When multiple long PDFs need to be split simultaneously, opening them one by one and manually exporting pages is very inefficient. This article explains how to use HeSoft Doc Batch Tool to split multiple PDFs with many pages into multiple smaller PDFs by page count in one batch, and generate independent result folders for each original file. The article includes before-and-after effects, specific operation steps, and notes, suitable for office scenarios such as reports, scanned documents, and document compilations.
Many people encounter a typical issue when organizing PDF documents: the files are not just one, but a batch; the page count is not a few, but dozens or even hundreds. For example, within the same project, there are multiple lengthy PDF reports, and later, they need to be split into smaller PDFs based on a fixed number of pages to be sent to colleagues, uploaded to a system, or archived by page segments. If using a standard PDF reader to open them individually and save segments one by one, the operation steps are not only repetitive but also prone to incomplete results due to incorrect page number selections.
The core problem this article aims to solve is: How to batch-split multiple large PDF files with many pages into multiple smaller files at once. The tool we use is the office software " HeSoft Doc Batch Tool ". As seen in the screenshot, this software provides a dedicated PDF tools category and includes the "Split PDF into multiple files" function. Its core value is not single-file editing, but rather catering to batch processing scenarios, helping users reduce repetitive labor, unify processing rules, and improve document organization efficiency.
Applicable Scenarios: Which office tasks are suitable for batch-splitting long PDFs
Project Document Splitting. Project deliverables, audit documents, and technical documentation are often compiled in PDF format, with a single file potentially containing a cover page, table of contents, body text, and appendices. Splitting a long PDF into multiple smaller PDFs allows for distribution by chapter, page segment, or reviewer.
Scanned File Organization. Scanned paper materials often form one continuous PDF. If a scanned file contains multiple forms, contracts, or supporting documents, splitting them into smaller files during subsequent archiving makes them much clearer.
Batch System Upload. Some business systems have limits on individual file size or page count, and overly large PDFs have a higher upload failure rate. After splitting by page count, smaller PDFs are more likely to pass system restrictions.
Document Reading and Sharing. A PDF with dozens of pages is not suitable for frequent forwarding via instant messaging tools, nor is it conducive for the recipient to quickly locate content. After splitting, you can send only the necessary parts, reducing communication costs.
Unified Processing of Multiple PDFs. When multiple PDFs in a folder need to be split according to the same rules, batch processing is more reliable than handling them one by one. HeSoft Doc Batch Tool incorporates multiple PDFs into a single task through an import list and processing wizard.
Result Preview: From large PDF files to organized small PDFs
Before Processing: Directory contains multiple PDFs to be split
The folder before processing contained 5 PDF files, named 1.pdf to 5.pdf. They are all pending processing objects, suitable for batch execution using the same set of splitting rules.
Upon opening one of the PDFs, the reader shows that the current page is 1, with a total of 77 pages. For such a long PDF, if it were to be split every 2 pages, manually extracting pages would require repeatedly selecting page ranges, which is highly unsuitable for batch scenarios.
After Processing: Result folders generated respectively for original PDFs
After the process completed, folders named 1, 2, 3, 4, 5 appeared in the output directory. Each folder corresponds to an original PDF, and this output structure prevents the split results from different PDFs from being confused with one another. For batch tasks, the clarity of results is often as important as the processing speed.
After Processing: Long PDF becomes multiple small PDFs arranged by sequence number
Upon entering one of the result folders, you can see the split small PDFs named with two digits, such as 01.pdf, 02.pdf, 03.pdf, up to 39.pdf. Files named in sequence facilitate identifying the order later, and are also convenient for batch selection, compression, or sending.
Steps: Splitting multiple large PDF files at once
Step 1: Locate the split function in PDF Tools
Open HeSoft Doc Batch Tool and select "PDF Tools" from the left navigation bar. The main area will display several PDF batch processing function cards, including PDF Merge, PDF Encrypt, PDF Add Watermark, and more. The one to use this time is "4. Split PDF into multiple files". The function card is indicated in the screenshot, showing it supports splitting a PDF into multiple files by page count or file quantity.
After selecting this function, the software enters a step-by-step task interface. Unlike temporary manual handling, the wizard-based process is more suitable for batch office tasks: first confirm which files to process, then set the splitting rules, then set the save location, and finally start the unified processing.
Step 2: Import the PDFs to be split and check the list
After entering the function page, you are currently on step 1, "Select records to process". Buttons for "Add Files" and "Import Files from Folder" can be seen at the top right of the interface. If the PDFs to be processed are scattered in different locations, use "Add Files" to select them; if multiple PDFs are concentrated in a single folder, use "Import Files from Folder" to improve import efficiency.
