Many contracts, courseware, and reference manuals, when sent to clients or trainees, are intended for viewing only—printing, copying text, or editing the page is not desired. This article explains how to use the "PDF Add Password Protection" feature of HeSoft Doc Batch Tool to set read-only permissions for multiple PDFs at once, disable printing and copying, and illustrates the verification method after setting through before-and-after effect images, suitable for batch protection of PDF files in office scenarios.
In daily office work, PDFs are often used to send course materials, product manuals, quotation plans, internal regulations, contract drafts, and other documents. The advantage of PDFs lies in their stable layout and convenient cross-device viewing. However, if the file lacks permission restrictions, recipients can usually print it directly, copy its text, and even modify the content with editing tools. For materials that need to be distributed externally but should not be redistributed, casually printed, or excerpted, opening each PDF individually to set security permissions is both tedious and prone to being overlooked.
The issue this article aims to solve is clear: Batch-set many PDFs to view-only mode, preventing printing and text copying. The tool used here is the office software " HeSoft Doc Batch Tool ", which is designed for batch file processing. It suits the need to centrally complete repetitive PDF permission setting processes, reducing the time cost of manual, one-by-one operations. The following sections, combined with screenshots, will explain the differences before and after processing, as well as how to complete batch PDF encryption and read-only permission settings in the software.
Applicable Scenarios: Which PDFs Are Suitable for View-Only Settings
If you have dozens or even hundreds of PDFs that need to be uniformly sent to external personnel for viewing, but you do not want them to print, copy text, or edit the content, you can use this method for batch processing. Common scenarios include training institutions distributing electronic handouts, companies sending out product information externally, financial departments distributing read-only reports, administrative departments publishing institutional documents, sales teams sending quotation descriptions, and legal departments sending contract reference drafts.
The focus of such needs is not to set an "open password" for the PDF, because an open password would require every reader to enter a password before viewing, which might not provide a good user experience. A more common practice is to allow the file to be opened and read normally, but restrict operations like printing, copying, and editing. The function in the screenshot precisely uses a "File Content Read-Only Password" to set permissions, allowing users to view the PDF content while disabling permissions for printing and copying text.
Effect Preview: Before Processing, the PDF Can Be Printed, Edited, and Copied
Let's first look at the state before processing. In the screenshot, a PDF file named learning-tips.pdf is opened in Adobe Acrobat Pro DC. It can be seen that text objects on the page are selected, and an editing panel with format, font, size, color, and other options appears on the right. Also, in the "File" menu at the top left, the "Print(P)…" option is clickable. This indicates that before processing, the PDF was not restricted from printing or set to read-only permissions.
For a small number of files, you can manually open PDF software to set permissions individually. However, if there are many files, such as dozens of PDFs in a single folder, manual operation becomes highly inefficient, and each file needs to be checked to ensure the permissions are set successfully. The value of using a batch processing tool lies in its ability to import multiple PDFs at once and uniformly apply the same encryption and permission strategy.
Effect Preview: After Processing, the PDF is Encrypted, Cannot Be Edited, and Cannot Be Printed
After the processing is complete, opening the same PDF again shows the "(Secured)" prompt in the title bar. When a user tries to enter the Edit PDF function, the software pops up a prompt: "This document is secured. Editing is not allowed." This indicates that the file content permissions are active; normal viewing is unaffected, but editing operations are restricted.
Continuing to check the print option in the "File" menu shows that "Print(P)…" has become gray and unusable. This means that while the PDF can be opened to view its content, it cannot be directly printed through the regular print command. For scenarios requiring control over the distribution scope of materials, this permission setting of "viewable but not printable or copyable" aligns better with office needs.
Operation Steps: Batch Setting PDFs to View-Only, No Printing or Copying
Step One: Enter the PDF Tool and Select "PDF Add Password Protection"
After opening HeSoft Doc Batch Tool , select "PDF Tools" from the left category. The main interface will display multiple PDF-related batch functions, such as PDF Add Password Protection, PDF Remove Password Protection, PDF Add Stamp, PDF to Docx, PDF to JPG Picture, etc. The goal here is permission restriction, so select "PDF Add Password Protection."
The description below this function card reads "Batch add protection measures such as file open passwords and read-only passwords to PDFs." As can be seen from the description, it can set not only an open password but also read-only permissions. This article's goal is to make PDFs viewable but not printable or copyable, so the subsequent focus will be on setting the read-only password and related permission switches.
