Try the 3 PowerPoint File Repair Tool to Fix Corrupted PowerPoint Files Quickly

Quick Free & Official Methods to Fix a Corrupted PowerPoint File

Wondering how to fix corrupted PowerPoint file problems without spending anything? Start here. Both of these methods are free, take only a few minutes, and are best for minor damage such as a bad save or an interrupted transfer.

Method 1: Use PowerPoint's built-in "Open and Repair"

Microsoft has added this command to Word, Excel and PowerPoint just for this situation.

• Open PowerPoint. Do not double click on the corrupted file.

• Click File > Open > Browse to open the folder that has the presentation. Don't pick it from the Recent list, as this skips the Open dialog and hides the repair option.

• Click the file once, then click the small arrow to the right of the Open button.

• Select Open and Repair.

• If the deck opens, save it right away with a new name.

  

Method 2: Open PPT/PPTX with Google Slides, LibreOffice Impress, or WPS Office

Open and Repair may give up but another program may still be able to read the deck. Google Slides, LibreOffice Impress and WPS Office each have their own engine for opening presentation files, so one of them might be able to fix PowerPoint file errors that have broken Microsoft’s app. Some fonts or animations might get disturbed so expect that.

• Open Google Slides and click”File” > “Open”.

  

• Go to the Upload tab and upload your PPTX or PPT file.

  

• If it loads, go to File > Download > Microsoft PowerPoint (.pptx) to get a fresh copy.

• Open Impress and choose File > Open and then the corrupted file.

• Do File > Save As and select the PowerPoint (.pptx) format.

• Open WPS Presentation and choose File > Open.

• Select the file, then save it again as a .pptx.

FAQs about Repairing PowerPoint File

Yes, a few. PowerPoint's own Open and Repair command costs nothing, and so does opening the file in Google Slides, LibreOffice Impress, or WPS Office and saving a fresh copy.
