There are quite a few good online PDF editors that are free. A few I can recommend are. What I’ve realized, though, is that some apps will be really good in one area but lacking in another. Some apps might be great for collaboration but not so good for editing. Some only work on Windows while some are designed exclusively for Mac and iOS. Some are just limited in their features. I have honestly found the best free online PDF editor to be Kdan PDF Reader. I really like its functionality and simplicity. It makes editing, converting, and creating PDFs really efficient. PDF Reader is free and works on Android, iOS, MAC, and Windows which makes switching between mobile, PC, and MAC easy. It really has the most editing features I’ve seen in a PDF editor. There are also other great features that make it an enjoyable experience for me like working with audio and video files. It automatically syncs with your Kdan Cloud which helps with organization and accessibility. Check out those editors I mentioned in the list above and see what works best for you. I hope you find one you like! Disclaimer. I am part of Kdan’s team and my answers might be a bit biased.
I am very passionate about supporting open source. I also love coding, so I’m always working on new technology. I believe that open source software is not just the future of technology it is also the future of our digital lives. As an open source advocate and blogger, I would love you to use and support this software. I also really want the experience to be as enjoyable as possible. Dan may not be for everyone.
