What WPS Office is, and what the vendor's pages confirm
The Analytics Insight guide says WPS Office is built by Beijing Kingsoft Office Software, Inc. It says the suite runs on Windows, Mac, Linux, iOS and Android, with Writer, Spreadsheets and Presentation as the main apps. WPS's own download page confirms the platform list: free downloads for Windows, macOS, Linux, iOS and Android. WPS's product page also describes a PDF component alongside the three core apps.
WPS's tech-specs page gives the Windows requirements. It lists Windows 11, 10, 8.1 and 7 as supported. It recommends a dual-core processor, 2 GB of memory or more, and 4 GB or more of free disk space. These are recommendations, and the vendor warns that speed depends on your CPU, RAM and disk.
The same page lists the file types each app handles:
- Writer: .wps, .doc, .docx, .dotx, .docm, .rtf, .txt and others.
- Spreadsheet: .et, .xls, .xlsx, .xlsm, .csv and others.
- Presentation: .dps, .ppt, .pptx, .ppsx and others.
- PDF: .pdf.
Being able to open an extension is not the same as handling every feature in that file correctly. WPS says the suite is compatible with Microsoft formats and works offline. Those are vendor claims.
The figures to treat with caution
The 600 million users figure. The guide notes that this number comes from WPS itself. It is not audited. WPS's own pages are also inconsistent on the point, with one place saying 600M+ monthly active users and another saying 200 million+ people.
Price list. The guide quotes Premium at US$29 a year, Professional at US$79.99 for a lifetime license, and Pro at US$2.99 a month. It attributes the first two to Capterra. WPS's current purchase page loads dynamically and did not expose a stable US price list, so these figures could not be matched to it.
Third-party listings disagree with each other. One lists Premium at $29.99 per year. Another shows WPS Pro for individuals at $2.99 per month, with $35.99 billed yearly. A third puts the cheapest paid plan at $3.99 a month, and says its data may vary. Prices appear to differ by plan name, billing term, region and date.
The guide also repeats WPS's claim that Pro costs about a third of Microsoft 365 Personal at US$99.99 a year. That comparison mixes billing periods and feature sets. Check both checkout pages on the day you buy.
Capterra ratings. The guide cites 4.5 for WPS and 4.6 for Microsoft 365, and no corroborating source for these turned up. A rating from user reviews says little about file fidelity or administration features.
"Under 60 MB" installer. The guide ties this to an older release. It says nothing about today's download, so ignore it.
King Software. The guide says a separate Dutch company called King Software sells accounting and ERP tools. I could not confirm that independently. The practical point is only that a search for "King software" may not lead to an office suite.
Ads: the guide's claim doesn't match WPS's own help page
The guide says Premium plans add an "ad-free screen". WPS's help article says something more specific. Some tools sit behind a paywall is the guide's general framing. The help page, however, says products for PC currently show no ads, whether free or paid. It says Android ads are limited to under 20%.
The same page also says paying users get ad removal, with only push notifications about WPS information and feedback activities remaining. For Windows users, the ad argument for upgrading looks weak. It may matter more on Android.
What's free and what isn't
WPS's feature comparison says core Writer, Spreadsheet, Presentation and PDF-reader features are free. It lists these as paid:
- PDF editing of text, images and links.
- PDF conversion, including PDF to Word, Excel and PowerPoint, and Office files to PDF.
- 20 GB of cloud storage on the paid plan, against 1 GB on the free tier.
- AI features with daily usage limits. WPS's comparison says that once you hit the cap, the tools pause until the next day.
The guide describes the PDF editor as paid-only, which matches. If PDF editing and conversion are your main reason to look at WPS, price the paid tier. If they are not, the free tier may be enough.
Alternatives, and what the guide can and can't support
The guide names LibreOffice as the main free rival, followed by Google Workspace and Microsoft 365. It also lists OnlyOffice, SoftMaker Office and Apple iWork. Its Microsoft 365 line is that it remains the standard for deep features and file accuracy, at a higher cost. That is a reasonable judgment, but it is the guide's opinion and not a tested result. The guide's reference to a 2016 review ranking WPS best among six free suites is a decade old and should not drive a 2026 decision.
A better way to choose is by your own requirements:
- Offline desktop editing: WPS, LibreOffice, SoftMaker, Microsoft 365 desktop apps.
- Browser-first collaboration: Google Workspace, as WPS's own comparison describes it.
- Heavy Microsoft-format dependence: Microsoft 365 is the lowest-risk option. Anything else needs testing.
- Built-in PDF tools: WPS bundles them, but editing and conversion need a paid plan.
- Apple-only users: iWork is free on those devices, according to the guide.
How to test WPS before you switch
- Download WPS Office from the vendor's official download page. Choose the Windows installer, and check your PC against the recommended specs first.
- Copy a few real files, so you never edit originals. Include one complex Word document, one Excel workbook with formulas, and one PowerPoint deck.
- Open each in WPS and compare it with the Microsoft version. Look at fonts, tables, headers and footers, tracked changes, charts and slide layouts.
- Recalculate the spreadsheet and compare results with Excel. Pay extra attention to anything involving macros or embedded objects.
- Save back to DOCX, XLSX and PPTX, then reopen the files in Microsoft Office or send them to a colleague.
- Only after that, consider a paid plan. Check the price at checkout, the renewal term, the device limits and the cancellation terms.
Privacy and business use
The guide advises businesses to read the data policy before storing sensitive files in WPS cloud storage. The guide says the company calls privacy and security central, but a marketing statement is no substitute for a data-handling review. Organizations with compliance requirements should do that review first and check where data is stored. This applies to any consumer-oriented cloud office service.
Bottom line
WPS Office is a credible free option for students, home users and small teams who mainly need basic documents, spreadsheets and slides on Windows. The vendor confirms free cross-platform downloads and broad Microsoft format support. The guide's pricing, ratings and ad-free claims are less reliable than its headline suggests. Treat it as a starting point. Verify prices at checkout, and run your own files through the free version before you commit.
