How do I compress a video to send in an email?

Upload your video above and compress it, then attach the smaller file to your email. Our server re-encodes with H.264 to lower the bitrate, so a clip that was too large to attach comes back small enough to send — no cloud link required.

What size does a video need to be for email?

It depends on the provider: Gmail allows 25 MB, Outlook.com 20 MB, and Yahoo 25 MB — but many corporate and school mail servers enforce a stricter 10 MB limit. Compressing before you attach keeps the email deliverable everywhere. If you need a hard 10 MB, use the dedicated Compress to 10MB tool.

Will the video still look good after compressing for email?

Yes. Choose the high-quality level and a short-to-medium clip stays sharp — clear enough for the recipient to watch comfortably. Longer videos trade more quality to fit under strict limits, so trim first if you can.

Why won't my video attach to my email?

Email servers reject attachments over their size limit. A single minute of phone or camera video can easily exceed 25 MB, which is why raw clips bounce. Compressing re-encodes the video at a smaller bitrate so it fits under the cap and sends as a normal attachment.

Is it free and private?

Yes — completely free, no account required. Your video is processed on our server and deleted the moment your download starts. It's never stored or shared.

Does it work on iPhone, Android, and desktop?

Yes. It runs in any modern browser on iPhone, Android, Mac, and Windows. Compress on your device, then attach the smaller file to your email.

Why Email Rejects Big Videos

Mail servers cap attachment size to manage bandwidth and storage. Over the limit, your provider either blocks the send or swaps the file for a cloud link the recipient has to click.

Compressing the video below the cap means it attaches like any normal file and plays inline — the simplest way to actually get a video into someone's inbox.

Email Attachment Limits

What size do you need for each provider?

Pick a quality level that lands your video under the recipient's limit — the safest target is the strictest inbox it needs to reach.

Gmail — 25 MB

Gmail caps attachments at 25 MB. Larger files are automatically pushed to a Google Drive link instead of attaching — compress first to send the video directly.

Outlook — 20 MB

Outlook.com limits attachments to 20 MB, and many corporate Exchange servers enforce 10 MB. Compressing keeps your video attachable across strict business mail systems.

School & corporate — often 10 MB

University and workplace mail systems frequently cap attachments at 10 MB. For those, aim lower — or use the dedicated Compress to 10MB tool for a hard target.

How To Compress Video for Email

Step 1

Upload your video

Drag and drop the clip that's too big to email, or click to browse. MP4, MOV, WebM, AVI, and MKV all work.

Step 2

Check the estimated size

The tool estimates the compressed size before you start, so you can pick a level that lands under your email provider's limit.

Step 3

Compress on our server

Click Compress and our server re-encodes the video with H.264. Processing usually takes 1–3 minutes. Your video is deleted the moment your download starts.

Step 4
