How to batch delete the same image from multiple PDFs? A tutorial on cleaning fixed logos and duplicate images

When the same logo, outdated branding, advertising images, or fixed decorative images repeatedly appear across multiple PDFs, there is no need to delete all images or manually search through each document. This article explains how to use HeSoft Doc Batch Tool to select the files to process and limit the page range via the "Delete Images in PDF" feature, and set the operation type to "Delete Fixed Images". This allows you to centrally clean up the target images while preserving other illustrations in the body as much as possible, making it suitable for content revisions, brand logo updates, and batch archiving.

When corporate materials are revised, brand logos are updated, or course documents are republished, it is often necessary to delete the same image from a batch of PDFs. For example, the headers of dozens of product manuals may all use an old logo, the same promotional image may appear repeatedly across multiple training files, or a batch of archived PDFs may contain an outdated fixed identifier. Opening each file one by one and searching page by page is time-consuming and also prone to missed deletions when there are many pages.

This kind of task is not the same as "deleting all images from a PDF." Illustrations in the body text, statistical charts, and diagrams still need to be kept; what really needs to be cleaned up is only that repeatedly occurring fixed image. HeSoft Doc Batch Tool is an office software focused on batch file processing, and its "Delete Images from PDF" feature provides two operation types: "Delete all images" and "Delete fixed images." By correctly selecting the processing scope and operation type, you can reduce the workload of repeatedly processing PDFs one by one.

1. Applicable scenarios for batch deletion of fixed images from PDFs

"Fixed images" usually refer to images that appear repeatedly in one or more PDFs, have a consistent appearance, and need to be cleaned up as a specific target. Common applications include the following.

• Remove old corporate logos: After a company completes a brand upgrade, it may need to delete old identifiers from historical brochures, policy documents, or product descriptions.
• Clean up duplicate advertising images: The same event poster or promotional image has been inserted into multiple materials, and after the event ends it needs to be removed centrally.
• Delete fixed header and footer images: Every page or some pages of a PDF carry the same icon, and you want to delete the icon while retaining the header text and body images.
• Handle leftover template elements: Multiple PDFs exported from the same template may contain unified decorative images, background corner marks, or placeholder images that need to be cleaned up before archiving.
• Organize teaching and exam materials: Multiple exam papers, handouts, or electronic textbooks contain the same prompt image, and you want to keep the question illustrations while removing only the specified image.

If all images in the target PDFs are no longer needed, directly choosing "Delete all images" will be simpler; if only one specific image is allowed to be deleted, then you must use "Delete fixed images" to avoid removing body illustrations as well.

2. Preview of effects before and after processing

1. Before processing: the page contains the image to be deleted

The screenshot below shows a PDF page before processing. The title, paragraphs, page number, and image exist at the same time, and the red arrow points to the image in the middle of the page that needs to be cleaned up. In an actual batch task, the target may also be a logo, icon, or other repeated image that appears on multiple pages or in multiple files.

This sample PDF has 180 pages in total, and the screenshot shows page 133. For files with many pages, manually locating the image itself requires repeatedly paging through the document; if multiple PDFs also need to be processed, manual methods can hardly balance speed and accuracy.

2. After processing: the target location becomes blank

The page after processing is as follows. The image that was originally in the middle of the page has disappeared, while the title, body text, text below the image, and page number remain. The area indicated by the red arrow appears blank, indicating that the target image object has been removed.

PDF is a fixed-layout file format. After deleting an image, the following content generally does not automatically reflow upward as it would in a Word or DOCX document, so the image location may leave a blank space. If the fixed image is in a header, footer, or page corner, usually only the corresponding area becomes empty after deletion; if the image is in the middle of the body text, the blank space will be more noticeable.

It should also be noted that the example images are mainly used to show the page effect after the image has been deleted. When performing "Delete fixed images," you should further confirm in the results whether the target image has disappeared and whether other non-target images on the same page remain.

