This article explains how to batch convert selected pages from multiple OFD files into JPG images, suitable for office scenarios where you only need to export the first page, the first few pages, the last page, odd/even pages, or a custom page range. Using HeSoft Doc Batch Tool , you can import multiple OFD files at once, uniformly set the processing range, image pixel density, and save location. This reduces repetitive tasks like opening files individually, taking screenshots manually, or exporting page by page, thereby improving efficiency in file organization, receipt archiving, and material submission.
In daily office work, OFD files are frequently used for scenarios such as electronic invoices, official electronic documents, vouchers, contracts, and archival materials. Often, we don't need to convert an entire OFD document into images, but rather only need to export a portion of its pages: for example, extracting only the first 2 pages of each OFD file as preview images, exporting only the last few pages as signature pages, or only converting odd or even pages for subsequent verification. If there are only one or two files, manually opening, taking screenshots, and saving as images can be barely manageable; but when the number of files grows to dozens or hundreds, repetitive operations become very time-consuming and prone to issues like missed conversions, incorrect conversions, and naming confusion.
This article uses the "OFD to JPG Image" function in HeSoft Doc Batch Tool as an example to demonstrate how to batch convert specific pages of OFD files to JPG format images. You can follow the steps in the screenshot order: first select the function, then import multiple OFD files, then set the page processing range and image pixel density, and finally save the output results. The focus of the entire process lies in "batch" and "specific pages": you neither need to process files one by one, nor do you have to export all irrelevant pages.
Applicable Scenarios: When do you need to batch convert specific pages of OFD to JPG images?
Converting OFD to JPG is not a simple format change; it usually serves subsequent tasks like viewing, uploading, archiving, print previewing, or system entry. Especially in office file circulation, JPG images are easier to preview directly in chat tools, web forms, approval systems, or image management software compared to OFD. Therefore, batch converting OFD files to JPG images can make file usage more flexible.
Typical scenarios include:
- Electronic Invoice Archiving: Batch convert the first page or first few pages of multiple OFD invoices to JPG, facilitating quick verification of header, amount, tax number, invoice date, and other information by financial personnel.
- Contract or Document Preview: Only export the first few pages of each OFD file for use as cover previews, table of contents previews, or document list previews, without generating a complete image package.
- Signature Page Extraction: If the signature/seal page is typically located at the end of the document, you can use "the last few pages" for batch conversion.
- Separate Processing of Odd/Even Pages: In scanning, file organization, or double-sided material verification, images can be exported separately by odd and even pages.
- Specific Range Export: For OFD files where only content from certain pages is needed, a custom range can be used to avoid exporting irrelevant pages.
Compared to manually opening an OFD reader and taking page-by-page screenshots, the advantage of using office software for batch processing lies in unified rules, stable output, and faster speed. As long as the page range is set once, the software will execute the same conversion rules for multiple OFD files in the import list, making it particularly suitable for standardized office workflows.

Before Processing: OFD files to be converted
From the pre-processing screenshot, you can see there are 4 OFD files in the current folder, named 1.ofd, 2.ofd, 3.ofd, 4.ofd. If these files are opened and exported to images one by one, it will generate a lot of repetitive clicking actions; if each OFD also has multiple pages, manually selecting pages will also increase the probability of errors.
The problem this tutorial aims to solve is: batch importing these OFD files into office software and converting only specific pages from them, rather than exporting all pages completely. This helps control the number of output images and allows you to get the really needed JPG files faster.
After Processing: Each OFD generates corresponding JPG results
In the post-processing screenshot, you can see that corresponding result folders or image results are generated in the output location, with numbers 1, 2, 3, 4 corresponding to the original OFD files, and the final format is JPG. This output method facilitates organization by original file source and facilitates subsequent copying, uploading, archiving, or sending to others for viewing.
For batch file conversion, whether the results are clear and whether they correspond to the original files is very important. Through a unified batch conversion process, you can avoid mixing up images exported from different OFD files, reducing subsequent organization costs.
Operation Steps: Batch convert specific pages of OFD files to JPG images
Step 1: Enter the "OFD to JPG Image" function
After opening HeSoft Doc Batch Tool , you can see multiple tool categories on the left, including Home, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, More Tools, etc. In the screenshot, the "More Tools" area is currently selected, and the main interface displays multiple format conversion functions.
Find "2. OFD to JPG Image" among the function cards; the card description is "Batch convert OFD files to JPG format images". Click this function to enter the OFD to JPG processing workflow.
The purpose of this step is to select the correct conversion tool. Since this article deals with OFD files and the target format is JPG images, you should select "OFD to JPG Image", not "OFD to PDF" or other CAD, XPS related functions.
Step 2: Add the OFD files to be processed
After entering the function page, the top displays the current task as "OFD to JPG Image". The interface provides action entries like "Add Files", "Import Files from Folder", "Clear", "More", etc. For a small number of files, you can use "Add Files"; if all the OFD files to be converted are already placed in a single folder, you can use "Import Files from Folder" to add the OFD files from that folder to the list at once.
In the screenshot, the file list has already imported 4 records, named 1.ofd, 2.ofd, 3.ofd, 4.ofd, with paths all located under the D:\test directory. The list also shows information like extension, creation time, and modification time, making it easy to confirm whether the imported files are correct. The summary area at the bottom shows "Record Count: 4", indicating that 4 OFD files will be processed in this batch.
In this step, it is recommended to check the file names and paths first to ensure no files of other formats are selected by mistake. If there are files in the list that do not need processing, you can remove the corresponding records using the delete icon in the right operation area; if imported incorrectly, you can also use "Clear" to re-add. After confirming the file list is correct, click "Next" at the bottom to enter the processing options settings.
