when there are a large number of OFD files and each file contains multiple pages of content, it is very inefficient to convert images one by one. This article HeSoft Doc Batch Tool For example, explain how to use the "OFD to JPG Picture" function to import multiple OFD files in batch, set the page processing range and picture pixel density PPI, and turn on "Splice Multiple Pages into a Long Picture". Finally, each OFD is output as a JPG long picture that is easy to view and upload, which is suitable for bills, invoices, vouchers and office filing scenarios.
Many office workers will encounter similar problems when processing OFD files: the files are in OFD format, but the receiver requires pictures; An OFD has multiple pages of content, and the upload system does not want to split it into multiple pictures. There are a lot of files, and manual conversion takes time and is easy to miss. OFD has become very common, especially in scenarios such as electronic invoices, electronic vouchers, fiscal bills, tax information, and government download files, but JPG images are still a more common and easier format to preview and deliver.
The problem to be solved in this paper is: how to batch generate JPG long maps with multiple OFD. In other words, instead of just converting OFD into ordinary pictures, multiple pages specified in each OFD are spliced into a long JPG picture. The result of this is: fewer files, continuous content, easy to view, and more suitable for uploading to business systems that only support pictures.
Use the office software in the screenshot below" HeSoft Doc Batch Tool "to make a demonstration. It is an office software for batch processing of documents. Its core value lies in the centralized execution of repeated file conversion, sorting, naming and other operations. For the high-frequency but tedious task of OFD to JPG long map, batch processing tools are more stable and time-saving than manual operation.
Applicable scenario: Why should OFD be converted into a JPG long map
OFD itself is suitable for electronic document storage and format fidelity, but in actual office circulation, not everyone is convenient to open OFD. Many systems, platforms, chat tools, email bodies or online forms have better compatibility with JPG images. Therefore, it is a common requirement to convert OFD into pictures.
And "turning into a long map" further solves the problem of multi-page content dispersion. For example, if an OFD invoice or voucher has 2 pages, if it is output as 2 pictures respectively, the subsequent upload, naming and verification will take one more step. If it is combined into a long picture, it can be viewed continuously from top to bottom after opening, with stronger information integrity.
Typical usage scenarios include:
- bulk electronic invoice processing:Convert multiple OFD invoice files to JPG for easy submission of reimbursement or filing.
- Multi-page voucher consolidation display:Split multiple pages of the same OFD into a long map to avoid page dispersion.
- Data upload platform:Some platforms only support jpg, jpeg and other image formats, and OFD needs to be converted first.
- Mobile access:The long picture can be viewed directly by sliding on the mobile phone, and no additional OFD reader is required.
- Bulk Archive Backups:After the OFD is converted into a picture, the thumbnail preview is more intuitive and convenient for later search.
If only one or two documents are converted, manual processing can be barely completed. However, if there are dozens of OFD, even if each one has multiple pages, batch operation is necessary. It not only saves time, but also makes the output format, page range, and clarity consistent.
Effect Preview: What Changes Before and After OFD File Conversion
Before processing, there are multiple OFD files in the folder. The screenshot shows four files: 1.ofd, 2.ofd, 3.ofd, and 4.ofd, which are all source files to be processed. At this time, if it is sent directly to others, the other party needs to be able to open OFD software; If you want to upload to a system that only supports pictures, you need to convert the format first.
After processing, the corresponding JPG images appear in the folder, such as 1.jpg, 2.jpg, 3.jpg, and 4.jpg. As can be clearly seen in the screenshot, 1.jpg is a long vertical image, indicating that multiple pages of content have been stitched into the same image. Other JPG files are also generated according to the source file name, which is convenient for one-to-one correspondence with the original OFD.
This effect is very suitable for office delivery: users do not need to open files page by page, nor do they need to merge multiple images manually. After the conversion is completed, each OFD corresponds to a result file, which is easier to view, transmit, and upload.
