Read our full PDF24 Creator review Best free PDF editor onlineįree version only allows for one task each hour And yes, our top choice for best free PDF editor is genuinely free and unlimited, through and through. The interface can feel a little clunky at times, but all of the important features are easy to find and when you first open the software, you’re presented with a grid of editing options. PDF24 Creator has a minimalistic user interface and it’s clear that the program is designed around speed first and foremost. You can even optimize a PDF for the web or apply OCR to a PDF, so that you can convert scanned images to text. The Windows-only tool serves up a PDF editor for free document creation, PDF merging, PDF compressing, and converting PDFs into other formats. While we noted that it lacked more advanced features usually found in premium tools like Adobe Acrobat DC, we felt that most users will find more than enough utility within PDF24 Creator. It’s full of features, and has everything needed to create and edit PDF documents. When we tested the software, we rated it as one of the best free tools, going above and beyond what's expected. The free PDF editor is a very small program that can easily run on older systems - ideal, then, for businesses with limited resources or a suite of low-spec computers.
