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 just started using this form and am still getting use to it. im sure if you ask me next week it will be 5 stars for sure

What do you like best?
I can send as many documents out for signature as I want. No restrictions. I used to use Adobe, but they had a cap on the amount of documents you can send for signature. When I tried to get that upgraded, they had outlandish prices for this same service. With PDFfiller, I can send all the documents I want and I'm also able to save all of them securely.
What do you dislike?
I wish the PDF conversions didn't come out like pictures. When I convert a PDF to Word, it always comes into Word as a picture instead of being able to edit the document. As a recruiter, I receive a lot of resumes that need some work before we can submit them to clients. I still have to use Adobe for this function, so now I'm paying for two PDF programs. I can't just stay with Adobe though because of the above mentioned issues.
Recommendations to others considering the product:
If you need eSignatures, this is the program to go with.
What problems are you solving with the product? What benefits have you realized?
Remote onboarding is a breeze with PDFfiller. I am able to send HR documents to people across the country and still get them to work on time. I'm in VA and have to get employees to work in all states across the country, as well as oversees. We have to get documents to them for signature and faxing doesn't always work. With PDFfiller, we can send anyone any document and get it back fully signed by them. It's truly wonderful.
