When multiple PDF files are set with content read-only passwords or permission protection, you may be unable to edit text, add images, crop pages, or modify headers and footers after opening them. This article uses HeSoft Doc Batch Tool as an example to introduce how to batch process multiple PDF files using the PDF password removal feature, allowing the files to be restored to an editable state under legitimate permissions and reducing the repetitive operations of opening and configuring each file individually.
In daily office work, many PDF files are not completely unopenable, but rather cannot be modified after opening. For example, when clicking "Edit PDF" in Adobe Acrobat, the software may prompt that the file is protected and a permissions password is required. Without lifting the content read-only restriction, you cannot modify text, insert images, adjust pages, or continue with subsequent formatting. For just one or two PDFs, manual handling is acceptable; but if a folder contains dozens or even hundreds of PDFs all with the same content read-only password restriction, opening and processing them one by one is extremely time-consuming.
The problem this article aims to solve is: how to batch-remove the content read-only password restriction from many PDF files, making these PDF files modifiable. The office software used here is " HeSoft Doc Batch Tool " as shown in the screenshot. Its positioning is a batch file processing tool for office scenarios, suitable for consolidating repetitive operations on PDF, Word, Excel, PowerPoint, image, and other files for centralized, one-time processing, thereby reducing the number of manual clicks.
It is important to note that the feature page in the screenshot clearly prompts, "This is not password cracking; the software does not have a password cracking function." Therefore, this article discusses removing the password protection settings of a PDF under the premise that you have the file processing permissions, know the relevant password, or the file itself does not require providing content read-only password information. Please do not use this to process files you do not have permission to modify.
Applicable Scenarios: Which PDF Files Are Suitable for Batch Removal of Content Read-Only Restrictions
Batch removal of PDF content read-only restrictions is mainly suitable for the following office scenarios:
- PDFs like contracts, manuals, and courseware requiring secondary editing: The file opens normally, but entering edit mode prompts that it is protected, preventing direct modification of text or images.
- Multiple PDFs from the same template: For example, 1.pdf, 2.pdf, 3.pdf, 4.pdf all have the same permission restrictions and need to be unifiedly removed before modification.
- Need to process permissions before organizing archives: Subsequent operations like adding watermarks, adding page numbers, deleting pages, merging, converting to Word or JPG require ensuring the file is editable or processable first.
- Want to avoid manual operation file by file: If each PDF requires opening individually, entering a password, and saving, the workload increases rapidly with the number of files.
From the screenshot, we can see there are 4 PDF files in the pre-processing folder, namely 1.pdf, 2.pdf, 3.pdf, 4.pdf. This type of batch of files is a typical application object for batch processing tools.
Result Preview: Pre-processing PDF is Protected, Post-processing Can Enter Edit State
Pre-processing: Prompt for Permissions Password after Opening PDF
Before processing, opening 1.pdf in Adobe Acrobat Pro DC shows "(SECURED)" in the title bar. When a user attempts to edit the PDF content, the interface pops up a password prompt: the file "1.pdf" is protected. Please enter a Permissions Password. Without correct handling, the user cannot proceed to modify the text, images, and page objects in the PDF.
This phenomenon usually indicates that the PDF has set permission protection or a content read-only password. This is different from a "Document Open Password": a Document Open Password prevents the file from opening; a content read-only password or permission protection may allow viewing but restrict operations like editing, copying, printing, or page processing. The focus of this article is on batch removing this type of read-only restriction that affects editing.
Post-processing: PDF Content Objects Can Be Selected and Modified
After processing is complete, opening 1.pdf again and entering the Edit PDF mode shows that the "Contents" text on the page can now be selected, and a formatting panel appears on the right. This indicates that the PDF's editing restrictions have been removed, and the user can continue with operations such as text modification, adding text, adding images, and adjusting formatting.
For multiple PDF files, the real time-saver is not just removing the restriction from one file, but being able to import multiple PDFs at once and have the software process them in batches following the same workflow. This avoids switching windows repeatedly between different files and reduces the risk of missed or incorrect processing.
Operation Steps: Using HeSoft Doc Batch Tool to Batch Remove PDF Password Protection
Following the sequence in the screenshots, the steps below explain how to complete the batch removal of PDF content read-only restrictions in HeSoft Doc Batch Tool . The button names in the steps are all from the screenshot interface or can be reasonably inferred from the wizard flow.
Step One: Enter PDF Tools, Select "PDF Remove Password Protection"
After opening HeSoft Doc Batch Tool , select "PDF Tools" in the left navigation bar. The main interface will display multiple PDF-related function cards, such as "PDF Add Password Protection," "PDF Remove Password Protection," "PDF Add Watermark," "PDF to Word," etc. To remove the protection restriction from a PDF, you need to click the 4th function card, "PDF Remove Password Protection".
The purpose of this step is to enter the batch processing wizard specifically designed for removing PDF password protection. Do not mistakenly select "PDF Add Password Protection," which is a feature for adding an open password or read-only password to PDFs; this article requires the opposite direction of processing, i.e., removing protection.
Step Two: Add PDF Files to Process or Import from Folder
After entering the "PDF Remove Password Protection" function, the top of the interface displays the 4 stages of the batch processing wizard: Select records to process, Set processing options, Set save location, Start processing. You are currently at step 1, "Select records to process."
On this page, you can select single or multiple PDFs via "Add Files," or batch-add PDFs from a specific folder to the list using "Import Files from Folder". The screenshot shows 4 files already added: 1.pdf, 2.pdf, 3.pdf, 4.pdf, along with their file paths, extensions, creation times, and modification times. The summary area below shows a record count of 4, indicating these 4 PDFs are all in the queue for processing.
The expected outcome of this step is that all PDFs that need their read-only restrictions removed appear in the list. If you find files added by mistake, you can use the delete icon on the right side of each row to remove them; if there are many files, you can also use the filtering and sorting functions in the interface to assist in verification. After confirming the list is correct, click "Next" at the bottom to enter processing options.
Step Three: Set Processing Options, Distinguish Document Open Password and Content Read-Only Password
After entering step 2, "Set processing options," a yellow prompt appears at the top of the interface: "Please note, this is not password cracking, the software does not have password cracking functionality!" This prompt is very important, indicating this function is used to legally remove known or handleable PDF protection, not to crack unknown passwords.
In the settings area, you can see two items related to passwords:
- Document Open Password: If the PDF requires a password upon opening, you need to provide the corresponding open password here. Otherwise, the software cannot read the file content and thus cannot proceed with processing.
- Content Read-Only Password: Below this item in the screenshot, it shows "No need to provide this information." This means for the content read-only restrictions being addressed this time, the user does not need to fill in extra information.
The purpose of this step is to inform the software whether a Document Open Password is needed to read the files when processing these PDFs. For the scenario in the screenshot, the focus is on removing content read-only restrictions to make the files editable. After confirming the processing options, continue by clicking "Next".
Step Four: Set Save Location to Avoid Risk of Overwriting Original Files
Step 3 of the wizard is "Set save location." Although the screenshot does not expand the specific save location page, the process bar clearly shows this is a necessary step in the batch processing flow. It is recommended to choose a new output folder at this stage, such as "Read-Only Restriction Removed" or "Editable PDFs," allowing you to keep the original PDFs as a backup.
The purpose of setting the save location is to provide a clear output path for the processed PDFs. For office files, especially important documents like contracts, textbooks, and archives, it is not recommended to directly overwrite the original files without a backup. Keeping the originals allows for quick comparison during subsequent verification and avoids situations where recovery is impossible due to operational errors.
Step Five: Start Processing and Check Results
After completing the save location settings, proceed to step 4, "Start processing." After clicking start, HeSoft Doc Batch Tool will process the PDFs one by one according to the list and output the unprotected files to the specified location. After processing is complete, it is recommended to randomly open one or several of the PDFs and enter editing mode using Adobe Acrobat or another PDF editor to check.
If, like the post-processing screenshot, the text objects in the PDF can be selected and the formatting panel is available, it indicates the file has been restored to an editable state. For the 4 batch-processed files, you can also spot-check them individually to confirm that the content read-only restriction has been successfully removed from all.
FAQ and Notes
1. Is this function for cracking PDF passwords?
No. The operation interface clearly prompts, "This is not password cracking, the software does not have a password cracking function." If a file has an unknown open password, the software cannot crack it for you. You need to provide the necessary Document Open Password under the premise of having legal permission, or process PDFs that do not require providing content read-only password information.
2. What is the difference between a Document Open Password and a Content Read-Only Password?
The Document Open Password affects "whether the PDF can be opened." Without the open password, the file might not be viewable. The Content Read-Only Password or Permissions Password affects "whether you can edit, copy, print, or modify pages." The scenario in this article's screenshots is where the file can be opened, but editing requires a permissions password, thus being closer to a content permission restriction issue.
3. Why is it recommended to back up original files before batch processing?
PDF files are typically formal document formats, and many files have archival value. While batch processing improves efficiency, incorrect file selection or improper save path settings can lead to management chaos. Outputting the processed results to a new folder allows you to retain both the original version and the editable version, facilitating traceability.
4. Will I definitely be able to edit perfectly after removing restrictions?
After removing content read-only restrictions, the PDF can enter an editing state, but the specific editing experience also depends on the PDF itself. If the PDF is a scanned document, the page content might be images rather than editable text; if the text uses special fonts, font substitution might occur during modification. Removing protection addresses permission restrictions, not OCR text recognition or layout reconstruction.
5. Can I import an entire folder at once?
Yes. The top of the screenshot shows a "Import Files from Folder" button, which is suitable for processing a large number of PDFs. For scenarios with many files, this is more efficient than clicking "Add Files" one by one. After importing, remember to check the list to avoid adding PDFs that do not need processing.
Summary: Use Batch Processing to Reduce Repetitive Operations, Making PDF Modification More Efficient
When numerous PDF files have content read-only password restrictions, opening and processing them individually is not only time-consuming but also prone to omissions. By using the "PDF Remove Password Protection" feature in HeSoft Doc Batch Tool , you can add multiple PDFs to a processing list at once, follow the wizard to complete steps for processing options, save location, and starting the process, thereby quickly obtaining editable PDF files.
If you are organizing a batch of contracts, documents, courseware, or manuals and these PDFs prompt that they are protected when editing, you can follow the steps in this article to batch remove the read-only restrictions first, then proceed with subsequent modifications, watermarking, converting to Word, or deleting pages. It is recommended to start testing with a small number of files, confirm the effect, and then process the complete folder. This ensures safety while maximizing the efficiency advantage of the office software's batch file processing capabilities.
