Size Limit for Uploading Files Through cPanel File Manager or PHP
All shared, reseller, and semi-dedicated hosting plans have a maximum request size of 500 MB. This value cannot be modified or increased. This means you will be unable to upload any file larger than 500 MB through cPanel’s File Manager or a PHP-based upload form.

Section titled “Uploading Larger Files”For files exceeding the 500 MB limit, use FTP or SFTP instead:
We recommend FTP or SFTP for uploading files as a general best practice, as they are faster and more reliable than any web-based upload method.
