PDF files that can be opened but not edited are a common issue for many office workers handling contracts, materials, courseware, and archived files. This article focuses on PDF content read-only password restrictions and demonstrates how to use the PDF remove password protection feature in HeSoft Doc Batch Tool to batch queue multiple PDF files, set processing options and save location, and process them uniformly to restore the files to an editable state.
You may have encountered a situation: there is a batch of PDFs in a folder that all seem to open normally, but as soon as you enter editing mode, a prompt pops up asking for a permission password. At this point, the PDFs are not just simple ordinary documents; they have some form of permission protection or content read-only restriction. For those who only need to view them, this is a minor issue, but for office workers who need to modify content, replace images, adjust tables of contents, or add/delete pages, this directly blocks subsequent work.
If there is only one PDF, manual processing might be acceptable; but if, as shown in the screenshot, there are multiple files like 1.pdf, 2.pdf, 3.pdf, 4.pdf, or even more, opening each one, removing the restriction individually, and saving each file becomes inefficient, repetitive labor. This article introduces a more suitable method for batch office work: using HeSoft Doc Batch Tool , through the "PDF Remove Password Protection" function, to batch-remove PDF content read-only password restrictions, restoring editability to multiple PDF files under the premise of legal authorization.
HeSoft Doc Batch Tool is an office software whose key value lies in batch processing files, reducing repetitive clicks, and enhancing document processing efficiency. It is not merely a PDF reader but a toolbox that centralizes various document processing tasks, suitable for handling common office files like PDF, Word, Excel, PowerPoint, and images.
Applicable Scenario: When a PDF can be viewed but not edited, this is how you can handle it
The method in this article is mainly applicable to situations where "a PDF can be opened, but editing is restricted." Common manifestations include: a password window popping up after clicking to edit PDF; some edit buttons being unavailable; page text being unselectable and unmodifiable; functions like adding text, adding images, and cropping pages being restricted. The prompt from Adobe Acrobat in the screenshot is a typical example: the file "1.pdf" is protected and requires a permission password to be entered.
These scenarios are common in the following tasks:
- Batch modification of PDF materials: For example, needing to uniformly replace titles, dates, footers, or images in training materials, product manuals, or course handouts.
- Batch organization of historical PDF archives: Old files had permissions set, and subsequently need to be merged, split, have pages deleted, or be converted in format.
- Preprocessing before batch conversion: Intending to convert PDFs to Word, PowerPoint, TXT, or JPG, but permission restrictions affect subsequent processing.
- Uniform processing of files from the same source: PDFs exported from the same department or system often have consistent settings, making them suitable for being imported and processed uniformly at one time.
It must be emphasized that this article does not discuss cracking unknown passwords. The software page in the screenshot also clearly indicates: This is not a password cracking tool; the software does not have the function to crack passwords. Please only process PDF files that you are authorized to modify.
Effect Preview: The change from protected to editable
Before Processing: Multiple PDFs awaiting processing in the folder
As seen from the screenshot before processing, the files awaiting processing include 1.pdf, 2.pdf, 3.pdf, 4.pdf. They are all in PDF format. If verified and processed manually one by one, it requires frequently opening files and switching software windows, consuming a lot of time.

When the number of such files increases, the advantages of batch processing become more apparent. For instance, manually processing 4 files might not be too complicated, but for 40 or 400 files, a batch processing workflow must be relied upon, otherwise ensuring efficiency and accuracy is difficult.
Before Processing: Protection prompt appears upon entering editing mode
After opening 1.pdf, the Adobe Acrobat interface shows that this file is encrypted. When the user attempts to edit, the system pops up a "Password" window, indicating the file is protected and requires the entry of a permission password. This means the content modification permissions for the current PDF are restricted.

This restriction is usually not due to file corruption but results from the PDF's permission settings. To continue editing, the corresponding password protection needs to be removed or unlocked.
After Processing: Text objects can be selected, and the editing panel is available
After batch processing, when opening 1.pdf again, you can see that selection boxes have appeared around the text areas on the page, and the formatting panel on the right can also normally adjust font, font size, color, and paragraph style. This state indicates that the PDF is now editable, and subsequent modification work can proceed.

For a batch of files, as long as all PDFs in the same batch are successfully processed, the permission removal work that originally required repetitive execution can be compressed into a single import, single setup, and single processing run.
Operating Steps: Batch remove PDF content read-only password protection
Step 1: Open the software and enter the PDF Tools category
After starting HeSoft Doc Batch Tool , you can see functional categories on the left, including Home, Task Flows, All Tools, File Name, Folder Name, File Sorting, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, etc. Since this article deals with PDF files, you need to first click on "PDF Tools" on the left.
After entering PDF Tools, the main area lists functions in the form of cards. The screenshot shows that "PDF Remove Password Protection" is located at the 4th card, indicating it is a function specifically designed to remove open passwords and read-only passwords from PDF files. Click on this card to enter the processing wizard.

