When multiple OFD files need to be submitted to a system that only supports images, or need to be displayed continuously in chats, web pages, or mobile terminals, exporting OFD pages as JPG long images is more convenient. This article takes HeSoft Doc Batch Tool as an example to explain how to batch import OFD files, select the OFD to JPG image conversion function, set the processing range such as the first few pages or all pages, and enable the option to stitch multiple pages into a long image, helping users quickly complete batch conversion.
In many office scenarios, OFD files themselves are not the final delivery format. For example, reimbursement systems require uploading images, business personnel need to send electronic invoices to groups, archivists need to generate preview images for OFD files, or operations staff need to display fixed-layout document content on web pages. In such cases, if the recipient cannot open OFD directly, the simplest way is to convert the OFD files to JPG images.
The problem is that OFD files often come in batches rather than one or two; some OFD files also contain multiple pages. If you open them one by one, export page by page, and then manually merge them into a long image, it is not only inefficient but also prone to errors due to page order and file naming. The method introduced in this article uses the "OFD to JPG Image" function in the office software " HeSoft Doc Batch Tool " to batch convert OFD files to JPG and merge multiple pages into one very long image through an option.
Applicable Scenarios: What Problems Batch OFD to JPG Long Image Conversion Can Solve
Converting OFD to JPG long images is not simply changing the file extension; it renders fixed-layout pages into universal images and merges multi-page content into one image. This method is particularly suitable for office workflows requiring 'visibility, transferability, and ease of opening'.
For example, finance personnel receive multiple OFD electronic invoices and need to convert them to JPG before uploading to the reimbursement platform; administrative staff organize electronic supporting materials, hoping each OFD corresponds to one long image for easier file archiving; customer service or business personnel need to send key pages of contracts, receipts, or application forms to clients so they can view them without installing an OFD reader; archivists need to generate imaged previews for files for quick browsing. All these scenarios require a stable, batch-oriented, and repeatable conversion process.
The value of HeSoft Doc Batch Tool lies in reducing repetitive operations. It is not just a viewer for single files but software designed for batch processing of office files. For common data processing needs involving OFD, PDF, images, Word, Excel, etc., batch workflows can significantly reduce the number of manual clicks. This article focuses on its OFD to JPG long image function.
Effect Preview: From OFD Source Files to JPG Long Images
Before processing, the folder contains multiple OFD files. The screenshot shows four files: 1.ofd, 2.ofd, 3.ofd, and 4.ofd. These are all original fixed-layout files waiting to be processed; their file icons and extensions are displayed as OFD. If done manually, each file would need to be opened and exported individually.
After processing, the output files become JPG images, with names corresponding one-to-one to the original files, including 1.jpg, 2.jpg, 3.jpg, and 4.jpg. The screenshot shows that 1.jpg is clearly a vertical long image style, indicating that multiple pages have been placed into the same image; the other files generate corresponding JPG images based on their respective page content. Such results are convenient for unified viewing and verification against the original file names.
For batch conversion, the correspondence of output file names is crucial. Originally 1.ofd becomes 1.jpg after processing; originally 2.ofd becomes 2.jpg. This way, during subsequent uploading, organizing, compressing, or sending, there is no need to re-determine which OFD the image came from, reducing secondary organizing costs.
Operation Steps: Using HeSoft Doc Batch Tool to Generate OFD Long Images
Step 1: Find the "OFD to JPG Image" Entry Point
After opening the software, enter the main interface or the tool list area. The screenshot shows the software name in the upper left corner is " HeSoft Doc Batch Tool ", and the current version is v1.23.0. The page lists multiple conversion functions in card form, including "OFD to PDF", "OFD to JPG Image", "XPS to PDF", etc.
The task this time is to convert OFD pages to images and merge them into a long image, so you should select "2. OFD to JPG Image". The description text below the function card is "Batch convert OFD files to JPG format images," which matches the need of this article. Do not select "OFD to PDF", as that will export PDFs instead of JPG images.
After selecting this function, the software enters a step-by-step processing wizard. The advantage of the wizard is the clear workflow: select files first, then set processing options, then set the save location, and finally start processing. For batch tasks, this structure helps minimize omissions.
Step 2: Import the OFD Files to Be Converted
After entering the function page, there are two main import methods at the top: "Add Files" and "Import Files from Folder". If the files to be converted are scattered, you can select them one by one via "Add Files"; if the OFD files are all in the same directory, it is recommended to use "Import Files from Folder", which better suits batch processing habits.
The pending list in the screenshot has already imported 4 records, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd, with paths under D:\test\ corresponding to the file names, and the extension shown as ofd. The table also lists creation time and modification time, making it easy to confirm if these are the correct versions for this processing. The 'Summary' at the bottom shows a count of 4 records, indicating this batch task will process 4 OFD files.