3. Workflow for batch deleting the same image from multiple PDFs

Step 1: Find the "Delete Images from PDF" feature

Open HeSoft Doc Batch Tool , and in the category bar on the left select "PDF Tools." The main interface will list various PDF-related functions. Find item 15, "Delete Images from PDF," and click to enter.

From the description on the feature card, you can see that this tool is used to batch delete all images or fixed images from PDF files. Therefore, there is no need to open PDFs one by one to clean up repeated logos; you only need to add the relevant files to the same batch task and then set the rules uniformly.

Step 2: Add multiple PDFs to be processed at once

After entering the feature page, the first step in the workflow is "Select records to process." If only a small number of scattered files need to be processed, you can click "Add files"; if the PDFs to be processed are all in the same directory, you can use "Import files from folder."

The task list in the screenshot already contains 1.pdf, 2.pdf, 3.pdf, and 4.pdf, for a total of 4 records. The list also shows the file path, extension, creation time, and modification time, which helps verify the source before processing. After importing, it is recommended to complete the following checks:

1. Confirm that the file extension is PDF to avoid selecting other files with similar names by mistake.
2. Confirm that the path belongs to the current project or current version to avoid processing copies in old directories.
3. Confirm that the number of records matches the number of files planned for processing.
4. If a file is added by mistake, use the delete icon on the right side of that record to remove it.

If the entire batch of files needs to be reselected, you can click "Clear" above. After confirming that the list is correct, click "Next" at the bottom to enter the processing rule settings.

Step 3: Set the processing scope based on where the fixed image appears

The second step interface first provides a "Processing scope" setting, including all pages, the first few pages, the last few pages, odd pages, even pages, and custom.

The processing scope should be determined according to where the fixed image actually appears:

• If the target logo may appear on any page of the document, select "All pages."
• If the fixed image appears only near the cover or table of contents, select the first few pages.
• If the target image is on the back cover, appendix, or disclaimer page, select the last few pages.
• If odd and even pages use different templates, you can select odd pages or even pages.
• If you know for certain that the image appears only on specified page numbers, you can select "Custom" to narrow the processing scope.

Reasonably limiting the page range can make the processing rules more targeted and also facilitate subsequent checking. If you are not sure which pages contain the target image, using "All pages" is less likely to miss anything, but after processing you should perform more comprehensive spot checks.

Step 4: Select "Delete fixed images"

In the "Operation type" area, you can see two radio options: "Delete all images" and "Delete fixed images." The goal of this task is to remove a specific logo or the same repeated image, so you should switch the operation type to "Delete fixed images."

This step is very critical. If you mistakenly select "Delete all images," body illustrations, photos, statistical charts, and other images within the selected page range may also be deleted. For documents where other images must be retained, it is recommended to check the radio option again before proceeding to the next stage.

After selecting the fixed image processing method, provide the target image that needs to be identified and deleted according to the interface prompts subsequently displayed by the software, and confirm that the selected image is the object that appears repeatedly in the PDF. Because the target image setting area may be displayed differently depending on the operation type in different software versions, in actual operation refer to the current software interface. Do not substitute an image that looks similar but is not from the same source, as this may affect the matching result.

Step 5: Determine whether to use enhanced mode

The settings page also displays an "Enhanced mode" switch and provides a "Help" entry. Generally, you can first process one test file using the default method. If normal mode does not recognize the target image, or if the same image uses a relatively special internal storage structure in the PDF, you can check the help instructions before trying enhanced mode.

It is not recommended to directly process all official files without testing. A more prudent approach is to copy one representative PDF, check the deletion of the target image, the retention of non-target images, and whether the page display is normal, and then decide on the final settings.

Step 6: Set the output location and execute the task

After completing the processing scope, operation type, and target image settings, click "Next." From the workflow shown at the top, you can see that the following steps include "Set save location" and "Start processing." It is recommended to create a separate output directory, such as "Old logo removed" or "Fixed image cleanup results," and not overwrite the original PDFs directly when running the task for the first time.