The expected result of this step is to enter the "PDF Remove Password Protection" function page, not to stay on the tool list page. Selecting the correct function is critical because the PDF Tools also contain functions like adding passwords, adding watermarks, deleting pages, and converting formats, which operate in different directions.
Step 2: Import the PDF files to be processed
After entering the function page, the current function name "PDF Remove Password Protection" is displayed at the top of the interface. Buttons like "Add Files," "Import Files from Folder," "Clear," and "More" are provided on the upper right. For a small number of files, you can click "Add Files"; for a large number of PDFs in a folder, "Import Files from Folder" is recommended.
In the screenshot, 4 PDF files have been imported. The list shows the sequence number, name, path, extension, creation time, modification time, and actions. Each row represents a PDF file about to be processed, and the summary at the bottom shows the record count is 4.

After importing, perform a verification: confirm that the file names are correct, the paths come from the target folder, and the extensions are pdf. If files that do not need processing are found, they can be removed via the delete icon in the action column on the right; if the entire import list is incorrect, you can use "Clear" to reselect.
Step 3: Click Next and configure password-related options
After confirming the file list, click "Next" at the bottom. The software enters step 2, "Set Processing Options." This page is very critical because the password type of the PDF might be different, leading to different processing methods.
In the screenshot, there is a prompt at the top of the page: "Please note, this is not a password cracking tool; the software does not have the function to crack passwords!" This illustrates that if a PDF is a file with a completely unknown password, one should not expect the software to crack it. Below are two sections: "File Open Password" and "File Content Read-Only Password." The "File Content Read-Only Password" section indicates "No need to provide this information," which aligns with the goal of this article: when removing content read-only restrictions, the user does not need to fill in additional information in this field.

If your PDF also requires an open password to open it initially, you need to provide the relevant information in the "File Open Password" section. If the file opens normally but is only restricted during editing, you typically just need to focus on the content read-only restriction. After completing the settings, continue by clicking "Next."
Step 4: Set the output location, retaining the original files
The wizard flow shows the 3rd step as "Set Save Location." It is recommended not to directly overwrite the original file directory with the batch processing results, especially when dealing with contracts, official materials, or archived documents. A safer approach is to create a new output folder to save the PDFs after protection removal.
Doing this has three benefits: First, the original files will not be compromised, allowing rollback if problems occur; second, it is easier to compare files before and after processing; third, for team collaboration, this clearly distinguishes the "original protected version" from the "editable version." When batch processing files, clear save paths can reduce post-sorting costs.
Step 5: Start processing and verify the editable status
After setting the save location, proceed to step 4, "Start Processing." Upon clicking start processing, the software will process these PDFs sequentially according to the import list. After processing is complete, it is recommended not to just check if the files were generated but also to open a few of them to verify the actual effect.
The verification method is simple: open the processed PDF with Adobe Acrobat, enter Edit PDF mode, and check if the permission password prompt still pops up; try to select a text object and see if the format editing panel on the right is available. If consistent with the screenshot after processing, it indicates the read-only restriction removal was successful.
Common Issues or Precautions
1. Why does the PDF open but still show as "Encrypted"?
PDF encryption and permission control can be divided into different levels. Some passwords control opening, while others control permissions like editing, copying, and printing. Therefore, just because a file opens does not mean it is necessarily editable. In the screenshot, the file could be opened, but a permission password was needed for editing.
2. Must all PDFs have the same password during batch processing?
It cannot be confirmed from the screenshot whether the software supports setting different passwords for different files, so one should not make assumptions casually. A safer approach is: first process a batch of PDFs from the same source and with the same permission settings together; if files come from different sources, it is recommended to import them in separate batches to facilitate troubleshooting.
3. What if the file is still not editable after processing?
First, confirm whether the file was processed successfully and whether you have opened the new file in the output directory, not the original file. Next, check if the PDF is a scanned image version. If the page content itself is an image, even if permissions are removed, it cannot be edited directly like normal text; it requires OCR or other recognition workflows.
4. Can the processed PDF be further converted to Word or docx?
In the PDF tools list of HeSoft Doc Batch Tool , functions like "PDF to Word" can be seen. After removing the content read-only restriction, if further editing and layout adjustments are needed, it can be converted to a Word format like docx or doc as required. However, the conversion effect will be influenced by the original structure of the PDF.
5. Will batch-erasing password protection affect the content of PDF pages?
The goal of this function is to remove password protection or permission restrictions, not to modify the main content of the pages. To be safe, it is still recommended to test with 1 or 2 files before formal batch processing. After confirming that the page content, layout, and editable status meet expectations, process all files.
Summary: Leave repetitive PDF unlocking tasks to batch office software
When multiple PDFs prompt they are encrypted and cannot be edited, the least efficient method is to open, input, and save each one individually. For office workers, this type of repetitive labor not only takes up time but is also prone to errors. Using the "PDF Remove Password Protection" function of HeSoft Doc Batch Tool , you can add multiple PDFs to a processing list at once and, following the wizard to complete option settings and save configuration, process them uniformly.
If you have a batch of PDFs that can be viewed but not modified, and you possess legal processing permissions, it is recommended to first prepare a backup of the original files, then follow the steps in this article to import them into the software for batch processing. After processing is complete, open the output files to check. As long as the text and objects can be normally selected and edited, you can proceed with subsequent modifications, organization, conversion, or archiving tasks.
