The PPSX format is suitable for direct playback of presentations and is commonly used in meetings, training, teaching, and exhibition displays. If you have a large number of PPTX files that need to be converted to PPSX, manually saving each one as a different format is very inefficient. This article, through before-and-after processing screenshots and the HeSoft Doc Batch Tool operation interface, details how to open the PowerPoint tool, select "PowerPoint to PPSX," add files or import files from a folder, check the pending records and continue to complete the conversion, helping users quickly perform batch format conversion for multiple PowerPoint files.
Many office workers encounter a detail problem when organizing presentation materials: during the file creation phase, the PPTX format is usually used because it is convenient for editing and modification; however, during the delivery, playback, or archiving phase, they want the files to be in PPSX format, so that recipients can directly start the slideshow by double-clicking. Converting a single file is not difficult, but if a project contains many PowerPoint files, such as courseware, product introductions, flowchart presentations, team activity slides, etc., opening each one and saving it as PPSX becomes a time-consuming mechanical task.
This article focuses on "how to batch convert multiple PowerPoint files to PPSX show format" and highlights the process of using the office software HeSoft Doc Batch Tool for batch conversion. It is an office software designed for batch document processing, suitable for handling common file tasks involving Word, Excel, PowerPoint, PDF, images, etc. For the PPTX to PPSX requirement in this tutorial, it can centrally import multiple files and convert them uniformly, avoiding the need to repeatedly open PowerPoint.
Applicable Scenarios: Why Batch Convert PPTX to PPSX
PPTX is the commonly used editable format for PowerPoint presentations, suitable for creating content; PPSX is the PowerPoint Show format, more suitable for display and playback. The difference between the two determines their different roles in the office workflow: PPTX is for "editing," and PPSX is for "presenting."
Batch conversion is especially valuable in the following scenarios:
- Unified distribution of meeting materials: Conference staff need to convert multiple agenda, report, and proposal slides into show format.
- Delivery of training courseware: Training departments want trainees or instructors to play the files directly after receiving them, rather than entering the editing interface.
- Organization of teaching courseware: Teachers need to convert a set of PPTX courseware to PPSX for quick opening in the classroom.
- Corporate promotional display: Marketing, sales, and branding teams need to prepare presentations on different topics as directly playable versions.
- File archiving management: After a project ends, generate a PPSX copy of the final PPTX version to keep as a display version.
The larger the number of files, the more obvious the advantage of batch processing becomes. Manual saving not only takes a lot of time but can also lead to some files not being converted, being saved to the wrong location, or having confusing names due to fatigue.
Effect Preview: Changes in File Extensions Before and After Conversion
The image below shows the file status before processing. Multiple PowerPoint files are arranged in the folder, all with the .pptx file extension. The red annotation highlights the "pptx" extension, indicating that these files are still in the presentation editing format.

As can be seen from the file names, the content types of this batch of files are not exactly the same, covering topics like calendars, processes, book reviews, PDCA, service infographics, and team building. If manual conversion is used, the same action needs to be repeated for each topic file, resulting in low efficiency.
The image below shows the effect after processing. The same batch of files has been converted to the .ppsx format, and the thumbnails also display them as playable PowerPoint file statuses. The red annotation highlights the "ppsx" extension, indicating that the batch conversion has been completed.

This comparison is very intuitive: the main file names have not been arbitrarily changed; the primary change is the extension from .pptx to .ppsx. For office scenarios requiring the unified delivery of show files, this is exactly the result that batch conversion aims to achieve.
Operation Steps: Batch Converting PowerPoint to PPSX
Step 1: Open the software and select the PowerPoint tool
After launching HeSoft Doc Batch Tool , first look at the function navigation bar on the left. In the screenshot, you can see that "PowerPoint Tools" is located in the left category and is already selected. Since the objects to be processed this time are PowerPoint slide files like PPT, PPTX, etc., you must enter this category first.
After entering, various PowerPoint conversion tasks will appear on the right, including converting to JPG images, PPT, PPTX, PPTM, PPS, PPSX, PPSM, POTX, PDF, XPS, HTML web pages, and more. Different tasks correspond to different output formats. For this tutorial, select "PowerPoint to PPSX".

The operational goal of this step is to switch the software processing mode to PPSX conversion. The expected result is that after clicking this function, you enter the task page for "PowerPoint to PPSX". If other functions are selected, such as converting to PDF or JPG, the output format will be different, so pay attention to the function name.
Step 2: Enter the conversion page and import the files to be processed
After entering the task page, the top title displays "PowerPoint to PPSX". The upper right corner of the page provides two main import methods: "Add Files" and "Import Files from Folder".

