Free Alternatives to Word Track Changes (for Non-Lawyers)

Someone in legal, or your counterparty's lawyer, has sent you a Word file with Track Changes already switched on: a clause or two struck through, a comment bubble asking you to confirm a number. You are not a lawyer, you do not have a paid Microsoft 365 licence on this laptop, and you just need to add your own edit and send the file back without breaking whatever is already in it. This guide (published by Adira, which sells contract review and CLM software, so we have a commercial reason to want you comfortable with contract tools, though nothing below requires Adira) walks through five free ways to do that, and the one test that actually tells you whether a free tool is safe for this job.

What "surviving" a round trip actually means

Track Changes in Word marks up three things at once: the edit itself (strikethrough or underline), who made it, and any comments pinned to a sentence. "Accept" or "reject" then decides whether that marked edit becomes the real text or disappears. A free tool that can show you a tracked edit on screen is not automatically a tool that carries all three of those things through a save, especially once the file leaves that tool's own format and becomes a .docx again. That handoff, not the on-screen markup, is where most free tools quietly lose something, and it is the one thing this comparison tests.

Five free ways to work with a tracked-changes Word file

Tool	Track changes/suggesting	Accept/reject	DOCX round-trip fidelity	Comments survive?	Offline	Data location
LibreOffice Writer	Yes, native Track Changes (Edit > Track Changes)	Yes, per-change or all at once	Strong; 2026 release tested at roughly 97% formatting preservation on modern Office files; occasional corruption reported after many repeated Word/LibreOffice round trips	Yes, comment threads carry over	Yes, fully	Your device only
OnlyOffice (Desktop Editors)	Yes, native Review panel, same visual language as Word	Yes, per-change or all at once	Strong, close to native Word behaviour; the free Compare tool (since v7.0) helps you spot anything that slipped	Yes	Yes, fully	Your device only
Google Docs (Suggesting mode)	Yes, Suggesting mode; a Word file with tracked changes imports as suggestions automatically	Yes, per-suggestion "accept" or "reject" tick	Good for a single clean exchange; Google's own help pages confirm suggestions export back to Word as tracked changes and comments as Word comments, but repeated multi-format round trips can shift older attribution or convert a formatting-only change into a comment instead of an inline mark	Mostly, but check after every export	Only if offline mode is pre-enabled	Google Drive (cloud)
Microsoft Word for the web (free account)	Yes, real Track Changes; switch the top-left mode to "Reviewing"	Yes, native	Native, effectively perfect, since it is actually Word	Yes	No, browser-based	OneDrive (cloud, required)
Weave	No, annotation and comments only, not an accept/reject workflow	No	Not applicable, it does not save edits back into the DOCX	N/A	No, browser-based, nothing uploaded	Your browser only

Free tiers change as these products update. Use the table as a starting point and run the test in the next section on your own file before trusting any of them with a live negotiation.

LibreOffice Writer is the closest thing to a like-for-like free replacement, and it is the one most reviewers land on: it opens .docx natively (set .docx, not .odt, as your default under Tools > Options > Load/Save first) and its Track Changes menu maps almost one to one onto Word's, so a non-lawyer does not have to relearn the workflow. The honest caveat, echoed on LibreOffice's own community forums, is that bouncing the same file between Word and LibreOffice many times over raises the odds of a corrupted save, so pick one tool to finalise the execution copy in.

OnlyOffice Desktop Editors are free and unlimited on Windows, Linux and macOS, and its Review panel looks close enough to Word's that a first-time user can usually find "Track Changes" without a tutorial. Since version 7.0 its document Compare tool is free too, a useful second check after any edit. It is a separate install most people have not used before, so budget five minutes to get oriented.

Google Docs' Suggesting mode is the easiest on-ramp for a non-lawyer: nothing to install, and Google's help documentation confirms a .docx with existing tracked changes imports as Suggested Edits automatically. It holds up well for one clean send-and-return. Where it gets shakier is a contract that has already bounced between Word and Docs a few times before it reaches you, where a formatting-only change can surface as a comment instead of an inline mark, and older author attribution can flatten. If you did not create the file's edit history, run the round-trip test below before relying on it.

Word for the web, free with a Microsoft account, is the real Word engine in a browser, so fidelity is not really a question, only availability is: it needs a live connection and a file saved to OneDrive. Track Changes lives under the "Reviewing" view in the top-left mode switch rather than a separate ribbon tab, which trips up people expecting the desktop layout. Its one real gap is that Compare Documents is desktop-only.

