Free online PPTM to MP4 converter

Some presentation systems and devices accept MP4 video but cannot open a macro-enabled PowerPoint deck. Exporting a PPTM as video makes its slides playable in common media players and easier to share without requiring PowerPoint.

What the PPTM format is

PPTM is the macro-enabled presentation format used by Microsoft PowerPoint. It stores slides, images, transitions, animations, audio, and potentially VBA macros; PowerPoint is its primary creator, and the format is also encountered when someone shares a presentation that needs macros.

What the MP4 format is

MP4 is a video container commonly used for H.264 video and AAC audio. It can play on phones, computers, browsers, and media players, but it is a rendered recording: viewers cannot edit its slides or run the presentation’s macros.

How to convert PPTM to MP4

1. Upload the PPTM file on the converter page. Several files can be added for batch conversion; check the per-file size limit shown on the page.
2. Set show each page for before converting.
3. Convert the file or batch, then download the resulting MP4 file(s).

Offline with desktop software

OBS Studio and LibreOffice provide a free recording workflow on Windows, macOS, and Linux. Open the PPTM in LibreOffice Impress, check that its slides display correctly, and start the slide show. In OBS, add a display or window capture source, start recording, and play the presentation through its slides. Stop recording when finished. OBS commonly saves recordings as MKV; use File → Remux Recordings in OBS to create an MP4. This method records in real time, so advance slides and play audio during capture.

Microsoft PowerPoint can export the presentation directly. On Windows, open the file and choose File → Export → Create a Video, select a resolution and whether to use recorded timings and narrations, then choose Create Video and save as MP4. In PowerPoint for Mac, use File → Export and choose MP4 as the file format.

Quality and limitations

PowerPoint’s export is generally the better choice when the deck relies on PowerPoint-specific animations, transitions, narration, or VBA-driven behavior. LibreOffice may render some PowerPoint features differently, and macros may not work as they do in PowerPoint. OBS captures only what appears during playback, so its output depends on the display resolution, recording settings, and slide timing.
