This article focuses on the office task of "batch extracting the first 2 pages of OFD files and converting them to JPG images," explaining how to complete the operation through HeSoft Doc Batch Tool . The tutorial covers applicable scenarios, before-and-after effects, feature entry points, file import, processing range settings, PPI settings, and saving output, helping users quickly master the method for batch converting partial pages of OFD files to images. It is suitable for scenarios such as electronic invoices, contracts, official documents, and vouchers that require unified export of key pages.
In office document processing, the OFD format is becoming increasingly common, especially for electronic bills, government documents, contract archives, and business vouchers. The actual need many users encounter is not "converting the entire OFD file into images," but rather "only needing the first few pages of each OFD file." For example, exporting only the first 2 pages of each file for preview, extracting only the first page and detail page of each voucher, or batch-converting key pages of a group of OFD files into JPGs for uploading to a business system.
Using traditional methods requires opening OFD files one by one, then manually selecting pages, exporting, or taking screenshots. This process is acceptable with a small number of files, but once the number of files increases, it consumes a significant amount of time. Even more troublesome is that manual operation can easily miss a file or select the wrong page number. This article will use "extracting the first 2 pages of each OFD file and converting them to JPG images" as an example to introduce how to use HeSoft Doc Batch Tool to complete batch operations.
Applicable Scenarios: What is the Use of Batch Extracting the First Few Pages of OFD Files
Converting only the first few pages of OFD files is a very typical batch office requirement. For instance, financial staff need to convert the first page and attached pages of a batch of OFD electronic invoices into JPGs; administrative staff need to create image previews of the first 2 pages of multiple OFD notices; archival staff need to generate key page images for each OFD file for quick retrieval; project staff need to insert the first few pages of OFD materials into summary documents or system attachments.
The characteristic of these scenarios is that the processing rule is very clear: each file exports the same number of pages. Rather than repeating the same operation dozens of times, it is better to use batch processing software to complete it in one go. The value of HeSoft Doc Batch Tool lies in standardizing repetitive file processing actions, allowing users to focus their energy on rule confirmation and result checking instead of spending time on mechanical operations.
Effect Preview: Batch Output 4 OFD Files as JPG Images
Before processing, there are 4 OFD source files in the folder, namely 1.ofd, 2.ofd, 3.ofd, and 4.ofd. They represent the batch of OFD documents to be processed uniformly this time. For these types of files, manually exporting the first 2 pages one by one would require repeatedly opening 4 files and performing multiple export operations.
After processing is complete, you can see that the output results have been generated. In the example, the results are presented in a numbered manner, corresponding to the original files, and the generated files are JPG images. Because "the first few pages" was selected and "2" was filled in the settings, the output results come from the first 2 pages of each OFD file, not all pages of the entire document.
From this effect, it can be seen that batch processing not only completed the format conversion but also performed page filtering. For users, this is more practical than simply converting OFD to images, because it directly yields image results that meet business requirements.
Operation Steps: Batch Convert the First 2 Pages of OFD to JPG
Step 1: Open the Software and Select the OFD to JPG Image Function
After opening HeSoft Doc Batch Tool , find the "OFD to JPG Image" function in the feature list. In the screenshot, this function is located at item 2 in the main area, with the description "Batch convert OFD files to JPG format images." This indicates that the function is not designed for single file conversion, but for batch file processing.
The purpose of selecting this function is to enter the OFD image conversion task. The left side of the software provides entry points for different types of office tools, including document, spreadsheet, presentation, PDF, image and other related tools. Since the current goal is to convert OFD files to JPG images, you should enter "OFD to JPG Image", and not select other format conversion entries.
Step 2: Add Multiple OFD Files to the Processing List
After entering the function, you can select single or multiple OFD files by "Add File", or batch-import files from a specific directory into the list using "Import Files from Folder". For scenarios like this tutorial involving the unified processing of multiple OFD files, the folder import method is recommended for priority, as it is more time-saving and aligns better with the batch processing approach.
The screenshot shows 4 files have been imported, with the table displaying 1.ofd, 2.ofd, 3.ofd, and 4.ofd in rows. Each record shows information such as name, path, extension, creation time, and modification time. There are two key points to check here: first, whether all extensions are ofd; second, whether the number of records matches the actual number of files to be processed. The bottom of the example shows a record count of 4, indicating that 4 files have been added to the task.
If an incorrect file is found to have been imported, you can use the delete entry in the operation column to remove it; if the overall imported content is incorrect, you can use "Clear" to reselect. After confirming the list is correct, click "Next" at the bottom to enter the processing parameter settings.
