Many OFD files contain multiple pages of content. Exporting page by page generates multiple images, which is inconvenient for sending, uploading, and continuous viewing. This article uses HeSoft Doc Batch Tool as an example to explain how to use the "Convert OFD to JPG Image" feature to batch convert multiple OFD files to JPG, and enable the "Merge multiple pages into one long image" option, so that each multi-page OFD is output as a single vertical long image, suitable for processing electronic invoices, vouchers, receipts, and archival materials.
In office document processing, the OFD format is often used for saving formal layout documents, but it also has obvious limitations in daily circulation: the recipient may not have an OFD reading environment, some business systems only allow image uploads, and viewing OFD on mobile phones is not as intuitive as JPG. Especially for multi-page OFD files, exporting page by page results in multiple images, which can easily lead to missed attachments when sending and may also be subject to quantity limits during upload.
A more efficient approach is to directly merge multiple OFD pages into a single long image. This way, one file corresponds to one JPG, allowing continuous top-to-bottom viewing while preserving page order and facilitating archiving. This tutorial will combine screenshots to explain how to batch convert OFD to JPG in the office software " HeSoft Doc Batch Tool ", focusing on setting up multi-page stitching into a long image.
The core value of this software is batch file processing, which reduces repetitive work. For users who need to process multiple OFD files at once, there is no need to repeatedly open each file, take screenshots, stitch, and save; you can simply complete the import and parameter settings in a single conversion task to uniformly generate image results.
Applicable Scenarios: Why Merge Multi-page OFD into a Single Long Image
Merging multiple OFD pages into a single long image is not simply about changing the format, but about making the file easier to use. The following scenarios are particularly common.
Organizing E-invoices and Reimbursement Vouchers: Financial staff often need to collect a large number of OFD electronic bills. If each bill has to be manually opened for inspection and then converted to an image, it takes up a lot of time. After batch conversion, the images can be directly used for preview, upload, or attachment archiving.
Submitting Government Documents and Electronic Receipts: Some government service platforms, business systems, or internal processes only support JPG image attachments. Converting OFD to images can reduce format compatibility issues. After merging multiple pages into a long image, the submitted materials are also more complete.
Previewing Contracts, Certificates, and Notices: When an OFD has multiple pages of content, scattered images can interrupt reading. A long image retains the top-to-bottom order of pages, suitable for quick viewing on web pages, mobile phones, and chat tools.
Batch Archiving and Unified Naming: As seen from the post-processing screenshots, source files 1.ofd, 2.ofd, 3.ofd, 4.ofd are converted to 1.jpg, 2.jpg, 3.jpg, 4.jpg. The file correspondence is clear, facilitating subsequent management.
Effect Preview: From OFD Files to Long JPG Images
Below is the state of the files before processing. The folder contains 4 OFD files, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd. At this point, they are still in OFD format, requiring a dedicated reader or an OFD-compatible environment to open and view.
After processing, the output files become JPG images. The image names maintain a correspondence with the original file names; for example, 1.ofd corresponds to 1.jpg, and 2.ofd corresponds to 2.jpg. In the effect image, you can see that 1.jpg appears as a vertical long image, indicating that multiple pages have been stitched into a single picture.
This result is very suitable for continuous reading. Users do not need to open multiple page images; they only need to open one JPG to view the content of the multiple converted pages within that OFD. For mobile communication, a long image is also easier to share than multiple scattered attachments.
Operating Steps: Using HeSoft Doc Batch Tool to Convert OFD to Long Image
Step 1: Select OFD to JPG in the Tool List
After opening the software, the product name displayed in the top left corner is " HeSoft Doc Batch Tool ". Judging from the interface layout, it is a batch document processing software designed for office scenarios. The left side contains function categories; in the current screenshot, "More Tools" is selected.
In the main area, find "2. Convert OFD to JPG Image". The description for this function reads "Batch convert OFD files to JPG format images". Click this function card to enter the OFD to image task page.
The key to this step is choosing the right function. If you select "Convert OFD to PDF", you will get a PDF; however, this tutorial requires JPG images, and the long image stitching needs to be enabled later, so you should enter "Convert OFD to JPG Image".
Step 2: Batch Import OFD Files
After entering the task page, you can see "Add Files" and "Import files from Folder" at the top. If the number of files is small, you can click "Add Files" to select specific OFDs; if all files to be converted are in the same folder, it is recommended to use "Import files from Folder", which is more in line with the idea of batch processing.
After importing, the software will display file information in a list, including serial number, name, path, extension, creation time, modification time, etc. In the screenshot, 4 records have been imported, all with the ofd extension, and the summary record count at the bottom is 4.
The expected result of this step is that all files to be processed appear in the list. It is advisable to check the names and paths before proceeding to the next step to avoid adding files that do not need conversion. If a record should not be processed, you can remove it by clicking the delete icon on the right side of that row.
