This article explains how to use HeSoft Doc Batch Tool to batch convert multiple OFD files to JPG images, and stitch multiple pages from the same OFD into one long image. Suitable for scenarios such as electronic invoices, electronic vouchers, contracts, reports, and archived files, avoiding the need to manually open OFD files one by one, take screenshots of each page, or manually stitch images. The article combines screenshots of the software interface to illustrate the complete process, from selecting the function, adding OFD files, setting page ranges, setting PPI, to enabling "Stitch multiple pages into one long image."
In daily office work, OFD files frequently appear in scenarios such as electronic invoices, electronic vouchers, electronic official documents, contract archiving, and financial reimbursement materials. Compared to ordinary images, OFD is more suitable for fixed layouts and electronic archiving, but many platforms do not directly support the OFD format when forwarding, previewing, uploading to systems, or inserting into documents. Especially when an OFD file has multiple pages, taking screenshots page by page, exporting them one by one, and then manually stitching them into a long image using a picture tool is time-consuming and prone to problems like incorrect page order, inconsistent clarity, and misaligned edges.
The problem this article aims to solve is: how to batch convert OFD files to JPG images and stitch the multiple pages from the same OFD file into a single long picture. Using the office software " HeSoft Doc Batch Tool " shown in the screenshots, you can add multiple .ofd files at once, uniformly set the conversion range and image pixel density, and enable the "Stitch multiple pages into a very long picture" option, thereby reducing repetitive operations and improving the efficiency of batch file processing.
Applicable Scenarios: When is it suitable to convert OFD pages into a long image
Batch converting OFD pages to a long JPG image is suitable for the following types of office needs:
- Electronic Invoice Organization: Some electronic invoices or receipts are saved in OFD format. Converting them to JPG makes it more convenient to preview and upload them in WeChat, emails, reimbursement systems, and OA systems.
- Merged Preview of Multi-page Vouchers: If an OFD file contains multi-page vouchers, stitching the pages into a long image eliminates the need to flip back and forth when viewing, making it suitable for quick verification.
- Converting Contracts and Supporting Documents to Images: Some business systems only allow uploading image formats like jpg, jpeg, or png. In these cases, you can first convert the OFD to JPG.
- Alternative to Manual Screenshots for Archives: There's no need to open OFD files for screenshots page by page, nor manually stitch them together using image editing software.
- Batch File Processing: When a folder contains multiple files like 1.ofd, 2.ofd, 3.ofd, 4.ofd, using a batch processing tool can complete the conversion in one go, avoiding repeated clicks.
Please note that this article focuses on "stitching multiple pages of an OFD into a very long JPG image." If your goal is just to export each page as a separate image, you can also use the same function, but you need to adjust the page range and stitching options according to your actual needs.
Effect Preview: Before processing, multiple OFD files; after processing, long JPG images
Before Processing: Multiple OFD files to be converted
From the pre-processing screenshot, you can see that there are 4 OFD files in the folder, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd. If these files were opened and exported as images one by one, the operational steps would be repeated many times; if some of these OFDs also contain multi-page content, the manual processing cost would be even higher.
For roles like finance, administration, legal, and archive management, processing dozens or even hundreds of OFD files at a time is not uncommon. The value of the office software's batch processing lies in delegating the "repetitive file conversion actions" to the tool for unified execution, with the user only needing to set up the rules before starting.
After Processing: Each OFD is output as a corresponding JPG image, and multiple pages can be stitched into a long image
From the post-processing screenshot, you can see the original OFD files have been converted into JPG images, such as 1.jpg, 2.jpg, 3.jpg, and 4.jpg. Among them, 1.jpg is displayed as a relatively long vertical image, indicating that multi-page content can be stitched into one long picture for continuous viewing.
This output method is very suitable for scenarios requiring a "one-time preview of the entire material." For example, if an OFD file contains two pages of invoice details or two pages of vouchers, synthesizing them into a long picture makes it more intuitive to forward to colleagues or upload to a system, and reduces the risk of missing a page during upload.
