Many PDFs sent to clients, students, or colleagues need to be easy to view and print, while preventing direct content modification. This article introduces a batch processing method: using the PDF password protection feature of HeSoft Doc Batch Tool , you can uniformly set a read-only password for multiple PDFs without setting an open password, and enable printing and text copying. After processing, the PDFs can still be read normally, but a permission password will be required for editing, making it suitable for use before batch distribution of official materials.
PDF is a very common delivery format in office work. Whether it's enterprise contracts, training materials, learning documents, product introductions, or customer service instructions, many people choose to export Word, doc, docx, PPT, or other documents as PDF before sending. However, in actual work, PDFs are not always “naturally read-only.” If the recipient uses professional PDF editing software, they may still enter editing mode and modify the text, titles, links, or layout elements in the page.
For a batch of PDFs that need to be distributed externally, the most ideal state is often not “completely unopenable,” but rather “viewable normally, printable, and text-copyable, but not freely editable.” This way, it does not affect reading and usage, while protecting the stability of the file content. This article will combine screenshots to explain how to use the office software HeSoft Doc Batch Tool to batch-add read-only protection to multiple PDFs.
Applicable Scenarios: Convenient Reading While Restricting PDF Modification
Many teams encounter permission control issues before publishing materials. For example, a training institution needs to distribute learning materials; students should be able to read, print, and extract text, but should not arbitrarily change the original materials. A sales team needs to send product manuals or quotation descriptions; customers can view and print, but the file content should remain consistent. When legal or administrative departments send contract samples, system documents, or notification PDFs, they also hope to avoid versions being privately modified.
If you only add an open password to a PDF, it introduces a new problem: each recipient must enter a password when opening it, which reduces dissemination and review efficiency. Especially for public materials, internal knowledge bases, courseware packages, and other files that inherently need to be viewed by multiple people, setting an opening threshold is unsuitable. Therefore, a more appropriate approach is to set a "file content read-only password," which means restricting editing permissions rather than reading.
When the number of files is small, manual processing is still acceptable; but if there are a dozen or dozens of PDFs in a folder, setting passwords, saving, and checking them one by one can be very tedious. The value of HeSoft Doc Batch Tool lies in turning these repetitive operations into a one-time batch task.
Effect Preview: From Editable PDF to Protected PDF
Before Processing: Multiple PDFs in a Folder Need Unified Protection
Before processing, multiple PDF files are placed together in the same location. From the screenshot, you can see files like human-exploration.pdf, Learn_English_in_an_easy_fast_and_fun_way.pdf, learning-tips.pdf, SampleContract-Shuttle.pdf, services.pdf in the folder. If this type of batch PDFs all need the same permissions set, using a batch processing tool is very suitable.
Opening one of the PDFs for viewing, you can see it is in the “Edit PDF” state in Adobe Acrobat Pro DC. The page text objects are already selected, and the right side displays format settings like font, font size, and alignment. This indicates that the content of this PDF can currently be edited, and the text content and page elements have the possibility of being altered.
After Processing: Attempting to Edit Prompts for a Permission Password
After batch protection is applied, opening the same file again with a PDF editing tool, the page content can still be displayed, but a password prompt appears during editing operations. The window prompts that the file is protected and requires a permission password. If you don't have the password, you need to contact the document author. At the same time, you can also see "Restrict Editing" is checked in the interface, indicating that content editing is now under permission control.
This is the effect this article aims to achieve: PDFs are not unopenable, but are viewable, printable, and text-copyable, while editing actions are restricted. For materials distribution, file archiving, and external transmission, this permission setting better meets actual office needs.
Operation Steps: Batch Setting PDFs to Viewable but Not Editable
Step 1: Find "PDF Add Password Protection" in the PDF Tools
After launching HeSoft Doc Batch Tool , select "PDF Tools" in the left category. This software is positioned as a document batch processing office tool, and its interface provides various PDF batch functions. According to the screenshot, "PDF Add Password Protection" is located as the 3rd item in the PDF tools list, and the description mentions it can batch-add protection measures like file open passwords and read-only passwords to PDFs.
Do not select "PDF Remove Password Protection" here, nor watermark, conversion, or merge functions. What we want to do in this article is add permission protection to PDFs, so you should click "PDF Add Password Protection" to enter the operation process.
Step 2: Import the PDF Records That Need Batch Processing
After entering the function page, the page title displays "PDF Add Password Protection." There are process steps at the top, currently at step 1, "Select records to be processed." The top right corner provides operation entries like "Add Files," "Import Files from Folder," "Clear," and "More."
