How to remove bookmarks from multiple PDF files with one click? Tutorial on batch clearing the left-side table of contents navigation

When multiple PDF files have a left-side bookmark directory, opening and deleting them one by one is not only slow but also prone to omissions. This article focuses on the office scenario of batch removing PDF bookmarks and introduces how to use HeSoft Doc Batch Tool to select the option in the PDF tool to delete bookmarks from PDFs, import multiple PDF files, check the processing list, set the save location, and generate bookmark-free PDFs in a unified manner.

Many people encounter the same problem when organizing PDF files: the document content is fine, but the bookmark panel on the left has too many entries, the hierarchy is too deep, or the bookmark names do not meet publishing requirements. In particular, reports exported from systems, PDFs converted from Word or docx, merged document packages, and downloaded technical documents often carry bookmarks automatically. A single file can be deleted manually, but if a folder contains dozens of PDFs, each one must be opened, the bookmark panel switched, each item deleted, and saved, making the whole process very inefficient.

This tutorial will introduce a method more suitable for office batch processing: use HeSoft Doc Batch Tool to remove all bookmarks from multiple PDF files at once. It is positioned as a batch document processing office software, suitable for handling repetitive and high-volume file tasks. This article will explain the before-and-after effects with screenshots, and clearly explain how to select the function, import files, confirm the list, set the save location, and start processing in the order of the interface, so that you can use it directly after reading.

Applicable scenarios: what problems batch removal of PDF bookmarks can solve

PDF bookmarks usually appear on the left side of the reader and are used to quickly jump to a chapter. They are not the same as the table of contents in the body pages. The table of contents in the body is page content, while bookmarks are the navigation structure inside the PDF. In actual office work, removing PDF bookmarks is common in the following situations.

First, the structure needs to be simplified before sending materials externally. In some reports, the bookmarks on the left may expose the full chapter hierarchy, internal naming, or draft traces, while the body content has already been reviewed and only the navigation information needs to be cleared.

Second, unified standards are needed during batch archiving. In the same project folder, some PDFs have bookmarks and some do not, resulting in inconsistent display after opening. After clearing all bookmarks, the file structure becomes more consistent.

Third, bookmarks in merged or converted PDFs are messy. For example, when multiple doc, docx, pptx, or scanned materials are merged into a PDF, duplicate bookmarks, invalid bookmarks, or incorrect jumps may be created. Deleting them in batch first and then regenerating the table of contents as needed is more convenient than repairing them one by one.

Fourth, there is a need to reduce interference on the left side of the reader. Some long documents have a very large number of bookmark levels, and after opening, the left panel takes up space. After clearing the bookmarks, readers can focus on the page content.

Fifth, it is a preparation before subsequent PDF batch processing. Whether the subsequent step is PDF compression, conversion to Word, conversion to PowerPoint, conversion to JPG images, or modification of metadata, clearing unnecessary bookmarks in advance can make the file cleaner.

Effect preview: multiple levels of PDF bookmarks exist before processing

In the screenshot before processing, the bookmark panel is open on the left side of the PDF reader, and a large number of hierarchical entries can be seen, such as Cover, Results in Brief, Report, Introduction, Background, and so on. Some bookmarks also have more sub-level bookmarks below them, forming a very long navigation tree. The area marked by the red arrow is the PDF bookmark area that needs to be cleared.

If looking at only a single file, manual cleanup may not seem complicated, but when many PDFs have similar structures, deleting them one by one consumes a lot of time. More importantly, manual deletion can easily miss some sub-bookmarks, or one may forget to save a certain file. The advantage of batch processing is that these repetitive steps are completed uniformly by the software.

Effect preview: the bookmark panel on the left is empty after processing

After the processing is complete, reopen the PDF and you can see that the bookmark panel on the left no longer has the original bookmark entries. The document pages still display normally, and the table of contents text, page numbers, and content in the body have not been deleted. In other words, batch removal of bookmarks only affects the navigation structure of the PDF and does not remove the table of contents page or body paragraphs from the pages together.

This is very practical for scenarios that require publishing clean PDFs, hiding the navigation structure, or unifying the archiving format. Users can still read the PDF body, but can no longer jump to chapters through the bookmark tree on the left.

Operation steps: batch clear bookmarks from multiple PDFs with one click

Step 1: Enter the PDF tools category from the tool homepage

After opening HeSoft Doc Batch Tool , first select PDF Tools in the left navigation. This office software organizes different document processing capabilities by category, such as Word Tools, Excel Tools, PowerPoint Tools, Image Tools, and PDF Tools. This time we need to process the bookmark navigation of PDF files, so we need to enter the PDF Tools area.

In the PDF tools list, you can see various batch processing cards, including deleting blank pages in PDFs, PDF optimization and compression, deleting metadata in PDFs, modifying PDF metadata, converting PDF to Word, converting PDF to PowerPoint, converting PDF to JPG images, and so on. Find item number 33, Delete bookmarks in PDF, and the card description shows that it is for batch deleting all bookmarks in PDF files.

The purpose of this step is to ensure that the selected function matches the requirement. If you want to delete the bookmark panel on the left, you should choose Delete bookmarks in PDF, rather than functions related to metadata deletion, compression, or page conversion.