The expected result of this step is that all OFDs to be converted appear in the list. If too many files are imported, you can remove unnecessary records from the operation column; if there is an import error, you can click "Clear" to re-select. After confirming everything is correct, click "Next" at the bottom.
Step 3: Select the Page Range for Conversion
After entering the "Set Processing Options" page, first set the processing range. The screenshot shows selectable ranges including "All Pages", "First Pages", "Last Pages", "Odd Pages", "Even Pages", and "Custom". In the example, "First 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 for conversion. If an OFD has 5 pages, only page 1 and page 2 will be processed; if another OFD has only 2 pages, both pages will be processed. This setting is very practical for business scenarios needing only a preview of the first and second pages.
If you want to preserve the complete content of each OFD, choose "All Pages". If you only care about the final signature pages or appendix pages, consider "Last Pages". If your documents have a fixed odd/even page structure, you can also choose Odd Pages or Even Pages as needed. The page range setting is the most critical content selection step before generating the long image; it is recommended to confirm it carefully based on delivery requirements.
Step 4: Set Image Pixel Density (PPI)
The page also provides a "Picture Pixel Density (PPI)" setting, with 300 used in the example. PPI affects image clarity, especially when OFD contains small font text, table lines, QR codes, red seals, or receipt information; clarity will directly impact identification and review.
Generally, a higher PPI helps retain more detail, but the output JPG file size will also increase. When batch processing dozens or hundreds of OFDs, file size becomes a factor to consider. The example uses 300 PPI, suitable for most office documents, electronic invoices, and voucher-type materials. If it's just for quick internal preview, you can adjust after understanding the effect; if for formal submission, prioritize ensuring clear readability.
Step 5: Enable Page Merging to Generate One Long Image
At the bottom of the "Set Processing Options" page, you can see a switch for "Merge multiple pages into one long image". This is the core setting for exporting OFD as a long image. When this option is enabled, the software will not split each page into separate images; instead, it will merge the pages within the specified range for the current OFD into one continuous long JPG image in sequence.
Taking the settings in the screenshot as an example, selecting "First Pages" with a range of 2 and enabling long image merging means each OFD will merge its first 2 pages into the same JPG. In the effect preview after processing, 1.jpg is in the long image format. Consequently, 4 OFD files ultimately correspond to 4 JPG images, rather than generating many more page images, making file management simpler.
After completing the page range, PPI, and long image merge settings, click "Next". Following the wizard flow on the interface, the next steps lead to "Set Save Location" and then "Start Processing". It is recommended to set the save location to a separate output directory to avoid mixing with the original OFD files. Finally, after starting the processing, wait for the software to batch generate the JPG results.
Common Questions and Precautions
Can text be edited after OFD is converted to JPG?
After conversion to JPG, the page content becomes an image and cannot be directly edited like document text. It is more suitable for previewing, uploading, sending, and archiving. If the source content needs modification later, the original OFD file should be retained.
Will a long image that is too long affect usability?
If an OFD has many pages and you select "All Pages" before merging into a long image, the image height may become very large. Some platforms might have restrictions on image dimensions or file size. If this occurs, you can export only the first few pages, process in batches, or adjust the range according to platform requirements.
Why is the output result one JPG per OFD file?
This is the expected result when "Merge multiple pages into one long image" is enabled. Multiple pages from the same OFD are combined into the same image, making the result closer to 'one file, one image'. If merging is not enabled, the output method might be more page-by-page image generation.
Any suggestions for importing files?
It is recommended to first place the OFD files to be converted into the same folder, and after importing, check the record count, file names, and extensions in the list. In the screenshot, the extension column uniformly displays ofd, indicating the imported objects meet this conversion's requirements.
What to do if the processed image is not clear enough?
Pay attention to the PPI setting. The example uses 300 PPI, suitable for most documents. If the output image still doesn't meet requirements, you can test a small number of files before adjusting the settings, and observe the balance between image clarity and file size.
Summary: Batch Export OFD Long Images for Smoother File Circulation
The key to exporting multiple OFDs as JPG long images is using office software that supports batch processing and enabling page merging in the conversion options. HeSoft Doc Batch Tool centralizes the work that originally required repeated opening, exporting, and merging through the wizard flow of "Select Files - Set Processing Options - Set Save Location - Start Processing".
If your work frequently involves OFD electronic invoices, electronic vouchers, fixed-layout documents, or multi-page materials that need conversion to images, it is recommended to follow the procedure in this article: first select "OFD to JPG Image", then batch import OFD files, set the page range and PPI, and finally enable "Merge multiple pages into one long image". This can significantly reduce repetitive labor and make file submission, sending, and archiving more efficient.
