Compress video to 25MB for email

Gmail attachments max out at 25 MB; Outlook is often 20 MB. Pick the cap, drop the file, download an MP4 you can actually attach.

Free video compressor — no file size cap, no watermark. Your browser’s memory is the only limit.

How to compress a video for email (25MB / 20MB)

Gmail’s attachment limit is 25 MB. Outlook and many workplace servers sit at 20 MB. A “send as Drive link” workaround is not always allowed — schools, lawyers, and HR still want a real attachment.

Pick Email (25MB) or Email (20MB). Shrink Clip two-pass encodes so the MP4 is under that cap. No watermark, no account, and the file never leaves this browser tab.

If a job portal or form only allows 8 MB or 10 MB, use Custom target size and type that number. Same compressor, exact budget.

How to compress a video for free

Three steps. The encoder runs on your device, so private clips never sit on a server.

1

Drop the video

MP4, MOV, WebM, AVI, or MKV. The file is read in this tab — it is never uploaded.

2

Pick a size cap

Discord 25MB, WhatsApp 16MB, email 20–25MB, X 512MB, TikTok, Instagram, or a custom MB. Bitrate is calculated, not guessed.

3

Download the MP4

Two-pass H.264 in the browser. No watermark, no account, no daily limit.

Compress video by platform

Each page pre-selects the real upload cap. Same on-device compressor — no upload, no watermark.

Compress video to 25MB for email FAQ

What size video can I email?
25 MB for Gmail and most consumer inboxes, 20 MB for Outlook and many hosts. Compress to that number here, then attach the MP4.
Why did my 25 MB video bounce?
MIME overhead and some scanners add a little. Shrink Clip aims under the cap. If it still bounces, use Email 20MB or Custom 18.