In the example, 5 records have been imported. The table displays information such as Name, Path, Extension, Creation Time, and Modification Time. It is advisable to focus on checking two points here: first, whether all names are the PDFs that need to be split; second, whether the paths point to the correct folder. Because batch processing executes the same rules on all records in the list, if files are imported incorrectly, they will also be processed subsequently.
If you find files in the list that do not need processing, you can use the delete icon in the action column to remove them; to re-import, you can use "Clear". When the number of files is very large, "Filter" and "Sort" can help view and organize the records. After confirming the record count at the bottom of the list is correct, click "Next".
Step 3: Choose "Max pages per PDF" and enter the page count
Upon entering step 2, "Set processing options", the required field "Split Method" is visible. The screenshot shows two selectable options: "Max pages per PDF" and "Average split into several files". The example selected "Max pages per PDF" and entered 2 in the input box.
The meaning of this setting is: each split smaller PDF will contain at most 2 pages. Assuming an original PDF has 77 pages, the software will split from the first page, grouping 2 pages each time, until the last remaining pages also generate a PDF. Thus, it is reasonable that 39 small PDFs appear in the output. For users, the advantage of this method is that the rule is clear, and all PDFs are processed according to the same page count upper limit.
If you need a split every 5 pages, change the number to 5; if you need every 10 pages, enter 10. The smaller the page count setting, the more files generated; the larger the page count setting, the fewer files. It is recommended to choose based on actual usage; for example, set it smaller for email sending and larger for internal archiving.
Step 4: Set the save location to avoid overwriting and mixing
After setting the split method, continue by clicking "Next" to enter the "Set save location" step in the workflow. Although the provided screenshot does not show the details of the save location page, the step bar already shows this is part of the split task. For batch splitting of PDFs, the save location is crucial. It is recommended to select a new output directory, such as a folder created by project name or date.
Doing so has three benefits: First, the original PDFs and the split PDFs won't be mixed together; second, the result folders corresponding to each original file are easier to locate; third, if you need to re-split with a different page count, you can simply delete the output directory and process again without affecting the original materials.
Step 5: Proceed to start processing and check the output results
After confirming the save location, enter step 4, "Start Processing". Before starting, it is recommended to double-check the processing rules, especially whether the number for "Max pages per PDF" is correct. Execute the process after confirming there are no errors, and the software will batch-split the multiple PDFs in the imported list.
After the processing is complete, you can go to the output directory to view the results. According to the result screenshots, each original PDF will generate a corresponding folder, which contains small PDFs arranged by sequence number. It is recommended to randomly open a few small PDFs to check the page order and confirm the split results meet expectations.
Frequently Asked Questions and Notes
1. What is the difference between "Max pages per PDF" and "Average split into several files"?
The former splits by a page count upper limit, e.g., every 2 pages into one file; the latter splits towards a target number of files, e.g., wanting to split evenly into several files. The example used in this article splits by a page count upper limit, suitable for scenarios where you need to control the page count of each small PDF.
2. Why are folders generated after processing instead of all PDFs being placed directly together?
From the result screenshots, the output generated corresponding folders based on the original PDFs. This keeps the split results of each original file independent, especially suitable for preventing confusion when processing multiple PDFs at once.
3. Why are the split file names 01.pdf, 02.pdf?
Naming by sequence number helps maintain file order. For content split from a long PDF, order is crucial, and numbered names help users quickly judge the sequence.
4. What if the splitting rule is set incorrectly?
It is recommended to keep the original PDFs and save the output results to a separate directory. If you find the page count setting inappropriate, you can return to the split function, adjust the page count, and process again.
5. Is it suitable for processing many PDFs?
From the design of the import list and "Import Files from Folder" feature, it is clear this function is intended for batch processing scenarios. For a large number of PDFs, batch import and unified settings can significantly reduce repetitive operations.
Summary: Delegate repetitive PDF splitting work to a batch processing tool
When multiple long PDFs need splitting, the most time-consuming part isn't a single technical action, but the constant repetition of opening files, selecting page ranges, saving documents, and checking naming. HeSoft Doc Batch Tool focuses these repetitive steps into a single wizard workflow via its "Split PDF into multiple files" function: select files, set rules, set save location, and start processing.
If you are dealing with PDF reports or scanned materials of dozens or hundreds of pages, it is recommended to first organize the pending folder, then follow the steps in this article to import the PDFs, select "Max pages per PDF", set the output directory, and execute in batch. This not only saves significant time but also makes the split results more standardized, easier to deliver, and archive.
