How do I write on a PDF without Adobe?
There are many options that let you write on a PDF without using Adobe. One option is the QuillBot PDF editor. It’s an online tool that works across multiple platforms, browsers, and operating systems and on desktops, laptops (Mac and PC) and mobile devices (iOS and Android).
Once you’ve uploaded your document, you can add highlighting, text boxes, drawings, or images. Then you can save or print your document as you wish.
