At work, we often need to send files to colleagues, clients, or managers for review, but the biggest fear is that the recipient might accidentally alter the original content or edit it directly, resulting in a completely unrecognizable document when it comes back. At this point, if the document can be set to allow comments only, without modifying the content, the problem would be solved. Let's discuss how to meet this requirement and what tools and methods are available.
Why do you need to add a password to Word to allow only commenting and no modifications?
The Word function of only allowing comments is very practical in actual work. For example, when you send a draft contract to the legal department for review, you want them to only propose modifications rather than directly altering the contract text; or when you send the initial draft of a report to a leader for review, the leader can add comments alongside without accidentally deleting important content; also, teachers grading student assignments, editors reviewing author manuscripts, etc. All these scenarios require documents that can only be commented on, not modified.

After processing:

Method 1: Use HeSoft Doc Batch Tool to restrict Word editing to comments only
Recommendation Rating: ★★★★★
Advantages:
1. Targeted design. Unlike other tools that bury this function within a pile of complex settings, the interface is very intuitive. All you need to do is check "Restrict Editing Password", then select "Allow only this type of editing: Comments", it's that simple.
2. True batch processing capability. You only need to select all these documents, set them up once, and process with one click. All documents will be protected according to the same rules.
3. Local processing ensures security. All operations are completed on your own computer, and documents do not need to be uploaded to any cloud server.
Disadvantages:
【 HeSoft Doc Batch Tool 】needs to be downloaded locally before use.
Operating Steps:
1. Download and open 【 HeSoft Doc Batch Tool 】, select 【Word Tools】 on the left, then choose 【Word Add Password Protection】 on the right.

2. Click 【Add File】 in the upper right corner, or drag the Word document to be encrypted to the designated location to complete the file upload.

3. Click 【Next】, turn on the 【Restrict Editing Password】 button, check 【Allow only this type of editing: Comments】 below, and fill in the password for lifting restrictions as needed.

4. Click 【Next】, the tool will start batch adding restriction editing passwords to Word documents, and will promptly notify you upon completion.

Method 2: Use the built-in feature of Microsoft Word to restrict editing to comments only
Recommendation Rating: ★★★☆☆
Advantages: Completely free, no need to install any third-party software. As a native Office function, it has the best compatibility; once set, the permission restrictions display correctly on any device supporting Office.
Disadvantages: Cannot batch process, each document needs to be set up individually. The operation path is deep; users unfamiliar might need to search for tutorials to find the correct setting location. Lacks a unified password management function; passwords for each document need to be recorded separately.
Operating Steps:
1. Open the Word document you need to set up, click the "File" menu.
2. Select the "Info" tab, click the "Protect Document" button.
3. Choose "Restrict Editing" from the dropdown menu.
4. In the right sidebar, check "Allow only this type of editing in the document".
5. Select "Comments" from the dropdown box, set a password, and click "Yes, Start Enforcing Protection".

Method 3: Use Word Macro Recording (Semi-Automated) to lock Word from modifications, allowing only comments
Recommendation Rating: ★★★☆☆
Advantages: Can implement repetitive operations within a single Word document, slightly improving efficiency. Recorded macros can be reused in other documents.
Disadvantages: Macro security settings may be blocked by the system. Can only process one open document at a time, limited batch processing capability. Macro compatibility might have issues across different Word versions.
Operating Steps:
1. Open Word, click "View" -> "Macros" -> "Record Macro".
2. Name the macro and assign a shortcut key, start recording.
3. Following the manual steps above, set "Restrict Editing" to Comments.
4. Stop recording, save the document.
5. Apply the macro to other documents using the shortcut key, but they need to be opened individually.

Method 4: Use Adobe Acrobat Pro (Convert to PDF) to prevent Word from being modified
Recommendation Rating: ★★★☆☆
Advantages: The generated PDF format is more secure, with excellent cross-platform compatibility. Complex permission management can be set, including printing, editing, etc.
Disadvantages: Requires conversion to PDF, losing the editing flexibility of Word. Acrobat Pro is not specifically designed for Word documents, making the operation somewhat circuitous.
Operating Steps:
1. Open the document with Word, save it as a PDF format.
2. Open the PDF file with Acrobat Pro.
3. Click "Tools" -> "Protection" -> "More Protection".
4. Select "Security Properties With Password".
5. Restrict editing in the permission settings, allowing commenting.

Method 5: Use LibreOffice (Open Source Alternative) to prevent Word from being modified
Recommendation Rating: ★★★☆☆
Advantages: Completely free and open source, rich in features. Supports batch processing macros, theoretically enabling automation.
Disadvantages: Compatibility issues with MS Word sometimes occur. The setup interface and operation logic differ from Word, requiring relearning.
Operating Steps:
1. Launch LibreOffice, select the "Open File" function, find the Word document you need to set up (supports .doc and .docx formats), and import it into the software's workspace.
2. In LibreOffice's top menu bar, click "File", find and click the "Properties" option from the dropdown menu, select the "Security" tab in the pop-up dialog box, and enter the permission settings interface.
3. In the security settings interface, first check the "Open file read-only" option and enter a password, then find the document protection related options, setting the editing restriction to "Suggest read-only" or fully restrict editing.
4. In the dropdown menu of protection options, the system defaults to the "Read-only (recommended)" option. You can choose "Custom" to set more granular permissions, such as allowing commenting, allowing form filling, and other specific operations.
5. After completing all settings, click "OK" to save the settings, then click "File" -> "Save As" again, making sure to select the save format as "Microsoft Word Document (.docx)" to ensure compatibility with Word.

Method 6: Use OnlyOffice (Enterprise-level Online Document) to prevent Word from being edited but allow annotations
Recommendation Rating: ★★☆☆☆
Advantages: Open source and free, supports private deployment. Powerful collaborative editing features, fine-grained permission control.
Disadvantages: Requires setting up your own server or using its cloud services. Relatively complex configuration for individual users.
Operating Steps:
1. First, you need to install and deploy the OnlyOffice service on your own server, or directly access the official online OnlyOffice platform, register and log into your account.
2. After successfully logging in, enter the document management interface, click the upload button to upload the Word documents you need to set up to the system, supporting batch upload of multiple files.
3. After the upload is complete, find the target file in the document list, right-click and select "Properties" or "Settings" to enter the detailed access permission configuration page.
4. Find the editing permission option in the permission configuration area, select the "View and comment" level from the dropdown menu, so users can only add annotations without modifying the original text.
5. After the permission settings are complete, click the generate share link button, copy the link, and send it via email or instant messaging tool to the relevant users who need to review the document.

Good tools should make work easier, not more complicated. Whether it's contract review, report review, assignment grading, or manuscript evaluation, setting appropriate document protection permissions can ensure document security while facilitating collaborative communication. Choose the tool that suits you and make document management more efficient and orderly.