Step 3: Set to convert only specific pages
After entering "Set Processing Options", the most critical area in the interface is "Processing Range". The screenshot shows selectable ranges including "All Pages", "The First Few Pages", "The Last Few Pages", "Odd Pages", "Even Pages", "Custom". These options cover common partial page export needs.
This example selects "The First Few Pages", and fills in 2 in the "Range" input box below, indicating that only the first 2 pages of each OFD file will be converted. If 4 OFD files are imported, the software will apply the same rule to these 4 files separately: each file will only export its first 2 pages as JPG images, and will not export page 3 and beyond.
If your actual needs differ, you can choose other processing ranges based on file characteristics. For example, if only signature pages are needed, select "The Last Few Pages"; if only front pages or back pages are needed, select "Odd Pages" or "Even Pages"; if you need to export non-contiguous or specific page ranges, you can configure it via the "Custom" option provided in the interface. Since page rules may differ for different tasks, it's best to check beforehand if the page count structure is consistent across all OFD files.
Step 4: Set image pixel density (PPI)
On the processing options page, you can also see the "Image Pixel Density (PPI)" setting item, with a value of 300 in the screenshot. PPI affects the clarity and file size of the output JPG images. Generally, the higher the PPI, the clearer the image, but the generated JPG files may also be larger; with lower PPI, the file size is smaller, but details like text, seals, and QR codes might not be clear enough.
For OFD files like electronic invoices, vouchers, and contracts that require clear text readability, 300 PPI is often a safe choice. It balances clarity and file size well, suitable for daily viewing, archiving, and uploading. If only creating thumbnail previews, you can reduce it based on actual needs; if printing or detail recognition requirements are high, you should choose a suitable pixel density while keeping the file size acceptable.
Step 5: Decide whether to stitch multiple pages together
At the bottom of the screenshot, you can see a switch for "Stitch multiple pages into one very long image". This option controls how images are presented when exporting a multi-page OFD. If this option is enabled, multiple pages might be stitched into one long image; if kept off, images are typically output per page.
Whether to enable it depends on your subsequent use. If you want to send the first few pages as a continuous preview image to others, the long image format is more intuitive; if per-page archiving, uploading, or verification is needed, it is recommended to keep per-page output for easier management and locating. In the screenshot, the switch is off, suitable for organizing pages as independent JPG results.
Step 6: Set the save location and start processing
After completing the page range, PPI, and stitching option settings, continue by clicking "Next". Based on the process bar, the subsequent steps are "Set Save Location" and "Start Processing". This means before the formal conversion, you need to specify the output directory for the JPG images to prevent the generated results from mixing with the original OFD files.
Once the save location is set, entering the "Start Processing" stage, the software will batch process the OFD documents in the file list according to the previously set rules. After processing is finished, go to the output directory to view the results, and you will see JPG images or result folders corresponding to the original files. Combined with the post-processing screenshot, the final generated results correspond to 1.ofd, 2.ofd, 3.ofd, 4.ofd, facilitating subsequent searching.
Frequently Asked Questions and Notes
1. Why choose specific pages instead of all pages?
If an OFD file has many pages but only the homepage, cover, signature page, or specific pages are needed, converting all pages will generate a large number of useless images, taking up storage space and increasing subsequent screening work. Choosing specific pages can make the output results more precise, which is especially suitable for batch file processing.
2. How to fill in the range for "The First Few Pages"?
This range is used to specify how many pages to convert starting from the first page of each OFD file. Filling in 2 in the screenshot means 2 pages are exported from the start of each file. If only the homepage is needed, fill in 1; if the first three pages are needed, fill in 3. It is recommended to confirm before input that all OFD files contain at least the corresponding number of pages, to avoid some files having insufficient pages and causing results inconsistent with expectations.
3. Is a higher PPI setting always better?
Not necessarily. High PPI improves image clarity but also increases JPG file size. For daily office archiving, data uploading, and text viewing, 300 PPI can be considered first; if the platform has limits on image size, you need to balance clarity and file size.
4. Do I need to back up OFD files before batch conversion?
Although the conversion operation usually generates new JPG images without directly modifying the original OFD files, when batch processing important archives, invoices, contracts, and other materials, it is still recommended to keep the original files. This way, even if the output settings do not meet expectations, you can re-adjust the parameters and convert again.
5. How to keep output results clear and organized?
It is suggested to first put the OFD files to be processed into a single folder with standardized naming; set a separate output directory for conversion; check the results by number or original file name after processing. This can prevent JPG images from different batches from getting mixed up and is more suitable for team collaboration and subsequent archiving.
Summary: Use batch processing to reduce repetitive work in OFD to image conversion
Batch converting specific pages of OFD files to JPG images is a very practical office scenario. It solves not only the format conversion problem but also the issues of batch file organization, page selection, and result archiving. Through HeSoft Doc Batch Tool , you can import multiple OFD files at once, uniformly set processing ranges like "The First Few Pages", "The Last Few Pages", "Odd Pages", "Even Pages", or "Custom", then set the image pixel density and save location, and finally batch generate JPG results.
If you frequently need to handle electronic invoices, OFD official documents, voucher materials, or archival files, it is recommended to standardize this type of operation: first gather the original files, then batch import, uniformly set the page range, and finally check the output results. This can significantly reduce the time cost of repeatedly opening files, manual screenshots, and saving page by page, and also lower the risk of missed or incorrect processing. You can now follow the steps in this article, organize the required OFD files into the same folder, and use the "OFD to JPG Image" function to complete the batch conversion.