Step 2: Enter the function page and add PDF files

After clicking Delete bookmarks in PDF, you will enter the corresponding wizard page. The page title also shows Delete bookmarks in PDF, indicating that you have entered the correct function. The top provides operation entries such as Add files, Import files from folder, Clear, and More.

If the PDFs to be processed are scattered in different locations, you can click Add files and select the files to be processed one by one. If these PDFs are all in the same folder, it is more recommended to click Import files from folder, so that you can import all PDFs in the folder at once, which is especially suitable for batch deleting bookmarks from many PDFs.

After importing, the files will appear in the list. In the example screenshot, there are 4 records, named 1.pdf, 2.pdf, 3.pdf, and 4.pdf, with paths shown under the D:\test\ directory. The list also displays the extension, creation time, and modification time, making it convenient to verify the file information.

The expected result of this step is that all PDF files whose bookmarks need to be cleared have been added to the processing list. The summary area at the bottom shows the number of records, which can be used to confirm whether any files are missing or extra.

Step 3: Check the processing records to avoid deleting bookmarks from unrelated files by mistake

Batch processing is highly efficient, but it also means that one operation will affect all files in the list. Therefore, before clicking Next, it is recommended to carefully check the processing records. Focus on whether the names and paths are correct, and confirm that these files really need their bookmarks removed.

If there is a PDF in the list that does not need to be processed, you can remove that record using the delete icon in the action column of each row. If too many files are imported, you can also use the filter and sort buttons in the interface to assist with viewing. If the entire list is incorrect, you can use the Clear button to start over.

The purpose of this step is to establish a confirmation stage before batch clearing. The expected result is that only the target PDF files remain in the processing list, thereby reducing the risk of incorrect operations.

Step 4: Click Next to enter the save location settings

After confirming that the list is correct, click Next at the bottom. The page progress bar shows that the current wizard includes three stages: select the records to be processed, set the save location, and start processing. After entering the second stage, you need to set the save location for the processed PDFs.

For office batch processing, it is recommended not to overwrite the original PDFs directly, but to save the output files to a new folder. In this way, the original files still retain their bookmarks, while the processed files are the versions with bookmarks removed. If it is later found that a certain PDF still needs to retain its original bookmarks, it can be restored from the backup files.

The save directory can be named according to the project, such as After clearing bookmarks, PDF release version, Archive without bookmarks, and so on. Clear directory naming can reduce the cost of later searching, especially suitable for multi-person collaboration or batch delivery.

Step 5: Start batch processing and spot-check the output files

After completing the save location settings, enter the start processing stage. After starting, the software will process the PDFs in sequence according to the list and clear all bookmarks in the files. After processing is complete, it is recommended to randomly open several output files for spot checking to confirm that the bookmark panel on the left is empty, and also check whether the body page content is normal.

If the bookmark panel had multiple levels before processing and becomes blank after processing, it means that batch deletion of PDF bookmarks has taken effect. Because the target of this function is bookmark navigation, the text table of contents, images, tables, and body content on the pages should not be deleted as bookmarks.

Frequently asked questions and precautions

Will the table of contents in the PDF pages be deleted together

It will not be deleted together according to bookmark logic. The table of contents in the pages belongs to the body content, while the bookmarks on the left belong to the PDF navigation structure. In the effect image after processing, the table of contents in the page body can still be seen, indicating that what was deleted is the directory tree in the bookmark panel.

Can only some bookmarks be deleted

Judging from the function description in the screenshot, this function is used to batch delete all bookmarks in PDF files. Therefore, it is more suitable for scenarios where all bookmarks need to be cleared at once. If you only want to keep certain bookmarks and delete certain nodes, you need to use a tool that supports fine-grained bookmark editing separately.

Which files will be processed when importing a folder

The interface provides Import files from folder, but after importing, you should still rely on the records actually displayed in the list. Before processing, please check the extension, path, and number of records to ensure that all files in the list are PDF files that need to be processed.

Can the file still be read normally after bookmarks are deleted

Yes. Deleting bookmarks only removes the left navigation entry and does not affect the display of the PDF pages themselves. Readers can still turn pages and read, and can also use the reader's search function to find content.

Why is it recommended to save to a new directory

When batch processing files, keeping the original versions is a prudent approach. If there is no backup after bookmarks are deleted, it will be more troublesome to restore the original navigation structure later. Outputting to a new directory allows both the original files and the bookmark-removed versions to be kept, making comparison and rollback easier.

Summary: turn repetitive PDF bookmark cleanup into a batch office workflow

When removing bookmarks from multiple PDF files, the biggest concern is not that the operation is difficult, but that it is repeated too many times. HeSoft Doc Batch Tool turns this type of repetitive office task into a wizard-based process: select Delete bookmarks in PDF, add files or import from a folder, check the records, set the save location, and then start processing. Compared with opening PDFs one by one and manually deleting bookmarks, this method is more suitable for batch file organization, external publishing, archive filing, and format unification.

If you are processing a batch of PDFs with bookmarks, you can first prepare the folder, and then follow the steps in this article to batch clear the bookmark navigation on the left. After processing is complete, spot-check the output files and confirm that the bookmark panel is empty, and you will obtain a more unified and cleaner version of the PDF files.
