PPT to Video Converter – Turn PPT into MP4 Free Online

Why use this PPT to video converter

Free with no asterisk. No account, no email, no trial countdown, no watermark in the corner, and no cap on how many MP4s you make. Nothing is held back behind a sign-up — you land on the page, drop the file, and the conversion starts.

One setting instead of twenty. A typical file-conversion site asks you for a codec, a bitrate, a frame rate, a resolution and an aspect ratio before it will touch your deck. This PPT to MP4 converter asks for one number: how many seconds each slide stays on screen. Everything else is decided for you.

You know the video length before you convert. The tool counts your slides as soon as the file is read, so the finished duration is arithmetic, not a surprise — see the formula below.

It runs in the browser, on whatever you have. Windows, macOS, ChromeOS, iPhone, Android. The rendering happens on our servers, so the locked-down work laptop with no install rights and the phone in your pocket both work the same way. No Office licence anywhere in the chain — which is the practical reason most people convert PowerPoint to video in a browser rather than on the desktop.

Your slides are rendered, not rebuilt. Fonts, colours, charts, tables, logos and spacing come through as laid out in the deck, in the order you set. Nothing is redesigned, re-themed or “improved” on the way through.

Your files stay yours. One file at a time, up to 100 MB, over an encrypted connection, deleted from our servers. We do not open your slides, reuse them, or share them.

How to convert PPT to video in 3 steps

1. Upload your presentation. Drag the deck onto the box or click to browse. This PPT to video converter takes both .ppt and .pptx, so you can convert PPTX to MP4 or an older .ppt exactly the same way. One file per conversion, 100 MB maximum — heavier deck? Run it through the PPT Compressor first and come back.

2. Set the seconds per slide. The one decision on this page. The slider defaults to 5 seconds; leave it there and the deck plays at a normal reading pace, or see the table below to pick deliberately.

3. Convert, wait, download. Press Convert to Video and the deck is rendered on our servers, slide by slide. This is not instant — a short deck is done in well under a minute, and a long or image-heavy one takes several minutes. Keep the tab open while it works; the conversion runs server-side, so nothing depends on your machine staying fast, but closing the page ends the job.

When it finishes, the page tells you the length of the finished MP4 and gives you two buttons: Download video and Convert another. The download is direct and ungated — no email wall, no “check your inbox”, no watermarked preview version. The file comes down named after your deck, so a Q3-review.pptx becomes Q3-review_video.mp4: you can turn your presentation into a video and hand it over without renaming anything.

Set the seconds per slide

Every slide gets the same screen time, from 1 to 30 seconds. That single number decides how long the finished MP4 video runs, and you can work it out before converting anything:

slides × seconds per slide = video length A 24-slide deck at 5 seconds is a 2-minute MP4. The same deck at 10 seconds runs 4 minutes.

The 5-second default is not arbitrary — it is the same value PowerPoint fills in when you export a deck with no recorded timings, so a video made here runs at the pace people already expect.

What the video is for	Seconds per slide	Why
A short clip for a feed	2–3	only the headline lands
Sending a deck instead of a .pptx	5	same rhythm as a desktop export
Text-heavy or data slides	8–12	the viewer has no “next” button
A training or course module	10–15	module length is known in advance
A screen that loops	6–10	delete hidden slides first

What carries over into the video, and what doesn’t

When you convert PowerPoint to video, everything painted onto the slide comes through: fonts, colours, logos, photos, icons, charts, tables, SmartArt and the spacing you set.

What does not come through is anything that waits for a person, and anything that makes a sound:

Does not carry over	What happens instead
Entrance, exit and build animations	the slide shows its final state
Morph and slide transitions	slides cut straight from one to the next
Hyperlinks, buttons, hover effects	rendered as static artwork
Embedded audio and video clips	not replayed; the still frame is used
Recorded narration and slide timings	stripped on upload — see below
Speaker notes	stay in the deck; they are notes for the presenter

The result is closer to a film strip than to a recording of you presenting: clean, predictable, identical on every screen.

If you recorded narration in PowerPoint, do not use this tool. A recording lives inside the .pptx and is removed the moment the file is uploaded, along with the per-slide timings it was synced to. Use PowerPoint’s own export to video with Use Recorded Timings and Narrations selected, and you keep both.

Two things to fix before you convert, not after:

• A slide that reveals four bullets one at a time will show all four at once. If a slide’s punchline depends on a click, split it in two.
• Check the slide with the smallest type. Text that sits comfortably on a laptop in PowerPoint gets read on a phone-sized video player at arm’s length. If you squint at 8-point chart labels in the deck, they will not survive the trip.

If your file won’t convert

It is over 100 MB. The most common cause by a distance, and it is almost always embedded media — a few 4K clips, or a deck where every slide carries a full-resolution photograph. Run it through the PPT Compressor and convert PPT to MP4 again; compression works on the images inside the file, so layout, fonts and slide order come back untouched.

It is password-protected. An encrypted deck cannot be read until someone types the password in PowerPoint. Open it, then File → Save As a copy without the protection and upload that. A deck merely marked as final converts normally.

The render hit the time ceiling. Very long decks exceed the processing window. Delete hidden and duplicate slides — they cost render time and lengthen the video for nothing — or split the deck and convert each half; two MP4s play back-to-back as well as one.

The file isn’t really a .pptx. Renaming a .pps, .odp or .key changes the extension, not the contents. Open it in PowerPoint, Save As → PowerPoint Presentation (.pptx), then convert PPT to video again. Same for a deck interrupted mid-download.

PowerPoint’s own export vs. this PPT to MP4 converter

PowerPoint exports video on its own, and there are two cases where it is the better choice: you recorded narration and timings you want to keep, or the deck must never leave the laptop. For everything else — a colleague’s file, a deck you need as a video in five minutes, a machine with no Office licence — the browser route is faster and costs nothing.

How to save a PowerPoint as a video on the desktop

1. File → Export → Create a Video (on newer builds, Recording → Export to Video).
2. Pick the quality: Ultra HD (4K), Full HD (1080p), HD (720p) or Standard (480p).
3. If you never recorded timings, leave Don’t Use Recorded Timings and Narrations selected and set Seconds spent on each slide — PowerPoint defaults to 5.
4. Create Video → MPEG-4 Video under Save as type → save.

Microsoft warns the render can run from minutes to hours on a long deck, and it occupies PowerPoint the whole time.
