Our Verdict

A complete online PDF toolkit — fill and create forms, edit, convert, and add legally-binding e-signatures from any browser.

Best for: Anyone who works with forms, contracts and e-signatures.

pdfFiller is built around the thing most people actually struggle with: forms. It makes filling, creating, and managing fillable PDFs genuinely easy, and its e-signature tools are legally binding — handy for contracts and onboarding paperwork.

Because it's fully cloud-based, it works from any browser or device, and it ships with a huge library of ready-made templates you can search and edit.

You'll need a subscription to get the most out of it, and the feature-packed interface takes a moment to learn. But for form-heavy and signature workflows, it's one of the most capable tools available.

Pros

  • Powerful form filling & creation
  • Legally-binding e-signatures
  • Huge searchable form library
  • Cloud-based — works on any device

Cons

  • Subscription needed for full use
  • Interface can feel busy
