Document Track Changes: The 2026 Guide for Web Editors
TL;DR
Document track changes is a feature that records every insertion, deletion, and formatting edit made to a document, attributing each change to a specific user. It lets reviewers accept or reject individual edits before a document is finalized. The feature is standard in desktop tools like Microsoft Word, available as “Suggesting mode” in Google Docs, and increasingly critical in web-based editors where dedicated plugins are often required to achieve it.
Collaborative writing without accountability is chaos. Two people edit the same paragraph, and nobody knows who changed what or why. Document track changes solves this by creating a granular, visible record of every edit, tied to the person who made it.
The concept originated in desktop word processors, but the demand has shifted. Product teams building web applications now expect the same track changes capabilities inside browser-based editors. That shift has created both confusion and opportunity.

Definition
Track changes is a document editing feature that records every insertion, deletion, and formatting modification made by each user, allowing reviewers to accept or reject individual edits before finalizing the document.
Microsoft defines it simply: “Track Changes is a feature in Microsoft Word that records and displays all changes made to a document.” The feature creates an auditable record of how a document evolved from draft to final version, making it possible to see not just the current state of the text but the full path it took to get there.
In practice, track changes serves three purposes simultaneously: it provides accountability (who changed this?), transparency (what exactly changed?), and control (should this change stay or go?).
For a deeper technical explanation, the developer guide to track changes covers the concept from an implementation perspective.
How Document Track Changes Works
The core mechanics are consistent across every implementation, whether you’re working in Microsoft Word, Google Docs, or a custom web application.
Insertions and Deletions
When a user adds text, the new content is visually marked, typically with underlining or highlighting. When text is removed, it appears with a strikethrough rather than disappearing entirely. This way, both the old and new versions of the content are visible at once.
User Attribution
Each person editing the document is assigned a distinct color or identifier. If three reviewers edit the same paragraph, you can immediately see which edits belong to whom. This attribution is what separates track changes from simply having an “undo” button.
The Accept/Reject Workflow
The real power of document track changes lies in the review step. A document owner or lead editor can go through each tracked edit and either accept it (making it permanent) or reject it (reverting to the original text). This creates a controlled, deliberate process for incorporating feedback rather than a free-for-all.
Display Modes
Most implementations offer different views. Microsoft Word, for example, provides “All Markup” (showing every change inline), “Simple Markup” (indicating where changes exist without cluttering the text), and “No Markup” (showing what the document would look like if all changes were accepted). Some editors display changes inline while others use margin balloons for deletions and comments.
Track Changes vs. Version History
This is the single most common confusion, and it matters a lot.
Version history records snapshots of a document at different points in time. It tells you that the document changed, when it changed, and who saved that version. As one SharePoint expert explained, version history “records a new edition of your file” but “does not track changes within a file.”
Track changes records the specific edits inside the document. It tells you that someone deleted a sentence in paragraph three, added a clause to paragraph seven, and reformatted the heading.
| Track Changes | Version History | |
|---|---|---|
| What it records | Individual insertions, deletions, formatting edits | File-level snapshots at save points |
| Granularity | Character-by-character | Whole document |
| Attribution | Per edit, per user | Per version, per user |
| Review workflow | Accept/reject each edit | Restore or compare versions |
| Primary use | Collaborative editing and review | Recovery and rollback |
Both features are valuable, and they complement each other. But they solve different problems. For a more detailed comparison, see this guide on revision history vs. track changes.
Where Document Track Changes Is Used
Desktop Applications
Microsoft Word has offered track changes for decades, making it the reference implementation most people think of. LibreOffice Writer and Apple Pages include similar features. In Word, “additions, deletions, moves, and formatting changes appear in a different color in the text,” making multi-author collaboration straightforward.
Cloud Documents
Google Docs doesn’t call its feature “track changes.” Instead, it uses “Suggesting mode,” which functions nearly identically. Users switch from Editing mode to Suggesting mode, and from that point, every edit appears as a suggestion that document owners can accept or reject. Former Word users often search specifically for this equivalent.
Web-Based Rich Text Editors
This is where things get complicated. Popular web editors like TinyMCE, CKEditor, and Froala are embedded in thousands of web applications, from content management systems to legal tech platforms to SaaS products. These editors provide rich text editing, but track changes support varies widely.
CKEditor 5 offers track changes as a premium feature. Froala introduced it in version 4.0. TinyMCE’s real-time collaboration plugin was retired on December 31, 2023, leaving users who need track changes to find third-party solutions.
For TinyMCE users specifically, track changes plugins fill the gap left by that retirement.
Custom Web Applications
CMS platforms, SaaS products, legal tech tools, and publishing systems frequently need document track changes built directly into their editing interfaces. Developers on Drupal forums have been actively asking how to create track changes modules for CKEditor integration, confirming that this demand extends well beyond off-the-shelf editor users.
Common Use Cases
Legal Document Review and Redlining
“Redlining” is essentially track changes applied to contracts and legal documents. For documents where accuracy is critical, such as legal files or business reports, track changes helps teams collaborate without losing original content. Law firms and corporate legal teams rely on it daily.
Regulatory Compliance and Audit Trails
Regulations like GDPR, HIPAA, and SOX rely on traceable document histories to verify compliance. A survey by Centraleyes found that 75% of businesses reported costly fines due to non-compliance. Document track changes provides the edit-level audit trail that regulators expect.
Publishing and Editorial Workflows
Editors, authors, and fact-checkers need to see exactly what changed between drafts. Track changes makes it possible for an editor to suggest rewording, for an author to push back, and for a final reviewer to approve everything, all within the same document.
Multi-Stakeholder Content Approval
When marketing copy needs sign-off from legal, brand, and product teams, track changes keeps the process organized. Each reviewer’s edits are marked in a different color, and reviewers can set up usernames or initials to clarify who contributed which edits. For teams managing this across web applications, understanding who benefits from track changes in embedded editors can help scope the right solution.
Academic and Technical Writing
Research papers, technical documentation, and grant proposals all involve multiple contributors and rounds of revision. Track changes prevents the “which version is latest?” problem that plagues email-based review cycles.
Track Changes in Web-Based Editors
Building track changes on top of the browser’s contentEditable API is genuinely hard. The New York Times recognized this early and created ICE, an open-source track changes library for web content. But ICE’s browser support was limited to Firefox 5+ and WebKit browsers with minimal IE support, and the project has gone largely unmaintained.
The core challenge is what you might call the track changes trilemma for web editors: performance, fidelity, and multi-user support all compete with each other. Tracking every keystroke from multiple users while maintaining clean HTML output and acceptable speed requires serious engineering. Since contentEditable elements don’t fire a native change event, detecting changes requires listening to the input event and diffing the DOM, a non-trivial problem.
One commenter on the Froala blog captured the developer mindset well: tracking is useful “as long as it can be taken out and does not add a lot of overhead.” Performance and clean output are real concerns.
This difficulty is why dedicated plugins exist. Rather than building track changes from scratch (which could take months of engineering time), teams can integrate purpose-built plugins that handle the complexity.
Here’s how the major editors stack up:
| Editor | Track Changes Support |
|---|---|
| CKEditor 5 | Premium feature, built-in |
| CKEditor 4 | Available via third-party plugins |
| TinyMCE | Native plugin retired Dec 2023; third-party plugins required |
| Froala | Introduced in v4.0; plugin options also available |