This page would be dishonest if it implied Weave, Adira's free, no-login, in-browser tool, belongs in the table above as an equal. Weave is built for reading a contract and flagging clauses, dates and numbers as you go, not for accepting or rejecting a tracked edit inside a .docx. It earns its place before any of the tools above: a private first pass to work out what you actually want to change, before you open the real editor to produce the redline the other side needs back.

Run this test before you trust a new tool with a real negotiation

Do this once, on a throwaway copy of a real contract template, the first time you try any tool on this list.

1. Start with a .docx that already has at least one tracked change and one comment (add one in Word first if you do not have one handy).
2. Open it in the free tool you are testing. Make one small edit elsewhere in the document, then save it back as .docx.
3. Fully close the file, then reopen it in Microsoft Word itself, not the tool you just used.
4. Check three things: is the original tracked change still shown as a tracked change, not silently accepted; is the comment still pinned to the right sentence with the right author name; does the clause numbering still line up.

If any of those three fail, that tool has a fidelity problem for this workflow, whatever its marketing page claims. LibreOffice is usually the most faithful on this test among the fully free desktop options; Google Docs' Suggesting mode is the one most likely to trip on a formatting-only change turning into a stray comment. Run it once per tool before it matters, not after you have already sent the file back.

Why fidelity is a legal question, not just an annoying bug

The .docx that goes back and forth is the actual record of what each side proposed and when, not a courtesy copy. Section 63(1) of the Bharatiya Sakshya Adhiniyam, 2023, which now governs how electronic records are admitted as evidence in India, treats a computer-produced electronic record as a document in its own right:

"Notwithstanding anything contained in this Adhiniyam, any information contained in an electronic record which is printed on paper, stored, recorded or copied in optical or magnetic media or semiconductor memory which is produced by a computer or any communication device or otherwise stored, recorded or copied in any electronic form... shall be deemed to be also a document... and shall be admissible in any proceedings, without further proof or production of the original, as evidence of any contents of the original or of any fact stated therein of which direct evidence would be admissible." Source: Section 63, Bharatiya Sakshya Adhiniyam, 2023 (Indian Kanoon)

The Supreme Court has twice confirmed the certification requirements attached to this kind of record are not a formality you can skip. In Anvar P.V. v P.K. Basheer ((2014) 10 SCC 473), the Court held that a certificate is a mandatory condition for admitting an electronic record, overruling a looser earlier line of cases (judgment). It reaffirmed this in Arjun Panditrao Khotkar v Kailash Kushanrao Gorantyal ((2020) 7 SCC 1), holding the requirement is mandatory unless the original device itself is produced before the court (judgment).

You do not need a court-ready certificate for an ordinary email negotiation. Practically, it means the file itself, its tracked changes, comments, and dates, is the record a court would eventually look at if a dispute ever arose about what was offered, when, and by whom. A version a free tool silently flattened is a weaker record than one that carried through intact. Keep an unedited copy of the file from each stage, not just the version everyone finally signed.

Where your file actually goes while you work on it

Google Docs and Word for the web both need the file to sit on the vendor's cloud, Google Drive or OneDrive, to work at all, a reasonable trade for a routine contract, but worth knowing rather than assuming. LibreOffice Writer and OnlyOffice Desktop Editors process everything on your own machine, and Weave works the same way in your browser; nothing leaves your device unless you send the file yourself.

Watch out for the random "free online docx editor" site a search engine surfaces. Before trusting one, open your browser's developer tools (F12), the Network tab, and watch what fires when you open or save a test file there. A large upload to a domain you do not recognise means your document is sitting on someone else's server, on retention terms you probably have not read. If the contract carries another person's personal data, such as a salary or a home address, that also brings it within scope of India's Digital Personal Data Protection Act, 2023, one more reason to keep it off a converter you cannot vouch for.

