This article describes how to use HeSoft Doc Batch Tool to batch convert specified pages of multiple OFD files into JPG images. The tutorial focuses on common needs such as "exporting only the first few pages, last few pages, odd pages, even pages, or custom pages," combining before-and-after effect images and software interface steps to help users reduce repetitive operations like opening OFD files one by one, manually taking screenshots, or saving as images. It is suitable for batch image processing scenarios involving electronic invoices, electronic official documents, contracts, archival materials, and other OFD files.
In daily office work, OFD files are becoming increasingly common. For example, electronic invoices, electronic official documents, electronic contracts, and archived materials may all be saved in OFD format. However, often we don't need to convert an entire OFD file into images, but only need specific pages from it, such as the first 2 pages, the last few pages, odd pages, even pages, or certain specified pages of each OFD file. If there are only one or two files, manually opening them and exporting page by page is acceptable; but when facing dozens or hundreds of OFD files, repeatedly opening, selecting pages, exporting images, and organizing folders becomes very time-consuming and prone to missing or selecting wrong pages.
This article aims to solve this problem: how to use the office software " HeSoft Doc Batch Tool " to batch convert specific pages of multiple OFD files into JPG images. The core value of this software is batch processing files, reducing repetitive work, and is especially suitable for finance, administrative, archive, legal, and project data management personnel who need to uniformly process a large number of documents. The following will combine screenshots and explain, based on the actual operation process, how to complete the conversion of specific pages of OFD to JPG images.
Applicable Scenarios: When do you need to batch convert specific pages of OFD to JPG
Converting OFD to JPG is not just a format conversion; it is very practical in many office workflows. For example, when financial personnel receive a batch of OFD electronic invoices, they only need to export the first page image of the invoice for upload to the reimbursement system; when archivists organize electronic official documents, they only need to convert the cover or key pages of each OFD into images for easy index or thumbnail generation; when project staff summarize contract materials, they might only need to extract the signing page, first page, or last page of each contract as materials for quick verification.
If using a regular reader to open OFD files one by one and then manually taking screenshots or saving as images, it is not only inefficient but also difficult to unify the image size, clarity, naming, and save location. Through a batch processing tool, you can import multiple OFD files at once, set the processing range and image pixel density in the same interface, and then uniformly output JPG images. This ensures consistent processing results and reduces errors caused by manual operation.
The example in this tutorial is batch processing 4 OFD files and setting to convert only the first 2 pages of each file. This scenario is typical: it is neither a full-page conversion nor a single-file conversion, but executing the same selective page export rule for multiple OFD files.
Effect Preview: Multiple OFD files before processing, corresponding JPG images obtained after processing
Before processing, there are 4 OFD files to be converted in the folder, named 1.ofd, 2.ofd, 3.ofd, and 4.ofd respectively. Each of these files may contain multiple pages of content, but we do not need all pages this time; instead, we only extract some pages within a specified range.
After batch conversion, the output results can be seen to have formed corresponding image results by file. The screenshot shows output folders or result items numbered 1, 2, 3, and 4, and the obvious JPG identifier can be seen on the right side, indicating that the OFD files have been converted to JPG image format. For batch processing, this output method makes subsequent viewing, archiving, uploading, or secondary editing more convenient.
From the comparison before and after processing, it can be seen that OFD files that originally needed to be opened one by one have been converted into more universal image files after batch processing by the software. JPG images can be directly used in most systems, web pages, chat tools, office software, and business platforms, with better compatibility than OFD. Especially when the business system does not support direct OFD uploads but supports uploading image formats like JPG or JPEG, this type of batch conversion function is very practical.
Operation Step 1: Enter the "Convert OFD to JPG Image" function
After opening HeSoft Doc Batch Tool , you can see multiple document batch processing functions on the main interface. The left side is the function classification, 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. This article uses the "Convert OFD to JPG Image" function located in More Tools.
In the screenshot, the "Convert OFD to JPG Image" function card is highlighted, with the description "Batch convert OFD files to JPG format images". This aligns with our goal: batch convert OFD documents to JPG images, with the ability to further set the processing page range subsequently.
Operation Purpose: Enter the correct function module to ensure that subsequent imports are OFD files and the output is in JPG image format.
Expected Result: After clicking or selecting "Convert OFD to JPG Image", enter the task configuration page for this function, where you can start adding the OFD files to be processed.
Operation Step 2: Add OFD files to be batch converted
After entering the "Convert OFD to JPG Image" function, the current task name is displayed at the top of the interface. The operation process is divided into 4 steps: Select records to process, Set processing options, Set save location, Start processing. The first step is "Select records to process", which means importing the OFD files to be converted into the software list.
From the screenshot, the top right corner of the interface provides operation buttons such as "Add File", "Import files from folder", "Clear", "More". For a small number of files, "Add File" can be used; if the files are concentrated in a folder, using "Import files from folder" is more efficient. After importing, the files will be displayed in the list, including information like serial number, name, path, extension, creation time, modification time, etc.
In the example, 4 OFD files have been imported: 1.ofd, 2.ofd, 3.ofd, 4.ofd. Their paths are all located in the test directory on the D drive, the extension is displayed as ofd, and the total record count at the bottom is 4. This step is important because the objects for batch conversion all need to enter the task list first, and the subsequently set page range and image parameters will be applied to these files.
Operation Purpose: Import multiple OFD files at once to create a batch conversion task.
Expected Result: All pending OFD files are displayed in the file list, with the record count matching the actual number of files. If files not needing processing are found to be imported, they can be removed using the delete icon on the right side of each row; if the list needs to be reorganized, you can also use "Clear" and re-add.
