When a folder contains multiple PDF files such as contracts, reports, and study materials, opening, copying, or manually merging them one by one is not only time-consuming but also prone to missing the file order. This article explains how to use HeSoft Doc Batch Tool to batch merge multiple PDFs in a PDF folder into a single PDF file in name order, suitable for office scenarios such as document archiving, project delivery, and contract consolidation.
In daily office work, many materials do not exist as a complete PDF, but are scattered in the same folder: for example, multiple scanned copies, multiple chapter materials, different versions of instruction documents, contract attachments, project acceptance materials, etc. If you need to organize these PDFs into one complete file, manual merging often involves repeated adding, adjusting the order, and saving as a new file; the more files there are, the easier it is to make mistakes.
The problem this article aims to solve is very clear: Batch merge multiple PDF files in a folder into a single PDF file. Using the PDF batch processing function in HeSoft Doc Batch Tool , you can add a folder as the processing object. The software will merge multiple PDFs within that folder into one independent PDF based on the set sorting method. This kind of operation is very practical for office scenarios that require batch file processing, reducing repetitive work, and improving sorting efficiency.
Applicable Scenarios: When is it suitable to merge PDFs in a folder into one PDF
Batch merging PDFs is not just as simple as "stitching a few files together"; it usually corresponds to the process of material archiving and delivery. The following types of scenarios are particularly common:
- Project material archiving: A project folder contains multiple PDFs like proposals, quotations, contracts, acceptance sheets, and reports, which need to be merged into one master file for easy archiving.
- Contract and attachment summarization: The main contract body, supplementary agreements, signature pages, and scanned attachments are saved as separate PDFs and need to be organized into one complete PDF before submission.
- Study material compilation: Multiple PDF chapters, lecture notes, papers, or English materials are stored separately; merging them makes reading and transferring more convenient.
- Scanned document merging: Scanners or mobile scanning apps may generate multiple PDFs page by page or batch by batch, which need to be combined into a single document.
- Batch folder processing: If you have multiple folders, each representing a set of materials, you can use a similar approach to generate a corresponding merged PDF for each folder.
Compared to online tools or manual editing, the advantage of using desktop office software for batch processing is: the processing path is clear, it is suitable for local folders, folders can be added in one go, and it better meets the efficiency requirements for material organization for enterprises or individuals.
Effect Preview: What changes before and after processing
Before Processing: A folder containing multiple PDF files
As seen in the screenshot before processing, the example folder is named Test folder 4, which contains multiple PDF files, including human-exploration.pdf, learning-tips.pdf, SampleContract-Shuttle.pdf, Voyager-Grand-Tour.pdf, etc. Each PDF has its own file size, indicating that these files were originally stored separately.

If processed using traditional methods, you would need to select PDFs one by one, manually import them into a merging tool, confirm the order, and export the new file. This is manageable when the number of files is small, but once there are dozens of PDFs or multiple folders, it significantly impacts office efficiency.
After Processing: A merged PDF file is generated
After processing is complete, the multiple PDFs in the folder are merged into a single PDF file. In the screenshot, you can see the output result is Test folder 4.pdf, with a file size of 12,440 KB. This means the multiple PDF materials originally in the folder have been organized into one independent PDF document.

This output method is very suitable for archiving: the file name directly corresponds to the original folder name, making it easy to identify the source and convenient for subsequent sending, uploading, or backup.
Operation Steps: Using HeSoft Doc Batch Tool to Merge PDFs in a Folder
Step 1: Enter PDF Tools, select "Merge multiple PDF folders into multiple files"
After opening HeSoft Doc Batch Tool , select PDF Tools from the left function category. In the PDF Tools list, find and click "Merge multiple PDF folders into multiple files".

The "multiple PDF folders" in this function name indicates that it supports processing by folder; "merge into multiple files" means each folder will generate a corresponding merged PDF. If only one folder is added this time, then you will eventually get one merged PDF file. This perfectly suits the goal of this article – merging multiple PDFs in a folder into one PDF.
Step 2: Add the PDF folder to be processed
After entering the function page, the interface will follow a wizard-style process. The first step is Select records to process. Click the Add Folder button at the top right to choose the target folder containing multiple PDF files.

