Generate PDFs with Fillable Form Fields from HTML
With our API, you can generate PDFs that include interactive fillable fields directly from your existing HTML input elements. Our API supports most of the standard HTML input types and a custom <pdfgate-signature-field /> tag for creating digital signature fields. You can also customize the appearance and behavior of each field using PDFGate's custom HTML attributes.
This guide explains how to add fillable form fields to your PDFs and provides code examples so you can quickly integrate them into your workflow.
The feature is available directly on our HTML to PDF generation endpoint. You simply have to include the enableFormFields parameter in your request, and the API will automatically generate your PDF with all of your specified interactive form fields.
