This tutorial is aimed at office users who need to process a large number of OFD documents, focusing on how to batch convert specified pages from multiple OFD files into JPG images. With HeSoft Doc Batch Tool , users can import multiple OFD files, select all pages, the first few pages, the last few pages, odd pages, even pages, or a custom range in the processing options, and set the image pixel density. The article combines screenshots of before processing, after processing, and the operation interface to help users quickly master the complete workflow of converting partial OFD pages to JPG, improving the efficiency of organizing invoices, contracts, and archival materials.
After many organizations adopt electronic office systems, they accumulate a large number of OFD format files, such as electronic invoices, electronic vouchers, electronic official documents, contract scans, and supporting materials. The OFD format is suitable for fixed layouts and archiving, but in some business systems, users may need to upload JPG images. During document review, they may only need to view certain pages of a file, rather than the entire OFD. This leads to a frequent question: How can you batch convert specified pages from multiple OFD files into JPG images?
Using traditional methods typically requires opening the first OFD file, locating the target pages, exporting or taking screenshots, then switching to the second file and repeating the process. The more files you have, the more obvious the repetitive work becomes, and page ranges, image clarity, and naming conventions may be inconsistent. This article introduces a processing method better suited for office scenarios: using the "OFD to JPG Image" feature in " HeSoft Doc Batch Tool " to import OFD files in batch and select the pages you need to convert within the processing range. This allows you to set rules once and execute them across multiple files simultaneously, significantly reducing manual effort.
Applicable Scenarios: Office Needs for Converting Specified OFD Pages to JPG
Electronic invoice and receipt processing. Many financial systems or reimbursement processes require attachments in image format, but the files received might be OFD. If each receipt only needs the first 1 or 2 pages, batch converting specific pages can quickly generate JPG attachments.
Contract and agreement preview. Contract-type OFDs usually contain main text, attachments, signature pages, and other sections. Initial material review may only require the cover page, key information pages, or the final signature page. Partial page conversion can reduce the output of irrelevant pages.
Digital organization of archival materials. Archivists often need to generate image previews or index maps for each OFD file. Exporting only the first few pages helps quickly identify material content while reducing storage usage.
Batch upload to systems that do not support OFD. Some web backends, mobile systems, and collaboration platforms do not support direct OFD preview but do support image formats like JPG and PNG. Converting OFD pages to JPG improves compatibility.
Unified image clarity. The size and clarity of manual screenshots are often inconsistent. Using a batch conversion tool and setting the image pixel density (PPI) can make the output results more standardized.
Effect Preview: File Changes Before and After Batch Conversion
Before processing, the folder contains multiple OFD files. The example screenshot shows 4 files pending processing, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd. These types of files usually require an OFD reader to open. If you need to view them directly in a common image viewer, business system, or chat tool, you must first convert them to images.
After processing is complete, the output results become a result directory or folder related to JPG images. The screenshot shows corresponding results like 1, 2, 3, 4, etc., with clear JPG identifiers, indicating that each source OFD has generated a corresponding image. For batch processing, this one-to-one correspondence makes it easier to verify: you can check if the output is complete by matching the number of source files with their corresponding names or numbers.
It should be noted that this article focuses on "converting partial pages of OFD files to images." That means the number of pages in the output depends on the range you set in the processing options. For example, if you set it to convert the first 2 pages, it will not output all pages of the entire OFD, saving both time and reducing the number of images.
Step 1: Open the Batch Processing Tool and Enter the OFD to JPG Function
First, launch HeSoft Doc Batch Tool . As seen in the screenshot, the top-left corner of the software interface displays " HeSoft Doc Batch Tool ," and the left side features categories like 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, and More Tools. The main area shows multiple conversion function cards.
Select "2. OFD to JPG Image" from the function cards. The description for this card is "Batch convert OFD files to JPG format images." This step is crucial because OFD-related conversions can include different target formats, such as OFD to PDF and OFD to JPG. If the final requirement is images, you should enter "OFD to JPG Image."