Operation steps: from importing OFD to outputting JPG long map
The following is a detailed description of how each step should be done and what results should be obtained after each step is completed in the order of screenshots of the software interface.
Step 1: Find the OFD to JPG function in the tool list
Open HeSoft Doc Batch Tool After that, look at the left navigation bar first. The interface provides multiple office processing categories, such as Word tools, Excel tools, PowerPoint tools, PDF tools, text tools, picture tools, and "more tools. Currently selected in the screenshot is More Tools ".
In the function card of the main area, find 2. Convert OFD to JPG Picture ". The note below the card reads "Batch convert OFD files to pictures in JPG format". This shows that the purpose of this function is very clear: batch conversion of OFD files into JPG images.
After clicking this function, the special OFD conversion task page will be displayed. Be careful not to select "OFD to PDF" here, because the goal of this article is not to generate PDF, but to generate JPG long maps.
Step 2: Import OFD files to be batch converted
After entering the "OFD to JPG Picture" page, you can see the two common entries of "Add File" and "Import File from Folder" at the top. If the files are scattered in different locations, you can use "Add Files" to select one by one; if the files are already in the same directory, it is more efficient to use "Import Files from Folder.
In the screenshot, four files have been successfully imported. The sequence number, name, path, extension, creation time, and modification time are displayed in the list. The file names are 1.ofd, 2.ofd, 3.ofd, and 4.ofd. The path is under D:\test \and the extension is ofd. The bottom summary area shows a record count of 4.
The purpose of this step is to create a list of files to be processed. The batch processing software performs the conversion tasks one by one based on this list. After importing, it is recommended to check three points: first, whether the number of files is correct; second, whether the extensions are all ofd; third, whether it contains files that do not need to be processed. If an error is found, you can delete the corresponding record in the "Operation" column, or use "Empty" and import it again.
After confirming that the list is correct, click "Next" at the bottom to enter the parameter setting page.
Step 3: Select the page processing range and decide which pages are involved in splicing.
After entering "Set Processing Options", the first thing you see is "Processing Range". The interface provides multiple choices: all pages, the first few pages, the last few pages, odd pages, even pages, custom. This setting determines which pages in each OFD are converted to images.
The screenshot selects "the first few pages" and fills in 2 in the "range" input box. This setting means that only the first 2 pages are processed per OFD file. This setting is appropriate if an OFD has many pages, but you only need the cover page and the first page content.
If your goal is to combine all the pages of the entire OFD into one long image, select All Pages ". If you only need the last attachment, you can select "Last Pages". If only odd or even pages are to be processed, you can also select from the options provided by the interface. For tasks with specific page requirements, the "Custom" option can be used, but the specific filling method shall be subject to the software interface prompt.
The more accurate the page range is set, the more the output results meet the requirements, and the unnecessary picture volume can be reduced.
Step 4: Set the picture pixel density PPI, taking into account the clarity and file size
Below the processing range, you can see the Picture Pixel Density (PPI) setting. The value in the screenshot is 300. PPI is related to the clarity of the output picture, especially affecting the display effect of details such as text, table line, two-dimensional code, red stamp, etc.
For office scenarios, 300 PPI is a more common choice. It is suitable for invoices, vouchers, contracts, notices, forms, and can ensure clear reading. If the PPI is set too low, the text may be blurred when zooming in after the long image is generated. If the PPI is set too high, the image will be clearer, but the file size may also increase and the processing time may be longer.
Therefore, it is recommended to determine according to the purpose: when used for formal filing, reimbursement submission, and contract retention, the 300 can be maintained; when used for temporary preview or internal rapid communication, it can be appropriately reduced as needed. In any case, it is best to test the output with a small number of files before processing a large number of files.
Step 5: Turn on the long image splicing switch to synthesize multiple pages of content into one image.
Continuing down, you can see the most critical setting of this article: "Splice multiple pages into a long picture". This option is marked with a red box in the screenshot, indicating that it is a key switch for OFD multi-page composition.