Step 3: Click Next, Set Processing Range
After confirming the file list is correct, click "Next" at the bottom to enter the second step, "Set Processing Options". On this page, you first need to set the processing range. The options shown in the screenshot include "All Pages", "First few Pages", "Last few Pages", "Odd Pages", "Even Pages", and "Custom".
The current screenshot shows "First few Pages" selected, with a range value of 2 entered. This means that only the first 2 pages of each OFD file will be converted. If your goal is to merge a complete OFD into a single long image, you should select "All Pages"; if you only need a summary of the first few pages, you can keep a setting similar to the screenshot.
The page range directly determines which content the long image includes. For example, if an OFD has 5 pages, and "First few Pages" is selected with a value of 2, the final stitched long image will only contain the first 2 pages, not all 5. Therefore, before batch processing, you must clarify the business requirement: a full conversion, or only exporting some pages.
Step 4: Set Image Pixel Density, Control Clarity
Below the processing range, you can see the "Image Pixel Density (PPI)" input box. The value in the screenshot is 300. PPI can be understood as the fineness of the output image; it affects the detail performance of text edges, seals, QR codes, table lines, etc.
For most office materials, 300 PPI is a relatively safe choice, guaranteeing reading clarity without making the image file size excessively large. If the file contains much small text, red seals, or QR codes, setting it too low is not recommended, as it may affect recognition and viewing. If it's only for a temporary preview, you can adjust it based on actual needs.
Step 5: Enable Multi-page Stitching into a Long Image
Continue viewing the processing options page; below, there is a setting "Stitch multiple pages into one very long picture". This switch is key to achieving multi-page OFD merging into a long image. When enabled, the selected multiple pages within the same OFD will be stitched sequentially into a single vertical JPG image.
If you want each page to be output as a separate image, you do not need to enable this switch; but if the goal is "one long image output per OFD file", you need to enable it. In the screenshot, this option is highlighted with a red box, indicating it is an important setting for this conversion.
After enabling long image stitching, the number of output files is usually easier to manage: one source OFD corresponds to one JPG result. For batch archiving, this correspondence is very clear and makes subsequent searching more convenient.
Step 6: Set Save Location and Execute Conversion
After confirming the processing options, click "Next" to enter "Set Save Location". It is recommended to specify a separate output directory for the conversion results to avoid mixing them with the original OFDs. For example, you could create an "OFD to JPG Long Image Results" folder to centrally store the generated JPGs.
After setting the save location, proceed to "Start Processing". The software will convert the files in the list one by one, applying the same set of page range, PPI, and long image stitching settings. Once processing is complete, open the output folder to view the generated JPG images.
If the output results look similar to the effect preview, it means the batch OFD to JPG conversion is complete; if some files did not meet expectations, you can go back to the processing range or long image switch settings to check the parameters.
Frequently Asked Questions and Notes
1. Will multiple OFDs be merged into one overall long image?
Based on the screenshots and functional logic, this feature batch converts OFD files to JPG images. After enabling "Stitch multiple pages into one very long picture", it usually merges multiple pages within the same OFD file into a single image, rather than merging all OFD files into one master image. The post-processing screenshots also show 1.jpg, 2.jpg, 3.jpg, 4.jpg, indicating results are still output separately per source file.
2. How do the output filenames correspond to the original files?
In the effect image, you can see that 1.ofd corresponds to 1.jpg after conversion, and 2.ofd corresponds to 2.jpg. This naming method facilitates verification. However, in actual use, it is still recommended to spot-check a few files after output to confirm the content and filename correspondence is correct.
3. What if the long image is too large?
The size of the long image is related to the number of pages, PPI settings, and complexity of the page content. If the generated image is too large, you can consider reducing the processing page range or appropriately lowering the PPI. However, for official vouchers and materials requiring text recognition, excessively reducing clarity is not recommended.
4. Should I back up the original OFDs before batch processing?
It is recommended to keep the original OFD files. JPG is suitable for preview, upload, and sharing, but OFD as the source file is better for long-term preservation. During batch conversion, it is best to separate the output directory from the source file directory to avoid accidental deletion or confusion.
Summary
Merging multiple OFD pages into a single JPG long image can significantly improve the convenience of file viewing, sharing, and uploading. When using HeSoft Doc Batch Tool , you only need to enter "Convert OFD to JPG Image", batch import OFD files, set the processing range and PPI, and then enable "Stitch multiple pages into one very long picture" to complete the batch conversion.
For users who frequently process e-invoices, vouchers, government receipts, and archival materials, this batch method is more stable and time-saving than manual screenshotting and stitching. It is recommended to test the page range and clarity with a small number of files before formal processing, confirming the results meet requirements before executing batch conversion on a large number of OFD files.