After entering this function, the subsequent operations will center around the batch file list. Unlike single-file conversion tools, HeSoft Doc Batch Tool is more suitable for processing multiple files at once, reflecting the value of office software in batch processing files and reducing repetitive labor.
Step 2: Import Multiple OFD Files and Check the Processing List
After entering the "OFD to JPG Image" page, you can see the top process divided into 4 steps: Select records to process, Set processing options, Set save location, and Start processing. You are currently in the first step, which is adding the OFD files you want to convert to the list.
The upper-right area of the page provides two common options: "Add Files" and "Import Files from Folder." If the OFD files you want to convert are scattered in different locations, you can click "Add Files" to select them one by one; if the files are all in the same folder, using "Import Files from Folder" is more efficient. For scenarios involving financial receipts, project materials, or batches of contracts, it is usually recommended to first gather the OFD files for processing into a single folder before importing them uniformly.
After importing, the table displays information for each record, such as serial number, name, path, extension, creation time, and modification time. The example shows 4 records, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd, all with the ofd extension, and the summary at the bottom shows a record count of 4. Users can use this information to confirm if the files were imported correctly.
Before formally proceeding to the next step, it is advisable to perform a list check: are any OFD files missing? Were any irrelevant files mistakenly imported? Is the path the target directory for this processing? Does the record count match expectations? If you find records that do not need processing, you can remove them using the delete button in the operation column; if you need to start over, you can use "Clear." After confirming there are no errors, click the "Next Step" button at the bottom of the page.
Step 3: Select Processing Range to Convert Only Specified Pages
In the second step, "Set processing options," the most critical area is the "Processing Range." The screenshot lists multiple range options: All pages, First few pages, Last few pages, Odd pages, Even pages, and Custom. These options determine which pages from each OFD file will be converted into JPG images.
The example shows "First few pages" selected, and the number 2 entered in the "Range" input box. This setting means: for every OFD file in the file list, only convert the first 2 pages. Assuming 1.ofd has 8 pages, 2.ofd has 3 pages, and 3.ofd has 12 pages, as long as the page count meets the condition, they will all output JPG images according to the rule of the first 2 pages. This ensures consistent batch processing rules, making it very suitable for batch extraction of the first and second pages.
If your business requirement is not the first 2 pages, you can adjust according to the actual situation. For example, if you only want to export the first page, select "First few pages" and enter 1; if you only want to export the last few pages, like signature pages or approval pages, select "Last few pages"; if you need to extract single or double pages, use "Odd pages" or "Even pages"; if the page range is more complex, you can try the "Custom" option and fill in the range as required by the software interface.
The key point of this step is not to convert all pages, but to let the software process only the pages you really need. For a large number of OFD files, this can significantly reduce the number of output images. For instance, if each OFD has 20 pages and you only need the first 2, the output volume is reduced to about one-tenth, making subsequent checking and uploading much easier.
Step 4: Set Image Pixel Density and Whether to Stitch into Long Image
On the same processing options page, you can also see the "Image Pixel Density (PPI)" setting. The value in the screenshot is 300. PPI can be understood as one of the important parameters for image output clarity. For OFD files containing text and seals, such as receipts, forms, and contracts, clarity affects subsequent reading, recognition, and printing results.
Generally, 300 PPI is a common setting for converting office documents to images, suitable for archiving, previewing, printing, and uploading. If it's only for quick viewing, a lower PPI might also meet the needs; if you need to zoom in to view details, you can choose a higher clarity setting. Note that the clearer the image, the larger the file size typically is, and the storage space used during batch processing will also increase. Therefore, it's recommended to balance clarity and file size according to business needs.
Below the page, there is also a switch for "Stitch multiple pages into one long image." As seen in the screenshot, this switch is off. When off, it better aligns with the conventional office habit of outputting page by page, which is also convenient for checking and uploading individually. If the business scenario requires viewing multiple pages as one continuous long image, you can enable it as needed. However, the example in this article assumes the switch is off, meaning the selected pages are converted into JPG image results.
