Looking for the best free PDF editor? You’re in the right place. 

PDF (Portable Document Format) is one of the most valuable file formats in existence. You can manage everything from professional, high-quality invoices to employee contracts through a PDF. The format is extensively used in various industries, including legal, real-estate, medical, and education. 

Compared to other formats, PDF offers the following benefits:

  • Preserve format: PDFs display exactly how you lay them out no matter what device or program you’re using to view them. 
  • Save storage: The PDF file format allows you to compress relatively large file sizes KBs, making it easier to save on storage space. 
  • Legally binding: The PDF is the only file format that can accommodate e-signatures for a document to be legal and binding. 

The downside of PDF is that it doesn’t let you edit text or replace other elements easily. For that, you need a PDF editor. Unfortunately, because Adobe (the original creators of the PDF) still owns certain technologies associated with the format, it isn’t always easy to find tools to edit PDFs.

That’s why we’ve put together this article to help you discover the best free PDF editor software available right now. 

Don’t wait for someone else to do it. Hire yourself and start calling the shots.