Operation Steps: Batch converting OFD file pages into a long image
Step 1: Select the "OFD to JPG Image" function in the software
After opening " HeSoft Doc Batch Tool ", you can find the conversion functions under "More Tools" on the software's homepage or tool list. The screenshot currently highlights "2. OFD to JPG Image", indicating this function is for batch converting OFD files to JPG format images.
The goal of this step is to enter the correct processing module. Since there are many office file formats, such as PDF, CAD, XPS, Word, Excel, and PowerPoint, the corresponding conversion functions differ for each format. When processing OFD files, you should select the clearly labeled "OFD to JPG Image" and avoid mistakenly selecting "OFD to PDF" or other format conversion functions.
After entering this function, the software will lead you to a step-by-step processing interface, typically including flows for selecting records to process, setting processing options, choosing a save location, and starting the process. This flow design is suitable for batch office tasks, as users can first confirm the file list, then uniformly set parameters, and finally execute them all at once.
Step 2: Add the OFD files to convert and confirm the list
After entering the "OFD to JPG Image" function, you can see buttons like "Add Files," "Import Files from Folder," "Clear," and "More" at the top right of the page. For a small number of files, you can click "Add Files" to select them one by one; if all the OFD files are in a single folder, you can use "Import Files from Folder" for batch importing.
The screenshot shows 4 imported records, with file names 1.ofd, 2.ofd, 3.ofd, and 4.ofd, located in the D:\test\ directory. The table also displays information like extension, creation time, and modification time, making it convenient to verify the files before batch processing.
It is recommended to focus on checking the following in this step:
- Is the file quantity correct: The bottom of the screenshot shows "Record Count: 4," indicating that 4 OFD files will be processed.
- Is the file extension .ofd: The extension column in the table shows .ofd, meaning the file format matches.
- Is the path correct: If same-name files are scattered in different directories, it's advisable to confirm the path to avoid processing the wrong files.
- Is there a need to delete any records: There is a delete icon to the right of each record. If a file doesn't need conversion, it can be removed before processing.
After confirming the file list is correct, click the "Next" button at the bottom of the interface to enter the processing options settings. This step is critical for batch processing, as the subsequent settings will apply to all OFD files in the current list.
Step 3: Set the page range to convert
In the "Set Processing Options" interface, you can see the settings related to "Processing Range." The selectable options in the screenshot include "All Pages," "First Few Pages," "Last Few Pages," "Odd Pages," "Even Pages," and "Custom." The current example selects "First Few Pages" and enters "2" in the "Range" input box.
This means the software will process the first 2 pages of each OFD file. For files like electronic invoices, vouchers, and supporting documents, if you only need the first page or first few pages, you can use "First Few Pages" to control the output range; if you need to completely convert the entire OFD, you can select "All Pages."
Typical uses for different page ranges are as follows:
- All Pages: Suitable for complete archiving, full conversion to images, or scenarios requiring all content to be preserved.
- First Few Pages: Suitable for scenarios where you only focus on the first page, cover, invoice header, or first few pages of a voucher.
- Last Few Pages: Suitable for when you only need the last page of an attachment, signature page, conclusion page, etc.
- Odd Pages or Even Pages: Suitable for special scenarios requiring split processing by odd/even pages.
- Custom: Suitable for converting only a specified page range.
The core of the example in this article is to generate a long image, so if you want multiple pages from an OFD to appear in the same JPG, you need to select a processing range that includes multiple pages. For instance, select "All Pages," or as in the screenshot, select "First Few Pages" and enter a page number greater than 1.
Step 4: Set the image pixel density PPI to control clarity
In the same settings interface, you can see the "Image Pixel Density (PPI)" option, where the screenshot has entered 300. PPI can be understood as the pixel density of the output image. A higher value generally means a clearer image, but the resulting JPG file size may also be larger.
For common office scenarios, 300 PPI is a practical choice: it ensures that text, tables, QR codes, seals, and other content are clear and readable, without excessively bloating the file size. If it's only for simple preview, you can lower it according to actual needs; if it's for printing, archiving, or uploading to a review system, it is recommended to maintain high clarity.
