Best All Documents & PDF Reader alternatives in 2026
All Documents & PDF Reader promises one thing that sounds handy on paper: open PDF, Word, Excel, PowerPoint, TXT, and even HWP files from a single app. The reader works, and the PDF editor covers the basics. The trade-offs show up quickly. The ad load is heavy, the “home screen enhancement” toggle rewrites your launcher layout in ways users find hard to undo, and the developer is not a name most people recognise from the Office or PDF category. Combine that with a 3.2-star average rating on Google Play, and it is fair to look at alternatives before it becomes the default handler for every document on your phone. These seven All Documents & PDF Reader alternatives cover the free, paid, and open-source options that actually own their categories.
We picked seven Android apps that open the same file formats, published by companies with a real track record in office or PDF software.

Why people leave All Documents & PDF Reader
Ad density is high. Full-screen ads land between opening a document, closing it, and returning to the file list. Reddit and Play Store reviews call out the frequency as the primary reason for uninstall.
Home screen changes. The app’s post-install “enhanced home screen” step reorganises the launcher layout. The description says it is reversible, but users who did not opt into anything of the sort still find the change disorienting.
Broad permissions. File access covers documents and media across the whole device, and the app asks up front rather than at first-use. That is a bigger surface than most alternatives need.
Unknown publisher. The developer is not a name from the Office or PDF category. When something opens sensitive files (contracts, medical PDFs, financial statements), a recognisable publisher matters.
Poor rating average. A 3.2-star average tells its own story. Reviews cite ads, unwanted changes to the phone, and occasional rendering issues on complex Office files.
The best All Documents & PDF Reader alternatives
1. WPS Office, best all-in-one office suite
WPS Office is the most complete free office suite on Android. It opens and edits DOCX, XLSX, PPTX, PDF, TXT, and more, with a UI that mirrors Microsoft Office closely enough that anyone from a Word background gets going in minutes. Kingsoft, the publisher, has been in the office-software category for over three decades. WPS Office vs All Documents & PDF Reader: WPS actually edits Office files, not just reads them, and the PDF module covers annotation, merge, and split.
Where it falls short: the free version shows ads and pushes toward WPS Premium. Cloud features are tied to WPS’s own account system unless you pipe files through a third-party cloud manually.
Pricing: free with ads. WPS Premium is a monthly or annual subscription that removes ads and unlocks the deeper PDF tools.
Switching from All Documents & PDF Reader: install WPS, open the same folder you were browsing in All Documents, and set WPS as the default handler for DOCX, XLSX, PPTX, and PDF in the Android app defaults.
Bottom line: the right pick when the phone needs one app that opens and edits every mainstream document format.
2. Adobe Acrobat Reader, the reference for PDFs
Adobe Acrobat Reader is the PDF reader everyone else compares to, published by the company that invented the format. The free Android reader renders PDFs faithfully, handles fillable forms and digital signatures, and syncs bookmarks and annotations across devices when you log in with a free Adobe account. Over 500 million downloads. Adobe Acrobat vs All Documents & PDF Reader: for PDFs specifically, Acrobat is the safer default. Rendering fidelity on complex documents (annotated legal PDFs, forms, tagged accessibility PDFs) is the reference point.
Where it falls short: it does not open Word, Excel, or PowerPoint files. Editing PDFs (text edits, image swaps, page management) sits behind Acrobat Premium.
Pricing: free reader with sign-in and annotations. Acrobat Premium is a monthly or annual subscription for editing, converting, and combining PDFs on mobile.
Switching from All Documents & PDF Reader: install Adobe Acrobat, sign in with a free Adobe ID for sync, then set it as the default PDF handler in the Android app defaults.
Bottom line: the default answer when PDFs are the priority and Word or Excel editing is not.
