When there are many large images and they need to be uniformly split into multiple small JPG images, manual cropping can be very time-consuming and often leads to issues like disorganized file naming and inconsistent dimensions. This article explains how to use HeSoft Doc Batch Tool to batch split large images: First, select "Split Image into Multiple Small Images" in the image tool, then batch add JPG files, next choose "Fixed Width and Height Split" and enter the width and height of each small image, and finally set the save location and start the process. From the before-and-after screenshots, it can be seen that the original multiple images are automatically output as corresponding folders and sequentially numbered small images.
If you often organize image materials, you're likely familiar with this repetitive task: a batch of large images needs to be cut into multiple JPG thumbnails, each divided by the same width and height. It seems like simple cropping, but when actually operating, you'll find the whole process—opening images, selecting areas, saving, naming, and moving to the next—is very time-consuming. Especially when dealing with many images and strict size requirements, manual processing is not only slow but also prone to missed cuts, incorrect cuts, and inconsistent naming.
This article introduces a more office-suitable approach: using HeSoft Doc Batch Tool to batch split multiple large images into many smaller ones. This software is an office tool whose core value lies in batch file processing, helping users reduce repetitive work and improve efficiency. Using screenshots, the following will explain the effects before and after processing, and how to uniformly cut JPG images into specified-sized thumbnails through "Fixed Width & Height Splitting".
Applicable Scenarios: What Office Problems Can Batch Splitting Large Images Solve?
Batch splitting large images isn't just an image editing requirement; it often occurs during file organization and material standardization. For example, when content operators organize image libraries, they need to split a batch of large images into multiple reusable thumbnails; when training document authors create courseware, they need to split large screenshots into partial images for insertion; during design collaboration, scene images need to be cut into several material blocks; data collation personnel might also need to slice images by fixed sizes for subsequent analysis or annotation.
These scenarios share a common point: identical processing rules and numerous files. As long as the rules are clear, there's no need for manual repetitive execution. Using a batch processing tool, you set a fixed width and height once, and the software automatically splits all images by the same standard. This method is particularly suitable for the batch organization of common image files like JPG and JPEG, and also fits a workflow of testing with a few samples first before large-scale execution.
From an efficiency perspective, the benefits of batch image splitting are mainly in three areas: first, reducing repetitive operations, no need to open and crop individual files; second, unifying output specifications, avoiding size deviations caused by manual dragging; third, making the resulting structure clearer, where the split thumbnails are managed in folders and sequence numbers, facilitating subsequent checking, uploading, or reprocessing.
Effect Preview: What Changes Occur Between Original Images and Split Results?
Before processing, there are 5 pending JPG images in the folder, named 1.jpg, 2.jpg, 3.jpg, 4.jpg, and 5.jpg. They are all complete large images, with content including landscapes, architecture, natural scenes, etc. If you want to split all these images into thumbnails of fixed width and height, manual processing would generate many repetitive steps.
After processing, five folders—1, 2, 3, 4, 5—appear in the output directory. Each folder corresponds to the split results of one original image. In the screenshot, the 2nd folder is selected, and below it shows that multiple JPG thumbnails were generated within this folder, with filenames ranging from 01.jpg, 02.jpg, 03.jpg, all the way to 28.jpg. That means the original 2.jpg was automatically cut into 28 smaller image files.
This output format is highly suitable for batch tasks. You don't need to determine which thumbnail came from which original image among a pile of scattered files, because the results are already split into different folders based on the originals. For subsequent archiving, uploading, or manual review, this structure is much clearer than manual saving.
Operation Steps: Batch Splitting Images by Fixed Width and Height
Following the sequence of software operation screenshots, here's how to complete the entire process. The software name in the screenshots is " HeSoft Doc Batch Tool ", with an interface using categories on the left, function cards on the right, and wizard-style processing steps, suitable for office users who prefer not to write scripts but need batch file processing.
Step 1: Open the Image Tool and Select the Split Large Image Function
After launching the software, select "Image Tools" in the left toolbar. The main area will display batch functions related to images, including adding watermarks, image effects enhancement, and image format conversion. The function needed here is "Split Image into Multiple Small Images". In the screenshot, this function is listed as the 3rd item, showing the description "Batch split a large image into many small images".
After selecting this function, the software will enter a dedicated image-splitting process. The expected result of this step is entering the correct batch processing page, not one for format conversion or image enhancement. Since this article's goal is "splitting", confirm when selecting the function that its name includes "Split into Multiple Small Images".
Step 2: Add the JPG Images to Be Split into the Processing List
After entering the split function, the top of the page provides options to "Add Files" and "Import Files from Folder". If you've already placed all the original images in the same directory, it's recommended to use "Import Files from Folder" to import multiple images at once; if you're just temporarily selecting a few, you can use "Add Files".