After this option is turned on, the software will splice multiple pages selected in the same OFD into a vertical long picture according to the page order. For example, if the previous setting is to process the first two pages, each OFD will eventually synthesize the first two pages into a JPG file. If you select All Pages, all pages of the OFD are merged into the same long image.
This setting is very different from ordinary OFD to JPG. Ordinary conversion may split a multi-page document into multiple images, while long image splicing is more suitable for scenes that require continuous reading. For documents such as electronic invoice details, attached page descriptions, approval materials, etc., long charts are easier to maintain content context.
Step 6: Set Save Location and Start Batch Processing
After completing the processing scope, PPI, and long image splicing settings, click "Next" at the bottom of the page ". As can be seen from the top process, the software also has two steps: "Set Save Location" and "Start Processing. The save location is used to specify the storage directory of the generated JPG file, and batch conversion is performed when processing starts.
It is recommended to create a separate output folder, such as "ofd to jpg results" or "long graph output". This has two advantages: first, the original OFD and the converted JPG will not be mixed together; Second, it is easy to check the number of files after the conversion is completed. For example, if four OFDs are imported, the corresponding JPG results can be seen in the output directory under normal circumstances.
After setting the save location, enter "Start Processing". The software will automatically process according to the file list and setting parameters, and the user does not need to open the OFD one by one. Once processing is complete, you can view the JPG long graph in the output folder.
Frequently Asked Questions and Precautions
1. When OFD is transferred to JPG long map, will the file name be easily confused?
From the renderings, the source files 1.ofd, 2.ofd, 3.ofd, and 4.ofd are converted to 1.jpg, 2.jpg, 3.jpg, and 4.jpg. For ease of management, it is recommended that the OFD file naming convention, such as using invoice number, date, customer name or business number as the file name before conversion.
2. What if the picture is too long after the multi-page OFD is turned into a long picture?
If there are a large number of OFD pages, the long image generated by selecting All Pages will be longer and the file size may be larger. At this time, it can be changed to "the first few pages", "the last few pages" or other ranges according to actual needs, and only the required pages are processed.
Why care about PPI?
OFD files often contain small text, forms, QR codes and seals. Too low PPI will affect recognition, too high PPI may increase file size. The 300 PPI is used in the screenshot, which is a more secure setting in the conversion of office materials.
4. Do I need to back up the original files before batch processing?
Although this operation converts OFD to JPG and does not directly indicate that the original OFD will be modified, it is still recommended to keep the original file before batch processing of important data. The conversion results can be placed in a separate folder for easy differentiation from the source files.
5. If you only want to convert a single page, do you still need to open long image splicing?
If the processing range contains only one page, the meaning of long image splicing is not obvious. If the processing range contains multiple pages, turn on this option to splice multiple pages into one picture. Whether to open, should be determined according to the actual output demand.
Summary: Batch conversion is used to reduce the duplication of OFD image processing.
The key to generating JPG long maps in batches of multiple OFD lies not in complex operations, but in setting correct batch rules at one time. The whole process can be summarized as follows: select the function of "convert OFD to JPG picture", import multiple OFD files, set the page range, set the picture pixel density PPI, turn on "splice multiple pages into a long picture", finally select the save location and start processing.
By HeSoft Doc Batch Tool , Users do not need to open OFD one by one, nor do they need to manually take screenshots, crop, splice and rename. For office workers who often deal with invoices, vouchers, government documents and archived materials, this batch conversion method can significantly reduce duplication of work, improve document sorting efficiency, and make the output more uniform.
If you are now facing a batch of OFD files and need to convert them into JPG long maps that are easy to view, upload and share, you can test the effect with several files according to the steps in this article, confirm that the page range and PPI are appropriate, and then process all the files in batches. This can not only ensure the output quality, but also make the whole office process more efficient and controllable.
