Introduction

The upload_max_filesize directive in PHP controls the maximum size of files that can be uploaded to a server. In a cPanel environment, this limit is important for websites that handle media uploads such as images, videos, backups, or large documents. If the limit is too low, users may encounter upload errors. cPanel provides easy tools to modify this setting without needing deep server-level configuration changes.

Prerequisites

Before changing upload_max_filesize, ensure the following:

• Access to cPanel account (or WHM if you manage multiple accounts)
• PHP version in use supports configuration changes (PHP 5.x and above)
• Permission to modify PHP settings via MultiPHP INI Editor or .htaccess (if applicable)
• Awareness of related limits such as:
  • post_max_size
  • memory_limit
• Backup or note of current PHP configuration (recommended)
