How to Increase PHP Max Upload File Size in cPanel & WHM (Complete Guide)

PHP is a vital component of web hosting, but its default file upload size is often too low for modern websites. If you’ve encountered an error asking you to increase the PHP max upload file size, don’t worry! This guide will show you how to adjust PHP upload limits in cPanel and WHM quickly and efficiently with HosterSale’s optimized hosting solutions.

What is “upload_max_filesize” in PHP?

The upload_max_filesize directive in PHP controls the maximum file size that can be uploaded to your web hosting server. By default, PHP sets this limit to 2MB, which is insufficient for most users. To allow larger file uploads, you must modify this value.

Other PHP Settings You Must Adjust:

• post_max_size – Should be larger than upload_max_filesize to accommodate form submissions.
• memory_limit – Should be higher than post_max_size to avoid memory issues.

PHP File Size Units:

• K = Kilobytes (e.g., 500K = 500 KB)
• M = Megabytes (e.g., 100M = 100 MB)
• G = Gigabytes (e.g., 1G = 1 GB)