3. Xodo PDF Reader, best free PDF editing
Xodo PDF Reader is the free PDF tool most Android users end up on after leaving generic readers. Annotations, highlights, form filling, signatures, and page management all work in the free tier with no ads inside the reader itself. Owned by Apryse (the PDFTron team), which puts the same rendering engine used by enterprise apps behind the free download. Xodo vs All Documents & PDF Reader: Xodo does the PDF part better and does not chase you around the app.
Where it falls short: it focuses on PDFs. Word, Excel, and PowerPoint viewing exists but is not the strongest experience. Some advanced features push toward Xodo Pro.
Pricing: free with core reader and editor. Xodo Pro is available as a one-off unlock or subscription for the deeper toolset and offline OCR.
Switching from All Documents & PDF Reader: install Xodo, open a folder or a cloud drive, and start annotating a familiar PDF. Xodo remembers files across sessions without a login.
Bottom line: the sweet spot when the daily driver is PDFs and the ad-free free tier matters.
4. Foxit PDF Editor, best serious PDF editor on mobile
Foxit PDF Editor brings a desktop-grade PDF workflow to Android: text edits, image insertion, page rearrangement, secure signatures, and form design. Foxit is the second-largest PDF software company after Adobe, and the mobile app benefits from the same engine that powers its enterprise product. Foxit vs All Documents & PDF Reader: heavier and more capable on PDFs, and comes from a publisher that specialises in the format rather than bundling it as one of many.
Where it falls short: the free version shows ads, and the deeper editing tools sit behind a paid tier. Not built for Word or Excel files.
Pricing: free with ads. Foxit paid tiers unlock the full mobile editor and remove ads.
Switching from All Documents & PDF Reader: install Foxit PDF Editor, open a PDF, and make the same edit you were trying to make in the previous app. Sign in for cloud sync if you use Foxit on the desktop.
Bottom line: the pick when serious PDF editing on the phone is a real requirement, not an occasional need.
5. ONLYOFFICE Documents, best open-source office suite
ONLYOFFICE Documents is the mobile front-end for the ONLYOFFICE suite, an open-source alternative to Microsoft Office maintained by Ascensio System. It opens and edits DOCX, XLSX, PPTX, and PDF files with strong format fidelity, and connects to your own ONLYOFFICE server or third-party clouds when you want them. Free, no ads inside the editor, released under AGPLv3. ONLYOFFICE vs All Documents & PDF Reader: real office editing, open-source code, no advertising in the reading or editing flow.
Where it falls short: the UI is functional rather than flashy. Real-time collaboration needs a connected ONLYOFFICE server or a paid cloud plan.
Pricing: free, open source. Optional paid cloud plans if you want managed collaboration.
Switching from All Documents & PDF Reader: install ONLYOFFICE Documents, point it at your local documents folder or a cloud you already use (Nextcloud, Google Drive, OneDrive), and set it as the default DOCX/XLSX/PPTX handler.
Bottom line: the right pick when open source, no ads, and real DOCX/XLSX/PPTX editing all matter.
6. Google Drive, best if the documents already live in the cloud
Google Drive on Android does more than store files. It previews PDF, DOCX, XLSX, PPTX, images, video, and dozens of niche formats without launching a separate app. Pair it with Google Docs, Sheets, and Slides for editing, and it becomes the fastest way to open and change anything already in your Drive. Free 15 GB across Google services. Google Drive vs All Documents & PDF Reader: cloud-first and format-agnostic, with real editing available through the Google office apps.
Where it falls short: editing DOCX or XLSX pulls you into Google’s own apps rather than editing in place. Files stored only on the phone (not in Drive) still need a separate reader.
Pricing: free 15 GB. Google One paid plans expand storage and add extra features.
Switching from All Documents & PDF Reader: if your documents already sit in Drive or Gmail attachments, Google Drive plus Docs/Sheets/Slides is likely the fastest replacement for the reading side. Install both.
Bottom line: the fastest replacement when you already live in Google’s ecosystem and want cloud-first storage plus editing.
