How to batch delete the same image from multiple PDFs? Tutorial on removing fixed logos and duplicate illustrations

When the same logo, promotional image, decorative image, or repeated illustration appears on every page of multiple PDFs, there is no need to open each file one by one and delete them manually. This article uses HeSoft Doc Batch Tool as an example to introduce how to import PDFs in batches, select all or specific pages, and use the "Delete fixed images" mode to clean up repeated images, while also explaining the difference between this mode and deleting all images. The tutorial also covers before-and-after effects, file backup, page range settings, and notes on scanned PDFs, making it suitable for data archiving, template cleanup, and producing external documents.

Company historical materials, courseware, e-books, bid attachments, and training documents are often generated from the same set of templates, so the same logo, promotional illustration, outdated标识, or decorative image may repeatedly appear across multiple PDFs. When processing only one file, you can search page by page with a PDF editor; but if dozens of documents all contain the same image, repeatedly opening and saving becomes an inefficient and error-prone task.

This article explains how to use the office software HeSoft Doc Batch Tool to batch delete a specific fixed image from multiple PDFs. This feature provides two operation types: "Delete all images" and "Delete fixed images". The former is suitable for creating a text-only version, while the latter is better for removing only the recurring target image while preserving other illustrations in the document as much as possible. By choosing a reasonable processing scope, you can centrally complete a large number of editing tasks with the same rules.

1. What Is Batch Deletion of Fixed Images in PDFs

A so-called fixed image refers to a specific image that needs to be targeted for cleanup, such as a reused logo, an old promotional image, a template illustration, or other fixed material. The difference from "Delete all images" lies in the processing target:

• Delete all images: Removes image objects within the selected page range, suitable for keeping only text content.
• Delete fixed images: Targets a specific image for cleanup, more suitable when other normal illustrations need to be retained.

Which mode to choose depends on whether the final document still needs to retain other images. If the PDF contains only the target image, or if no images are needed at all, you can directly delete all images; if the pages contain both a logo that needs to be removed and charts, photos, and diagrams that must be preserved, the fixed image mode should be prioritized.

2. Applicable Scenarios

Batch deletion of identical images in PDFs is typically used in the following situations:

1. Cleaning up outdated corporate identifiers: Historical PDFs repeatedly contain logos that are no longer in use, and internal archived copies need to be created.
2. Removing template decorative images: Multiple reports use the same header image or page decoration and need to be uniformly removed before republication.
3. Deleting duplicate promotional materials: Product manuals and course materials contain the same embedded advertisement image, while the main text and other diagrams need to be retained.
4. Organizing outgoing materials: Fixed images are not suitable for appearing in external documents and need to be uniformly removed from a batch of PDFs.
5. Cleaning merged source documents: PDFs exported from the same system all contain fixed illustrations that need standardized processing before archiving.

If the target image appears only on the cover, last page, odd pages, or a specific fixed page number, you can also use the page range options to narrow the processing scope and reduce the impact on other pages.

3. Effect Preview: What Changes Before and After Image Deletion

Page Before Processing

The PDF page in the image below contains a title, body text, page number, and a large illustration. The red arrow points to the image area that needs to be deleted.

In an actual task, this target image may appear in the same position across multiple PDFs, or it may be distributed across different pages. Manual processing requires repeated locating, while batch processing allows multiple files to share the same task settings.

Page After Processing

After the image processing is completed, the target area becomes blank, while the original text, title, and page number remain preserved.

It is important to understand that PDF is a fixed-layout document. After an image is deleted, the text below generally does not automatically move upward, so the page may leave a blank area close to the original image size. This phenomenon does not affect the judgment of the deletion result. If re-layout is still needed, it should be handled afterward using a suitable layout method after the image cleanup is complete.

4. Complete Workflow for Batch Deleting Fixed Images in PDFs

Step 1: Find the Corresponding PDF Office Tool

Launch HeSoft Doc Batch Tool , select "PDF Tools" on the left, and then find "Delete Images in PDF" in the feature list. The feature card description shows that it can batch delete all images or fixed images in PDF files.

This entry handles both types of tasks, so at this point you only need to enter the feature page. Whether to delete all images or fixed images specifically needs to be determined later in the processing options. Do not directly choose another feature just because the target image looks like a watermark; first determine whether it is an image object in the PDF.

Step 2: Add Multiple PDFs to Be Processed

On the "Select records to process" page, you can use "Add Files" to import PDFs one by one or in multiple selection, or use "Import Files from Folder" to centrally add files from a directory.

The task list in the screenshot contains 4 records and displays each file's name, save path, extension, and time information. Before formal processing, check each item carefully, and especially avoid adding already processed result files back into the task, otherwise duplicate versions are likely to be generated.

If the number of imported files is large, you can first organize the source files by file name or path, and then import them uniformly from the folder. When unrelated files are found, use the delete button on the right side of the record to remove them from the current task list. Removal here is mainly used to adjust task records, and the operation should still be confirmed according to the software interface prompts.

