Fox it Reader (it is very good in the right conditions, but I find the ads intrusive in the settings page), I used Google's PDF Wrangler a lot. It is free and can convert most of the PDFs I was using to other formats (and even convert them to image files!) without the need for any plugins. It also makes the process of making a PDF more pleasant. I used it for a while and liked it very much. I switched to Microsoft's Fox-It Reader and it is very good, especially if you don't need the many features the other one offers (but, as I said, I think it's a little overkill on a phone.) Fox Reader also provides a lot of PDF exporting functions. The only downside of Fox-It is that it doesn't include features that can be found only in Windows apps, and I'm afraid that it's also not portable. But, if you don't use Windows anyway, it is a great free PDF editor. Also, Fox Reader is one of the few online tools that integrates with the Adobe Acrobat Pro program. The other ones, like Scrivener for instance, are very good but require Adobe plug-ins or have limited functionality. I hope, some day, that Adobe will finally develop a new application that allows you to use all of these things with their apps (which for many users are a better, more convenient and more flexible approach than opening a PDF files). Fox reader does not, and I feel it's a shame to lose an app on which a big part of my day would depend. Fox Reader Jul 27, 2023 — The biggest competitor to Acrobat for Windows... the Amazon.com Reader. It's Amazon's latest effort at becoming an online distributor to its bookstores. The company said Thursday that it will launch an online PDF product in 2018, and Amazon Prime is free at the time of writing for all readers. Amazon customers will have to sign up for its free 30-day trial. This isn't Amazon's first foray into online PDFs; last year it launched an instant PDF reader called Kindle Keyboard PDF, as well as a standalone “Kindle App” that integrates with the Amazon Prime service. Still, I can't bring myself to be optimistic about an online PDF reader.
