Compress a Video for Email

Fit Gmail / Outlook attachment limits

Email attachment limits are tight — Gmail caps at 25 MB and Outlook at 20 MB, and encoding overhead eats into that. This preselects a safe 20 MB target so your video actually sends. All in your browser, nothing uploaded.

Attachment-safe target

A 20 MB default clears Gmail and Outlook limits with headroom for the email's own encoding overhead.

Nothing uploaded

Your video is processed entirely on your device — it never leaves your browser and nothing is stored on a server. Watch the network tab: no upload.

Free, no watermark, no caps

No account, no watermark, no length or file-size tiers, no daily limit. The things other video sites paywall are simply free here.

How to do it

  1. 1Drop your video in — a 20 MB email-safe target is preselected.
  2. 2Trim if only part of the video matters.
  3. 3Export and attach the MP4 to your email.

FAQ

What's the maximum video size for Gmail?

25 MB per message including encoding overhead — so a ~20 MB file is the safe practical target, which is what this preselects.

The video is long — will 20 MB look bad?

Long videos at small sizes trade quality. Trim to the part that matters, or send a link instead for anything over a few minutes.

Is my video private?

Completely — compression runs on your device; the file never leaves your browser.
