Compress a video for Teams
Make a video small enough to attach in a Teams chat. It never leaves your device, so it never passes through an outside service.

What do you want to do?
How do you want to edit it?
Pick as many as you like. Each one opens its own editing screen, and they are all applied in one pass at the end.
Make the file
Four promises
No upload
Your video is handled only on your own device. It is never sent anywhere, so you can safely use it with work or school videos.
Just pick
Pick Discord as the place you are sending to, and the size and the picture quality are set for you. There is nothing complicated to set up.
No watermark
Nothing is stamped onto your video, and there is no limit on how many you make.
Picture quality like the pros
We use the numbers people use in video work. If the picture quality is going to drop a lot, we tell you before you save.
How to use it
- Choose the video you want to send.
- Pick "Microsoft Teams (chat)" as the destination.
- Check "What you will get" to compare the size before and after.
- Make the file, then attach it in Teams yourself.

100MB attached to a chat message
Microsoft Teams allows files up to 100MB attached directly to a chat (official help, checked September 12, 2026).
Sharing through Files is a separate allowance and handles much larger files. For video over 100MB, put it in SharePoint or OneDrive and send the link rather than attaching it.
100MB keeps ten minutes at 720p
| Length | Left for the picture | Expect |
|---|---|---|
| 3 minutes | About 4.3Mbps | 1080p |
| 5 minutes | About 2.5Mbps | 1080p |
| 10 minutes | About 1.2Mbps | 720p |
That is enough for meeting recordings and walkthroughs, where the text on screen has to stay readable.
Before you send
- For people outside your organisation, an attached file is often easier to open than a link.
- Your organisation may have lowered the attachment limit.
- Long meetings are easier to watch when you trim to the part that matters.
Tips from the pros
- Teams has two different limits. A chat attachment can be up to 100 MB (ten files per message). A file put in the Files tab can be up to 250 GB — a completely separate allowance.
- Drag a big video into the chat box and it stops at 100 MB. Put it in the Files tab instead and share the link in chat.
- Teams does not re-compress video, so what you make here is what arrives.
Common questions
How large can a Teams chat attachment be?
Microsoft documents 100 MB per file, up to ten files per message (checked 12 September 2026).
I heard the limit was 250 GB?
That is for the Files tab, backed by SharePoint. Dragging into the chat box is capped at 100 MB.
Do meeting recordings work the same way?
No. Recordings have their own limit of four hours or 1.5 GB.
Does the quality drop?
Not on the Teams side — only by as much as you compress here. 100 MB keeps a few minutes of video looking good.
Is it safe for work videos?
Your video is processed on your own device and never sent anywhere, so it never passes through an outside server.
