This article describes how to batch convert multiple OFD files into JPG images and splice multiple pages in each OFD into a long image. It is suitable for processing OFD files such as electronic invoices, electronic vouchers, government documents, and filing materials. By HeSoft Doc Batch Tool , you can import multiple OFD at a time, set the number of conversion pages, picture pixels per inch, and turn on the "splice multiple pages into a long picture" option to reduce the repeated operations of opening, screenshots and saving as one by one.
In daily office, OFD files are becoming more and more common, such as electronic invoices, electronic vouchers, government receipts, filing documents, etc. may use OFD format. The problem is that many collaboration scenarios are not convenient to view OFD directly: some people do not have OFD readers installed, some platforms only support JPG, PNG and other picture formats when uploading materials, and some filing systems hope to combine a multi-page file into a long picture for preview, check and forwarding.
If there are only one or two files, it can be barely completed by manually opening OFD, taking screenshots page by page, and splicing the growth chart again. However, when the number of files becomes dozens or hundreds, this method will be very time-consuming and prone to problems such as page leakage, wrong sequence, inconsistent resolution, etc. What this article wants to solve is this pain point: using office software" HeSoft Doc Batch Tool ", batch convert OFD files into JPG pictures, and splice multiple pages into a long picture.
As can be seen from the screenshots, the software is located in batch processing of documents, and the left side contains Word tools, Excel tools, PowerPoint tools, PDF tools, picture tools, more tools and other categories. This tutorial uses the "Convert OFD to JPG Picture" function in "More Tools" and focuses on how to import multiple OFDs, set the page range, set the pixel density of the picture, and turn on the long picture stitching option.
Applicable scenario: when do you need to turn OFD into a long picture
batch convert OFD pages into a JPG long map, suitable for the following types of office needs.
1. Electronic invoice or electronic bill filing. Many electronic invoices and reimbursement vouchers will be provided in OFD format. If the reimbursement system, financial system, or database only accepts image formats, you can batch convert OFD to JPG first. For multi-page OFD, after long image splicing is enabled, each file corresponds to a picture, which is more intuitive when looking up.
2. Government materials, notices and receipts are shared. OFD is a format file, which is suitable for formal document storage, but it is not necessarily convenient for the receiver to open. After turning into JPG, you can view it directly in the chat tool, browser, mobile phone photo album or web page system.
3. Multi-page content requires continuous preview. Some OFD files contain multiple pages of material. If you export multiple pictures separately, you need to switch back and forth when viewing. After splicing multiple pages into a long picture, users only need to scroll down to read the complete content.
4. Batch process a large number of files. When the number of documents is large, the value of batch processing of office software is very obvious. Through one import, a set of parameters, unified output, can reduce duplication of labor, improve conversion efficiency, but also to ensure that the output picture specifications are more consistent.
Effect preview: before processing is multiple OFD, after processing to get JPG long map
before processing, there are multiple OFD files in the folder, such as 1.ofd, 2.ofd, 3.ofd, 4.ofd. They are all source files that need to be converted in batches.
after processing, you can see that the output result becomes a JPG image, such as 1.jpg, 2.jpg, 3.jpg, 4.jpg. The first result image shows a clear vertical long image effect, indicating that multiple pages of content have been stitched into the same image. For multi-page OFDs, this output makes it easier to view, send, and archive.
it should be noted that the software will generate the corresponding picture file according to the imported OFD file. In other words, batch processing does not combine all OFDs into a general picture, but converts each OFD file into a corresponding JPG picture according to settings. When an OFD contains multiple pages and long picture splicing is enabled, the pages of the OFD will be spliced into a long picture.
Operation Steps: Batch Splice OFD File Pages into a JPG Long
PictureStep 1: Enter "OFD Convert to JPG Picture" Function
open HeSoft Doc Batch Tool On the left, you can see multiple tool categories. According to the screenshots, currently under the category of "more tools", the main area shows a number of conversion function cards, including "OFD to PDF", "OFD to JPG picture", "XPS to PDF" and so on.
This time, OFD needs to be converted into JPG picture, so click "2, OFD is converted into JPG picture". The description below the function card is "Convert OFD files to JPG images in batches", which is consistent with the goal of this tutorial.
the purpose of this step is to enter the correct batch conversion task page. After entering, the software will switch to a special OFD to JPG process, and then you can add files, set processing options, set the save location and start processing.
Step 2: Add the converted OFD file
after entering the "OFD to JPG Picture" page, you can see buttons such as "Add File", "Import File from Folder", "Empty" and "More" at the top. The page process is divided into four steps: select the records to be processed, set processing options, set the save location, and start processing.
