The Best Free PDF Tools in 2024

PDFs are everywhere — invoices, contracts, resumes, academic papers. But not all PDF tools are created equal. Some limit file sizes, others watermark your documents, and many upload your files to remote servers where you have no control.

This guide compares the best free PDF tools of 2024 across four key criteria:

• Privacy — Do files stay on your device?
• Features — What can you actually do?
• Limits — File size, page count, daily usage
• Ease of use — How fast can you get results?
