Free PPT to video AI converter: Slides to narrated video

PPT to video is the process of converting a PowerPoint or PDF slide deck into a narrated video with voiceover, music, and captions. Unlike PowerPoint's built-in Save-as-Video feature - which produces a silent, slide-by-slide MP4 - a PPT-to-video AI tool like Fliki writes a script from each slide, narrates it with a realistic AI voice, and adds a full video editor so you can swap visuals, layer b-roll, and adjust timing. The result is a real narrated video, not an animated slideshow.

PowerPoint's built-in Save-as-Video exports a silent slide-by-slide MP4. Fliki adds three layers automatically: a script written from each slide's content, AI narration in 2,000+ voices across 80+ languages, and a full video editor for swapping visuals, layering b-roll, and adjusting timing. The result is a real video, not an animated slideshow.

Fliki accepts .pptx, .ppt, and .pdf files up to 20 MB. The AI extracts slides, headings, body text, and speaker notes, then turns each slide into a video scene with voiceover.

Yes, indirectly. Google Slides does not export to Fliki natively, but you can export your deck as a .pptx or PDF directly from Google Slides (File > Download > Microsoft PowerPoint or PDF), then upload that file to Fliki. The full narration, voice, captions, and editor features work exactly the same as with a native PowerPoint file.

Synthesia specializes in avatar-driven training videos and is priced at enterprise tiers - best for large L&D teams that need a dedicated avatar presenter on every slide. Movavi and FlexClip are desktop or web video editors that can import slides but require manual scripting and voiceover recording. Fliki is free to start, auto-writes narration from your slide content, has 2,000+ AI voices in 80+ languages with optional voice cloning, and adds AI avatars without the enterprise price tag. If you want a narrated slide video without recording yourself and without enterprise pricing, Fliki is the fastest path.

No. Fliki runs entirely in the browser. No download, no plugin, no PowerPoint license needed. You can convert a deck on Mac, Windows, Chromebook, or tablet.

Fliki reads the slide text, headings, and any speaker notes, understands the slide's role in the deck, and writes a voiceover script that flows from one slide to the next. You can edit any line, regenerate sections, or change tone before exporting.

Yes. Upload a 30-second voice sample to clone your voice with high accuracy. Fliki then narrates every slide with your voice, in any of 30+ supported languages.

Yes. Pick a lifelike AI avatar from the library, or create your own digital twin. The avatar lip-syncs the slide narration with natural gestures. Useful for training, sales walkthroughs, and explainer videos where a presenter adds trust.

Yes. 80+ languages, 100+ dialects, 2,000+ neural voices. Generate the same deck in multiple languages with one click. Voiceover, captions, and on-screen text re-render automatically. Useful for global L&D programs.

Yes. Fliki preserves your slide layout, fonts, colors, images, and on-screen text. You can also restyle slides in the editor or apply your brand kit globally before exporting.

Yes. Pick from a royalty-free music library or upload your own track. Music ducks under the voiceover automatically so narration stays intelligible. Set fade points per scene.

Typically 3 to 8 minutes end to end for a 10 to 20 slide deck, including the AI script, voiceover, captions, music, and final 1080p MP4 export. Long decks (50+ slides) take longer.

Export 1080p MP4 (or 4K on paid plans) in 16:9 (default for slides, YouTube, LMS), 1:1 (LinkedIn, Facebook), or 9:16 (TikTok, Reels, Shorts). Resize the same source across formats with one click.

Yes. The built-in timeline editor lets you trim, swap clips, regenerate slide narration, layer in stock or AI-generated b-roll, change fonts and captions, and reorder scenes. Full control without leaving Fliki.
