PDF readers have always been a pretty tricky niche. Either they are used in work environments to create and fill out forms, or we use them to read ebooks on the tablet. In either of the 2 cases, many times this type of apps end up giving more problems than anything else. Today, we review the best PDF readers (and editors) for Android available on Google Play, plus a few ebook readers in EPUB format.
Top 10 PDF Readers and Editors for Android in 2020
In the following list, we include Best PDF Viewers - Lightweight, Ad-Free, Fast & Free Readers. Not all meet all these conditions - you know, quality, as in almost everything, is paid at a good price - but without a doubt, they are the best we can find to read scanned documents, books, notes and others on mobile devices and tablets.
Adobe Acrobat Reader
Definitely, Adobe's Acrobat Reader is the most popular PDF reader, both on Android –more than 100 million downloads- and on desktop computers. Among its features, we find the possibility of taking annotations in PDFs, filling in forms and adding our signature.
It also has support for Dropbox and Adobe Document Cloud. The paid subscription offers additional features, such as the ability to export documents to many other formats.

Foxit Mobile PDF is an excellent PDF reader that allows us to perform a lot of actions. We can open normal or password-protected documents, and it offers support for adding bookmarks. We also have annotations, with which we can highlight and underline texts.
Although it is an excellent reader for tablets, it adapts quite well to small mobile screens, thanks to the custom text reshuffling and redistribution. It also has a premium version that offers additional features, such as the ability to edit text and images in any PDF document.

Xodo PDF Reader & Editor
Normally, if we look for PDF readers in the Google store, we will almost always find quite basic applications, which allow us to view documents and little else. Xodo, on the other hand, comes loaded with a sea of possibilities.
We can create new PDFs with the camera, from images or Office documents. It also allows you to fill out forms, rotate files, underline text, and add annotations. It offers support for Google Drive, Dropbox and OneDrive: all with the possibility of synchronizing the documents we are editing with the source file, to always be 100% updated.

Speaking of free and lightweight readers, we cannot bypass the Google PDF viewer. Like the rest of the company's office applications, it is integrated with Google Drive, as well as Google Docs, Spreadsheets and Presentations.
It's a very basic reader, but with some pretty cool features. We can search for words or phrases within the document, copy text and send to print (if necessary). As we say, it is ad-free and totally free, like almost all Google office applications.

Gaaiho PDF Reader
Although Gaaiho's PDF reader is not as popular as Adobe, Foxit or Xodo's, the truth is that we are dealing with a developer with more than 20 years of experience developing tools for PDF. Its main virtue is its ability to load, manage and view documents in an agile, clear and really fast way.
We can also add comments or edit bookmarks at high speed, marking the page that interests us to return later. Also included are basic annotation tools such as text underlining or freehand drawing, arrows, geometric figures, etc.
Gaaiho also allows access to documents stored in the cloud, although for now it only works with Dropbox. However, it does offer support for the configuration of WebDAV servers (a function that is not widely used, but that more than one may be interested in).
