Gravity PDF Requirements and Detailed Installation Instructions

Plugin Requirements

Gravity PDF can be run on modern shared web hosting providers, and the easiest way to check if your host can run it is to install the plugin. Gravity PDF has checks in place when you first activate it on your WordPress website, and it will let you know if there are any issues than need addressing.


While Gravity PDF is a free plugin, it requires Gravity Forms to run. You'll need to purchase a Gravity Forms license before you can use Gravity PDF – any license type will work.


Gravity PDF is a third party extension for Gravity Forms, created by an independent company who love how powerful the software is. We have no control over their pricing model, and we do not provide direct support for their software.

Software Requirements

Server Requirements

  • PHP 7.3+
  • MB String with Regex enabled (--enable-mbregex)
  • GD Library
  • DOM
  • allow_url_fopen (optional) - If you have image display problems make sure this option is enabled.
  • 128MB+ WP Memory (256MB+ recommended)

If you are unable to meet the v6 minimum software requirements, Gravity PDF will continue supporting users on v5 with bug and security fixes until at least 27 April 2023.

Manual Installation

You can manually install the plugin by downloading the plugin zip file from and then uploading through your WordPress admin area. The plugin zip file is 4.2MB and most web hosts maximum upload limit should be higher than this (you can check your maximum upload limit by navigating to Media -> Add New in your WordPress admin area and reviewing the Maximum upload file size limit).

FTP Installation

Upload the Gravity PDF plugin files to the WordPress plugins directory using your favourite FTP client.

  1. Go to the plugin's WordPress repository and select the Download Version 6.x.x button.

  2. Once downloaded, unzip the plugin folder. A folder called gravity-forms-pdf-extended will be extracted and this is what you should upload to your FTP server.

  3. Open your favourite FTP client (we recommend Filezilla) and enter your hostname, username and password. If you are unsure where to get these details, you should contact your web hosting provider for assistance.

  4. Once logged in, navigate to your WordPress plugin directory (usually /wp-content/plugins/) and upload the gravity-forms-pdf-extended folder. If a directory called gravity-forms-pdf-extended already exists, delete it before uploading. Upload plugin via FTP
