This article explains how to use HeSoft Doc Batch Tool to batch convert multiple OFD files into JPG images, and use the "stitch multiple pages into a long image" option to combine specified pages from each OFD into a single long image. The tutorial covers the complete workflow, including adding files, setting page ranges, adjusting image pixel density, enabling long image stitching, setting the save location, and starting the process. It is suitable for batch conversion scenarios involving electronic invoices, electronic vouchers, notification files, archived materials, and more.
In daily office work, OFD files frequently appear in scenarios such as electronic invoices, electronic vouchers, financial receipts, government documents, contract attachments, and notification materials. Often, the file itself contains multiple pages, but when uploading to a system, sending to a client, incorporating into a report, or archiving materials, we prefer to have a single complete JPG image. Manually opening each OFD, taking screenshots, saving, and then splicing them together is not only time-consuming but also prone to problems like disordered page sequence, inconsistent clarity, and chaotic file naming.
This article aims to solve: how to batch convert the pages of OFD files into one long image. The tool used here is the office software " HeSoft Doc Batch Tool " shown in the screenshots. Its positioning is a batch processing tool for office documents, suitable for handling a large number of repetitive file conversion tasks. By using the "Batch convert OFD files to JPG format images" feature and enabling the "Merge multiple pages into one long image" option, each OFD file can be output as a single JPG long image in page order, significantly reducing repetitive operations.
Applicable Scenarios: When is it suitable to composite OFD pages into a JPG long image?
Converting OFD to a JPG long image is not a simple format conversion; it is more suitable for office scenarios requiring "continuous reading, quick preview, and unified uploading." For example, if an OFD electronic invoice or voucher contains multiple pages, and the system only allows image uploads, or the recipient cannot conveniently install an OFD reader, converting to JPG makes viewing and circulation easier.
Common applicable scenarios include:
- Electronic invoice archiving: Composites multi-page OFD invoices, details, or receipts into a single JPG long image for easy previewing in folders.
- Reimbursement material organization: Batch converts multiple OFD vouchers into images for unified submission to financial systems or approval platforms.
- Retention of government and tax documents: Some platforms download documents in OFD format. If they need to be displayed in Word, PPT, emails, or web pages later, the image format is more universal.
- Batch material preview: When a batch of OFD files needs quick content verification, a JPG long image is more intuitive than opening each OFD individually.
- Mobile sharing: Viewing a JPG long image directly on a phone is usually more convenient than opening an OFD file.
If there are only a few files, manual conversion might be acceptable; but when the number of files reaches dozens or hundreds, the value of a batch processing tool becomes very obvious. It allows users to import multiple files at once, set conversion parameters uniformly, and then output the results centrally.
Effect Preview: Multiple OFD files before processing, JPG images after processing
First, look at the file status before processing. From the screenshot, you can see multiple OFD files in the folder, such as 1.ofd, 2.ofd, 3.ofd, and 4.ofd. Opening and converting these files one by one would generate a lot of repetitive actions.
After processing is complete, the output results become JPG image files, e.g., 1.jpg, 2.jpg, 3.jpg, 4.jpg. Note that when "Merge multiple pages into one long image" is enabled, a multi-page OFD file will be composited into a single vertical long image according to the selected page range. In the effect image, you can see that 1.jpg is displayed as a vertically long image, indicating it has merged content from multiple pages into a single picture for convenient continuous viewing.
The advantage of this output method is very direct: each OFD corresponds to one JPG, resulting in fewer files, more continuous viewing, and more convenient uploading or sharing. The long image method is particularly suitable for materials like batch electronic receipts, instruction documents, and notification attachments.
Operation Steps: Batch converting OFD file pages to one long image
Following the sequence of screenshots, here is how to complete the OFD to JPG long image operation in HeSoft Doc Batch Tool . The entire process can be understood in four stages: selecting the function, importing files, setting processing options, and setting the save location to start processing.
Step 1: Enter "More Tools", select "Convert OFD to JPG image"
After opening the software, in the left tool category, you can see entries like "Homepage, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, More Tools". The screenshot shows the current page is "More Tools".
In the function card area, find "2. Convert OFD to JPG Image". The card description is "Batch convert OFD files to JPG format images". This is the feature used in this article. After clicking this function, it enters the batch conversion interface.
The purpose of this step is to tell the software the type of task to perform: not OFD to PDF, nor other CAD or XPS conversions, but converting OFD files into JPG images. Only after selecting the correct function will parameters like page range, pixel density, and long image compositing appear.
Step 2: Add the OFD files to process
After entering the "Convert OFD to JPG Image" function, you can see buttons like "Add Files", "Import Files from Folder", "Clear", and "More" at the top of the interface. The middle area is the list of files to be processed, with list fields including number, name, path, extension, creation time, modification time, and action.
If the number of OFD files is small, you can click "Add Files" to manually select the files to convert. If the files are already gathered in the same folder, you can use "Import Files from Folder" to import all OFD files in that directory at once. The screenshot shows 4 records have been imported, namely 1.ofd, 2.ofd, 3.ofd, 4.ofd, with the path shown under the D:\test\ directory and the extension all being ofd.
After importing, it is recommended to check the file list: confirm the file quantity is correct and that there are no files that shouldn't be processed. If a file was imported by mistake, you can use the delete button in the corresponding row's "Action" column to remove it. After confirming correctness, click "Next" at the bottom to enter the processing options settings.
