6 Best Office and Document Apps for Android in 2026

Phone office work is not one activity. It is four, and each maps to a different kind of app.

Type. Write a document in the format the person on the other end expects. Word, Google Docs, WPS.

Present. Build and deliver slides. PowerPoint, and it is not the one you would guess.

Read and sign a PDF. Because that is what your inbox actually sends you. Adobe Acrobat.

Turn paper into a file. Because you signed a paper form, not a PDF. CamScanner.

The trick is to match the app to the format, not to match it to a brand. The worst mistake is installing the app with the biggest logo when the format that arrived is one it will mangle.

Every version, size, minimum Android and licence below is the catalogue entry for the package this site serves.

The typers

1. Microsoft Word — the one that keeps the format

Word is the app to pick when the document already exists in Word format and has to stay that way.

• Version: v16.0.17830 · Size: 88.4 MB · Android: 9.0+ · Licence: freeware · Developer: Microsoft Corporation

Tracked changes, comments, footnotes, tables, a specific layout, a reference manager — if a .docx carries any of that, Word is the one that keeps it intact. It is also genuinely capable on mobile, with rewriting and dictation. At 4.8★ across 54,100 reviews it is the most-reviewed office app on this page, which is a fair signal of how central the format is.

The trade is that it is a heavy install and it is tied to Microsoft 365: the free tier is a viewer with basic editing, and the fuller features sit behind a subscription. If the job is simply to write on your phone, Google Docs is lighter and free.

Pick this one if: you receive or produce Word documents with real formatting, and you work in a Microsoft world.

2. PowerPoint — the one that actually works on a phone

PowerPoint is the surprise of this list: it is the only app here that is good at presenting from a phone.

• Version: v16.0.17830 · Size: 84.9 MB · Android: 9.0+ · Licence: freeware · Developer: Microsoft Corporation

Because it is built around a slide model, it works on a phone in a way the others do not: you can present from the device, use the presenter view and switch slides while your audience sees the clean cut. It also keeps animations, transitions and embedded media intact when the file is a .pptx. At 4.8★ across 38,200 reviews it is solid.

The trade is the same subscription shape as Word, and 84.9 MB is a heavy install for something you may use rarely. But when you are asked to present from a phone, this is the app that makes the file look like it is supposed to.

Pick this one if: you have to give a deck, and the format is PowerPoint.

3. Google Docs — the free, collaborative, always-synced one

Docs is the writer for the person who is not attached to a specific format.

• Version: v1.26.322.0 · Size: 42.2 MB · Android: 8.0+ · Licence: freeware · Developer: Google LLC

Real-time editing, live sync into the Google account you use everywhere, free with no subscription, and the lightest install of the three writers at 42.2 MB. If the work is being done by several people, this is the choice — you see the edits as they happen. At 4.8★ across 38,400 reviews it is well regarded.

The trade is format fidelity. If you export to .docx, complex layout and tracked changes get flattened. If a Word document is going to be sent somewhere and must keep its shape, use Word. If the work lives in the cloud and is collaborative, use Docs.

Pick this one if: the work is shared, lightweight and mostly text, and you want it free.

4. WPS Office — the one app that is a whole suite

WPS Office is the answer to the person who wants Word, Excel and PowerPoint from one free install.

• Version: v18.12.0 · Size: 142.6 MB · Android: 7.0+ · Licence: freeware · Developer: Kingsoft Office Software

A word processor, a spreadsheet and a presentation tool in one app, with a very recognisable Microsoft look and a large feature set. It will open most Office files. At 4.8★ across 9,630 reviews it is well liked by the people who use it, and it is the only suite here that gives you all three in one place.

The trade is at the other end of the scale: 142.6 MB is by far the heaviest install on this page, and the free version is ad-supported. It is also not a strip-down of Microsoft Office, so some complex features do not translate exactly.

Pick this one if: you want one free app that opens everything, and you can live with the size.

The PDF readers

5. Adobe Acrobat — the one for a PDF that arrived and needs signing

Acrobat is the app for the PDF that your inbox sends you, because it is the format's inventor and the one that works with it most completely.

• Version: v24.11.0 · Size: 52.7 MB · Android: 8.0+ · Licence: freeware · Developer: Adobe Inc.

Fill in a form, sign it with a saved signature, annotate and highlight, and share — all the things you actually do with a PDF that arrives on your phone. The free tier genuinely covers the standard use of reading, filling and signing. At 4.8★ across 9,140 reviews it is well regarded for a very specific job.

The trade is that the deeper features — more editing, more cloud, more conversions — sit behind a subscription, and the app started pushing an account sign-in more aggressively than it used to. For the basic job it is the right tool.

Pick this one if: a PDF is the thing you receive, read, fill or sign.

The scanner

6. CamScanner — the one that turns paper into a file

CamScanner is the other direction from every app above: it produces documents rather than opening them.

• Version: v6.68.0 · Size: 89.4 MB · Android: 7.0+ · Licence: freeware · Developer: CamScanner (INTSIG Co.)

Photograph a paper, and it crops, straightens and enhances it into a clean PDF — receipts, contracts, handwritten notes, pages of a book. OCR makes the text searchable in many cases. At 4.9★ across 8,420 reviews it is the highest-rated app on this page, which is a fair signal of how well it does one thing.

The trade is that it is a 89.4 MB install for a scanner, and the best OCR and export features sit behind a subscription. It also reads a page you photograph, so it needs decent lighting and a steady hand to give you a usable result.

Pick this one if: you have paper that needs to become a file, and it has to look like a scan rather than a photo.

The six, side by side

What none of these fix

None of them replaces a desktop for formatting. A phone app can edit and present, but a large, heavily-formatted document is still a desktop job. These are for the quick version of the work, not the whole of it.

Format compatibility is a one-way street. It is much easier for Word to open a Google Doc than the other way around. If you are the person receiving the file, match the app to the sender's format.

Free usually means free-tier. WPS, Adobe, CamScanner and Microsoft all gate the deeper features behind a subscription. Only Google Docs is genuinely free at the thing it does.

A scanner is not a photocopier. CamScanner makes a clean digital copy of a page, but it cannot straighten a crumpled receipt or rescue a page photographed in bad light.

The two-minute version

Writing and it has to stay Word? Word.

Free and collaborative? Google Docs — lightest writer here.

Presenting from the phone? PowerPoint.

A PDF to fill or sign? Adobe Acrobat.

Paper to a file? CamScanner.

Every app named here resolves to a page in the FileCobra catalogue — the build fails if one does not. Versions, package sizes and system requirements are read from that catalogue rather than written by hand. Where our ingestion worker has fetched a release itself, it records a SHA-256 of the exact file we serve and publishes it on the app’s page. We do not run an antivirus lab: where a VirusTotal report exists we link it, and where none exists we say so rather than imply one.
