This article focuses on the scenario of uniformly adding a perforation seal to multiple PDF contracts, bids, and archival documents. It explains how to use the "PDF Add Stamp" feature in HeSoft Doc Batch Tool to import multiple PDF files at once, select the perforation seal type, set the processing range, stamp image, position, and scaling effect, and ultimately batch-generate PDFs with perforation seals. The tutorial includes before-and-after comparisons and operational screenshots, making it suitable for office workers who need to reduce repetitive stamping tasks and improve document processing efficiency.
In office scenarios such as contract archiving, bidding documents, financial materials, training handouts, and internal approval documents, a specific but time-consuming problem often arises: there are multiple PDF files, each with multiple pages, and all need a cross-page seal added to the page edges. If you open each PDF individually and adjust the stamp position page by page, it is not only inefficient but also prone to issues like inconsistent stamp positioning, missing stamps on certain pages, and disorganized file saving.
This article aims to solve the problem of "batch adding cross-page seals to many PDFs." Using the PDF batch processing capabilities of the office software " HeSoft Doc Batch Tool ", you can import multiple PDFs at once, set the cross-page seal image, page range, stamp position, and scaling effect within a single workflow, and then output the processed PDF files uniformly. For users who frequently handle PDF contracts, PDF agreements, PDF bid documents, and PDF proof materials, this type of batch stamping process can significantly reduce repetitive work.
Applicable Scenarios: When is it suitable to batch add cross-page seals to PDFs?
Batch adding cross-page seals is mainly suitable for office scenarios with a large number of files, relatively uniform layout requirements, and the need to show continuity or completeness at the page edges. For example, dozens of PDF contracts under one project each require a cross-page seal on the right edge; or a batch of training materials, archive files, and approval attachments need uniformly stamped PDF stamps before sending, printing, or archiving.
As seen in the screenshot, the files to be processed are multiple PDF files named 1.pdf, 2.pdf, 3.pdf, and 4.pdf. This indicates the task is not about processing a single PDF but performing batch operations on multiple PDFs in a folder.
Using traditional methods, you would need to open 1.pdf, 2.pdf, 3.pdf, and 4.pdf one by one, insert the stamp, drag it into position, and save the file. The more files there are, the more obvious the repetitive operations become. However, using HeSoft Doc Batch Tool , these PDFs can be processed uniformly as a batch task, aligning better with the office software's purpose of "processing files in batches, reducing repetitive work, and improving efficiency."
Effect Preview: Before processing, the PDF lacks a cross-page seal
When opening the PDF file before processing, the right edge of the page is a blank area with no cross-page seal. The screenshot uses an arrow to mark the approximate location where the cross-page seal needs to be added, which is the right edge area of the PDF page. For multi-page PDFs, the cross-page seal typically needs to be distributed across page edges to create a continuous stamping effect.
This pre-processing effect illustrates two key points: First, the content of the PDF file itself already exists, and the body text does not need re-editing; second, the goal of this operation is to add a stamp element to the PDF page edges, not to modify text content, split pages, or convert formats. Therefore, you should select functions related to "PDF Add Stamp" or "PDF Batch Stamping."
Effect Preview: After processing, a cross-page seal appears on the PDF edge
After processing is complete, opening the generated PDF reveals that a portion of a purple stamp has appeared on the right edge of the page. Because the cross-page seal effect was chosen, the stamp is not placed entirely in the center of a single page but close to the page edge, creating a continuous visual stamping effect across multiple pages. The position pointed to by the arrow in the screenshot is the added cross-page seal area.
From the post-processing effect, the stamp position is concentrated on the right side of the page, consistent with common cross-page seal practices. For batch processing multiple PDFs, as long as the parameters set initially are consistent, subsequent PDFs can automatically have stamps added according to the same rule, avoiding manual adjustments for each file.
Step 1: Enter the PDF Tools and select the PDF Add Stamp function
After opening HeSoft Doc Batch Tool , you can see multiple tool categories on the left, such as Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, etc. The target files for this operation are PDFs, so you need to enter the "PDF 工具" category. The interface lists several PDF-related functions, including PDF Add Watermark, PDF Add Page Margins, PDF to Word, PDF to JPG Image, etc.
According to the screenshot, you should select the 7th item, "PDF 添加图章". The function description is "批量给 PDF 添加图章", which directly corresponds to the need to batch add cross-page seals to PDFs. The screenshot also contains the prompt "批量给 PDF 添加图章", indicating that this step is the key to entering the correct functional entry point.
The purpose of this step is to find the PDF batch processing function related to stamping from the toolbox. The expected result is to enter the "PDF 添加图章" task interface, after which you can import multiple PDF files and set stamp parameters.
Step 2: Add the multiple PDF files to be processed
After entering the "PDF 添加图章" interface, the top shows the operation flow divided into four steps: Select records to process, Set processing options, Set save location, Start processing. The first step is to import the PDF files to be processed. The upper right of the interface provides two entry points: "添加文件" and "从文件夹中导入文件", along with "清空" and "更多" buttons.