After successfully adding, the folder will appear in the list. The screenshot shows the added record as Test folder 4, and you can also see the folder's path, creation time, and modification time. After confirming the folder is correct, click Next at the bottom to continue.
Note here: what is being added is a "folder," not individual PDF files. The software will perform the merge processing on the PDF content within that folder. Therefore, before operation, it is recommended to put the PDFs you want to merge into the same folder and remove any PDFs that should not be included.
Step 3: Set the PDF merging order
After entering the second step, Set processing options, you can choose the sorting method. The screenshot provides two options: Merge in ascending order by name and Merge in descending order by name.

The sorting method will affect the page order in the final PDF. It is generally recommended to prefix the file names with numbers before processing, such as 01-Cover.pdf, 02-Table of Contents.pdf, 03-Main Text.pdf, 04-Appendix.pdf. This way, when choosing "Merge in ascending order by name," the software will merge them from smallest to largest based on file name, resulting in a more stable reading order in the output PDF.
If your files are named in reverse order or need to be sorted in descending order, you can also choose "Merge in descending order by name." After confirming the sorting method, click Next.
Step 4: Set the save location and start processing
From the process flow at the top of the interface, you can see that the subsequent steps include Set save location and Start processing. Continue following the software wizard to select the save location for the merged PDF, then proceed to the start processing step.
Since this function handles batches of folders, it is recommended to distinguish the output directory from the original PDF folder, for example, creating a new "Merged Results" folder. This makes it easy to compare files before and after processing and prevents accidental deletion or overwriting of original materials. After confirming the save location, execute the process and wait for the software to complete the merging.
Step 5: Check if the output PDF meets expectations
After processing is complete, open the output directory to check. In the example, the resulting file is Test folder 4.pdf, consistent with the original folder name. You can focus on checking three aspects: First, was only one PDF generated? Second, does the file size correspond to the combined size of multiple original PDFs? Third, after opening the PDF, is the page order consistent with the previously set ascending or descending name order?
Common Questions and Notes
1. Why is it recommended to organize file names first?
Because the processing options shown in the screenshot mainly involve merging by name in ascending or descending order. File names directly affect the merging order. If file names are unnumbered, the system's name-based sorting might not match manual expectations. To make the PDF merging order more controllable, it is recommended to use prefixes like 01, 02, 03.
2. How many PDFs will be generated from one folder?
According to the function logic, one folder will be merged to produce one corresponding PDF file. If multiple folders are added, each folder will generate a separate PDF; if only one folder is added, one PDF will be generated. This is why the function is suitable for batch-organizing multiple sets of materials.
3. Can I add individual PDFs directly?
The function entry shown in this article is "Merge multiple PDF folders into multiple files," and the operation screenshots highlight "Add Folder." Therefore, this tutorial suggests operating by folder: put the PDFs you want to merge into the same folder first, then add that folder for processing.
4. Do I need to back up original files before merging?
It is recommended to keep the original PDF folder, especially for important files like contracts, financial materials, and scanned documents. Although batch processing can improve efficiency, retaining the original files is helpful for subsequent tracking, supplementation, and reordering.
5. How is the output file name identified?
From the post-processing screenshot, the output PDF uses the folder name as the file name, such as Test folder 4.pdf. This naming convention makes it easy to correspond the merged result with the original folder, suitable for batch archiving.
Summary: Batch Merge PDF Folders for More Efficient Material Organization
Merging multiple PDFs in a folder into one PDF is a very high-frequency organization need in office work. Using HeSoft Doc Batch Tool , you can use the "Merge multiple PDF folders into multiple files" function within "PDF Tools" to add a folder as the processing object, set merging in ascending or descending order by name, then follow the wizard to set the save location and start processing.
Compared to manual merging one by one, this method is more suitable for batch file processing, reducing repetitive operations and the risk of missing files or sequence errors. If you often need to organize contracts, reports, scanned documents, or project materials, it is recommended to standardize file naming first, then use this function to batch generate merged PDFs, making file archiving and delivery clearer and more efficient.
