Electronic invoices, vouchers, and receipts are often saved in OFD format, but many reimbursement, archiving, or uploading scenarios require JPG images. This article explains how to use HeSoft Doc Batch Tool to convert multiple OFD files into JPG in one batch and, through the "stitch multiple pages into one long image" feature, output multi-page content as a continuous long image. The article covers applicable scenarios, before-and-after effects, detailed steps, and notes to help users efficiently complete the task of batch OFD-to-image conversion.
Electronic invoices, electronic documents, and various types of official receipts are increasingly adopting the OFD format. The advantage of OFD is its stable layout, making it suitable for preserving official documents. However, in daily office work, many people prefer JPG images: financial reimbursement systems may require image uploads, internal approvals favor direct previews, and sharing via mobile phones is more convenient with image formats. If an OFD file contains multiple pages, exporting each page as separate images can also cause management inconveniences.
The problem this article aims to solve is: how to batch convert multiple OFD files to JPG and combine the multiple pages of each OFD into a single, long image. This preserves the page order while reducing the number of attachments, making it highly suitable for processing electronic invoices, reimbursement vouchers, government documents, and archival materials into images.
The office software used in this tutorial is " HeSoft Doc Batch Tool ". As seen in the screenshots, it is a tool designed for batch document processing, offering various file conversion and office processing functions. The focus this time is using the "OFD to JPG Image" feature within "More Tools".
Applicable Scenarios: Why Electronic Invoices and OFD Documents Are Suitable for Conversion to JPG Long Images
First, it solves format compatibility issues. Not all computers and phones can directly open OFD files. After conversion to JPG, almost all devices can preview them, and the recipient does not need to install additional readers.
Second, it facilitates uploading to systems. Many reimbursement, review, archive, and business platforms support JPG image uploads but may not support OFD. Converting OFD to JPG reduces rejections caused by unsupported formats.
Third, it maintains continuous multi-page reading. If an electronic document or receipt has multiple pages, exporting them separately generates multiple images. After combining multiple pages into one long image, viewing only requires opening a single file and reading from top to bottom.
Fourth, it is suitable for batch processing. Finance, administration, and archive personnel often deal with batches of files rather than a single one. Using a batch tool allows for unified import, settings, and output, avoiding repetitive work.
Effect Preview: Changes in Files Before and After Conversion
Before processing, the folder contained multiple OFD files. As seen in the screenshot, the pending files include 1.ofd, 2.ofd, 3.ofd, and 4.ofd. These are the source files for this batch conversion.
After processing, corresponding JPG images appeared in the folder, such as 1.jpg, 2.jpg, 3.jpg, and 4.jpg. In the screenshot, 1.jpg appears as a tall, vertical image, which is the result of merging multiple pages into a long image. Other files will also be output as images based on their respective page content.
The advantage of this approach is the one-to-one correspondence between source and result files. Content that previously required opening an OFD file to view can now be browsed, sent, or uploaded directly as an image. For multi-page files, the long image reduces the number of pictures, making the materials tidier.
Operational Steps: Batch Converting Electronic Invoice OFD to JPG Long Images
Step 1: Open the Software and Select the OFD to JPG Function
After launching HeSoft Doc Batch Tool , select "More Tools" in the left function bar. The main area will display multiple conversion function cards. According to the screenshot, click "2. OFD to JPG Image" this time.
The description for this function is "Batch convert OFD files to JPG format images," which perfectly meets the need for converting electronic invoice OFD files to JPG. After selecting this function, the software enters a step-by-step process flow, allowing users to complete import, settings, and output sequentially.
Step 2: Import the OFD Files to be Processed
After entering the "OFD to JPG Image" page, the interface top provides operations like "Add Files," "Import Files from Folder," and "Clear." For batch conversion of electronic invoices or documents, it is generally recommended to first place the OFD files needing processing into the same folder, then use "Import Files from Folder." If only processing a few specific files, click "Add Files."
After importing, the files are displayed in the list. The screenshot shows 4 records: 1.ofd, 2.ofd, 3.ofd, and 4.ofd, located in the path D:\test\, with the extension .ofd. The bottom summary shows a record count of 4, indicating this batch task includes 4 files.
The purpose of this step is to add all OFD files requiring conversion to the same task queue. The expected result is a complete file list with correct paths and the .ofd extension. If unwanted files are mixed into the list, they can be removed using the delete button in the right-side operation column.
Step 3: Enter Processing Option Settings
After confirming the file list, click "Next" at the bottom. The software proceeds to the second step, "Set processing options." This determines which pages to convert, the output image clarity, and whether to merge into a long image.
