PPT/PDF to video

Step 1: Go to PDF to Video

Step 2: Choose your starting point

You’ll see two options:

Upload a presentation — use this if you already have a PowerPoint or PDF file ready
Generate a new presentation — use this if you don’t have a file or your existing deck needs a visual refresh

If uploading an existing file, follow steps 3–4. If generating a new presentation, skip to step 5.

Step 3: Upload your file

Select Upload a Presentation and choose your file. Keep the following in mind:

Maximum file size is 50MB. If your file exceeds this, you will see an error asking you to reduce it
Speaker notes as script and importing slide content as editable elements are only available with PPT or PPTX files, not PDF

Choose your avatar upfront. It will appear as a circular overlay in your scenes. You can also replace your file from this screen.

Step 4: Configure presentation and script settings

Choose your presentation and script settings, then click Create Video to move into editing.

Step 5: Generate a new presentation

Select Generate a Presentation. You can either:

Describe your presentation using a text prompt
Upload a document (PDF or DOCX only)

For best results, be specific in your prompt. Include:

What the presentation covers
Who it's for
The tone you want
How detailed it needs to be
What outcome you want viewers to walk away with

Use the example prompts on screen for inspiration.

Step 6: Select your avatar

After clicking Continue, select your avatar. It will appear as a circular overlay in the bottom right corner of every scene. You can go back and swap your avatar or refine your prompt at any time.

Step 7: Configure generation settings

Before generating, adjust the following controls to shape your presentation:

Text usage — choose how text from your file is handled: Generate, Condense, or Preserve
Images — decide whether to keep existing images or generate new ones
Slide count — choose how many slides HeyGen should create
AI script — turn on Generate Script with AI to automatically create narration
Text density — control how much text appears on each slide
Audience — tailor the presentation for a specific group
Tone — set the overall tone and delivery style
Language — choose the output language

When you're happy with it, click Continue. HeyGen will take a few minutes to generate your presentation.

Step 8: Open in AI Studio

When generation is complete, click Edit in AI Studio.

Step 9: Refine your slides

In AI Studio, customise each slide before exporting:

Move or resize text, images, shapes or graphics
Replace backgrounds, edit titles, and adjust formatting
Swap image backgrounds for a different one if you need to

Note: full slide editing is only available if you used an editable template.

Step 10: Edit your script

Each slide has its own script segment. Script Segment 1 corresponds to Slide 1, Segment 2 to Slide 2, and so on. For each segment you can:

Rewrite the narration
Adjust pacing or fix tone
Add pauses
Upload or record your own audio
Change the voice completely

Step 11: Adjust your avatar

At any point you can:

Switch to a custom or public avatar
Switch avatars mid-project
Adjust avatar placement to suit your layout

Step 12: Export your video

When you’re happy with your slides, script, and avatar, export your video. Your presentation is now a professional video, ready to deliver your message with impact.