Best Practices for Using Track Changes
Enable tracking before sharing. This sounds obvious, but it’s a common mistake. If tracking isn’t turned on when edits begin, those edits won’t be recorded. Make it the first step in any review workflow.
Use consistent author attribution. Every user editing the document should have a clear username or identifier. Anonymous tracked changes defeat the purpose of accountability.
Accept or reject all changes before publishing. This is not optional. Multiple governments have been embarrassed by publishing documents with residual tracked changes visible. The UN, UK government, and US state attorneys general have all released documents where early drafts and discarded thoughts were exposed through unresolved track changes.
Combine track changes with inline comments. Track changes shows what was edited, but not always why. Pairing edits with inline comments gives reviewers the context they need to make informed accept/reject decisions.
Strip metadata from final documents. Before distribution, use your editor’s “Accept All” function and inspect the document for hidden metadata. This protects confidentiality and prevents the kind of accidental disclosure mentioned above.

Frequently Asked Questions
What is document track changes?
Document track changes is a feature that records every edit made to a document, including insertions, deletions, and formatting changes. Each edit is attributed to a specific user and can be individually accepted or rejected during a review process.
How is track changes different from version history?
Version history saves snapshots of an entire document at different points in time. Track changes records the specific, character-level edits within the document. Version history tells you a document changed; track changes tells you exactly what changed and who changed it.
Does Google Docs have track changes?
Yes, but Google calls it “Suggesting mode.” When you switch from Editing to Suggesting, every edit you make appears as a suggestion that the document owner can accept or reject. The functionality is very similar to Microsoft Word’s track changes.
Can I use track changes in web-based editors like TinyMCE or CKEditor?
Yes, but support varies. CKEditor 5 includes it as a premium feature. TinyMCE retired its native collaboration plugin in December 2023, so third-party plugins are now required. Froala added track changes support in version 4.0 and also supports plugin-based solutions.
Why is track changes important for compliance?
Regulations like GDPR, HIPAA, and SOX require organizations to maintain traceable records of document edits. Track changes provides an edit-level audit trail showing who changed what and when, which is exactly what auditors and regulators look for.
What happens if I publish a document with unresolved tracked changes?
Unresolved tracked changes can expose earlier drafts, deleted content, and internal discussions to anyone who opens the document. Multiple government agencies have accidentally published sensitive information this way. Always accept or reject all changes and strip metadata before distributing a final document.
Is it hard to implement track changes in a web application?
Yes. Building track changes on top of the browser’s contentEditable API involves significant complexity around change detection, multi-user attribution, and clean HTML output. This is why most teams use dedicated plugins rather than building from scratch.
Can track changes and inline comments work together?
They should. Track changes shows what was edited, while inline comments explain why. Using both together gives reviewers full context and leads to better editorial decisions. Most modern editors and plugins support both features in parallel.