Step 3: Select "The First Few Pages" and Fill in 2
In the "Set Processing Options" interface, the most critical part is the "Processing Range". The screenshot shows optional ranges including all pages, the first few pages, the last few pages, odd pages, even pages, and custom. To achieve "batch extract first 2 pages" in this example, select "The first few pages" and fill in 2 in the range input box.
This setting will be applied to every OFD file in the task list. That is, 1.ofd will export the first 2 pages, 2.ofd will export the first 2 pages, and 3.ofd and 4.ofd will also export the first 2 pages. Users do not need to set this repeatedly for each file. For batch office work, this method of unified rule processing is very important, as it can avoid selecting the wrong page count for a file during manual operation.
If your requirement is not the first 2 pages, you can also modify the range using the same method. For example, fill in 1 if only the first page is needed; fill in 5 if the first 5 pages are needed. If you need the end pages, you can select "The last few pages"; if you want to filter by odd or even pages, you can select "Odd pages" or "Even pages"; if the page number rules are more complex, you can use the "Custom" option.
Step 4: Set Image Pixel Density PPI
In the same interface, you can see "Image Pixel Density (PPI)", with the example value being 300. This setting determines the clarity of the exported JPG image. For OFD documents with a lot of text, tables, stamps, QR codes, etc., a higher PPI helps retain details. The 300 PPI in the example is a common output setting for document images, suitable for archiving, viewing, and printing scenarios.
It should be noted that the clearer the image, the larger the file size may be. If it is only for temporary preview, the PPI can be lowered according to actual requirements; if it is for formal archiving or submission to a system, it is recommended to test with a sample file first to ensure clarity meets requirements before batch converting.
Step 5: Decide Whether to Stitch into a Long Image Based on Needs
Below the screenshot, there is also a switch for "Stitch multiple pages into one very long image". In the example, this switch is in the off state, indicating that the exported pages will not be merged into a long image. For most scenarios requiring page-by-page use, upload, or archiving, keeping it off is sufficient.
If your business requires merging the first 2 pages into a single continuous image, you can enable this option according to actual needs. However, before formal processing, it is recommended to test the output effect first to confirm whether the long image meets subsequent system upload or reading requirements.
Step 6: Set Save Location and Start Processing
After completing the processing option settings, click "Next" to enter the save location settings. It is recommended to choose a clearly named output folder, such as named by project name, date, or batch. This way, after conversion is complete, you can quickly locate the results, and it's easy to distinguish them from the original OFD files.
After setting the save location, continue to "Start Processing". The software will process the 4 OFD files in the list sequentially and generate results according to the settings like "first 2 pages, JPG format, 300 PPI". After processing is complete, open the output directory to view the corresponding JPG images.
Common Questions and Precautions
1. What if an OFD file has fewer than 2 pages?
Before batch processing, it is recommended to understand the page count of the source files as much as possible. If page counts vary greatly among different files, you can test the output results with a small number of files first, confirming that the software's handling method meets expectations before processing the complete batch.
2. How should the output directory be chosen?
It is recommended not to output directly to a cluttered directory. You can create a dedicated folder to store the results of this batch conversion, naming it something like "Project X OFD First 2 Pages JPG". This makes subsequent checking, packaging, and uploading more convenient.
3. Why check the record count after importing?
Batch processing acts on all records at once. If a file is missed during import, the results will be incomplete; if a file is imported by mistake, unnecessary images may be generated. Therefore, the record count and file names should be confirmed before clicking next.
4. Will JPG images and original OFD files affect each other?
Looking at the conversion process, the software reads the OFD and generates JPG image results. For ease of management, it is recommended to keep the original OFD files and place the output images in a separate directory. This way, even if you need to reset the page number or PPI later, you can process from the original files again.
5. Does the page rule need to be uniform before batch conversion?
Yes, it does. Batch processing is most suitable for files with consistent rules. If some OFDs require the first 2 pages and others require the last page, it is recommended to process them in batches, setting different rules separately, to avoid mixing different requirements in a single task.
Summary: Use Batch Tools to Quickly Convert the First Few Pages of OFD to JPG
The core process for batch extracting the first 2 pages of OFD files and converting them to JPG images is not complicated: enter the "OFD to JPG Image" function, import multiple OFD files, select "The first few pages" in the processing range and fill in 2, set an appropriate PPI, then choose a save location and start processing. The entire process only requires setting the rule once, and it applies to all files.
For users who frequently process OFD files like electronic invoices, contracts, official documents, and vouchers, HeSoft Doc Batch Tool can effectively reduce the time cost of repeatedly opening files and manually exporting pages. It is recommended to test the page range and clarity with a few samples before large-scale batch processing, confirming everything is correct before executing the batch. This ensures accurate results and significantly improves office efficiency.
