What is the maximum email attachment size?

Gmail and Outlook both cap attachments at roughly 25MB. Compressing your video under that lets it send normally.

What if the video still will not fit?

Use the strongest compression preset, lower the resolution, or trim the clip. Shorter, lower-resolution video reaches very small sizes.

How to compress a video to send by email

You attach a video, hit send, and get the dreaded file too large error. Email providers cap attachments, so the fix is to compress the video below the limit before you send it.

Know the email size limits

Gmail and Outlook both cap attachments at about 25MB. Anything larger is rejected or pushed into a cloud link. Getting under roughly 25MB lets the video send as a normal attachment.

How to get under the limit

Re-encode the video with stronger compression (a higher CRF).
Lower the resolution, for example from 4K or 1080p down to 720p.
Trim the clip to only the part you need.

You do not need perfect quality

A video sent by email is usually watched once, on a phone or laptop. A strong compression preset keeps it perfectly watchable while making it small enough to attach.

Compress it without uploading

CompressEasy Desktop shrinks the video on your computer, so you avoid uploading a private clip just to share it. Pick the Maximum preset for the smallest size, then attach the result and send.
