Adobe Acrobat Reader (download for Android) may be the go-to app for viewing, annotating, collaborating on, filling out, signing and storing PDF documents on your phone or tablet.

But you'll have to pay $24.99 per month for an Adobe Acrobat Pro DC subscription to take advantage of many of the app's most coveted features, such as organizing and editing PDFs, creating PDFs from documents and images, exporting PDFs to other file formats, combining multiple files into a single PDF and sending documents to reviewers. Or maybe you don't even need the comprehensive toolset that Adobe's premium subscription offers.

Whether you're looking for a more affordable PDF editor or only need one that's more barebones to complete a simple task like signing a contract, we've got you covered with our picks for the best alternatives to Adobe Acrobat Reader.
