Gravity PDF vs PDF.js Viewer

Gravity PDF is the ultimate third-party PDF automation tool for generating digital PDFs using the popular form-builder plugin Gravity Forms. Highly Customizable PDFs Out of the box you get four highly-customizable PDF designs. Within minutes, you can personalize the look and feel by adding your company logo, header, footer, paper size / orientation, font, color and size. If the free designs don’t suit, select from our range of templates in the Template Shop, go bespoke and have a template build by our team, or build your own using HTML/CSS/PHP. Send as Email Attachment Gravity PDF can automatically email the PDF to both the admin and the user as soon as the form is completed. You can combine this feature with a Gravity Forms payment add-on to sell personalized reports, gift certificates, or generate PDF invoices. Privacy, Security, and GDPR Gravity PDF generates PDFs on your web server, and no third-party service receives your sensitive Gravity Forms entry data. Robust security protects your documents, and the plugin is GDPR-compliant for our European friends. Digital document management with WordPress and Gravity Forms just became simple with Gravity PDF! Free Feature Unlimited Use, No Restrictions – There are zero hard limits to the number of PDFs you can configure across all your forms or generate on your entries. Gravity PDF does NOT stamp documents with our logo, limit the number of PDFs you can create per month, or purposefully restrict essential functionality to force you to upgrade to a paid plan. Privacy and Security – your form data is never sent to a third party to generate the PDFs and the documents are generated directly on your web server. Strong access control policies are put in place to prevent unauthenticated access to your PDFs. Multilingual – a multitude of languages from across the globe can be displayed in PDFs, include complex scripts like Hebrew, Arabic, Thai, Japanese, Chinese, and Korean. Additional Fonts – match your branding and enhance the overall look and feel of PDFs by install your own fonts. Columns – use Drag and Drop columns in Gravity Forms and PDFs will automatically mimic that layout. Shortcode and Merge Tags – You can generate a link or URL to PDFs using both shortcodes and merge tags so your users can download the PDF right after form submission. Export Entries – include the direct link to any PDF(s) when exporting your form entries Webhooks Add-on – send the direct PDF link with Webhook requests when using Gravity Forms Webhooks add-on. Gravity Flow – create complex workflows using Gravity Flow and automatically email Gravity PDF-generated documents at any step in the workflow. GravityView – add links to PDFs when building a members area using GravityView + Advanced Filtering add-on. Background Processing – generating PDFs on form submission can be time consuming. Offload it to a background process will ensure form submissions are processed faster. Design PDFs – developers can build their own PDF templates using HTML, CSS, and PHP with the help of our developer documentation. Documentation and Support – there is extensive documentation covering every feature of Gravity PDF that you can comb through, plus we provide free general support to all users. Unlock More Functionality Pay for additional PDF designs and functionality from our online store. New Designs – get access to 9 additional universal designs, 6 certificates, 6 invoices, and 3 letter styles Additional customizations – watermark PDFs with your own logo or text, control fields that should be displayed per PDF, add field descriptions, display all checkbox or radio field options, add notes, show field values instead of labels, and hide the product table On-screen Preview – allow users to preview the PDF before form submission (and optionally payment) so they can see what the end result will be. This is a great feature for capturing e-signatures, selling PDF reports / certificates / gift cards, or providing an on-screen proof before the PDF is sent to the printers (perfect for business cards). Bulk Download – search, filter, and select entries and then zip up all your PDFs and download all together in a convenient zip file Smart Loading Indicator – improve the UX for your users when generating complex PDFs that take time to create. GravityView – turn GravityView into a drag-and-drop PDF builder for your Single Entry View Layouts.