The expected result of this step: all OFD files that need conversion appear in the list, and the record count matches the actual number of files to process. This is the key to batch conversion; subsequent settings will be applied to these files simultaneously, avoiding repetitive configuration one by one.
Step 3: Set the processing range, choose which pages to convert
After entering the second step "Set processing options", first set the "Processing Range". Visible options in the interface include "All Pages", "First Few Pages", "Last Few Pages", "Odd Pages", "Even Pages", "Custom". These options determine which pages the software takes from each OFD file to convert into images.
In the screenshot, "First Few Pages" is selected, and the number 2 is entered in the "Range" input box. This means the software will take the first 2 pages from each OFD file for conversion. If your requirement is to composite the entire OFD into one long image, you can select "All Pages"; if you only need the first few, last few, or specific pages, you can choose the corresponding range based on the actual situation.
This step is very important. Because a long image does not necessarily mean converting all pages; it will perform compositing based on the page range you set. For example, if you select "First Few Pages" and enter 2, each OFD will ultimately composite its first 2 pages into one JPG long image; if you select "All Pages", all pages will be composited into an even longer image.
Step 4: Set the image pixel density PPI to control output clarity
On the same settings page, you can see the "Image Pixel Density (PPI)" input field. The screenshot shows a value of 300. PPI can be understood as a parameter related to the output clarity of the image. Generally, a higher value means finer image details but possibly a larger generated file size; a lower value might result in a smaller file size but potentially lower clarity when zooming in for viewing.
For materials requiring retention of text details, such as invoices, vouchers, contracts, and explanatory documents, 300 PPI is a fairly common setting. It balances clarity and file size. If only used for quick previewing, it can be reduced according to actual needs; if used for printing or high-precision archiving, it can be adjusted based on the software's allowed range and file size requirements.
The purpose of this step's operation is to ensure the output JPG long image has appropriate clarity. Especially since OFD files often contain details like QR codes, seals, table lines, amounts, and tax numbers, a PPI setting that is too low may affect recognition and reading.
Step 5: Enable "Merge multiple pages into one long image"
The core setting of this article is right here. Below "Image Pixel Density (PPI)" in the screenshot, you can see the option "Merge multiple pages into one long image", and this area is highlighted with emphasis. After toggling this switch on, the software will composite multiple pages within the processing range from the same OFD file into a single vertical long image in order.
If this option is not enabled, multi-page content might typically be output as multiple images; after enabling it, each OFD is more suitable for forming a continuous JPG file. This option is very practical for scenarios where you need to browse the entire material at once or a platform only expects a single image upload.
Note that the long image compositing range is still controlled by the "Processing Range" mentioned earlier. For example, in the screenshot, "First Few Pages" is selected with a range of 2, and long image compositing is also enabled, so each OFD will merge its first 2 pages into one JPG long image. If you want the entire document to be composited, you should select "All Pages" in the processing range.
Step 6: Proceed to the next step, set the save location, and start processing
After setting the page range, PPI, and long image compositing toggle, click "Next" at the bottom. From the process flow at the top of the interface, you can see there are two subsequent stages: "Set Save Location" and "Start Processing". Although the screenshot doesn't show the specific details of the save location page, it can be reasonably inferred from the process names: the user needs to choose the output directory for the converted JPG images, then proceed to the start processing step.
It is recommended to set the output directory to a separate folder, such as "Conversion Results" or "JPG Long Image Output", to prevent the generated images from mixing with the original OFD files. This facilitates subsequent verification of file counts, checking conversion effects, batch uploading, or backups.
After completing the save location settings, enter "Start Processing". The software will batch convert OFD files to JPG images in the order of the file list. Once processing is complete, you can see the result files like 1.jpg, 2.jpg, 3.jpg, 4.jpg in the output folder.
Frequently Asked Questions and Notes
1. Why is the output JPG, not PNG or PDF?
The function name used this time is "Convert OFD to JPG Image", and the description in the screenshot is also "Batch convert OFD files to JPG format images", so the output format is JPG. JPG has good universality and is suitable for email sending, system uploads, web display, and general office viewing.
2. Will the long image composite all pages?
Not necessarily. Long image compositing follows the "Processing Range" execution. If "All Pages" is selected, all pages of the entire OFD will be composited into one long image; if "First Few Pages" is selected and 2 is entered, only the first 2 pages will be composited. You need to confirm your page range requirements before operation.
3. What is a suitable PPI setting?
The screenshot sets it to 300 PPI. For invoices, vouchers, contracts, and spreadsheet-type files, 300 usually provides a good reading effect. If there are many files and strict requirements for image volume, it can be reduced appropriately; if higher clarity is needed, it can be adjusted according to the actual situation.
4. Do I need to check the file list after batch importing?
It is recommended to check. Especially when importing from a folder, files that don't need processing might be imported. You can confirm accuracy by checking file names, paths, extensions, and record counts to avoid over-processing or omissions.
5. How will the output file names correspond to the original files?
From the post-processing effect image, we can see that 1.ofd, 2.ofd, 3.ofd, 4.ofd generate corresponding 1.jpg, 2.jpg, 3.jpg, 4.jpg. In actual use, it is recommended to keep the original file naming clear, so the converted JPGs can more easily correspond to the source files.
Summary: Quickly compositing multi-page OFD content into a JPG long image using a batch processing tool
Converting OFD file pages into one long image has core steps that are not complicated: enter "More Tools", select "Convert OFD to JPG Image"; import the OFD files to process; set the page range; set the image pixel density PPI; enable "Merge multiple pages into one long image"; and finally set the save location and start processing.