If the files to be processed are scattered in different locations, you can use "Add Files" and select multiple files as needed. If these PPTX files are centrally stored in one folder, it is more recommended to use "Import Files from Folder". This allows you to add the relevant files from the folder to the list at once, which is more in line with the batch processing approach.
The screenshot shows that 8 records have been successfully imported. The list includes columns for number, name, path, extension, creation time, modification time, and actions. The extension column displays pptx, indicating that the current files to be converted are indeed in PPTX format.
Step 3: Verify file names, paths, and extensions
Checking before batch processing is very critical because the software executes the conversion based on the records in the list, so the accuracy of the list directly affects the final result. It is recommended to check in the following order:
- Check "Name": Confirm that all files needing conversion are present, such as Calendar illustration.pptx, Change Management Chart.pptx, etc.
- Check "Path": Confirm that the files originate from the correct folder to avoid importing old versions or test files.
- Check "Extension": Confirm that they are mainly PowerPoint files like pptx, rather than other file types imported by mistake.
- Check "Actions": If a record does not need to be processed, you can remove it from the list using the delete icon on the right.
The purpose of this step is to ensure that the targets for batch conversion are correct. The expected result is that all files in the list need to be converted to PPSX, with no extra files and no missing files.
Step 4: Clear or re-import as needed
In the screenshot, you can also see the "Clear" button at the top. This is suitable when there are import errors, the wrong folder was selected, or you want to reorganize the pending processing list. Compared to deleting entries one by one, clearing and re-importing is faster.
It is important to note here that batch processing tools can significantly improve efficiency, but only on the premise that the input list is accurate. If incorrect files are imported, the software will faithfully batch-process the incorrect files. Therefore, clearing and re-importing are not superfluous steps but important means of controlling the quality of the batch task.
Step 5: Click Next to continue setting the save location
After confirming the list is correct, click the "Next" button at the bottom. The interface flow shows that subsequent stages include "Set Save Location" and "Start Processing". In other words, importing files is just the first step; you also need to determine where the converted PPSX files will be saved next.
It is recommended to save the converted files to a separate folder, especially when the original PPTX files still need to be retained. This offers three benefits: first, it avoids mixing original and output files; second, it facilitates comparing the number of files before and after conversion; third, it makes subsequent packaging, uploading, or sending easier.
Step 6: Complete processing and check the PPSX results
After the save location is set, follow the interface flow to enter the start processing phase. Once processing is complete, open the output folder and check if the file extensions are .ppsx. You can also randomly double-click a few files to confirm that they open in show mode and check if the slide content is complete.
If a large number of files have been converted, it is recommended to verify based on the total file count. For example, if there are 8 records in the import list, you should see a corresponding number of PPSX files in the output folder. If the main file name is consistent with the original file and the extension has changed to PPSX, it usually indicates that the conversion task has been completed normally.
Frequently Asked Questions or Precautions
Is PPSX suitable as a replacement for PPTX?
PPSX is suitable for playback and distribution, but it is not recommended to completely replace PPTX. PPTX is more suitable for subsequent editing, while PPSX is more suitable for presentation. In actual office work, it is advisable to keep the original PPTX manuscript and simultaneously output a PPSX version.
Does it support converting PPT to PPSX?
The function name in the screenshot is "PowerPoint to PPSX", indicating it is designed for PowerPoint file conversion. The example files in this article are PPTX. For other PowerPoint formats like PPT, it is recommended to rely on the actual software import and processing results, and do not skip testing for important tasks.
Why check the extension after importing?
The extension helps you quickly determine the file type. The most concerning issue in batch tasks is mixing in irrelevant files, so checking the extension can reduce the risk of misprocessing.
What if the converted files cannot be opened?
You can first confirm whether the original PPTX files can be opened normally, and then check if the PPSX files in the output directory were generated completely. If the file itself is corrupted, the format conversion might also be affected. For important files, it is recommended to back them up first before batch processing.
How to improve accuracy when there are many files?
It is suggested to first gather the files to be converted into a dedicated folder, and then use "Import Files from Folder". This not only reduces the chance of missing selections but also facilitates subsequent quantity verification.
Summary: Leave Repetitive Format Conversion to Batch Processing Tools
Batch converting multiple PowerPoint files to PPSX essentially means delegating the repetitive labor of "saving as individually" to an office software to complete uniformly. Through HeSoft Doc Batch Tool , you can select "PowerPoint to PPSX" in the PowerPoint Tools, then batch-add PPTX files via "Add Files" or "Import Files from Folder", check the list, click Next, set the save location, and complete the processing.
