Email encodes attachments as text, which makes them about 37% larger. This tool makes an MP4 of 14 MB or less, which stays under the 20 MB message limit of iCloud Mail even after encoding. Nothing is uploaded. Your file never leaves your device.

How it works

  1. Choose a video — or drop it on the tool. It is opened in your browser, not uploaded.
  2. The tool reads its length and resolution and calculates the bitrate that fits the target.
  3. It re-encodes the video on your device and lowers the resolution only if needed.
  4. If the result is over the limit, it runs another pass. Download the file that fits.

Frequently asked questions

What is the maximum video size for email?

iCloud Mail: 20 MB per message. Outlook.com: 25 MB for the whole email, text included. Proton Mail: 25 MB of attachments outgoing. Gmail and Yahoo Mail: 25 MB of attached files.

Why 14 MB and not 20 or 25 MB?

Email sends attachments as base64 text: every 3 bytes become 4 characters, plus line breaks, about 37% more. A 14 MB file still fits under a 20 MB limit once encoded, with room left for the text. Proton notes this effect too: encoding makes attached files a bit larger.

Can I email a long video?

Only at low quality: 14 MB holds a few minutes at most in watchable quality. For longer videos, share a cloud link instead.
