How to repair a PowerPoint presentation online

To repair a damaged Microsoft PowerPoint presentation from a corrupted *.ppt, *.pptx file, you need to do the following:

  1. Select the presentation file by clicking the Select file button
  2. Wait for the damaged file to be repaired
  3. Download the repaired PowerPoint file

Presentations repaired from damaged Microsoft PowerPoint files are saved by the service to a new file with a .pptx extension.

The repairing of Microsoft PowerPoint presentations of any size and version is now possible on any device with a web browser.

Note:

  • The service does not recover password-protected presentations
  • If the correct recovery of an object (image, table, etc.) is impossible, the service will save them as separate files. The user will then be able to manually add these files to the recovered presentation

Practical testing of damaged PowerPoint presentation recovery: comparison of software and online services

Recovery Toolbox systematically conducts independent testing of software and online tools designed to recover PowerPoint presentations created in Microsoft Office. The purpose of these tests is to determine how effectively each solution copes with recovering data from real damaged files, as well as to identify ways to improve the quality and speed of the process in our own services and programs.

Practical testing of damaged PowerPoint presentation recovery

The testing is based on real user materials uploaded by customers via the cloud-based PowerPoint presentation recovery platform: https://powerpoint.recoverytoolbox.com/online/. Such tests are conducted on average once or twice a year, which allows us to track trends and identify the strengths and weaknesses of various recovery methods.

For analysis, at least 300 presentations are selected in each test cycle, differing in format (.pptx, .ppt), Microsoft PowerPoint version, size, and type of damage. Files can have a variety of defects, from broken slide structures and distorted images to lost text data and damaged macros.

Real users send materials that have been damaged as a result of a variety of factors — incorrect program shutdown, saving failures, damage to data carriers, or virus attacks. This selection makes the testing as close as possible to real-life conditions and allows us to objectively assess which solutions are truly capable of restoring the presentation to working order.

Preparation and selection of test files for testing PowerPoint presentation recovery

For testing, we used the most diverse set of damaged PowerPoint presentations possible. The files were not filtered or pre-sorted in any way — absolutely everything that had been downloaded in the weeks leading up to the test was included. This approach allowed us to make the experimental conditions as close as possible to real-life scenarios, where the user needs to recover data without any prior preparation.

The test set included presentations with different types of damage:

  • files that cannot be opened at all;
  • documents with partially damaged slide structure;
  • presentations with lost graphic elements or formatting;
  • files with damaged embedded media objects;
  • documents that require a password to be entered.
Preparation and selection of test files for testing PowerPoint presentation recovery

The set also included presentations created in different versions of PowerPoint (from old *.ppt formats to modern *.pptx), with different sizes and structures. We deliberately did not exclude password-protected files in order to assess how the utilities cope with such cases.

Software and services involved in the test

During testing, we checked the performance of both desktop programs and cloud-based online services for recovering presentations.

These included:

Each utility and service were tested using the same set of test files. This ensured a fair comparison and allowed us to objectively evaluate:

  1. How accurately the original structure of the presentation is restored;
  2. The preservation of text, graphics, tables, and charts;
  3. The correctness of formatting and design template restoration;
  4. the program's ability to work with passwords and partially damaged data;
  5. the time required to process the document.

Thanks to this approach, we obtained a clear comparison that shows which solutions are best at recovering PowerPoint files under different conditions.

Results of practical testing of tools for recovering PowerPoint files

During the study, the results of various programs and online services designed to recover PowerPoint presentations were collected and analyzed. All the indicators obtained were systematized and entered into a comparative table, which made it possible to objectively evaluate the effectiveness of each solution.

The table reflects how successfully a particular utility or web service coped with the recovery task, taking into account both the degree of damage to the original file and its complexity (the presence of animations, embedded multimedia, graphic elements, and complex layouts).

This approach helps not only to determine the best tool overall, but also to choose the optimal option for a specific scenario — whether it is recovering simple slides or complex projects with a large amount of multimedia data.

Below is a summary comparison table obtained as a result of testing.

Service or program % of files successfully recovered Price for recovering 1 file Comment
Online service Recovery Toolbox https://powerpoint.recoverytoolbox.com/online/ ~71% $10 per 1 GB Universal utility for all devices and systems.
Recovery Toolbox for PowerPoint ~69% $25 Only for Windows
Online service Online.repair ~68% $10 per 1 GB In addition to the service, there is a Windows tool: PowerPoint Repair Kit
Online service OnlineFileRepair.com ~67% $5 per 1 GB
SecureRecovery® for PowerPoint ~23% $59.99 There is an online service
DataNumen PowerPoint Repair ~17% $129.95 There is a batch mode for processing large numbers of PowerPoint files
Stellar Repair for PowerPoint ~11% $59 Crashes very often
Built-in Open and Repair feature ~7% Free Works well for simple damage
Additional information and notes:
  • DataNumen PowerPoint Repair supports processing multiple damaged presentations at once, which is convenient for mass file recovery. Batch mode saves time by eliminating the need to load each document separately.
  • The SecureRecovery® for PowerPoint license is comparable in price to the cost of recovering a single file through an online service. This may not be cost-effective if you only need to recover a single document, but it is cost-effective for large volumes of work.
  • Stellar Repair for PowerPoint often freezes during operation and sometimes displays uninformative or confusing error messages, which can complicate the recovery of presentations for inexperienced users.
  • The standard Open and Repair feature built into PowerPoint is suitable for fixing minor damage, such as minor saving errors or damage to the file structure but not the content. However, it is usually insufficient for serious damage.

