Can Synthesia turn a powerpoint into a video?
Yes. Synthesia can turn a PowerPoint (or PDF) into a video: you import the file, each slide becomes a scene, and you add an AI avatar and voiceover to narrate. Its AI can even draft the script from your slides. The result is a narrated presenter video in minutes, editable by changing text and re-rendering.
Why — the first-principles explanation
Turning slides into video is a natural fit because a PowerPoint already contains the two things a video needs: visuals (each slide) and a rough structure (the slide order). Synthesia just adds the missing third ingredient, a presenter with a voice, and stitches them together.
Mechanically, when you import a deck, Synthesia maps one slide to one scene. Your slide becomes the background or on-screen visual for that scene, and you attach an avatar and a script to narrate it. Because the platform's whole model is 'video generated from text plus visuals,' a slide deck slots right in, it's essentially a pre-made set of visual backgrounds.
The AI Video Assistant can go further and draft narration for you by reading each slide's content, so you're not starting from a blank script. You then edit that text, choose a voice and language, and generate. This is why the workflow feels less like video editing and more like adding a voice track to slides you already have.
The practical payoff is the same as Synthesia's core value: your deck becomes a living video. Update a slide or a sentence, re-render, and the narrated video updates too, no re-recording. And because you can switch languages, one PowerPoint can become the same narrated video in many languages. The main caveat: complex slide animations and transitions may not carry over perfectly, so you sometimes rebuild fancy effects inside Synthesia rather than importing them intact.
An example that makes it click
Imagine you already have a stack of poster boards for a presentation (your PowerPoint slides). What you're missing is the person standing next to them explaining each one. Synthesia hands you that presenter: you feed in the poster boards, and for each board it places a narrator beside it who reads a script you provide, or one the AI drafts from the board's text.
Flip to the next board, next scene, new narration. When you fix a typo on board three, the narrator just re-reads that line, no need to re-record the whole talk. That's how a static deck becomes a narrated video.
How to do it
- In Synthesia, choose to create a video from a file and upload your PowerPoint or PDF.
- Let Synthesia convert each slide into its own scene.
- Use the AI Video Assistant to draft narration from your slides, or write the script yourself.
- Add an AI avatar and pick a voice and language for the narration.
- Review each scene, adjust text, layout, and timing as needed.
- Click Generate to render the narrated video, then edit and re-render anytime to update it.

Can Synthesia turn a PowerPoint into a video? Yes, and it's one of its easiest workflows. Here's why it fits so naturally: a PowerPoint already has the two things a video needs, visuals in each slide, and a structure in the slide order. Synthesia just adds the missing piece, a presenter with a voice. When you import your deck, it turns each slide into its own scene, using the slide as the on-screen visual, and you attach an avatar and a script to narrate it. Better yet, the AI Video Assistant can read your slides and draft the narration for you, so you're not staring at a blank script. You edit that text, pick a voice and language, and generate. The payoff: your deck becomes a living video. Change a slide or a sentence, re-render, and the narration updates, no re-recording. One caveat: fancy slide animations and transitions may not import perfectly, so you sometimes rebuild those effects inside Synthesia.
What authoritative sources say
People also ask
Does each PowerPoint slide become a separate scene?
Yes. When you import a deck, Synthesia maps one slide to one scene, using the slide as the visual, and you add an avatar and narration to each.
Do I have to write the narration myself?
No. The AI Video Assistant can draft a script from your slide content. You then edit that text, choose a voice, and generate the video.
Will my slide animations carry over?
Not always. Complex animations and transitions may not import cleanly, so you may need to rebuild those effects inside Synthesia.
Can I make the slide video in another language?
Yes. After importing, you can pick from 160+ languages, so one PowerPoint can become the same narrated video in many languages.
