Word for the Web vs Desktop — Feature Gaps Microsoft Documents (and a Third Path)

Microsoft publishes the differences between Word for the web and desktop Word. Most comparison blogs paraphrase marketing pages. This article sticks close to those documented gaps, then adds the question Microsoft’s matrix does not answer: what if you need to edit a .docx without a Microsoft account and without creating a OneDrive copy?

Primary sources:

• Word features comparison: web vs desktop
• Differences between using a document in the browser and in Word

Gap map (the ones that change decisions)

Password protection and IRM

Microsoft’s comparison notes password protection and restricted editing behave differently on the web — often read-only in the browser, with real editing pushed to the desktop app. Information Rights Management (IRM) protected files similarly belong on desktop Word.

EditDocx: password-protected / encrypted files are unsupported. Same stop condition, different product — do not treat any casual web editor as a way around encryption.

Autosave and version history

Word for the web autosaves to OneDrive/SharePoint. Version history is a server feature (OneDrive/SharePoint UI), not a local File → Save As culture.

EditDocx: there is no cloud autosave of document content to EditDocx. Ctrl/Cmd+S checkpoints IndexedDB on the device. Download is the durable artifact. That is either a feature (privacy) or a footgun (forgot to download) depending on hygiene.

Formats

Word for the web expects modern cloud documents; legacy binary .doc / .dot are converted or refused depending on path. EditDocx targets .docx (Word Open XML) and .xlsx for spreadsheets.

Co-authoring

Word for the web + desktop Word (current) support co-authoring on OneDrive/SharePoint files.

EditDocx: solo only. If you need simultaneous cursors, stay in Microsoft’s stack (Word Online alternative explains when we are not the fit).

Decision tree

Need live co-authoring in a tenant?
  YES → Word for the web / desktop Word on SharePoint
  NO  → Is the file password/IRM protected or macro-heavy?
          YES → Desktop Word
          NO  → Must you avoid Microsoft account + OneDrive copy?
                  YES → EditDocx (verify after download)
                  NO  → Word for the web is fine if you already live in 365

Worked examples

A. Contractor on a client laptop

Attachment NDA, no personal Microsoft login allowed on the machine.
→ EditDocx private window → edit → download → clear site data.
See locked-down PC and threat model.

B. Team handbook in SharePoint

Five editors, comments flying.
→ Word for the web. EditDocx would be the wrong tool.

C. Macro-enabled invoice template from IT

→ Desktop Word only. Neither Word for the web nor EditDocx is the automation host you want.

D. Student paper on a library PC

No install rights, homework due.
→ EditDocx or Word for the web with a school account. If the school account is unavailable, EditDocx; verify fonts/tables (fidelity).

Where cloud-default desktop Word enters the story

Separately from Word for the web, Microsoft has been pushing cloud-first save defaults for new desktop documents in Microsoft 365 Insiders (2025 announcement; broader rollout expected). That does not erase local save options, but it changes defaults. For a privacy-oriented walkthrough of that pressure, see our companion piece Word’s push toward OneDrive by default and third-party analysis such as Proton’s.

FAQ

Does Microsoft say EditDocx is better than Word?

No. Microsoft documents Microsoft products. We cite their matrix to make honest comparisons.

Can Word for the web edit without OneDrive?

In normal consumer/tenant setups, Word for the web is cloud-backed. That is the product.

Is EditDocx offline forever?

No. The shell needs network at least to load. Document processing stays in the tab (mostly offline notes).
