Fill PDF Service

Fill PDF Service is an iText and pdftk web service which lets you:

  1. Populate an existing PDF template with webform data
  2. Parse PDF documents, allowing you to interpret a template's form-field structure

This can be useful, for example, if your website is similar to TurboTax or FAFSA, where a user is guided through webforms whose data will later populate a PDF template. If you're trying to do this kind of PDF crunching in an application built on PHP (such as Drupal), this service might be for you (see why).