If you only need to select a few specified files, you can click "Add Files". If a folder contains many OFD files, it is more appropriate to click "Import Files from Folder", which can reduce the operation of selecting one by one.
from the list in the screenshot, you can see that four OFD files have been successfully imported: 1.ofd, 2.ofd, 3.ofd, and 4.ofd. Information such as serial number, name, path, extension, creation time and modification time are displayed in the table, and the number of records shown in summary at the bottom is 4. This indicates that the pending file is ready.
In this step, it is recommended to carefully check the file list to confirm whether it contains all OFD files that need to be converted. If you find import errors, you can use the delete icon to the right of each line to remove individual files, or if you need to re-select, you can use the "Clear" button to clear the current list and re-import.
Step 3: Enter the processing option and set the page range
once the file is imported, click Next at the bottom of the page to go to Set Processing Options ". As you can see in the screenshot, the processing range provides a variety of options, including "all pages", "the first few pages", "the last few pages", "odd pages", "even pages", "custom", etc.
in the screenshot, the "first few pages" are currently selected, and 2 is filled in the "range" input box, indicating that only the first two pages are processed for each OFD file. This setting is suitable for situations where you only need to export the first page of the file, the summary of the first two pages, or the main page of the invoice.
If you want all pages of the OFD to be converted into a long graph, select All Pages ". If only the last few pages are needed, you can select "the last few pages"; If there is a special page number requirement, you can set it according to the "custom" option provided by the interface. The page range determines the content that will eventually participate in the transformation and splicing, so this is a very critical step before the output of the long graph.
Step 4: Set the picture pixel density PPI
in the same processing options page, you can see the "Picture Pixel Density (PPI)" setting, which is 300 in the screenshot. PPI affects the sharpness and file size of the output JPG image. Generally speaking, the higher the value, the clearer the picture, but the generated file may also be larger; when the value is lower, the picture is smaller, but the details such as text, seal, and QR code may not be clear enough.
For invoices, certificates, contracts, receipts and other OFD documents that need to see the text and seal clearly, 300 PPI is a more common choice. It is balanced between clarity and file size. If it is only used for quick preview, it can be appropriately reduced; if it is used for printing or long-term archiving, it can maintain a high pixel density according to actual requirements.
Step 5: Turn on "Splice Multiple Pages into a Long Picture"
the core setup for this tutorial is here. Below the screenshot there is an option: "Splice multiple pages into a long picture", next to the switch button. After this switch is turned on, multiple pages in the same OFD file that meet the page range will be combined into a vertical length map.
For example, if an OFD has two pages and the page range is set to the first two pages, after long image splicing is enabled, the output result will be one JPG long image instead of two scattered JPG images. In this way, there is no need to switch pictures when viewing, which is suitable for sending to others for quick check and uploading to a system that only allows single pictures.
If this option is not turned on, the software will usually output pictures separately according to the page. After opening, the focus is "multiple pages in one". Therefore, if your goal is to turn multiple OFD pages to one long map, be sure to make sure that this switch is on.
Step 6: Set the save location and start processing
after the processing options are set, click "Next" and follow the page flow to enter "Set Save Location". This is used to specify where to save the converted JPG image. It is recommended to select an output folder that is easy to identify. For example, create a new JPG Long Chart Output folder next to the original OFD folder to facilitate subsequent verification.
After setting the save location, proceed to the "Start Processing" step. The software will batch execute OFD to JPG according to the file list and processing options imported earlier. After the processing is completed, go to the save directory to view the results, you should be able to see the JPG image corresponding to the source file.
Combined with the renderings, 1.ofd, 2.ofd, 3.ofd, and 4.ofd before processing are finally generated corresponding to 1.jpg, 2.jpg, 3.jpg, and 4.jpg. For multi-page documents, you will get a vertical long graph effect after splicing is turned on.
frequently asked questions and notes
on1. why output is jpg, rather than png or pdf?
the name of the function used in this tutorial is "Convert OFD to JPG Picture". The screenshot also clearly shows that this function is used to convert OFD files to JPG format pictures in batches. Therefore, this article focuses on JPG output. If you need other formats, you should look for the corresponding function in the software, but don't mistakenly think that PDF or PNG will be output directly in the current function.
2. Will selecting "the first few pages" affect the long picture content?
will. Long graph stitching will only splice pages that are included in the processed range. The first 2 pages are selected in the screenshot, so the final long image only contains the first 2 pages of each OFD. If you want to convert all pages, you need to select All Pages ".
3. Is the PPI setting higher the better?
not necessarily. The higher the PPI, the better the clarity is usually, but the file size will also increase. For OFD with more text, seals, and QR codes, it is recommended to use about 300 PPI; if it is only used for online preview, it can be adjusted according to the actual situation.
4. What do you need to check before batch conversion?
it is recommended to check three points: first, whether the file list is complete; second, whether the page range meets the requirements; third, whether "splice multiple pages into a long picture" has been turned on ". These three items will directly affect the final output.
