How to fill or build a PDF form

1. Upload or create your form

Everything you need to work with forms

  • Make any PDF fillable in seconds Upload any static PDF, from scanned forms to tax templates, and turn it into an interactive form. Add text fields, checkboxes, dropdowns, date pickers, and signature fields anywhere on the form. No redesign. No extra tools needed.
  • Build forms from scratch or let AI do it Start from a blank page, pick a template from pdfFiller's library, or describe what you need and let AI generate a ready-to-use form in seconds. Add fields, set validation rules, mark required inputs — then publish, embed, or share in one click.
  • Fill any form online pdfFiller auto-detects fillable fields as soon as you open a document. Just click and start — type text, check boxes, pick dates, or add your signature. No downloads or extra tools. Works with scanned PDFs and non-interactive forms too.
  • Collect responses, not just files Share your form via a direct link, embed it on your site, or send it to specific recipients. Every submission lands in your pdfFiller account as a separate, trackable response. See who completed the form, get notified when new responses come in, and export all entries to a spreadsheet in one click.
  • Reuse your forms without starting over Save any form as a template and reuse it whenever you need. When the same intake form, contract, or questionnaire needs to go out again, just open the template, update what’s changed, add a signature, and send. Each submission is saved separately, so your original stays intact.

I had to use pdf Filler to fill out some online divorce documents, and after being initially upset at having to pay for a monthly subscription for a year to print it (very upset), I sucked it up, signed up, and have never stopped using it. Just discovered the eraser...very cool.

I am trying to figure out if I can save a pdf and than save it again under another name. Not knowing this is frustrating

Hard to get used to, and probably a lot of features we are not taking advantage of for lack of know-how, but very reliable and handy. We mostly use it to send for signature.

This is a great programme This is a great programme - but as an individual, probably not quite what I wanted as it is a bit expensive for the odd document.
