PPT to PPTX Converter

PPT to PPTX Converter

This tool accepts PPT presentations and returns PPTX files. Slide content is preserved, but slide transitions, in-slide animations, presenter notes and embedded media may not carry across intact.

How to convert PPT to PPTX

1. Select or drag PPT files into the upload area.
2. Confirm that the requested output format is PPTX.
3. Start the conversion and review the status of each file.
4. Download each result once processing has finished.

Convert several files in one batch

The interface currently accepts up to 10 files per batch. Files are processed one after another; duplicates, mislabeled files and damaged files may be skipped or reported as errors.

File size after conversion

The size depends on the number of slides and on the images and video embedded in them.

Check the result

Run through the whole deck and check fonts, image positions, charts and any animated slides. If presenter notes matter, check them separately.

Limits worth knowing

This tool changes the file format. It does not guarantee that every piece of metadata, every format-specific property or every embedded object survives the conversion. Keep the source file and test the result in the application where you plan to use it.

Frequently asked questions

Are animations preserved?

Possibly not. The two formats describe animation differently, so this is the part most likely to be lost.

What about video embedded in a slide?

It may not carry across. Check every slide containing video before you present.

Is my original file replaced?

No. The file on your device is left untouched.
