Electronic invoices, electronic credentials, and layout files are often saved in OFD format, but many uploading, reimbursement, archiving, and communication scenarios require JPG images instead. This article focuses on the need to batch convert OFD pages into a single long image, introducing how to use HeSoft Doc Batch Tool to perform batch import, OFD to JPG conversion, page range selection, setting 300 PPI, and enabling multi-page stitching into a long image, helping office users quickly obtain clear, continuous, and easy-to-share image results.
E-invoices, electronic vouchers, electronic official documents, and business receipts are increasingly adopting the OFD format. The advantage of OFD is its stable layout, suitable for formal document preservation, but in actual office collaboration, many people prefer to get JPG images: mobile phones can view them directly, chat software can preview them directly, web backends can upload them directly, and reimbursement systems often require image formats. Thus, "how to batch convert OFD to JPG images" has become a high-frequency need.
Furthermore, if an OFD has multiple pages, exporting page by page will produce many images, which are neither easy to send nor easy to organize. Splicing multiple pages into one long image allows content to be displayed continuously from top to bottom, as convenient to read as a long screenshot. This article uses " HeSoft Doc Batch Tool " as an example to explain how to batch convert multiple OFD files to JPG and merge multiple pages into one very long image.
Applicable Scenarios: Why Convert E-Invoices, Vouchers, and OFD Fixed-layout Files to Long Images
In financial reimbursement scenarios, common e-invoice formats include OFD. If the reimbursement platform or approval process requires uploading images, converting OFD to JPG can reduce format compatibility issues. If the same receipt or voucher contains multiple pages of information, splicing into a long image allows reviewers to view continuously without switching between multiple images.
In file archiving scenarios, OFD files are suitable for preserving originals, but images are better for previews. Converting the first few pages or all pages of an OFD into a long image can serve as an index image, thumbnail preview, or quick reference material. For a large number of files, batch conversion is more reliable than manual screenshots.
In business communication scenarios, clients, suppliers, or colleagues may not have OFD reading tools installed. After exporting OFD to a JPG long image, the recipient can view it directly on a mobile phone or computer. Especially for pages like contract summaries, supporting documents, application forms, and receipts, a long image maintains reading coherence.
Therefore, the core value of batch converting OFD to JPG long images is not simple format conversion, but making files easier to open, send, and archive in office circulation. HeSoft Doc Batch Tool , as an office file batch processing software, can centrally execute repetitive conversion tasks for multiple files.
Effect Preview: Changes in File Form Before and After Conversion
Before conversion, the sample folder contains four OFD files: 1.ofd, 2.ofd, 3.ofd, 4.ofd. These are all source files to be processed. For users who frequently handle e-invoices or business materials, such numerically saved OFD files are very common.
After conversion, the files become JPG images: 1.jpg, 2.jpg, 3.jpg, 4.jpg. It can be seen that 1.jpg is displayed as a vertical long image, with multiple pages spliced into one image; the other JPGs are generated according to their respective OFD content. Such output results are suitable for direct preview, upload, or sending.
From a file management perspective, the converted file names maintain a corresponding relationship with the original files, which is very conducive to verification. For example, 1.ofd corresponds to 1.jpg, and 2.ofd corresponds to 2.jpg. For batch tasks, this correspondence can reduce the workload of subsequent renaming, searching, and manual confirmation.
Operation Steps: Batch Splicing OFD Pages into JPG Long Images
Step 1: Enter the OFD to JPG Image Function
Open HeSoft Doc Batch Tool , and find the "OFD to JPG Image" function in the main tool interface. In the screenshot, this function is located in the function card area, with the description text "Batch convert OFD files to JPG format images." This is the entry point for exporting OFD to images.
The operational purpose of this step is to ensure the subsequent processing target is JPG images, not PDF or other formats. Functions like "OFD to PDF" also exist in the interface; if the goal is a long image, "OFD to JPG Image" should be selected. After entering, the software will display a step-by-step wizard, making it convenient to complete the batch task according to the process.
Step 2: Add Files or Import OFD from Folder
After entering the function page, the first step is "Select records to process." In the upper-right area of the page, there are buttons like "Add File," "Import Files from Folder," "Clear," and "More." In the screenshot, four OFD files have already been imported, and their names, paths, extensions, creation times, and modification times are visible in the list.
If only a few files need processing, click "Add File" to select OFD; if a batch of e-invoices or vouchers is stored in one directory, using "Import Files from Folder" is more efficient. After importing, check that the extension is .ofd and confirm the summary record count at the bottom matches expectations. In the example, the record count is 4, indicating that four OFDs will be batch processed this time.
