In scenarios involving the security and confidentiality management of PDFs, sometimes for privacy protection, we need to restrict others from accessing and viewing these PDF documents. The PDF format is widely used globally due to its excellent compatibility and stability, but by default, PDFs cannot independently set encryption to prevent others from accessing them. We need to manually apply encryption protection to set an open password for PDF documents, so that only users who know the password can open and view them. This effectively protects the security of information when transmitting or storing important documents such as commercially sensitive files or personal privacy information.
Here I'll show you a method: when you have many PDF documents and need to prevent others from opening and viewing them, you can batch set a unified open password to efficiently enhance document security. Let's follow along and see how it works!

Steps to Batch Prevent Others from Opening PDF Documents
1. Open [ HeSoft Doc Batch Tool ], and click [PDF Tools] - [PDF Add Password Protection].
2. Choose a method from [Add Files] or [Import Files from Folder] to add the PDF documents you want to encrypt. You can also directly drag and drop files into the import area below. After confirming the files are correct, click Next.
3. In the settings options interface, enable the [File Open Password] toggle, and enter the password you want to use to encrypt the PDF below. If you want to allow others to open and view the document but prevent them from modifying its contents, you can enable the [File Content Read-Only Password] toggle and set a read-only password for the PDF. Finally, click Next again, then click Browse, and select a save location for the new file.
4. After processing is complete, click the red path to view the successfully encrypted PDF document.
Frequently Asked Questions
Q: Is the file privacy and security of this tool guaranteed? I wanted to use software to batch add passwords before, but I saw that some online tools require uploading, so I was afraid it wasn't safe and didn't proceed.
A: Importing files with online tools takes several minutes of waiting, but this small tool can import hundreds of files in just 1 second. Moreover, all file processing is done locally, with no file uploading involved at any point, thus protecting users' privacy information.
Q: How fast is the processing speed? How long does it take to set passwords for hundreds of PDF documents?
A: Since all file processing is done locally, importing files takes no time. The final processing time is related to your computer's configuration. Generally speaking, adding passwords to hundreds of PDF files takes at most a dozen seconds.
Q: Is the software easy to use in practice? I don't like overly complex things, as learning also takes time and effort.
A: Open the tool - Add files - Set password - Wait for processing to complete. That's the entire workflow. The interface is intuitive, simple, and easy to understand.
Q: Are there any other features? For example, what if I want others to view the document but not modify its contents?
A: Yes, there is. On the password setting screen, simply do not set an open password, and instead set a read-only password. Also, adding document passwords is not limited to PDF files; it also supports Word, Excel, and PPT files.
Q: I tried it out and it feels pretty good, but I still have issues that require merging and splitting PDFs to solve. Are you considering adding new features?
A: Of course! HeSoft Doc Batch Tool is currently under continuous updates, and more useful new features will be rolled out subsequently, all dedicated to helping everyone solve problems encountered at work and improve work efficiency in diverse office scenarios.
