Best fillable PDF creators compared

12 tools that add form fields to a PDF, compared on how they place fields, what the free tier allows and what paid access costs.

Facts were read from each vendor's own pages in October 2026. JustFill is our product and is listed first, with its limits. Prices change, so check before you buy.

How to choose

Where your PDF starts

If the PDF is a flat scan or a photo, a tool that proposes fields for you saves the most time. If you build a form from scratch, manual field placement is enough.

How often you do it

One form once is a job for a free tool or a one-time pass. A form you prepare for many clients or fill many times is worth a plan that keeps your layout.

What the free tier really allows

Free plans differ in file size, page count, number of tasks per hour and whether form fields are included at all. Check that before you build the whole form.

Who has to fill it

Real form fields work in Acrobat Reader, browsers and phones. If your recipients only use a browser, test the finished file there before you send it.

The comparison

Where JustFill fits, and where it does not

JustFill suits you when the PDF starts flat or scanned and you want fields placed for you, when you reuse the same layout for several clients, or when you fill many copies from an Excel or CSV file.

It is not the cheapest route for one simple form you are happy to build by hand, and field detection is probabilistic, so you review the result. If you only need a basic form once, a free tool above may be enough.

Read the step-by-step guide to making a PDF fillable for the methods side by side, or go straight to the tool page.

Frequently Asked Questions

It depends on where your PDF starts. For building a basic form by hand, LibreOffice, PDFgear and PDFescape cost nothing. For a flat or scanned PDF where you want fields placed automatically, compare the free tier of the tool that offers detection, and check its limits before you start.
No. Several browser and desktop tools add real form fields without Acrobat. Acrobat remains the reference tool for advanced forms and accessibility work, and it is paid.
Often yes for a single form. Free versions limit file size, pages, tasks per hour or the form features, so a form with many pages or a form you reuse every week usually outgrows them.
