PPT
PPT is the binary presentation format of Microsoft PowerPoint 97 to 2003. Many older decks, training materials and templates in company archives are still .ppt files, which current PowerPoint opens in compatibility mode.
PPTX
PPTX is the modern Microsoft PowerPoint presentation format based on Office Open XML. It can contain slides, text, images, charts, tables, media, and speaker notes. It opens in PowerPoint, Keynote, Google Slides and LibreOffice Impress.
FILE FORMATS
SOURCE
PPT is PowerPoint's binary format from PowerPoint 97 to 2003. It stores slides, layouts, pictures, charts, speaker notes and embedded media in a single binary file. Current PowerPoint opens PPT in Compatibility Mode, and many shared drives still hold decks in this format.
TARGET
PPTX has been PowerPoint's default since 2007. It is a ZIP of XML files describing slides, layouts, themes, pictures, charts and notes, standardized as Office Open XML. PowerPoint, Keynote, Google Slides and LibreOffice Impress all open it.

USE CASES
Practical workflows where PPT to PPTX conversion is useful.
Edit old decks without compatibility mode
PowerPoint opens .ppt files in compatibility mode. The .pptx opens as a normal presentation.
Keep working in Google Slides or Keynote
Import the .pptx into Google Slides or Keynote to keep working on old slides.
Reuse slides from old training material
Text, pictures and tables come across, so slides from older courses can be copied into a current deck.
Keep the presenter's notes
Speaker notes are carried over, so the script stays with each slide.
Keep backup slides hidden
Hidden slides stay hidden in the .pptx, so they still stay out of the slide show.
Modernize a presentation archive
Convert legacy .ppt files before moving them to SharePoint, OneDrive or Google Drive.
Co-edit an old deck
Co-authoring in PowerPoint for the web works with .pptx files, so convert the deck before editing it together.
Upload to a platform that needs PPTX
Webinar and learning platforms that accept only .pptx take the converted deck.
Process slides with modern tools
Scripts and tools that read .pptx, such as python-pptx or slide-text extractors, can work with the converted deck.
Rescue decks from old backups
Presentations copied from old CDs or backup drives become .pptx files for current software.
SUPPORTED FILES
PowerPoint 97-2003 presentations are supported.
Decks from older PowerPoint versions.
Speaker notes are carried over.
Converted into the PPTX.
Bring legacy templates into the current format.
Upload several PPT files and download the PPTX files as a ZIP.
TROUBLESHOOTING
Most differences come from fonts and features the target format handles differently.
01
The document is laid out by LibreOffice, and fonts the server doesn't have are replaced with similar ones. Embed fonts in the original to avoid this.
02
Open the file, save a copy without a password and upload that copy.
03
A cut-off or broken upload can't be read. Download or copy the original again.
04
Some older animation effects are mapped to their closest modern equivalent.
05
Very old embedded media formats may not play in current PowerPoint. Re-insert the video as MP4.
06
PPTX can't hold macros. Save as .pptm in PowerPoint if you need them.
PowerPoint, Excel and LibreOffice can save PPT as PPTX once installed. dragdropdo does the same conversion in the browser, on any device.