After confirming the files are correct, click "Next". The advantage of batch tasks is most obvious at this stage: there is no need to create an operation repeatedly for each PDF, and files that need to use the same rules can simply be added at once.

Step 3: Determine the Page Range Where the Target Image Is Located

On the "Set processing options" page, first select the processing range. The interface provides all pages, the first few pages, the last few pages, odd pages, even pages, and custom.

The page range should be set according to the occurrence pattern of the target fixed image:

• If the target image may appear on every page, select "All pages".
• If the image appears only near the cover, select "First few pages".
• If the image is located on the back cover or at the end of attachments, select "Last few pages".
• If a double-sided template only has images on odd or even pages, select the corresponding page type.
• If the exact page numbers are known, select "Custom".

Reasonably limiting the page range helps reduce the risk of incorrect processing. However, when the page counts or layouts of multiple PDFs are inconsistent, do not judge based on only one file; first spot-check several representative documents.

Step 4: Select "Delete Fixed Images"

In the "Operation type" area, switch the default "Delete all images" to "Delete fixed images". This step determines whether the software clears all images on the pages or processes only the fixed target image.

After selecting fixed image mode, continue to complete the target image-related settings according to the prompts actually shown in the software interface. Because the subsequent controls may differ between versions, this article does not fabricate specific button names; when operating, follow the selection method, explanatory text, and required prompts displayed on the current software page. The core principle is to confirm that the specified image is indeed the target material to be removed from multiple PDFs.

The interface also shows "Enhanced mode" and "Help". If normal mode cannot fully recognize certain PDFs with complex structures, first check the help instructions, and then decide whether to enable enhanced mode. Do not process the only original file directly without testing.

Step 5: Set the Result Save Directory

After completing the options, click "Next". The process bar shows that the subsequent stage is "Set save location". It is recommended to create a new folder with a clear name, such as "PDF Fixed Image Deletion Results", so that output files are stored separately from source files. This makes it easier to compare before and after, and also allows reprocessing if the settings are inappropriate.

If there are many files, the save directory should have sufficient space and should not be mixed with the source directory. For office materials that need to be delivered, you can first save a small number of test results to a temporary directory, and execute the full batch only after verification passes.

Step 6: Start Batch Processing and Spot-Check

After confirming the save settings, enter the "Start processing" stage and execute the task. The software will process multiple PDFs in the list according to the unified page range and operation type. After processing is complete, open the output files for spot-checking, and do not check only one page.

It is recommended to at least check files with a high frequency of the target image, files with the most pages, files with different layouts, and files from scanned sources. Confirm that the fixed image has been deleted, while other charts, photos, text, and page numbers remain normal.

5. How to Choose Between Fixed Image Deletion and Delete All Images

Neither method is absolutely superior; the key is to match the requirement. You can judge according to the following criteria:

• If you want a text-only PDF, choose "Delete all images".
• If you only need to clean up one repeated logo or illustration, choose "Delete fixed images".
• If you cannot confirm which images are in the PDF, first test with a copy.
• The entire page of a scanned PDF may be a single image, so do not delete all images casually.
• When the target image looks similar to other important images, strengthen spot-checking after processing.

If the goal is only to remove obvious duplicate material from the page, fixed image mode usually better meets the requirement of "preserving other content"; if every image is unnecessary, the delete-all setting is more direct.

6. Common Questions and Precautions

1. Why does the page layout not shrink automatically after processing

Unlike word processing formats such as doc and docx, elements on a PDF page are usually placed at fixed coordinates. After an image is deleted, its occupied area leaves a blank space, and other text does not automatically fill the position. This is a normal result.

2. What should I do if the fixed image has inconsistent sizes in different PDFs

It is recommended to first select sample files from different sources for testing. Even if the target material looks visually identical, it may form different internal objects due to compression, cropping, or re-export. Whether it can ultimately be processed as expected should be determined by actual test results.

3. Can I process only the image on the cover

You can narrow the processing scope to the front pages of the document. If the cover page number is fixed, you can also consider a custom range. After setting, still spot-check different PDFs, because some files may contain a table of contents page or no cover.

4. Should enhanced mode be enabled directly when deletion fails

You can first check the help in the interface and test enhanced mode with a copy of a single file. Different PDFs have significant structural differences, so it is safer to verify first and then execute in batch.

5. Why must the original files be retained

Once the fixed image selection, page range, or file list is set incorrectly, it may affect a batch of files. Retaining the source files and outputting the results to a new directory allows you to adjust the rules again at any time and avoid irreversible data loss.

7. Summary

To batch delete the same image from multiple PDFs, there are three key points: correctly import the files to be processed, accurately limit the pages where the target image is located, and select "Delete fixed images" in the operation type. HeSoft Doc Batch Tool centralizes multiple PDFs in the same task, reducing the mechanical operations of opening, locating, deleting, and saving each file one by one.

It is recommended to first select 2 to 3 representative PDFs to create a test task, confirm that the fixed image is removed and other content is not affected, and then import the complete folder to start batch processing. For office materials with unified templates and a large number of files, this workflow can significantly improve organization efficiency and make the output results easier to verify uniformly.