In the screenshot, the "Processing Range" area offers multiple choices: All pages, The first few pages, The last few pages, Odd pages, Even pages, Custom. The current example selects "The first few pages," with the range number entered as 2.
If only the first two pages of your electronic invoice OFD need to be submitted, you can set it to the first 2 pages as in the screenshot; if you need to fully retain the entire OFD, select "All pages." If you only process odd pages, even pages, or specified pages, choose accordingly from the interface options. The page range must be clearly confirmed beforehand; otherwise, the final long image might miss pages or contain unnecessary content.
Step 4: Set Image Pixel Density (PPI)
Below the processing range, there is an "Image Pixel Density (PPI)" setting, shown as 300 in the screenshot. For electronic invoices, notes, and vouchers, clarity is crucial because the files may contain invoice codes, numbers, amounts, seals, QR codes, and other information.
300 PPI typically meets the needs of most office viewing and upload requirements. If set too low, the image is smaller but may affect text recognition; if set too high, the image is clearer but the file size increases. It is recommended to test the output effect with one or two files before batch processing to confirm that the platform can upload normally and the content is clear.
Step 5: Enable Page Stitching to Generate a Single Long Image
At the bottom of the processing options page, there is a switch for "Stitch multiple pages into one long image." To achieve converting multiple OFD pages into a single JPG long image, this option must be enabled.
After enabling, the software will stitch the pages within the processing range of a single OFD file in order into one image. For example, if an OFD file is set to process the first 2 pages, the output JPG will stitch these 2 pages vertically into one long image. This way, during reimbursement or archiving, one document corresponds to one image, making viewing more convenient.
If this switch is not enabled, the conversion result might be split into multiple images per page, failing to meet the "long image" goal. Therefore, check the status of this switch carefully before clicking Next.
Step 6: Set Save Directory and Start Batch Conversion
After completing the processing options, click "Next" to go to "Set save location." It is recommended to choose a dedicated folder for the output results, such as "Electronic Invoice JPG Long Images" or "OFD Conversion Results." This prevents mixing original OFD files with generated images and facilitates subsequent uploading and archiving.
After confirming the save location, enter the "Start processing" step. The software will process the OFD files one by one according to the import list, applying the unified page range, PPI, and long image stitching settings. Once processing is complete, open the save directory to see the generated JPG images.
From the post-processing screenshot, it's apparent that the conversion results correspond to the output based on file names. Users can first spot-check if 1.jpg contains the expected pages, then check other images. If the spot check results are correct, it indicates that the batch conversion settings meet the requirements.
Frequently Asked Questions and Important Notes
1. Can the original layout be maintained after converting Electronic Invoice OFD to JPG?
OFD itself is a layout file. After converting to JPG, it usually presents the page's visual effect as an image. To make text, seals, and QR codes clearer, it is recommended to set the PPI reasonably, such as the 300 shown in the screenshot.
2. Why am I only getting content from the first few pages?
Please check the "Processing Range." The screenshot example selects "The first few pages" and fills in 2, so it will only process the first 2 pages of each OFD. If you need all pages, please select "All pages."
3. Is a long image suitable for all OFD files?
Long images are suitable for scenarios requiring continuous reading and reducing the number of attachments. However, if an OFD file has a very large number of pages, the generated long image might be quite large, making it slower to open and upload. In this case, you can select partial pages based on business needs or evaluate if splitting the output is necessary.
4. How to reduce errors during batch processing?
It is recommended to first organize the source folder, only placing the OFD files that need conversion; check the list record count after import; confirm whether all pages are needed when setting the page range; finally, confirm the long image stitching switch is enabled. After the batch conversion is complete, spot-check several output JPGs.
5. Do the original OFD files still need to be retained?
It is recommended to keep them. JPG is suitable for submission, preview, and sharing, but the original OFD remains the formal source file. The conversion result can serve as a convenient copy, while the original files are used for long-term preservation and future review.
Summary
Batch converting Electronic Invoice OFD to JPG long images effectively solves problems such as format incompatibility, uploading inconvenience, and difficulties in viewing multiple pages. When using HeSoft Doc Batch Tool , the operational flow is clear: select "OFD to JPG Image," import multiple OFD files, set the page range and PPI, enable "Stitch multiple pages into one long image," and finally set the save location and start processing.
For office workers frequently dealing with invoices, vouchers, receipts, and archival materials, this batch processing method can significantly reduce repetitive operations and improve file organization efficiency. It is recommended that before formal batch conversion, you first test the effect with a small sample, confirm the clarity, page range, and long image results are error-free, and then process all OFD files at once.
