When a folder contains multiple contracts, reports, study materials, or scanned documents, opening each one and manually merging PDFs is not only time-consuming but also prone to missing files or messing up the order. This article uses HeSoft Doc Batch Tool as an example to demonstrate how to use the PDF tool in office software to batch merge multiple PDF files in the same folder into one PDF file, and explains the effects before and after processing, sorting methods, operational precautions, and common issues. It is suitable for office scenarios that require organizing materials, archiving documents, and submitting complete sets of PDF documents.
In daily office work, we often encounter situations like this: project materials, training materials, a set of contract attachments, or a batch of scanned documents are split into multiple PDF files and placed in the same folder. When it's time to submit, archive, or send them to others, if they remain as multiple independent files, it's inconvenient for the recipient to view and easy for you to lose track of during management. Even more troublesome is that if you manually open them one by one with a reader, drag pages, and then save, not only are the steps repetitive, but problems like omissions, inconsistent order, and chaotic file names may also occur.
The problem this article aims to solve is very clear: How to batch merge multiple PDF files from a folder into a single PDF file. We will use the PDF tool function in the office software " HeSoft Doc Batch Tool " to automatically merge multiple PDFs within a folder, ultimately generating a PDF file named after the folder. For users who frequently handle contracts, information packages, e-book chapters, scans, and report attachments, this type of batch processing method significantly reduces repetitive operations and improves organizing efficiency.
Applicable Scenarios: When do you need to merge PDFs from a folder into one file
Merging multiple PDFs into one is not just about simply "stitching files together." In office collaboration, material organization, and document archiving, it solves many practical problems.
1. Unified Archiving of Project Materials: For example, a project folder contains multiple PDFs such as plans, quotations, contracts, acceptance reports, and supplementary notes. After merging, they form a complete information package, facilitating archiving and retrieval.
2. Organizing Scanned Documents: After scanning paper documents, they are often saved as multiple PDF files. Through batch PDF merging from a folder, the scattered scan results can be organized into a single complete document.
3. Merging Study Materials or E-book Chapters: Course handouts, thesis materials, and English learning resources might be split into multiple PDFs by chapter. Merging them makes reading more continuous and convenient for viewing on tablets or readers.
4. Submitting Contracts and Attachments: If documents like the contract body, authorization letter, business license, and quotation are sent separately, the recipient needs to download and check them one by one. After merging them into a single PDF, both transmission and review become more convenient.
5. Batch Processing Multiple Folders: The feature name shown in the screenshot is "Merge multiple PDF folders into multiple files," which means it is suitable not only for processing a single folder but also for adding multiple PDF folders at once, generating an independent PDF file for each folder separately. The example in this article starts with a single folder to help you understand the complete process.
Effect Preview: Multiple PDFs before processing, one PDF generated after processing
Before the operation, the example folder is named Test folder 4, and it contains several PDF files, such as human-exploration.pdf, learning-tips.pdf, SampleContract-Shuttle.pdf, Voyager-Grand-Tour.pdf, etc. Each file has its own size, indicating that the materials are still stored in a scattered state.
This pre-processing state is very common: when the number of files isn't extremely large, manual processing might seem doable; but once the number of folders increases, or each folder contains a dozen or dozens of PDFs, repeated merging consumes a lot of time.
After processing is complete, a new PDF file is generated within the folder: Test folder 4.pdf. From the screenshot, we can see the merged file size is 12,440 KB. In other words, the multiple PDFs originally scattered within the same folder have been consolidated into a single PDF document. Afterwards, you only need to open, send, or archive this single file.
From the before-and-after comparison, we can see the core value of this operation is: Reducing the management cost of multiple PDF files to the management cost of a single PDF file. Especially in batch office scenarios, this is more stable and time-saving than manual organization file by file.
Operation Steps: Using Office Software to Batch Merge PDFs within a Folder
Following the sequence of screenshots, here is how to complete PDF folder merging in HeSoft Doc Batch Tool . The entire process can be understood as: selecting the function, adding folders, setting the merge order, setting the save location, and starting processing.
Step 1: Enter the PDF Tool and Select "Merge multiple PDF folders into multiple files"
After opening HeSoft Doc Batch Tool , select PDF Tools from the function category on the left. The right side will display feature cards related to PDF batch processing, such as PDF add password protection, PDF add watermark, delete pages from PDF, PDF to Word, PDF to Excel, etc.
Among these functions, find and click "Merge multiple PDF folders into multiple files". As the feature description indicates, it is used for batch merging folders containing PDFs into multiple independent PDF files. For the scenario in this article, we only add one folder, and the result will be a single merged PDF file.
The purpose of this step is to enter the correct PDF merging function interface. Note that you are not simply selecting multiple PDF files here, but selecting "PDF folders." This means the software reads the PDF files within the folder as a unit and then merges them according to the set rules.
Step 2: Add the PDF Folder to be Processed
After entering the function interface, the top of the page shows the current function name "Merge multiple PDF folders into multiple files," and the process is divided into several stages: Select records to process, Set processing options, Set save location, Start processing.
