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.
Upload limits
| What | Limit | Plan | Source |
|---|---|---|---|
| Message size Incoming and outgoing messages. With Mail Drop turned on, attachments up to 5GB are sent as a download link. | 20 MB | Free | Official source |
| Email size (text and attachments) Whole email: all text, inserted and attached files. OneDrive links do not count (linked files up to 2GB). | 25 MB | Free | Official source |
| Outgoing attachments (total) Outgoing email, total of attachments, up to 100 files. Incoming limit is 50 MB. Proton notes that encoding makes attached files a bit larger than on your device. | 25 MB | — | Official source |
| Email attachments (total) Total of all attachments in one email, personal accounts. Above the limit Gmail replaces the attachment with a Google Drive link. Work and school limits are set by the administrator. | 25 MB | Free | Official source |
| Email attachments (total) Sum of all attachments in one message, incoming and outgoing. | 25 MB | Free | Official source |
How it works
- Choose a video — or drop it on the tool. It is opened in your browser, not uploaded.
- The tool reads its length and resolution and calculates the bitrate that fits the target.
- It re-encodes the video on your device and lowers the resolution only if needed.
- If the result is over the limit, it runs another pass. Download the file that fits.
Didn’t fit? What to do
- Trim the video: a 1-minute clip at 14 MB keeps far more detail than a 5-minute one.
- Send a link instead: Gmail switches to Google Drive above 25 MB, Outlook.com links OneDrive files up to 2 GB, iCloud Mail uses Mail Drop up to 5 GB.
- Attach one video per email: limits count all attachments in a message together.
- If the email still bounces, compress to 10 MB: the recipient's mail service may have a lower limit than yours.
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.
