#2: Xodo [iOS, Android, Windows, Web]

Xodo is a very popular mobile and desktop app (Windows only) that's been around for a while. The online or web version has been rebranded to PDF.online but the service is essentially unchanged. Strictly speaking, Xodo is not a PDF editor but rather an annotation tool. The ‘editor' tag comes from its ability to fill forms, sign them, annotate files, and generally manage PDF files. The online utility goes a step further, allowing you to mark content for redaction, but you can't edit or delete existing content in a PDF. The reason we've added this family of PDF tools to this list is that it is free to use and pretty handy when all you need are some form-filling features, PDF signing, viewing and annotating PDF and Office files, adding blank pages between sections of a PDF, and so on. Moreover, since it's a cross-platform family of applications, you can use Xodo on the web, on your mobile devices, and on Windows as well. There's no Mac version but macOS users can opt for the online service for their PDF needs.

Xodo Feature Highlights

● View, Read, Annotate PDF and Office files.

● Add blank pages or insert from your camera or Photo app.

● Dark Mode support on iOS.

● Fill forms and apply electronic signatures.

Price: Free to use.

Smallpdf is a powerful PDF utility with annotation tools, extensive support for file conversions, and other useful features for PDF protection, page management, PDF signing, etc. All the versions of Smallpdf pretty much offer the same feature set but for different platforms. For instance, you can convert various file types to PDF or convert PDF to other formats, compress files, organize pages, apply page numbering, protect and unlock PDFs, and so on.

That means Apple device users will find the apps easy to use and simple to learn with respect to various PDF tasks. Also on the plus side is the fact that PDF Expert is a ‘true PDF editor', which means you can modify and delete existing text, edit images, and perform other editing actions, and this is possible on both the Mac version as well as the mobile version for iPhone and iPad devices. Overall, PDF Expert brings a lot of value to users with its rich editing, annotation, conversion, and other features, as listed below.

#5: Preview App [Mac Only]

You've probably used Preview to open images files such as JPGs and PNGs, but did you know that Preview is also a powerful PDF utility for annotation and conversion to other formats? The tools are limited and there's no true PDF editing possible with Preview, but when you need to markup a document or convert it into a different file type, Preview can come to your rescue. Since it's a native Mac app that's specially designed for the macOS environment, the UI is very intuitive and user-friendly, which means there's no steep learning curve when you first start using these applications.

How to Choose the Best PDF Editor App for You

There are a lot of different aspects to be aware of when choosing the best PDF editor for your specific needs. For instance, if you only work on one platform and your requirement is limited to annotating and sharing PDFs, then iAnnotate might be the best PDF editor for you. On the other hand, if you want robust functionality, rich features, accurate conversion, and availability on multiple platforms, then PDFelement is the obvious answer.

Incidentally, PDFelement can be used for free without any feature restrictions, with the only caveat being that a watermark will be added to files that are processed and saved in this set of apps. But if you choose to upgrade, you'll be paying as little as $6.99 a month for the Standard version of the PDFelement PDF editor, which is just a little more than half of what you'd need to pay for a subscription to an expensive tool such as Adobe Acrobat DC.
