PDF Pro: Edit, Sign & Fill PDF

Review by eFreeware

PDF Pro is built around a simple idea: one Android app that covers most of what people need to do with a PDF rather than sending them between a reader, a scanner and an office suite. PDF Pro: Edit, Sign & Fill PDF is an all-in-one reader and annotator, covering reading, markup, form filling, e-signatures, page management and conversion to Word, Excel or PowerPoint. That breadth is the most distinctive thing about it.

It is a free download with ads and in-app purchases, and it has clearly found an audience: more than 10 million installs and a 4.1 average from 110,876 ratings. If you regularly deal with forms, contracts, scanned paperwork or documents that arrive as PDFs and need small changes, this is the kind of app worth considering. If your PDF needs are occasional and narrow, a lighter tool may be enough.

Reading and marking up documents

The core of the app is a reader. You can open a PDF, add notes and comments, highlight, underline or strike through text, search for a phrase, and bookmark pages you want to come back to. For study material, reports or long contracts, those are the tools that matter most, and having search and bookmarks alongside markup means you can move around a document without losing your place.

Annotation is where a phone app lives or dies, because the screen is small and precision matters. What the developer describes is a standard set of markup tools rather than anything exotic, which is probably the right call for a utility like this. The value is in having them in the same place as the reading view, so you can mark something up the moment you notice it.

The app also handles the paperwork side of reading. You can fill out a PDF form, save it and send it on, and add an e-signature to a shared document. For anyone who receives forms by email and has to return them signed, that combination removes a step that would otherwise mean printing, signing and scanning.

Scanning, converting and organizing files

Beyond reading, PDF Pro takes in new material. You can scan documents with the phone and the developer promises clear, sharp scan quality, which is the sort of claim that depends heavily on your camera and lighting. You can also turn an existing image into a new PDF, which is useful when a photo of a receipt or a whiteboard needs to become a shareable document.

Conversion runs the other way too. The app exports PDFs to Word, Excel or PowerPoint, so a document that arrives locked into PDF form can be brought into an office workflow. It also handles page-level editing: merging and splitting files, deleting pages, changing their order and inserting blank pages. Those are the unglamorous tasks that come up whenever a document has to be assembled rather than simply read.

File management is part of the package as well. Documents can be starred, renamed, copied, moved or deleted, and the app reaches into Dropbox and Google Drive so you are not limited to files already stored on the phone. For anyone who keeps work documents in cloud storage, that connection is likely to be the difference between using the app regularly and forgetting about it.

What the subscription adds

PDF Pro is free to download and supported by ads, and it also offers in-app purchases. The developer presents a subscription as the way to get more PDF power, with a three-day free trial, and lists editing text and images inside a document, combining files and organizing pages, creating PDFs from documents or images, exporting to Word, Excel or PowerPoint, and filling, signing and sending forms among the things it covers.

That is worth reading carefully before you commit. The trial gives you a way to see whether the paid tools fit how you work. My advice is to start with the free version on a real document you already have, then decide whether the subscription fits into your routine.

Getting set up

There is not much to prepare. You install the app, open a PDF or scan a document, and begin. If your files live in Dropbox or Google Drive you can connect those accounts and pull documents in from there, which saves moving files around by hand.

One practical point is the subscription. The app was released in November 2019, and the most recent update, in January 2026, mentions bug fixes and performance improvements alongside WPS Office version 7.4.3.

Who gets the most from it

This app fits people whose PDF work is varied and frequent. If you handle contracts, forms, invoices, scanned paperwork or study material on a phone, and you want reading, markup, signing, scanning and conversion in one place, the range of tools here is the appeal. Small business owners, administrators, students and anyone who deals with documents away from a desk are the natural audience.

It also suits people who already keep files in Dropbox or Google Drive, since the app works with both. The trade-off is that the free version carries ads. If you only ever need to read a PDF or add a quick signature, the free tier may be all you touch.

The 4.1 average from a large number of ratings suggests a broadly satisfied user base rather than a niche favorite, which is what you would expect from a general-purpose document tool. It is not a specialist app for one narrow task, and it does not pretend to be.

A capable document toolkit for Android

PDF Pro covers a lot of ground for a free download: reading, annotation, search, bookmarks, form filling, e-signatures, scanning, conversion to Office formats and page-level file management, with cloud access to Dropbox and Google Drive. The three-day trial lets you judge whether you need the subscription.

I would suggest it to anyone who deals with PDFs regularly on a phone and wants one app instead of three. Install the free version, try it on the documents you actually handle, and let that decide whether the paid tier is worth it. If your needs are light, the free tools will likely carry you.
