For Individual Users: Easy-to-use Desktop & Online PDF Form Fillers
If you're a student, freelancer, admin staff, or just someone who occasionally needs to fill out PDF forms, such as W2, W4, or W9 tax forms and passport forms, you likely want a solution that’s fast, simple, and budget-friendly.
We evaluated both online tools and desktop software, and selected the top 2 from each category:
1. Best Online PDF Form Fillers
PDFfiller
As a free online PDF form filler, PDFfiller stands out with its massive template library (over 10 million forms), allowing you to search for ready-to-fill documents like passport form fillers or IRS tax forms. And its interface is clean and intuitive, perfect for quick, no-hassle form filling.
DocFly
DocFly is another free PDF form filler online, which lets users fill out, sign, and even create forms. You don’t need an account, but keep in mind: you can only export 3 PDFs per month for free. Great for one-off needs, but not ideal for frequent form filling.
2. Best Desktop PDF Form Fillers - Free
PDF Reader Pro - Free
PDF Reader Pro is a reliable and free PDF form filler for desktop, which offers robust form filling, editing, and signing features on both Windows, Mac, iOS, and Android. It’s ideal for users who prefer working offline or need a stable tool without complex licensing requirements.
Adobe Acrobat
Famous in the PDF world for a long time, Adobe Acrobat offers a comprehensive form filling experience. However, it requires a paid subscription and is known for frequent login prompts and online issues. That said, if you're willing to pay, it’s powerful and highly polished.
For Businesses: Enterprise-Level PDF Form Fillers
Organizations—from HR departments to legal teams—often deal with bulk form filling, employee onboarding, and document review workflows. If you’re managing multiple users, looking for admin controls, or need secure deployment, these enterprise PDF tools are worth exploring:
1. LynxPDF – The Best PDF Form Filler for Teams
Designed specifically for teams and organizations, LynxPDF is a modern solution tailored to business needs. It supports seamless form filling, annotation, and editing while offering:
-
Advanced admin console tools

Secure deployment options (on-premise or cloud)

2. Adobe Acrobat for Teams
Adobe's enterprise version allows integration with Microsoft 365, SharePoint, and other business tools. While it's highly reliable and full-featured, the monthly subscription costs can add up—especially for large teams. It's your solid choice if the budget is no issue.
3. Nitro PDF for Business
Nitro offers all the basic form filling, collaboration, and PDF editing tools. It’s affordable and easy to use, making it suitable for small to mid-sized teams. However, it lacks features like advanced admin control or on-premise deployment, which may limit scalability.