In the first step, "Select records to process," click the "Add Folder" button on the upper right to add the folder containing the PDFs you need to merge to the list. In the screenshot, the folder named Test folder 4 has already been added, and its path is shown as the Test folder 4 folder on the Desktop.
After adding, the list will display information such as serial number, name, path, creation time, and modification time. You can use this information to confirm whether the correct folder has been selected. If you added the wrong one, you can use the delete operation in the interface to remove that entry, or reselect by using "Clear."
The expected result of this step is: the folder to be processed appears in the task list, and the software knows which folder's PDF files to read next. After confirming there are no errors, click the "Next" button at the bottom to go to the processing options settings.
Step 3: Set the PDF Merge Order
After entering "Set processing options," the interface displays "Sort Order." The screenshot offers two options: Merge by name ascending order and Merge by name descending order. The default is Merge by name ascending order.
The sorting method determines the order in which multiple PDFs are merged into the same file. For example, if file names follow a pattern like 01, 02, 03 or A, B, C, choosing "Merge by name ascending order" usually produces a merging result matching the reading order. If your file names are in reverse numerical order, or you want the later files to appear first, you can choose "Merge by name descending order."
This step is crucial because PDF merging is not just about the number of files, but also about the page order. If the order setting does not meet expectations, the merged PDF will be generated successfully, but the reading logic might be confusing. Therefore, it's recommended to check file naming before merging. For contract attachments, report chapters, or scanned pages, it's best to use a unified numbering system beforehand, like 01-Cover.pdf, 02-Table_of_Contents.pdf, 03-Body.pdf. This makes ascending order merging more intuitive.
After completing the settings, click the "Next" button at the bottom to go to the save location settings.
Step 4: Set the Save Location for the Merged PDF
According to the interface flow, the third stage is "Set save location." Although the screenshot doesn't show the specific details of this page, it's clear from the stage name that this step specifies where the processed PDF file will be saved.
When setting the save location, it's recommended to choose an easily identifiable output directory, such as a project archive directory, a temporary Desktop directory, or a dedicated "merged results" folder. This way, after processing, you can quickly find the generated PDF file and avoid mixing it with original files, which could lead to accidental deletion or duplicate sending.
If you are processing multiple folders, it's recommended to keep the output location consistent for a one-time check of all merged results. For the example in this article, the generated file after processing is named Test folder 4.pdf, consistent with the original folder name, making it easy to tell which folder it came from.
Step 5: Start Processing and Check the Results
After setting the save location, you enter the "Start processing" stage. Follow the interface prompts to execute the processing task. The software will read the PDF files in the selected folder and merge them into a single PDF file according to the previously set order (name ascending or name descending).
When processing is finished, open the output directory and check if the target PDF has been generated. In the example, the final output is Test folder 4.pdf, with a file size of 12,440 KB. You can open this PDF and focus on checking the following: whether the file opens normally, whether the page order meets expectations, whether the file count is fully merged, and whether renaming is needed before archiving.
Common Issues and Notes
1. Why is the feature named "Merge multiple PDF folders into multiple files"?
The processing logic of this feature is folder-centric. Multiple PDFs within one folder will be merged into a single PDF. If you add multiple folders at once, each folder will generate a corresponding merged PDF file. Therefore, it handles both the "one folder into one PDF" scenario in this article and batch office tasks of "processing multiple folders to generate multiple PDFs separately."
2. How should I choose the merge order?
If your file names are named according to reading order, like 01, 02, 03, it's recommended to choose "Merge by name ascending order." If you need the files in reverse order, choose "Merge by name descending order." It is best to organize file names before merging, as the order directly impacts the final PDF's reading experience.
3. Why does the file size increase after merging?
The merged PDF contains the content of multiple PDFs from the folder, so the file size usually approaches the sum of the multiple original files' sizes. In the example, after merging multiple PDFs from the original folder, the generated Test folder 4.pdf is 12,440 KB; this is normal.
4. Can I process multiple folders at once?
Judging from the feature name and the "Add Folder" processing method, this function is suitable for batch processing by folder. You can add multiple PDF folders that need merging to the list, allowing the software to generate corresponding merged files for each, thereby reducing repetitive selections and operations.
5. Will the original PDFs be deleted?
The screenshots in this article show the process of merging and generating a new PDF, without displaying any operation to delete the original files. In actual processing, it is recommended to retain the original PDFs. After confirming the merge result is correct, you can decide whether to move or back them up according to your archiving rules.
Conclusion: Turn Repetitive Merging into a Single Operation with a Batch Processing Tool
Merging multiple PDFs from a folder into one may seem like a small task, but in office scenarios involving many files, many folders, or frequent archiving, manual processing consumes significant time. Using office software like HeSoft Doc Batch Tool , you can follow the process of "select PDF Tools — add folder — set sorting — set save location — start processing" to hand over the repetitive labor to the software.
For users who need to organize contracts, scans, study materials, project documents, and report attachments, it is recommended to standardize file naming before merging and then choose the appropriate sorting method. This ensures the generated PDF is not only consolidated but also has a clearer page order. Next time you encounter a folder packed with multiple PDFs, you can directly use the batch merge function to quickly organize scattered files into a single PDF document that is convenient for sending, reading, and archiving.