If there are only a few PDFs, you can click "添加文件" to select specific files; if the PDFs are all in the same folder, using "从文件夹中导入文件" is more suitable for batch processing. The screenshot shows 4 PDF files have been imported, with the list displaying information like serial number, name, path, extension, creation time, and modification time. The files include 1.pdf, 2.pdf, 3.pdf, and 4.pdf, with the summary showing a record count of 4.
The purpose of this step is to add the PDFs needing batch cross-page seals to the task list. The expected result is that all PDF records to be processed appear in the software's table. You can check the file names, paths, and count in the list to confirm no files are missed and no wrong files are imported. If a certain PDF doesn't need processing, you can use the delete operation on its row to remove it; if you imported the wrong batch of files, you can also use "清空" to clear and re-import.
Step 3: Set the processing range to all pages
After importing the files, click "下一步" at the bottom to enter the second step, "设置处理选项". As shown in the screenshot, the processing range area provides multiple options, including "所有页面", "最前面的几个页面", "最末尾的几个页面", "奇数页面", "偶数页面", "自定义", etc. This time we are adding a cross-page seal, and typically we want every page to participate in the stamping effect, so "所有页面" is selected in the screenshot.
The advantage of selecting "所有页面" is avoiding missing stamps on middle or end pages, which is especially suitable for multi-page PDFs like contracts, bids, and data compilations. If certain business needs require only the first few pages or specific pages to have a stamp, you can adjust it according to the range options provided in the interface, but for this example, the recommended setting for batch adding cross-page seals is all pages.
Step 4: Select the stamp type as Cross-Page and import the stamp image
In the "图章类型" area, the interface provides two options: "普通" and "骑缝". "普通" stamps are more suitable for placing a complete seal in a fixed position on a single page, while cross-page seals are suitable for placing on the PDF page edges to create a continuous stamping effect across multiple pages. The screenshot shows "骑缝" has been selected, which is the core setting of this tutorial.
Next, you need to click "选择文件" in the "图章图片" area to import the image file to be used as the cross-page seal. The screenshot shows "已选择 1 个文件", indicating the stamp image has been successfully added. It is recommended to prepare a clear stamp image with a suitable background in advance, avoiding images that are too small (leading to blurriness when enlarged) or excessive blank edges that affect the edge-hugging effect of the cross-page seal.
The purpose of this step is to tell the software that the stamp to be added is not a regular page stamp but a cross-page seal, and to specify the specific stamp image file. The expected result is that the "骑缝" option is selected, and the stamp image area shows that a file has been selected.
Step 5: Set the cross-page seal position and display effect
Further down on the same settings page, you can see the "位置" and "效果" areas. The position area offers "固定位置" and "自定义位置". In the screenshot, "固定位置" is selected, and the middle-right position is chosen in the position indicator box. For cross-page seals, the right edge is a common position, and the post-processing effect also shows the stamp impression located on the right edge of the PDF page.
The effects area shows several setting items, including "旋转角度（顺时针）", "裁剪边缘空白", "不透明程度", and "缩小或放大". In the screenshot, "缩小或放大" is enabled, and the slider is used to adjust the stamp size. This setting is important because the size of the cross-page seal image may not perfectly match the PDF page dimensions; scaling ensures the stamp is both clearly visible and does not obscure the body text.
When setting the position and effect, it's recommended to prioritize two things: first, the stamp should be close to the edge, meeting the visual requirements of a cross-page seal; second, it must not obscure the body text, page numbers, or important signature areas. After completing these settings, click "下一步" to enter the save location settings, then follow the flow to "开始处理".
Common Problems and Notes
1. Why choose Cross-Page instead of a Regular stamp? Regular stamps are suitable for displaying a complete seal impression on a single page, while cross-page seals are better for continuous stamping on the edges of multi-page PDFs. If the goal is a cross-page effect for contracts or materials, you should choose "骑缝".
2. Should I back up the original PDFs before batch processing? Backing up is recommended. Batch processing affects multiple PDF files at once; saving the original files beforehand reduces the risk of operational errors and makes it convenient to compare effects before and after processing.
3. How should the stamp image be prepared? It is recommended to use a clear stamp image, avoiding low resolution. If the image has excessive blank edges, it may affect the edge-fitting effect; this can be adjusted using the software's settings for cropping blank edges, scaling, etc.
4. Is it normal not to see the complete stamp impression after adding? For a cross-page seal, it is a common effect for a single page to only show a part of the stamp. The key point is that when viewing multiple pages consecutively, the page edges form a continuous visual for the cross-page seal.
Summary
Batch adding cross-page seals to many PDFs is essentially a typical batch processing requirement for office files. Using HeSoft Doc Batch Tool , the "PDF 添加图章" function allows you to complete the entire workflow: from importing multiple PDFs, selecting the cross-page seal type, setting all pages, importing the stamp image, adjusting the fixed position and scaling effect, to final batch output.
Compared to manually stamping PDFs one by one, batch processing significantly reduces repetitive clicks and manual adjustment time, and can also improve the consistency of stamp positioning. It is recommended that users test the effect with a small number of PDFs before formal processing, confirming the position, size, and page range are correct, before importing the entire batch of files for processing.