Red flags in a free track-changes tool

Normal	Red flag	Why it matters
Opens and saves .docx directly	Forces a conversion to its own file format first	Conversion is exactly where tracked changes and formatting most often get mangled
Comment author names survive a save-and-reopen cycle	Author attribution vanishes or turns anonymous after reopening	You lose the ability to tell who proposed what once more than two people are involved
A moved clause shows as a tracked "move"	Moved text shows as an unrelated delete in one spot, insert in another	A relocated clause can look like a random edit, hiding a real change in position
The free tier's limits are stated plainly upfront	A paywall or watermark appears mid-task with no warning	You lose time, and possibly leverage, mid-negotiation
Works, or degrades gracefully, without internet	Refuses to open or save without a live connection	A dropped connection mid-edit on a confidential contract is now also a data-loss risk
"Track Changes" or "Suggesting" is a visible toggle you can see is on	The tool is silently in normal editing mode and your "edit" just overwrote the text	The other side gets a clean copy with no way to see what you actually changed

A tracked edit that survived, and one that didn't

Take a real payment clause. The vendor sends an MSA with clause 6.1 already carrying one tracked edit and a comment:

Original clause 6.1, as received: "Client shall pay all undisputed invoices within forty-five (45) days of the invoice date." (Tracked change: "forty-five (45)" replacing "thirty (30)". Comment: "Extended from 30 to 45 to match our AP cycle, please confirm this works for you.")

Bad round trip, after a fidelity-losing free tool edits an unrelated clause and saves back to .docx: Clause 6.1 reopens in Word showing only "Client shall pay all undisputed invoices within forty-five (45) days of the invoice date," with no strikethrough and no comment. The tool silently accepted the change on save. The vendor now has no way to tell, from the document itself, that 45 days was a proposal rather than the original term, or why it changed.

Better round trip, in a tool that preserved the tracked-changes and comment layer: The same clause reopens with "forty-five (45)" still shown as a tracked insertion, "thirty (30)" still struck through, both attributed to the right party with a date, and the comment still pinned to the sentence. Anyone opening the file later can see exactly what was proposed, by whom, and why.

What changed and why: the final wording is identical in both outcomes. The only difference is whether the tool carried the tracked-changes and comment metadata through the save-and-reopen cycle instead of silently flattening it. This is exactly what the round-trip test above catches.

FAQ

I don't have Microsoft Word at all. Which free tool should I use? LibreOffice Writer if you want something installed that behaves closest to Word's own Track Changes menu, or Google Docs' Suggesting mode if you would rather not install anything and the file has not already bounced between formats many times. Run the round-trip test in this guide first either way.

How do I even turn on Track Changes if I've never used it? In LibreOffice or OnlyOffice, look for "Track Changes" or "Review" in the Edit menu, same idea as Word. In Google Docs, the mode switch is top-right, labelled "Editing," "Suggesting," or "Viewing"; pick "Suggesting." In Word for the web, switch the top-left mode from "Editing" to "Reviewing." Confirm the toggle is on before you start editing, or your changes go in silently, untracked.

Will my tracked changes definitely survive if I use a free tool? Not automatically, which is the point of this guide. Run the four-step round-trip test above on a throwaway copy first. LibreOffice and OnlyOffice, both fully local, tend to hold up best across repeated round trips; Word for the web is the most faithful of all since it is literally Word, but needs an internet connection and a Microsoft account.

Can I use Weave to make tracked edits the way I would in Word? No, and this guide is upfront about that. Weave is a free, no-login, in-browser tool for reading a contract and marking up clauses as you review them, not a .docx editor with an accept-or-reject workflow. Use it to work out what you want to change, then make the actual tracked edit in Word, LibreOffice, OnlyOffice, or Google Docs.

My tracked changes disappeared after I reopened the file in Word. What happened? Most likely the tool you used flattened or auto-accepted the changes on save, a known behaviour in some free tools depending on the view mode you were in, or someone clicked "Accept All Changes" before resending. Run the round-trip test on a throwaway copy before you hand a live contract to a new tool.

Is it safe to put a confidential contract into an online DOCX editor I've never used before? Be cautious. Any tool that requires uploading your file sends it to a server you do not control, on retention terms you may not have read. Prefer a fully local option, LibreOffice or OnlyOffice Desktop, or a no-upload browser tool for the read-and-flag stage. If you must use an unfamiliar web editor, check its Network tab first, as described above.

This guide gets you to a free, working way to keep a tracked-changes Word file intact, and a test to check whether the tool you picked is trustworthy for it. It does not tell you whether a specific tracked edit, or the clause it changes, is a good deal or enforceable in your situation, that depends on the facts and the negotiation, and is not legal advice. For anything with real money or risk attached, especially payment, liability, indemnity, or termination clauses, have a lawyer look at the final, round-tripped document before anyone signs it.
