There are two easy ways to convert a PowerPoint presentation into a video with Synthesia.

1. Use the PowerPoint to Video Converter

Upload your .ppt or .pptx file using the converter tool at the top of the page. Synthesia automatically transforms your slides into a complete video draft with scenes and a generated script. You can choose a template, add context to define your video’s objective, tone, language, and speaker, and then fully customize every element, including the AI avatar, voiceover, script, media assets (even AI-generated clips), and interactive features.

2. Import your PowerPoint into Synthesia

Alternatively, you can import your PowerPoint directly into a new video project. Each slide becomes a scene background, while text elements remain editable within Synthesia. Speaker notes are imported as your video script, and fonts are detected automatically. If any fonts are missing, you can replace them or upload the originals to maintain your presentation’s design.

Both methods make it simple to turn static slides into engaging, presenter-led videos - no recording or complex editing required.

Converting a PowerPoint to video makes your content more engaging, accessible, and shareable. Viewers retain 95% of a video's message compared to just 10% from reading text, and videos are easier to watch across devices. With 78% of people watching videos weekly and 55% daily, turning slides into video helps you reach and hold attention more effectively.

Yes, PowerPoint lets you export slides as an MP4, but the result is essentially an automated slideshow with limited interactivity and no presenter. With Synthesia, you can upload your PowerPoint and transform it into a professional AI video complete with realistic avatars, natural-sounding voiceovers, and custom branding. Once finished, you can easily export your video as an MP4 or share it via a link. This makes your presentation more engaging and scalable than a simple slideshow conversion.

Yes, Synthesia lets you convert PPT files to video with AI-generated voiceovers. Just type your narration script, and Synthesia will add lifelike audio in over 140 languages. No need to record your own voice.

Yes, when you import a PowerPoint file within the Synthesia app, speaker notes are automatically converted into natural AI voiceovers that sync perfectly with your slides. The platform extracts your speaker notes and transforms them into a script that AI avatars deliver with realistic speech patterns and gestures.

The synchronization happens automatically, but you maintain full control to edit the script, adjust timing, or choose from over 1000 voices across 140+ languages and accents. This eliminates the need for manual recording or complex audio editing, turning hours of production work into a simple upload and customize process that delivers professional results.

Yes, you have complete control to edit and customize your video after importing PowerPoint slides into Synthesia. The platform provides an intuitive editor where you can modify text, swap AI avatars, adjust layouts, and add new elements like images, screen recordings, or AI-generated video clips. You can also change voiceovers, select different languages, add background music, and apply your brand colors and fonts to ensure the video matches your style.

The editing process is as simple as working with PowerPoint itself, but with powerful video capabilities. You can rearrange scenes, add animations and transitions, insert interactive elements like clickable buttons, and even generate new visuals using AI. This flexibility means your PowerPoint to video conversion is just the starting point for creating truly engaging, professional video presentations.

Synthesia supports both .ppt and .pptx PowerPoint file formats with a maximum file size of 50MB. The platform also accepts other document formats including PDF, DOC, DOCX, and TXT files, giving you flexibility in how you bring your content into the video creation process.