If PDFs are scattered in different directories, you can use "Add Files" to select them in batches; if PDFs are already placed in the same folder, it is recommended to use "Import Files from Folder," so you can add all PDFs from that directory to the list at once. After importing, the table will list each file's name, path, extension, creation time, and modification time, making it easy to confirm the processing scope.
The example screenshot has already added 5 records, and the bottom shows the record count as 5. After confirming these are all PDFs that need read-only permissions set, click "Next" at the bottom. If there are files in the list that don't need processing, you can delete them first via the action column to avoid mistakenly adding protection.
Step 3: Set a File Content Read-Only Password, Not an Open Password
After entering step 2 "Set processing options," you first need to distinguish between two password options: "File Open Password" and "File Content Read-Only Password." If you enable the file open password, users need to enter a password every time they open the PDF; if you enable the file content read-only password, it is mainly used to restrict operations like content editing.
The goal of this article is to allow the other party to view PDF content, so the "File Open Password" should remain off. In the screenshot, this switch is in the off state, meeting the requirement for direct opening and viewing.
Next, turn on the "File Content Read-Only Password." In the screenshot, this option is already on, and the password "123456" has been entered. In actual office practice, a more complex password can be set according to internal standards. This password is used for authorization when editing or removing restrictions is needed, and it is recommended to be kept by the document owner.
After completing this step, the core protection logic for the PDF is established: ordinary recipients can open and read it, but cannot edit freely; those with the permission password can perform operations requiring authorization.
Step 4: Retain Print and Copy Text Permissions
Continue setting permissions on the same page. You can see two switches: "Allow printing of PDF file" and "Allow copying of text in PDF." In the screenshot, both switches are in the on state, and the red arrow points to the area related to print settings.
If your goal is "view only, cannot perform any operation," you can close the relevant permissions; but the requirement of this article is "can only view content, and can also print or copy text," so these two options should be enabled. Once enabled, recipients can print out the PDF and copy text content from the document for easy reference, search, or note-taking.
It should be emphasized that allowing text copying does not mean allowing editing of the original PDF. Copy permission mainly affects selecting text from the PDF and copying it elsewhere; editing permission is still controlled by the file content read-only password.
Step 5: Select a Save Location and Execute Batch Processing
After confirming the processing options are correct, click "Next" at the bottom of the page. According to the process flow at the top of the interface, subsequent steps will enter "Set save location" and "Start Processing." It is recommended to output the processed PDFs to a new folder, rather than directly overwriting the original files. This allows you to keep both the original editable version and the read-only version for external distribution.
After setting the save location, enter the start-processing phase. The software will perform the protection operation one by one according to the imported file list. Compared to manually opening each PDF and setting permissions, batch processing can significantly save time and reduce the risk of missed or incorrect settings.
FAQ and Precautions
Why is it not recommended to enable a file open password?
Because the requirement of this article is to allow recipients to view PDF content. If an open password is enabled, the other party will be prompted for a password when opening the file, increasing the reading barrier and making it unsuitable for materials that need widespread distribution.
After setting a read-only password, can the PDF still be searched?
Generally, searchability depends on whether the PDF itself contains recognizable text. What this article sets is editing permission protection, not converting text into images, so it does not affect normal viewing. Whether the copy permission is available depends on whether you enabled "Allow copying of text in PDF."
Why can the processed PDF still be opened?
This is the intended effect. This article sets a file content read-only password, not an open password. Users can open and view normally, but will encounter a permission password prompt when attempting to edit.
Will all PDF readers enforce permissions exactly the same way?
Different PDF software may display permissions differently, but in mainstream PDF tools, protected files typically show an encryption or restricted editing prompt. For official documents, it is recommended to spot-check one or two files with commonly used readers and editors after processing to confirm the effect meets expectations.
Do I need a backup before batch processing?
Backups are recommended. Especially for important PDFs like contracts, quotations, and courseware, it is best to keep the original version and output the processed read-only version to a separate directory for subsequent modification and redistribution.
Summary: Batch Setting PDF Read-Only Permissions for Safer and More Efficient Distribution
Through the "PDF Add Password Protection" feature of HeSoft Doc Batch Tool , you can uniformly set a batch of PDFs to a state where they are viewable, printable, and text-copyable, but not freely editable. The entire process revolves around four key points: importing PDF files, turning off the file open password, turning on the file content read-only password, and enabling print and copy permissions.
For office staff who frequently handle large volumes of PDFs, this batch method can significantly reduce repetitive work. Next time before sending out training materials, contract samples, product brochures, or internal policy documents, you can first use this function to generate a read-only protected version, then distribute it uniformly to clients, colleagues, or students, which not only improves efficiency but also makes file permission management more standardized.
