The maximum file size for uploads from your submission form can vary from web host to host.
If a customer tries to upload a file that exceeds your servers maximum file size limit, they will be presented with an error and the form will not be submitted.
If you are not comfortable with making configuration changes to your web server, you should contact your host for assistance before proceeding.
The file size limits are generally managed within your php.ini file and specifically by three options within that file:
Determines the maximum size of a file that can be uploaded
Determines the maximum size of the data that can be posted from a form. Must be higher than upload_max_filesize. If multiple file uploads are allowed, should be higher than the combined upload_max_filesize for all files
Can also impact file uploads and should be set to higher than post_max_size
Once you have edited your php.ini file and set these options to your preferred values, you will need to restart your web services.