Operation Step 3: Set to convert only some pages
After importing the files, click "Next Step" at the bottom to enter "Set processing options". This is the key step of this tutorial, because what we want to achieve is not converting the entire OFD to JPG, but batch converting specific pages of OFD files to images.
On the processing options page, you can see the "Processing Range" area. The software provides multiple page range options: All pages, The first few pages, The last few pages, Odd pages, Even pages, Custom. In the screenshot, "The first few pages" is selected, and the number 2 is filled in the "Range" input box, indicating that only the first 2 pages of each OFD file are converted.
This setting is suitable for many common scenarios. For example, the first two pages of each OFD file contain the abstract, cover, basic information, or the main content of an invoice, and only these pages need to be exported as JPGs. If your requirement is to export the last few pages, you can select "The last few pages"; if you only need odd or even pages, you can also directly select the corresponding option; if the page range is more special, you can choose "Custom".
Operation Purpose: Control the actual page range converted for each OFD file, avoid outputting irrelevant pages, and reduce the number of images and subsequent organization costs.
Expected Result: The software will extract the same range of pages for each OFD file in the import list according to the selected rule. In this example, all 4 OFD files will only extract the first 2 pages for JPG conversion, not all pages.
Operation Step 4: Set Image Pixel Density PPI and decide whether to stitch a long image
In the same processing options interface, you can also see the "Image pixel density (PPI)" setting item, which has a value of 300 in the screenshot. PPI usually affects the clarity of the output image. For images intended for printing, archiving, text recognition, or uploading to platforms with clarity requirements, 300PPI is a common choice; if only used for quick preview or internal communication, it can be adjusted appropriately according to actual needs.
Below that is the switch for "Stitch multiple pages into one very long image". From the screenshot, this switch is in the off state. When off, it is usually understood that multiple pages will be output as separate images, making it easy to view and manage page by page; if enabled, it might merge multiple pages into one long image, more suitable for creating previews or browsing multiple pages at once in certain scenarios. Since the goal of this example is to convert specific pages into JPG images and keep the results easy to organize, keeping it off is a safer choice.
Operation Purpose: Set the clarity of the output image and confirm whether to stitch multi-page results into a long image.
Expected Result: The output JPG images will be generated according to the set PPI; if long image stitching is not enabled, each page will be output in a way more convenient for archiving and viewing.
Operation Step 5: Set the save location and start batch processing
After completing the page range and image parameter settings, continue to click "Next Step". According to the interface flow, it will subsequently enter "Set save location", and then "Start processing". Although the screenshot does not show the detailed interfaces for setting the save location and starting processing, it can be clearly seen from the top flow that these two steps are the standard process of the software.
When setting the save location, it is recommended to choose an empty folder or a dedicated output directory for this task, such as "D:\OFD to JPG Result". The advantage of this is that the result files will not be mixed with the original OFDs, making subsequent checking, compression, uploading, or archiving more convenient. For tasks involving a large number of files, it is advisable to include a date or project name in the save path for easier traceability.
After completing the settings and entering the start processing phase, the software will batch execute the OFD to JPG task based on the previously imported file list and page range settings. After processing is complete, you can view the corresponding image results in the output location. Combined with the post-processing screenshot, it can be seen that corresponding output results were generated for each source file, facilitating continued management by file name.
Frequently Asked Questions and Notes
1. Why choose "specific pages" instead of "all pages"?
If each OFD file has many pages, but you only actually need the first few, last few, or specified pages, choosing specific pages can significantly reduce the number of output images, save disk space, and reduce subsequent screening time. This point is very obvious especially when batch converting dozens or hundreds of OFD files.
2. How should the number in "The first few pages" be filled in?
The number represents the number of pages to extract from the beginning of each OFD file. Filling in 2 in the screenshot means taking the first 2 pages of each file. If only the first page is needed, fill in 1; if the first three pages are needed, fill in 3. It is recommended to confirm whether the page structure of the OFD files is consistent before processing.
3. Is a higher PPI setting always better?
A higher PPI usually means clearer images, but the file size may also be larger. 300PPI is suitable for most office archiving and clear viewing needs. If you are only making thumbnails or quick previews, you can lower it according to the actual situation; if you need higher-definition images, you can also adjust it in combination with business requirements.
4. How are output results named and managed?
From the effect after processing, the software generates corresponding results for different source files. It is recommended that users keep OFD file names standardized before conversion, such as naming them with invoice numbers, contract numbers, dates, or project codes. This makes it easier to match the original files after conversion.
5. What should I do if I find OFD files that don't need processing after importing?
On the right side of the file list, you can see the delete operation icon to delete a single record; if many import errors are made, you can also use the "Clear" button at the top to re-import.
Summary: It is more efficient to use a batch processing tool to convert specific pages of OFD to JPG
Batch converting specific pages of OFD files into JPG images is a typical repetitive office task. Manual processing is not only time-consuming but also easily affects subsequent work due to inconsistent page selection, messy save locations, and non-uniform image clarity. Through HeSoft Doc Batch Tool , you can first batch import OFD files, then uniformly set the processing range, such as the first 2 pages, set the image pixel density PPI at the same time, and finally output the JPG results centrally.
If you frequently need to process electronic invoices, electronic official documents, contract archives, or other OFD materials, it is recommended to hand over this type of operation to batch processing software. By following the steps in this article, you can turn the repetitive labor of "opening one by one, exporting page by page" into a standard process of setting up once and completing in batch, thereby significantly improving office efficiency.
