in:

/wp-content/uploads/

These files:

  • Are publicly accessible
  • Do not require authentication
  • Bypass WordPress permission checks

Example:

https://example.com/wp-content/uploads/2025/01/private-document.pdf

Even if that PDF is linked inside a password-protected post, anyone with the URL can still access it.

Common Security Risks of Public Media Files

1. Unauthorised Access

Private documents, invoices, course materials, or client files can be downloaded without permission.

2. Content Scraping

Images and videos can be hotlinked or scraped by other websites.

3. Data Leakage

Sensitive PDFs (contracts, reports, personal data) can be exposed to search engines.

4. Bandwidth Theft

Hotlinking images or videos can significantly increase server load.

When Should You Secure Media Files?

You should secure WordPress media files if you are running:

  • Membership websites
  • Online courses (LMS)
  • Client portals
  • Download-based products
  • Private documentation or resources
  • Paid communities

If your site is purely a public blog or portfolio, media security may not be critical.

Method 1: Block Direct Access Using .htaccess (Apache)

This method prevents direct access to media files and allows only WordPress or PHP scripts to serve them.

Step 1: Create a Protected Uploads Folder

Move sensitive files to a custom directory, for example:

/wp-content/protected-uploads/

Step 2: Add .htaccess Rules

Create a .htaccess file inside the folder:

Order Deny,Allow

Deny from all

This blocks all direct access.

Step 3: Serve Files via PHP

function serve_protected_file( $file_path ) {

    if ( ! is_user_logged_in() ) {

        wp_die( 'Unauthorized access' );

    }


    if ( file_exists( $file_path ) ) {

        header( 'Content-Type: application/octet-stream' );

        header( 'Content-Disposition: attachment; filename="' . basename( $file_path ) . '"' );

        readfile( $file_path );

        exit;

    }

}

Pros

  • Strong protection
  • Full control

Cons

  • Not beginner-friendly
  • Can increase server load

Method 2: Secure Media Using WordPress Hooks (Advanced)

You can intercept file requests and check permissions.

Example: Restrict PDF Access

add_action( 'template_redirect', function () {

    if ( strpos( $_SERVER['REQUEST_URI'], '/wp-content/uploads/' ) !== false ) {

        if ( ! is_user_logged_in() ) {

            wp_die( 'You must be logged in to access this file.' );

        }

    }

});

This approach is not recommended for large sites as it impacts performance.
