This article is intended for office users who need to convert a large number of PDFs into long screenshots, long images, or JPG previews, introducing the method of batch conversion using HeSoft Doc Batch Tool . Starting from user pain points, the article explains the file changes before and after processing, and in the order of screenshots, explains how to access the PDF tool, select converting PDF to JPG images, import multiple PDFs, set page ranges and PPI, enable multi-page stitching into a long image, and finally complete the output. Through this workflow, the repetitive labor of manual screenshotting and page-by-page exporting can be significantly reduced.
In office collaboration, there is often a need to process many PDF files, each containing multiple pages, and convert them into images. Ideally, each PDF would be turned into a single, very long JPG full-page screenshot. This makes it convenient for continuous viewing on a mobile phone, sharing with colleagues or clients, or uploading to a business system.
Traditionally, you would first open each PDF, take screenshots or export images page by page, and then manually stitch them together using an image tool. This is barely manageable for a few files but becomes highly inefficient with many. This article introduces how to use the office software " HeSoft Doc Batch Tool " to batch convert multiple PDFs into JPG long images, automating the repetitive format conversion work.
Use Cases: What Office Problems Does PDF to JPG Long Screenshot Solve
Converting PDFs to long JPG screenshots is commonly used for material display, mobile reading, online submission, and image archiving. For example, corporate promotional materials need to be uploaded to a web content system that only supports images; project reports need quick mobile preview without requiring the recipient to download a PDF; multi-page scans need to be a single continuous image for unified saving; training documents need to be converted to long images for course introductions or material previews.
The common thread for these needs is: a high number of files, repetitive operations, and high susceptibility to human error. Therefore, choosing office software that supports batch processing is more suitable for practical work than converting files one by one.
Result Preview: Batch Output of Multiple Long JPG Images from Multiple PDFs
The folder before processing contains four PDF files: 1.pdf, 2.pdf, 3.pdf, and 4.pdf. These are the input files for this batch conversion. Based on the file icons and extensions, the current materials are still in PDF format.
After processing is complete, corresponding JPG files appear in the folder: 1.jpg, 2.jpg, 3.jpg, and 4.jpg. Each JPG looks like a very tall vertical image, indicating that the multiple pages within the PDF have been stitched into a continuous long image. Such results are perfect for direct preview or distribution as image files.
Step 1: Open the PDF Tool and Find the JPG Conversion Feature
Open HeSoft Doc Batch Tool . In the left navigation bar, you can see categories like "Home", "Task Flow", "All Tools", "File Name", "Folder Name", "File Organization", "Word Tools", "Excel Tools", "PowerPoint Tools", and "PDF Tools". Since the processing target this time is PDFs, enter "PDF Tools".
In the PDF tools list, find "PDF to JPG Images". In the screenshot, this feature card is shown as the 18th item and comes with the description "Batch convert PDF files to JPG format images". This indicates it is suitable for processing multiple PDF files at once, not just single file conversion.
After selecting this feature, the software will enter a step-by-step processing page. The top of the page displays the task name "PDF to JPG Images" and provides a "Return to Main Panel" button, so you can easily go back to the feature list if needed.
Step 2: Add Multiple PDFs to the Processing List
In the first step of the task page, "Select records to process", you need to add the PDFs you want to convert to the list. The interface provides "Add File" and "Import Files from Folder" buttons at the top right. If files are scattered in different locations, use "Add File" to select them in batches; if files are concentrated in a single folder, using "Import Files from Folder" is more efficient.
The screenshot shows that four PDF files have been imported. The list displays the sequence number, name, path, extension, creation date, modification date, and actions. Example file paths are D:\test\1.pdf, D:\test\2.pdf, etc., with the extension pdf. The bottom summary shows a record count of 4.
The expected outcome of this step is that all PDFs to be converted to JPG long images appear in the list. Before proceeding, it is recommended to check the file names to confirm nothing is missing and no incorrect files were imported. After confirming, click "Next" at the bottom of the page.
Step 3: Select the PDF Page Range
After entering the second step, "Set Processing Options", you first need to set the processing range. The interface provides options like "All Pages", "First Few Pages", "Last Few Pages", "Odd Pages", "Even Pages", and "Custom". Different options suit different needs.
If you want to convert the entire PDF into a long image, select "All Pages". If you only want to create a preview long image, you can choose "First Few Pages". The screenshot shows "First Few Pages" is selected, and the range is filled with 5, meaning only the first 5 pages of each PDF will be processed. This makes the length of the generated long images more manageable and suitable for preview purposes.
If only certain pages in the document need to be output, you can choose odd pages, even pages, or a custom range based on the actual situation. Setting the page range reasonably can avoid generating unnecessary image content and reduce the output file size.
Step 4: Set PPI and Enable Long Image Stitching
Below the page range is "Image Pixel Density (PPI)". The value in the screenshot is 300. PPI affects the clarity of the output image, especially when the PDF contains a lot of text, tables, or thin line graphics; a suitable PPI makes the content easier to read. For regular office documents, 300 PPI is a reliable setting.
Next, pay attention to the switch for "Stitch multiple pages into one very long image". The screenshot emphasizes this option with a red border and arrow. It determines whether a long image is generated. When enabled, the software will stitch the selected pages in order into a single long image; if disabled, it does not meet the goal of "PDF to long screenshot".
After these settings, click "Next". Looking at the page flow, "Set Save Location" and "Start Processing" follow. It is recommended to select a new output folder during the save location stage to avoid mixing with the original PDFs. After starting the process, wait for the software to complete the batch conversion.
FAQ and Notes
1. Why choose JPG over other image formats?
JPG is a universal image format with high compatibility, suitable for viewing or uploading on computers, mobile phones, web backends, and most office systems. For PDF content primarily for reading and display, JPG is generally more convenient.
2. Does long image stitching alter the original PDF files?
The goal of this workflow is to generate new JPG image files. Judging from the results, the original PDFs remain, and the output files are saved in .jpg format. Thus, you can generate an image version while preserving the originals.
3. How many JPGs will be generated from multiple PDFs?
Based on the result image, 4 PDFs ultimately generated 4 JPGs, meaning each PDF produces one corresponding long image. This method makes it easy to find the output result based on the original file name.
4. How to prevent the long image from being too large?
This can be controlled in two ways: first, by reducing the number of pages processed, such as selecting only the first few pages; second, by setting an appropriate PPI based on clarity requirements. More pages and a higher PPI typically result in a larger output image.
5. Do I need to rename the PDFs before conversion?
Not necessarily. But if the file names are clear themselves, the output JPGs will also be easier to identify. In the example, 1.pdf and 2.pdf are converted to corresponding 1.jpg and 2.jpg, making the name relationship intuitive.
