All Document Reader: PDF/Word screenshots
If your phone has become the place where contracts, spreadsheets, lecture notes and the occasional novel all end up, All Document Reader is built for exactly that pile. Eternal Mobile Labs has made a free Android app that opens PDF, Word, Excel, PowerPoint and EPUB files in one place, then layers editing, signing, scanning and file organization on top. It has drawn over a million installs and holds a 4.1 average from more than 15,000 ratings, which suggests a lot of people have found a use for it.
The pitch is breadth rather than depth in any single area. Instead of keeping a PDF reader, an office viewer and an ebook app side by side, you get one viewer that recognizes the common formats and a set of tools for the tasks that usually follow: reading, marking up, signing, scanning and tidying up. For anyone who deals with a mix of work documents and personal reading on a handset, that consolidation is the main attraction.
What I like about the framing is that it targets ordinary document chores rather than trying to be a full desktop office suite. The app covers reading, quick edits and conversions, which is a realistic scope for a phone. Whether the individual tools hold up is the question, and there is a fair amount to go on.
AI summaries for documents you would rather skim
The feature the developer leads with is a smart assistant that generates a summary of a document. The idea is straightforward: rather than working through a long report page by page, you let the app pull out the highlights and hand you a condensed version. It is pitched as a way to get through complex PDFs in seconds, and that is the claim I would treat as marketing until you have tried it on your own files.
Summaries are most useful when you already know roughly what a document covers and just need the gist, or when you are triaging a stack of reports and deciding which ones deserve a full read. For a contract, a research paper or a lengthy proposal, a quick overview before you commit to the whole thing is a reasonable workflow. I would still expect to read the source material carefully for anything that carries obligations or money.
It is worth remembering that the app is free with ads and offers in-app purchases, so the assistant sits inside a product that also has commercial elements. That does not tell you how good the summaries are, only that this is a freemium-style tool rather than a paid, ad-free utility.
Reading, annotating and signing without a desktop
Underneath the headline feature is a viewer for the formats most people actually encounter. Word files in DOC and DOCX, Excel sheets in XLS and XLSX, PowerPoint decks in PPT and PPTX, EPUB ebooks and PDFs all open in the same app. The EPUB side includes a switch between horizontal and vertical reading modes, which matters if you read novels on a phone and have a preference for how pages turn.
The editing tools are aimed at light work rather than document production. You can highlight text and attach notes while reading, which is the kind of annotation students and reviewers do constantly. There is also form filling and an electronic signature feature, so a contract that arrives as a PDF can be completed and signed on the phone instead of being printed, signed and scanned back in.
The scanner turns the camera into a document capture tool. You photograph a receipt or a page of handwritten notes and the app converts it into a PDF, and existing photos or screenshots can be converted the same way. For anyone who ends up with paper receipts or whiteboard photos that need to become files, that is a practical addition rather than a gimmick.
File management gets attention too. The app sorts documents automatically by format, grouping Word, Excel, PowerPoint and PDF files, and it includes search across your internal folder structure. Reading works offline, which the developer contrasts with other tools, so a saved document does not need a connection to open.
Merging, splitting and locking files
PDF management covers the housekeeping tasks that come up constantly. You can merge several PDFs into one document, or split a file to keep only the pages you need. Both are the sort of operation that otherwise sends you looking for a desktop machine, so having them on the phone is convenient for anyone assembling a submission or trimming a scan.
Security is handled with password protection. The app can encrypt and lock a PDF, and it can also remove a password from a protected file so it can be shared more easily. That covers the two directions most people need: keeping something private, and getting past a lock on a document you are entitled to open.
These are the features that make the app feel like a small toolkit rather than a single-purpose reader. None of them is exotic, but together they cover a lot of the small PDF jobs that otherwise interrupt your day.
What the app asks of you
All Document Reader is free to download, carries ads and offers in-app purchases. The app includes commercial elements, so I would go in expecting a free tool rather than a one-time paid product. The content rating is Everyone, and it sits in the Tools category on Google Play.
On the practical side, the app is built around working with your documents, and the scanner uses the camera. Offline reading is supported, so a document you already have on the device can be opened without a connection.
The app was released on August 28, 2025, and the most recent update, on August 24, 2026, mentions performance improvements and general fixes rather than new features. That is a normal maintenance pattern for a utility of this kind.
Getting the most out of it
The sensible way to approach a multi-tool like this is to start with the job you actually have. If you mostly read, the viewer and the EPUB mode will carry most of your use, and the annotation tools are there when a document needs marking up. If you handle paperwork, the scanner, form filling and signature features are the ones worth learning first.
The AI summary is best treated as a triage aid. Use it to decide whether a long document deserves your attention, then read the parts that matter in full. For anything with legal or financial weight, the summary is a starting point, not a substitute for the text.
File organization rewards a little discipline. Because the app sorts by format and searches your folders, keeping documents in reasonably named directories makes everything downstream easier, from finding a contract to merging the right pages. Password protection is worth using for anything sensitive before you share or store it.
Finally, remember the trade-off at the center of the app: convenience and breadth in exchange for ads and purchases. If you want a single place for documents on your phone, that is a fair deal. If you need deep editing or professional document production, a phone app of this scope is unlikely to be the right tool.
A practical pick for phone-based document work
All Document Reader is a sensible choice for people who deal with a mix of PDFs, Office files and ebooks on Android and want one app instead of several. The combination of viewing, annotating, signing, scanning and basic PDF management covers a lot of everyday document work, and offline reading plus automatic sorting by format make it easier to live with.
The caveats are clear: it is free with ads and in-app purchases, and the AI summary is a convenience rather than a replacement for careful reading. If your needs are light to moderate and phone-centered, this is a reasonable install. If you need serious editing, weigh that before you commit.
With over a million installs and a 4.1 rating, it has clearly found an audience among people who want their documents in one place. For that audience, it does the job it sets out to do.
The short verdict
A broad, free Android document viewer for PDF, Office and EPUB files, with ads and in-app purchases as the trade-off.

All Document Reader: PDF/Word: frequently asked questions
What file formats can All Document Reader open?
It handles Word documents in DOC and DOCX, Excel spreadsheets in XLS and XLSX, PowerPoint presentations in PPT and PPTX, EPUB ebooks and PDFs. All of these open in the same viewer, so you do not need separate apps for each type. The EPUB reader also lets you switch between horizontal and vertical reading modes.
Can I sign a PDF on my phone with this app?
Yes. The app includes form filling and an electronic signature feature, so a contract or form that arrives as a PDF can be completed and signed directly on your phone. You can also highlight text and add notes while reading. That covers the common case of paperwork that would otherwise need printing and scanning.
Does All Document Reader work without an internet connection?
The developer says the app supports offline document reading, so files already on your device can be opened without a connection. That is presented as an advantage over other tools. Reading is the part explicitly described as offline.
How does the AI summary feature work?
The built-in assistant extracts highlights from a document and produces a condensed summary, which the developer describes as a way to understand complex PDFs quickly. It is aimed at long reports and similar material where you want the gist before reading in full. Treat it as a starting point rather than a substitute for the original text.
Is All Document Reader free, and does it have ads?
The app is free to download and contains ads. It also offers in-app purchases. So the realistic expectation is a free tool supported by advertising and optional purchases.