You can refer to the following principles when setting PPI:
- For screen preview: Choose a moderate PPI to reduce image file size.
- For reimbursement, review, or archiving: It is recommended to use a high PPI to ensure QR codes, red stamps, and small text are clear.
- When there are many files: Balance clarity and output file size to avoid generating excessively large image files.
Step 5: Enable "Stitch multiple pages into a very long picture"
This is the key setting for achieving the goal of this article. The screenshot below shows the option "Stitch multiple pages into a very long picture," presented with a toggle switch. Once enabled, the selected multiple pages within the same OFD file will be stitched into one long image, rather than being scattered across multiple images.
For example, if 1.ofd has 2 pages, the processing range is set to "First Few Pages: 2," and long image stitching is enabled, the processed result will be closer to 1.jpg in the screenshot: two pages of content connected vertically, forming a long single JPG image. This way, you only need to open one image to see multiple pages continuously.
This function is especially suitable for the following needs:
- Merging multi-page OFD invoices or vouchers into one image for convenient one-time uploading.
- Stitching multi-page instructions, receipts, or supporting documents into a long picture for easy sending in chat tools.
- Converting multi-page layout files into a continuous image, reducing the need for repeated page flipping during viewing.
- Avoiding manual stitching using image editing tools, thus reducing the probability of errors.
After confirming the page range, PPI, and long image stitching option, click "Next." Following the interface flow, you will then proceed to the save location settings and the start processing step. After setting the output directory, start the processing, and the software will batch convert the OFD files in the list according to the current rules.
Frequently Asked Questions and Notes
1. Why choose JPG format instead of keeping OFD?
OFD is suitable for electronic document archiving, but in many office collaboration scenarios, JPG images are more universal. For example, mobile preview, web upload, email attachments, instant messaging, inserting into Word or WPS documents — JPG usually has better compatibility. After converting OFD to a long JPG image, the recipient doesn't necessarily need a dedicated OFD reader.
2. Will the file be very large after stitching into a long image?
If there are many pages and the PPI setting is high, the long image file size might increase. This is normal, as the long image contains the image information of multiple pages. It is recommended to set the page range according to the actual purpose (e.g., do not select all pages if only the first 2 are needed); if it's just for preview, you can also lower the PPI appropriately.
3. Does each OFD generate one long image?
After enabling "Stitch multiple pages into a very long picture," the stitching is typically performed on the selected multiple pages within each individual OFD file. That is, 1.ofd will output a corresponding 1.jpg, and 2.ofd will output a corresponding 2.jpg. It does not merge multiple different OFD files into the same picture, but rather stitches the multiple pages from a single OFD file into one long image.
4. How should I choose the page range?
If you need to keep all pages of each OFD intact, choosing "All Pages" is more appropriate. If you only need the first few pages, such as the first page of an invoice or the first page and detail page of a voucher, you can select "First Few Pages" and enter the number. The example in the screenshot fills in "2," indicating processing the first two pages of each file.
5. Do I need to back up the original files before batch conversion?
From the screenshot flow, the software converts the OFD output to JPG images, and the original OFD file remains as the input file. For safety, when processing a large number of important files, it is still recommended to keep the original OFD files and save the output images to a separate folder for verification and management.
Summary: Using a batch processing tool to convert multi-page OFDs into long images is more efficient
Batch converting OFD file pages into a single long image essentially solves the problems of "format incompatibility, inconvenience in viewing multiple pages, and low efficiency in manual stitching." Through the "OFD to JPG Image" function in HeSoft Doc Batch Tool , you can first batch import multiple .ofd files, then uniformly set the page range, image pixel density PPI, and enable "Stitch multiple pages into a very long picture."
Compared to opening OFDs individually, taking screenshots page by page, and manually compositing a long image, this approach is more suitable for batch file processing in daily office work. Whether for electronic invoices, reimbursement vouchers, contract materials, or archived files, as long as you need to convert OFD to a long JPG image, you can follow the steps in this article. It is recommended that before formally processing a large number of files, you test the page range and PPI with a small number of OFDs, and only after confirming the output meets your requirements, execute all tasks in bulk.