Step Two: Add PDF Files for Batch Processing
After entering the "PDF Add Password Protection" function, the top of the interface provides two entry points: "Add File" and "Import Files from Folder". If you only need to process a few specific PDFs, you can click "Add File"; if all PDFs are already organized in a single folder, it is recommended to use "Import Files from Folder", which allows you to import PDFs from the entire folder at once, improving efficiency.
After file import, the software lists the pending records in a table, including information such as sequence number, name, path, extension, creation time, and modification time. The screenshot shows that 7 PDF files have been imported, such as human-exploration.pdf, learning-tips.pdf, React Hooks.pdf, etc. You can verify the files are all present via this list; if a file is selected by mistake, you can also remove that record using the delete button in the right-side operation column.
Step Three: Set the File Content Read-Only Password and Disable Printing and Copying Permissions
After clicking "Next," you enter the "Set Processing Options" page. Here, there are a few critical switches: File Open Password, File Content Read-Only Password, Allow Printing PDF File, Allow Copying Text from PDF. Based on this article's needs, the File Open Password can remain off, so recipients do not need to enter an open password to view PDF content. Then, turn on "File Content Read-Only Password" and enter a password for permission protection, such as 1234 as shown in the screenshot.
Next, pay attention to two permission switches: "Allow Printing PDF File" and "Allow Copying Text from PDF". If the goal is to make the PDF view-only, unable to print or copy text, do not enable these two options. In the screenshot, these two switches are off, indicating that the processed PDF will not allow printing or copying of text. After setting, click "Next" at the bottom of the page to proceed with setting the save location and start processing.
Step Four: Set Save Location and Start Batch Processing
In the subsequent steps, follow the software's workflow to set the save location for the processed files, and then enter the "Start Processing" stage. Although the screenshot does not show the save location page, the top workflow indicates the complete steps include "Select records to process," "Set processing options," "Set save location," and "Start processing." It is recommended to save the processed files to a new folder to avoid mixing them with the original PDFs, which also facilitates later comparison of permission effects before and after processing.
After processing, you can randomly open a few of the PDFs for verification. The verification method is simple: check in a PDF reading or editing software if the title bar displays "(Secured)", try entering the editing function to see if it prompts that editing is not allowed, and then open the file menu to check if the print function is grayed out and unusable. If these behaviors match the post-processing screenshots above, it means the batch read-only permissions have taken effect.
Common Issues and Precautions
1. What is the difference between a file open password and a file content read-only password?
A file open password controls "whether the file can be opened." If enabled, users need to enter a password to open the PDF. A file content read-only password is more permission-oriented, used to restrict operations like editing, printing, and copying text. This article's goal is "viewable but not printable or copyable," so the emphasis is on using the file content read-only password and disabling print and copy permissions.
2. Why is it recommended to save processed PDFs to a new folder?
When batch processing files, keeping the original files is very important. Outputting encrypted PDFs to a new folder can prevent accidentally overwriting the original files and also makes it easier to reprocess if the settings do not meet expectations. For important files like contracts, financial documents, and teaching handouts, it is recommended to test with a small number of sample documents first before batch processing all files.
3. Are screenshots or photographs absolutely preventable after setting permissions?
PDF permission protection can restrict routine printing, text copying, and editing operations, but it cannot prevent external actions like screen captures or photographing. Therefore, it is suitable for reducing risks of accidental copying, unintended printing, and unauthorized modification in daily office work. However, if files involve highly confidential content, it should be combined with management measures such as access control, watermarks, and distribution records.
4. What should be noted before batch processing?
It is recommended to first confirm that all files to be processed are in PDF format and are not damaged. If some PDFs already have complex permissions or open passwords set, you might need to confirm whether they can be processed normally. After importing files, also check the path and quantity in the list to ensure no missing selections or wrong selections were made.
Summary: Using Batch Tools to Uniformly Restrict PDF Printing and Copying is More Efficient
If you are only processing one PDF, setting permissions manually can be done. But as the number of files increases, opening, setting, and verifying them one by one consumes a lot of time. HeSoft Doc Batch Tool , as office software, has the core value of batching repetitive file processing actions. Through the "PDF Add Password Protection" function, you can import multiple PDFs at once, uniformly set a file content read-only password, and turn off permissions for printing and copying text, keeping the files viewable while reducing the risk of them being printed, copied, and edited.
If you are compiling a batch of PDF materials to be sent externally, you can first gather the files into the same folder, then follow the steps in this article to batch-add read-only protection. After processing, spot-check a few files to confirm the print button is unavailable and editing is restricted, and you can distribute them with confidence.