After confirming the save location and starting the task, the software will process the multiple PDFs in the list one by one according to the same rules. Compared with manually deleting from each file, the advantages of batch processing lie not only in saving clicks, but also in allowing multiple files to use a consistent page range and recognition target, reducing the problem of different files being processed under different standards.

Step 7: Check both the deletion effect and the retention effect

After processing is complete, the check should not only look at whether the target image has disappeared, but also confirm whether the images that should have been retained are intact. The following spot-check methods are recommended:

1. Open a page known to contain the fixed image and confirm that the target logo or repeated image has been deleted.
2. Check other illustrations on the same page to confirm that they have not been removed by mistake.
3. Check the same location in different PDFs to confirm that the batch rules were indeed applied to every file.
4. Check the first page, a middle page, and the last page to confirm that page numbers, text, and page counts are normal.
5. Keep the original task files, and do not archive or deliver them until the spot checks pass.

4. Common reasons why fixed image deletion is incomplete

1. They look the same, but are actually different internally

Logos in different PDFs may look identical to the naked eye, but may differ in size, resolution, compression method, color, or cropping range. The matching effect for fixed images may be affected by these differences. Therefore, you should prioritize selecting an image that is consistent with the target source in the PDF, and test it with representative files first.

2. The target is not an ordinary image object

Some logos may be composed of vector paths, text outlines, or a combination of multiple graphic objects. Although they visually look like an image, internally they may not be saved as an ordinary bitmap. "Delete Images from PDF" mainly targets recognizable image objects. When encountering a complex structure, you can check the enhanced mode help and verify the result.

3. The page range is set too narrowly

If only the first few pages are selected, but the fixed image also appears in the body text or at the end of the document, then targets outside the range will not be processed. Before starting the task, first confirm the distribution pattern of the fixed image. If uncertain, you can select all pages.

4. An inappropriate reference image is used

If the reference image has been re-captured, framed, scaled, cropped, or color-adjusted, it may differ significantly from the original image in the PDF. When preparing the target image, try to keep the main subject and boundaries consistent, and avoid including irrelevant background.

5. A logo on a scanned page cannot be deleted separately

A scanned PDF may merge the entire page of text, logo, and images into one large image. In this case, the logo is not an independent object, and the fixed image deletion feature may not be able to separate it from the full-page scanned image. Before processing, you can try selecting the page text; if the text also cannot be selected individually, verify with a copy first.

5. Precautions

• Back up the original files first: Batch tasks affect many files, and keeping the source PDFs can avoid situations where incorrect rule settings leave no way to recover.
• Test on a small scale first: Selecting one or two representative PDFs for testing is more prudent than directly processing all materials.
• Distinguish between fixed images and all images: When body illustrations need to be retained, you can only select "Delete fixed images."
• Do not rely only on file size: After deleting a small logo, the PDF file size may not change noticeably, so the page display result should be used as the standard.
• Check file permissions: Encrypted, permission-protected, or damaged PDFs may not be read normally, so first confirm that the file can be opened and processed.
• Keep a separate output directory: Store the processing results separately from the original files for easier comparison, spot checking, and rollback.

6. Summary

When facing the same logo, icon, or repeated image across multiple PDFs, manually deleting it page by page is slow and prone to omissions. Using HeSoft Doc Batch Tool , you can first import multiple PDFs at once, then uniformly define the page range, set the operation type to "Delete fixed images," and then set the output location and run the task centrally.

This batch file processing method is especially suitable for corporate material revisions, historical file archiving, teaching material organization, and fixed identifier cleanup. It is recommended to first select one representative PDF as a test sample, confirm that the target image has been deleted and other images remain, and then apply the verified settings to all files, thereby improving efficiency while reducing the risk of accidental deletion.