There is an operation column on the right side of the list, which can be used to remove records that do not need processing. If incorrect files are imported, you can click "Clear" to reselect. After confirming the file list is correct, click "Next" at the bottom to enter the processing parameter settings.
Step 3: Select Page Range According to Needs
On the "Set Processing Options" page, first set the "Processing Range." The screenshot shows the software provides options such as "All Pages," "First Few Pages," "Last Few Pages," "Odd Pages," "Even Pages," and "Custom." The example selects "First Few Pages" and fills in 2 for the range.
This setting means: Only the first 2 pages of each OFD will be converted. If your e-invoice or voucher has only 1 or 2 pages, this can quickly generate the required images; if your file contains more attachments but only the first page's information is needed, you can also control the output content this way.
If you want to keep all pages completely, choose "All Pages." If the signature page, conclusion page, or attachment page is at the end of the document, you can select "Last Few Pages." If there are special page number requirements, you can choose odd pages, even pages, or custom according to the options provided in the interface. The page range determines what content the long image includes; business requirements should be confirmed before setting.
Step 4: Set Image Pixel Density to Ensure Text and Seal Imprints are Clear
The "Image Pixel Density (PPI)" in the screenshot is 300. For documents like e-invoices, contracts, and vouchers, details such as text, amounts, QR codes, and invoice seals are important. If the PPI is too low, the image may look blurry, affecting review and recognition; if the PPI is too high, the image volume may increase, especially noticeable after splicing into a long image.
300 PPI is usually suitable for the imaging output of most office documents. You can first test the effect with a small number of OFDs, and after confirming that clarity, volume, and upload limits meet requirements, batch process all files. For formal reimbursement, archiving, or client delivery, it is recommended to prioritize ensuring clarity.
Step 5: Turn on the Switch for Splicing Multiple Pages into a Long Image
To turn multiple pages of an OFD into one long image, you need to enable the "Splice Multiple Pages into One Long Image" option. Located below the PPI setting in the screenshot, this option is the most critical one in this tutorial.
When enabled, the software will splice multiple pages from the same OFD that meet the page range criteria into one JPG image in order. For example, with the setting being the first 2 pages and splicing enabled, each OFD will output a long image containing the content of the first 2 pages. In the final processing result, 1.jpg appears as a long strip image, which is the effect brought by this setting.
If a long image is not needed, and you want each page as a separate image, this splicing option should not be enabled. However, for sending, previewing, archiving, and mobile reading, outputting one long image per OFD is generally more convenient for management.
Step 6: Continue to Set Save Location and Start Processing
After completing the processing options, click "Next." The process prompt at the top of the interface shows that "Set Save Location" and "Start Processing" follow. Although the screenshot does not expand these two pages, the wizard structure reasonably suggests that you need to specify the save directory for the converted JPG images first, then execute the batch processing.
It is recommended to keep the output directory separate from the original OFD directory, for example, by creating folders like "OFD to JPG Results" or "Long Image Output." This avoids mixing source and result files, making it easier to check if the conversion is complete. After starting the process, wait for the software to generate the JPG files; finally, the corresponding image results for the original OFDs can be viewed in the output directory.
Frequently Asked Questions and Notes
1. Can an e-invoice OFD still be used as the original after conversion to JPG?
JPG images are more suitable for viewing, uploading, and circulation, but they cannot replace the role of the original OFD in certain formal archiving scenarios. It is recommended to retain the original OFD file after conversion for future verification or re-export.
2. Why splice multiple pages into a long image?
Splitting multiple pages produces many images, making sending and organizing more troublesome. After splicing into a long image, one OFD corresponds to one JPG, making reading more continuous and closer to the user experience of a long mobile screenshot.
3. What if I only want to convert the first page?
You can select "First Few Pages" in the processing range and set the range to 1. The example screenshot fills in 2, indicating processing of the first 2 pages. You can adjust the number according to actual needs.
4. What if the output image is too large?
The volume of a long image is related to the number of pages, PPI, and page content. If the image is too large, you can reduce the page range, or adjust the PPI while ensuring clarity is acceptable. Before batch processing, it is recommended to test with a small number of files first.
5. How to avoid processing the wrong files after batch importing?
After importing, check the names, paths, and extensions in the table. In the example, the extension column is all .ofd, and the paths point to the same test directory. For formal processing, it is recommended to organize the source folder first to reduce the possibility of mixing in unrelated files.