7. Microsoft 365 Copilot, best for native Office users
Microsoft 365 Copilot rolls the mobile versions of Word, Excel, and PowerPoint into a single app, with PDF viewing and the Copilot AI assistant on top. For anyone who lives inside .docx, .xlsx, and .pptx at work, this is the app that opens those files with the highest fidelity, published by the format’s owner. Microsoft 365 Copilot vs All Documents & PDF Reader: real Word, Excel, and PowerPoint editing on the phone, from Microsoft.
Where it falls short: the free tier now shows ads inside the mobile app, and full editing (large files, advanced features, Copilot in Word/Excel) sits behind a Microsoft 365 subscription.
Pricing: free with ads for basic viewing and light editing. Microsoft 365 subscription unlocks the full editor and Copilot features.
Switching from All Documents & PDF Reader: install Microsoft 365 Copilot, sign in with a free Microsoft account (or a work account), and set it as the default handler for DOCX, XLSX, and PPTX.
Bottom line: the right pick if the working documents are Word, Excel, and PowerPoint files owned by a Microsoft 365 tenant.
How to choose
Pick WPS Office if the goal is one app that opens and edits every mainstream document format, without a Microsoft account and without cloud dependencies.
Pick Adobe Acrobat Reader if the daily workload is PDFs, and format fidelity matters more than editing.
Pick Xodo PDF Reader if you want a free PDF editor with no ads in the core reader and no push toward a subscription just to annotate.
Pick Foxit PDF Editor if serious PDF editing (text edits, page rearrangement, form design) has to work on the phone.
Pick ONLYOFFICE Documents if open source, no ads, and real DOCX/XLSX/PPTX editing all matter at once.
Pick Google Drive plus Docs/Sheets/Slides if your documents already live in Drive and cloud-first storage is a benefit rather than a friction.
Pick Microsoft 365 Copilot if the working files are .docx, .xlsx, and .pptx owned by a Microsoft 365 tenant.
Stay on All Documents & PDF Reader only if the specific need is opening HWP (Korean Hangul) documents alongside Office and PDF files, and none of the alternatives above serve that mix in one app. For any other combination, one of the seven above is a cleaner fit.
FAQ
What is the best free PDF reader on Android that isn’t from a random publisher?
Adobe Acrobat Reader and Xodo PDF Reader are the two safest defaults. Adobe is the format’s inventor; Xodo is owned by Apryse and uses an enterprise-grade rendering engine. Both are free, and both come from publishers that specialise in PDFs rather than bundling reading into a generic tool.
Can I open Word, Excel, and PowerPoint files without paying for Microsoft 365?
Yes. WPS Office and ONLYOFFICE Documents both open and edit DOCX, XLSX, and PPTX for free. WPS Office is closer to the Microsoft Office UI; ONLYOFFICE is open source. Google Drive plus Docs/Sheets/Slides opens the same files inside Google’s ecosystem for free.
Is there an ad-free PDF reader on Android?
Xodo PDF Reader does not show ads inside its core reader. ONLYOFFICE Documents shows no ads in the editor. Adobe Acrobat Reader shows occasional promotional cards for its Premium tier but no third-party ads inside the reader itself.
Which alternative to All Documents & PDF Reader supports the most file formats?
WPS Office covers the widest spread out of the box: DOCX, XLSX, PPTX, PDF, TXT, RTF, and archive formats. Google Drive previews an even wider range because Google’s cloud renderer handles dozens of long-tail formats server-side.
Are any of these open source?
ONLYOFFICE Documents is open source (AGPLv3). The Android front-ends of WPS Office, Adobe Acrobat, Xodo, Foxit, Google Drive, and Microsoft 365 Copilot are proprietary.
Do these apps ask for as many permissions as All Documents & PDF Reader?
Not usually. Adobe Acrobat Reader, Xodo, ONLYOFFICE, and Foxit ask primarily for file access. WPS Office and Microsoft 365 Copilot ask more (contacts, camera) if you turn on cloud features. Google Drive uses the standard Google account permissions.
