Compress a video for PowerPoint
PowerPoint stores the whole video inside the presentation, so one phone clip can make a deck hundreds of megabytes. Shrink the clip here first, then insert the small file.

How it works
- Drop your videoMP4, MOV, WEBM or MKV, any size. It stays on your computer.
- Choose how"Smaller, same look" for a big saving without visible loss, or an exact size such as 10 MB. You see the result before you start.
- DownloadPreview the result, then save it. Exact sizes are checked before you download.
Which size to pick
- A deck you will email: most email services accept about 15 MB in total, so aim for 10 MB per clip, or less with several clips. The email page explains the limits.
- A deck you present from your own laptop or a shared drive: 25–50 MB keeps a few minutes of video sharp on a projector.
What fits in 25 MB (≈ means about; soft means visibly blurry):
| Length | With sound | No sound |
|---|---|---|
| 30 sec | 1080p | 1080p |
| 1 min | ≈850p | ≈860p |
| 2 min | ≈580p | ≈610p |
| 3 min | ≈470p | ≈500p |
| 5 min | ≈360p | ≈380p |
PowerPoint can compress too, so why here?
PowerPoint for Windows can shrink videos that are already in a deck (File → Info → Compress Media), with a few fixed quality steps. Compressing here first lets you choose the exact size, see the result before it goes into the deck, and works whichever version of PowerPoint you have.
Insert the compressed video
Download the MP4, then in PowerPoint choose Insert → Video and pick the file from your computer. MP4 is the format Microsoft recommends for videos in PowerPoint.

Why your video never leaves your computer
Online video tools upload your file to their servers, process it there, and send it back. That is slow for big videos and costs them money for every minute, so free plans cap your file size or add watermarks, and your video sits on someone else's computer.
Here your own computer does the work, inside this tab. Nothing is uploaded, so there is nothing to cap: no file size limit, no daily limit and no watermark.
Questions
Will the video still play in PowerPoint?
Yes. You get an MP4 file, which plays in PowerPoint on Windows and Mac.
Is my video uploaded?
No. It is compressed inside your browser, so confidential clips stay on your computer.
Is it really free?
Yes. Your computer does the work, so a video costs us nothing to process. No account, no watermark, no limits.
Is my video uploaded?
No. It is processed inside this browser tab and saved straight back to your computer.
Which browsers work?
Recent Chrome, Edge and Safari on a computer. Chrome and Edge are fastest on most machines. Phones work for short videos.
How long does it take?
In Chrome, a one-minute 1080p video took 13–19 seconds on the laptops we tested and about 40 seconds on a computer without a graphics chip. Safari can be slower.
Can I close the tab while it works?
Keep the tab open and in front until it finishes. Browsers slow down background tabs.