After completing the processing range and image parameter settings, click the "Next Step" button at the bottom to proceed to the save location setting.
Step 5: Select Save Location and Start the Conversion Task
According to the process at the top of the page, step 3 is "Set save location," and step 4 is "Start processing." Although the provided screenshot does not show the detailed interface for the save location, it's clear from the batch processing flow that after completing the processing options, you need to specify where the converted JPG images will be saved, and then start executing the task.
It is recommended to follow one principle when choosing the save location: keep source files and result files separate. For example, if the source files are in the "test" folder on the D drive, you can create a separate folder named "OFD to JPG Results." This makes it easy to quickly check after processing is complete and avoids mixing output images with original OFD files. If you need to reconvert later, you only need to clear the results directory without accidentally deleting source files.
After entering the "Start processing" step, execute the conversion according to the interface prompts. Since you have already imported multiple OFD files at once and uniformly set the processing range, the software will automatically process all records using the same rules. For users who process electronic receipts or batches of materials daily, this method is much more stable than manually opening, saving as, and taking screenshots.
Common Questions and Precautions
1. What is the difference between OFD to JPG and OFD to PDF? OFD to PDF converts a fixed-layout file into another document format, suitable for continued reading or printing as a document; OFD to JPG converts pages into images, suitable for uploading to systems that only support images, or for previewing, archiving, and screenshot substitution scenarios. This article chooses "OFD to JPG Image."
2. Can I convert only the last page? From the processing range in the screenshot, you can see the "Last few pages" option. If you only need the last page, you can usually select this range and enter 1. This is suitable for extracting signature pages, approval pages, or final confirmation pages.
3. Will errors occur if each OFD has a different number of pages during batch conversion? It is common for different files to have inconsistent page counts. When setting ranges for the first few pages, last few pages, odd/even pages, or custom ranges, you should understand the processing results in context with the actual file page counts. If some files have insufficient pages, the actual output is subject to the software's processing results and prompts. It is recommended to test with a small sample first for important batch tasks.
4. What should I do if the output JPG images are too large? You can control this from two directions: first, only convert necessary pages, rather than selecting all pages; second, adjust the PPI according to actual usage. The clearer the image, the larger the file size might be. For general previewing and uploading, it's advisable to choose appropriate parameters on the premise of being clear and readable.
5. Why keep the switch for stitching multiple pages into a long image turned off? Turning it off is usually more suitable for page-by-page management, with one image per page, making it convenient for uploading, viewing, and verifying. A long image is suitable for continuous reading, but if the business system requires page-by-page uploading, outputting per page is more convenient.
6. Do I need to back up OFD files before processing? Conversion typically reads OFD files and generates JPG results, and should not directly modify source files. However, when processing important business materials, retaining the original OFD is always a safer practice. It is recommended to save the output results in a separate folder and avoid overwriting the original files.
Summary: Batch Converting Specified OFD Pages to JPG Makes Document Organization More Efficient
When you need to convert multiple OFD files to JPG images, especially only part of their pages, using HeSoft Doc Batch Tool can significantly improve efficiency. The overall process is not complicated: first enter the "OFD to JPG Image" feature, import multiple OFD files; then select a page range in the processing options, for example, the first few pages and enter 2; next, set the image pixel density and whether to stitch into a long image; finally, set the save location and start processing.
This method is suitable for organizing large quantities of OFD files like electronic invoices, receipts, contracts, official documents, and archival materials. Its value lies in turning repetitive operations into unified rules, allowing the software to execute them automatically in batch, which saves time and reduces the risk of missed conversions, incorrect conversions, and unclear screenshots. If you are currently manually exporting OFD pages one by one, you can first process a few files according to the example in this article, confirm the output effect, and then execute the conversion on the entire batch of files.