After importing, the images will appear in a table. The screenshot shows 5 records, all with jpg extensions, paths pointing to 1.jpg through 5.jpg in the D drive test directory. The table also shows creation and modification times for users to verify correct files. The "Summary" at the bottom shows 5 records, indicating this batch task will process 5 images.
At this step, it's advisable not to rush to the next step but to first check the file list. If there are files that don't need processing, they can be deleted via the operation column; if the list is empty or incorrectly imported, you can click "Clear" and re-select. A key feature of batch processing is that once started, it acts on multiple records simultaneously, so confirming the list before processing is crucial.
Step 3: Set Splitting Method to Fixed Width & Height Splitting
After confirming the image list, click "Next" at the bottom to enter "Set Processing Options". On this page, "Splitting Method" is visible, including "Average Splitting" and "Fixed Width & Height Splitting". Since this article requires splitting by fixed width and height, select "Fixed Width & Height Splitting".
After selection, you need to enter the "Width of each small image" and "Height of each small image". In the screenshot, the width is 200 and the height is 200, indicating the target size for each output thumbnail is 200×200. This parameter will apply to all images in the list from the previous step, meaning 1.jpg through 5.jpg will all be split according to the same width and height rules.
In practice, the width and height values should be determined by the intended use. For creating square thumbnail materials, enter the same width and height; for horizontal web cards, you can enter a width greater than the height; for vertical content slices, you can enter a height greater than the width. Since the screenshot shows no other complex parameters, it's suggested to focus on the two required fields for width and height, ensuring the entered values meet requirements.
Step 4: Set Save Location and Start Generating Thumbnails
After completing the fixed width and height settings, continue by clicking "Next". The progress bar at the top of the page shows subsequent steps are "Set Save Location" and "Start Processing". In the save location step, a clear output directory should be selected. For batch image splitting tasks, it's recommended to save the results in a new folder so the original images and split results don't mix.
Entering the start processing step executes the batch task. The software automatically generates thumbnail files based on the previously imported image list and the set width and height parameters. Upon completion, check the output directory, and you'll see a folder structure similar to the post-processing screenshot: each original image corresponds to a folder, containing sequentially numbered JPG thumbnails.
If there are many images, it's recommended to check three things after processing: first, if the number of folders matches the number of original images; second, if thumbnails were generated in each folder; third, randomly open a few thumbnails to confirm the image content and dimensions match expectations. After verification, these thumbnails can then be used for uploading, archiving, layout, or subsequent data processing.
Common Questions and Operation Suggestions
1. Which image formats is this method suitable for? The example in this article processes JPG files, and the extensions shown in the screenshots are also jpg. The software's image tools also display various image conversion functions, indicating it's aimed at image file processing scenarios. In actual use, priority should be given to the formats supported for import by the software; common JPG, JPEG, and PNG images can be tested first.
2. Will Fixed Width & Height Splitting change the original image? From the process perspective, the software will set a save location and output the split thumbnails. To ensure safety, it's recommended to select a new output directory and keep the original images. This way, even if the parameter settings are unsuitable, you can readjust the width and height and process again.
3. If I only want to cut a single image, can this be used? Yes. Although this function emphasizes batch processing, you can also add just one image to the list. The efficiency advantage of the batch tool is simply more obvious when there are many images.
4. How to choose between Average Splitting and Fixed Width & Height Splitting? If your goal is for each thumbnail to have a specific width and height, choose Fixed Width & Height Splitting; if your goal is to divide the image evenly into several parts, you can consider Average Splitting. The example in this article selects Fixed Width & Height Splitting and enters 200 and 200.
5. Why might the number of output thumbnails differ for each original image? Different original images have different dimensions. When cutting with the same width and height, the number of generated thumbnails may vary. In the post-processing screenshot, the 2nd folder has 28 thumbnails; the number for other folders may vary depending on the corresponding original image's size.
6. How to avoid messy result files? The most important thing is to set up the save location properly and use an independent output directory for each task. Before processing, you can also sort out the original image file names clearly, for example using regular names like 1.jpg, 2.jpg, making them easier to check and match after processing.
Summary: Batch Splitting by Fixed Width & Height for More Efficient Large Image Splitting
Batch splitting large images into multiple JPG thumbnails is a typical repetitive file processing task. Manual handling is not only time-consuming but also easily leads to inconsistent sizes and messy file management. Using HeSoft Doc Batch Tool , you can select "Split Image into Multiple Small Images" in the Image Tools, batch import original images, choose "Fixed Width & Height Splitting", enter the width and height for each thumbnail, then set the save location and start processing.
From the before-and-after effects, the original 5 large JPG images are organized into 5 corresponding folders, each containing sequentially numbered thumbnails. This batched, structured output method significantly improves the efficiency of image organization, material cutting, and file delivery. It is recommended to determine the target width and height based on actual use, such as 200×200, run a trial with a few images, confirm the results, and then batch process all images.
