Today there are plenty of free PDF programs that can:

  • ✏️ Edit text and images in a PDF
  • ➕ Merge multiple PDFs into one
  • 🔄 Convert PDFs to Word, images, or other formats
  • 🔐 Protect or remove passwords
  • 🧩 Fill forms and add signatures

Here are our top picks for 2025—for both Windows and browser.

Smallpdf offers 20+ PDF tools directly in your browser, including:
