How to batch clear PDF metadata? Office tutorial on deleting author, title, and keywords

The document properties of a PDF file may contain information such as title, author, subject, and keywords. This content may need to be cleared uniformly when sharing files, submitting materials, uploading to systems, or archiving in an enterprise. This article focuses on the office need of clearing PDF metadata in batches, and introduces how to use HeSoft Doc Batch Tool to import multiple PDF files and batch-generate processed files through the "Delete metadata in PDF" feature, avoiding opening PDFs one by one to manually modify properties.

Many users, when organizing PDF files, only focus on whether the page content is correct, but fail to notice that the file properties still contain metadata. For example, PDFs exported from Word, docx, doc, PPT, or other systems may automatically include information such as document title, author name, subject description, keywords, creation time, and application name. When the number of files is small, you can open Adobe Acrobat's document properties to view them manually; but once you need to process dozens of course materials, contract files, report attachments, or project delivery files, manually clearing PDF metadata becomes repetitive, inefficient, and error-prone work.

The problem this article aims to solve is clear: how to batch clear metadata such as author, title, subject, and keywords from multiple PDF files. We will use the office software " HeSoft Doc Batch Tool " for demonstration. Its core value lies in batch processing files and reducing repetitive work, making it suitable for users who often handle office documents such as PDF, Word, Excel, and PowerPoint.

Applicable scenarios: Why clear PDF document properties

PDF metadata usually does not appear in the page body, but it exists in the document properties window, search indexes, document management systems, or file information on some collaboration platforms. For individuals and organizations, clearing this information has several common reasons.

The first is privacy protection. The PDF author field may record a real name, computer account name, or user information set by the generation tool; the subject and keywords may also contain internal project names, course numbers, client codes, and similar content. Before sending files externally, if you do not want this information to be seen, you need to delete attributes such as PDF author and keywords.

The second is document standardization. During enterprise archiving, school material distribution, or training file sharing, PDF title and subject information often comes from different sources with inconsistent formats. After batch clearing, you can prevent outdated titles, incorrect authors, or irrelevant keywords from affecting file display.

The third is batch delivery efficiency. Suppose there are 100 PDFs in a project directory. Opening the properties window one by one and then separately deleting the title, author, subject, and keywords is very costly. Using a batch tool to import a folder and complete the processing at once is more in line with actual office workflows.

The last is submission platform requirements. Some document systems read metadata as the display title after uploading a PDF. If the metadata does not match the filename or actual content, it may cause retrieval confusion. Uniformly deleting metadata can make subsequent management clearer.

Effect preview: What changes before and after clearing

Before clearing: The PDF properties show a specific author and keywords

The screenshot before processing shows the "Document Properties" window in Adobe Acrobat Pro DC. On the "Description" page, you can see that the title, author, subject, and keywords all contain specific content: the title is "Class Notes Packet", the author is "Ian Stone", the subject is "2026 Class Notes Activity", and the keywords include learning, study, pdf, and other information.

This information itself is not necessarily wrong, but if the file needs to be sanitized, redistributed, or entered into a unified archive system, retaining the original author, original subject, and old keywords may not be appropriate. In particular, when many PDFs are generated in batches by tools, the property values may be simulated data, outdated template information, or inaccurate descriptions.

After clearing: The corresponding fields become blank

In the screenshot after processing, when opening the same PDF document properties, you can see that the title, author, subject, and keyword input areas are already empty. In other words, the page content can still be opened and viewed normally, but the common description fields in the document properties have been cleared.

This is the most direct result of the "Delete metadata in PDF" function. For users who need to provide PDF files externally in batches, this processing method is more reliable than manually clearing them one by one and is also easier to verify.

Operation steps: Batch delete PDF author, title, subject, and keywords

Step 1: Open the software and enter the PDF tools category

After launching HeSoft Doc Batch Tool , first look at the left navigation bar. The interface provides several office file processing categories, including Word tools, Excel tools, PowerPoint tools, PDF tools, image tools, video tools, and more. The goal this time is to process PDF files, so you need to select "PDF Tools" on the left.

In the PDF tools list, find "32. Delete metadata in PDF". In the screenshot, the card is selected, and the hover tip explains that this function can batch delete document metadata such as title, author, time, and XMP in PDF files. The "metadata" here is the document property information we need to clear.

Selecting the correct function is very important. You can also see adjacent functions such as "Modify PDF metadata" in the list, but the goal of this tutorial is not to fill in a new author or title for the PDF, but to clear existing attributes, so you should enter "Delete metadata in PDF".

Step 2: Add the PDFs to be processed to the task list

After entering the function page, the software displays a wizard-style workflow. The top steps are "Select records to process", "Set save location", and "Start processing". You are currently on step 1, and you need to first add the files to be processed to the list.

The upper right corner of the page provides two main entry points: "Add Files" and "Import Files from Folder". If the files are scattered, you can use "Add Files" to select them one by one; if multiple PDFs are already in the same directory, using "Import Files from Folder" will be more efficient. In the screenshot, 4 records have already been added, with filenames 1.pdf, 2.pdf, 3.pdf, and 4.pdf, and the paths shown under D:\test\.

After importing, the table lists the file number, name, path, extension, creation time, and modification time. Through these columns, users can determine whether the correct files have been selected. The "Record count: 4" at the bottom indicates that 4 PDFs are ready for batch processing this time. One of the key points of batch office processing is to confirm the input list first, because the subsequent processing will be executed based on this list.

Step 3: Organize the task list to avoid processing errors

Before starting the processing, it is recommended to spend a little time checking the list. If a PDF should not have its metadata cleared, you can click the delete icon in the operation column to remove it; if the entire list is incorrect, you can use "Clear" at the top to re-import. The screenshot also shows "Filter" and "Sort" buttons, which are helpful for reviewing records when there are many files.

The purpose of this step is not to process files, but to reduce the risk of mistakes in the batch task. Especially in scenarios involving contracts, reports, or customer materials, some PDFs may need to retain the original metadata as traceability information, while others need to be cleared. Filtering clearly in advance can avoid later rework.

Step 4: Click Next and set the save location for the processed files

After confirming that the list is correct, click "Next" at the bottom of the page. According to the interface step bar, you will then enter "Set save location". Although the screenshot does not show the specific options on the save location page, the screenshot of the processed PDF properties shows that the result files are in the output directory. This indicates that the workflow supports saving the processed files to a specified location.

It is recommended to choose an output folder different from the original directory, such as "PDF metadata cleanup results", "hesoft-output", or a temporary result folder on the desktop. This has two advantages: first, the original files will not be mixed with the processed results, making comparison easier; second, if you need to reprocess, you can directly return to the original PDF directory.

Step 5: Start processing and check the results

After setting the save location, continue to step 3, "Start processing". The software will process the PDF files one by one according to the task list, delete the document metadata, and generate the processed result files. After processing is complete, it is recommended not to only check whether the files were generated, but also to spot-check the document properties of one or two files.

You can open the result PDF with Adobe Acrobat or another tool that supports viewing PDF properties, go to the "Description" page of "Document Properties", and check whether the title, author, subject, and keywords are empty. When it matches the post-processing screenshot, you can consider the batch clearing of PDF metadata successful.

Common questions and precautions

Will the text on the PDF page be deleted?

No, the page body shown in this article is not treated as metadata and deleted. Metadata is information at the document property level, usually including title, author, subject, keywords, and so on. The before-and-after comparison in the screenshots is also of the document properties window, not the PDF page content. Therefore, this operation is suitable for cleaning file information, not for deleting body watermarks, headers and footers, or page text.

After batch clearing, can the original author and title be restored?

If the original files are not retained, recovery will be more difficult. Therefore, it is recommended to output to a new directory during batch processing and keep the original PDFs. For office teams, retaining the original directory, the output result directory, and processing records is a safer way to manage files.

How to improve accuracy when there are many files?

You can first place the PDFs to be processed into a separate folder, and then use "Import Files from Folder". After importing, check by name, path, and record count, and if necessary use the delete operation in the list to remove files that do not need to be processed. Processing 2 to 3 samples first, confirming the effect, and then processing all files is also a prudent approach.

Does this also apply after converting Word, docx, or doc to PDF?

The applicable target is the PDF file itself. If Word, docx, doc, PPT, or Excel files have already been exported as PDFs, and the PDFs contain properties such as author, title, subject, and keywords, they can be processed using the method in this article. If you want to process the properties of the original Word document, you should use the corresponding Word tool or other document property processing functions.

Summary

Batch clearing PDF metadata is a typical office efficiency need. It is not complicated, but if you rely entirely on manual operation, it consumes a lot of time and makes it easy to miss files or fields. HeSoft Doc Batch Tool uses the "Delete metadata in PDF" function to turn this process into standard steps of importing files, confirming the list, setting the save location, and starting processing, making it suitable for handling attribute information such as author, title, subject, and keywords across multiple PDFs.

If you are preparing to send PDFs externally, organizing archived materials, or uniformly cleaning document properties, it is recommended to first test the effect with a small number of files, and then import the target folder in batches. This ensures that the processing results meet your requirements and fully leverages the value of batch office software in reducing repetitive work and improving efficiency.