Ze Mane 09-08-2025

Nice app, resolved my issue by recovering a Powerpoint file from a CD.

Sol David 08-04-2025

I hired the service to recover a PowerPoint file with more than 80 slides.
Only 8 pasted figures were recovered, which were public and easily accessible.
All the written content I produced was not recovered.
I was very dissatisfied with the service, which is paid.
This should be made clear to everyone in advance, that is, recovery is not guaranteed. This is only stated at the end, when the minimal recovery of the file is sent.
We're looking for a complete service, not a partial one. If that were the case, the charge itself should be partial.

Marie-Laure Hilgert 11-10-2024

I was working in a car on my computer. My file was on my Toschiba portable storage linked on my PC with an USB cable. Internet was given by my smartphone, we were driving on a french highway. I added many slides on my powerpoint and I saved my work many times during the journey. After the last slide, I recorded one last time and I shut down my PC as usual and before removed my portable storage (1 To). At home, I used my big PC on my worktable : I put my portable storage with the USB link, I found my files but Powerpoint refuse to open it.

North Platte 10-10-2024

I was using the PowerPoint all day and when I finished for the day, it said something about a new version of the presentation and then all of a sudden I could not open it and it said that it was damaged and not repairable

gion 09-30-2024

Very good recoverd. Thanks a lot!!!

biuro 02-26-2023

The presentation is poorly restored.
The images were not inserted into the presentation, but saved in a separate archive.
I had to add each picture separately and fit it to the page.

Monte 01-03-2023

Hello. I use Windows11 and OneDrive on an ASUS Zenbook. For some reason, there is the occasional time when I cannot 'wake up' the computer by clicking the mouse or pressing ctlr+alt+delete. In those instances I have to hold down the power button for a few seconds to reboot the computer. On one of those occasions, I had a PowerPoint file open with autosave turned off. The file contained images, one video, text, and several animations. It was after my computer had restarted (because of not being able to be woken up) that the file was not able to be opened with a message prompt of something to the affect of being damaged. I clicked on 'repair' which did not solve the problem. It's hard to say what the key contributing factors were to the file becoming damaged.

Allen Reyes 04-14-2021

PowerPoints files repaired. The program could not fix files with a size less than 17kb.

Elisabeth Stewart 03-22-2021

PowerPoint prompting to repair the file, but cannot fix :)
Before that, I believed that Microsoft can do everything, until I met Recovery Toolbox.
Our world needs new heroes. Thanks for the corrected file.

Antechinus 02-09-2021

If my budget allowed me to donate to you, I would! I was able to repair an ancient and unique presentation on dentures

Korbyn Sterling 01-13-2021

The program handled a couple of files, but couldn't fix all of them. Out of 10 files I fixed only 3. Considering that the files were recoverd .PPTX files from the computer's hard drive, which was completely wiped clean, I am satisfied.

Kenzo Nico 12-28-2020

This is the first time I come across the need to restore a PowerPoint presentation. I myself am not a pro in computers, but with the Recovery Toolbox for PowerPoint wizard, I managed to fix the errors immediately.

Jambeau 12-15-2020

I downloaded a demo version of the product before purchasing. I selected a damaged .PPT file in the program, the program immediately detect errors in it. The fix took less than a minute, and then the program opens the presentation right after the "Submit" button. Thank you, everything worked out for me.

Michel from France 10-04-2020

I was satisfied with the service (10.75 €) but the formatting of the PPT file could not be respected. It still saves me a lot of time to rework the document. Thank you

Jenesis Nathan 08-11-2020

A very simple program for recovering works in Microsoft PowerPoint. Satisfied. thank

GrizliczYokel 06-29-2020

I had a PowerPoint exam for children with drawings, but it cannot be opened and showed errors. After fixing the errors, I received a restored version of the presentation, where only the text was repaired! Pictures were fixed in a separate folder, from which you need to drag them to the desired slide! Also in the presentation I had navigation icons (back, forward, to the main page), since these pictures were recovered separately, I had to manually put links for these buttons on each slide!

Marryyer10 06-15-2020

While working with the presentation, the error "Microsoft PowerPoint has encountered a problem and needs to close" surfaced and the program closed. After reinstalling MS PowerPoint, he stopped opening my presentation because it was damaged.
Second error "PowerPoint found unreadable content in EssayHomeland.pptx." After restoring the document, I received two files - the restored presentation and media files in a separate ZIP archive. Now you need to insert the pictures into the slides manually.

Larinepie15 06-01-2020

When trying to cut and paste to a removable disk, an error occurred, and the file moved to the device with corruption. Now it is not possible to open it in the program, PowerPoint 2003 cannot read the .PPT file. The program was able to restore the file, but some slides lost animation.

Sublimal 04-03-2020

After analyze broken .PPTX file, I press "Transmit", process of export the recovered data to the Microsoft PowerPoint begin, but some media files were saved to a separate folder. It is good that the duration of the animation duration in the presentation was correctly restored.
