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.
Gmail’s 25 MB is for the whole message. If you also attach a PDF, leave a couple of megabytes of headroom — aim closer to 23 MB of video. Outlook tenants vary; 20 MB is the public safe guess. Zip files do not shrink video. Do not zip the MP4.
Drive links are fine for archives. They are not a substitute when a school or HR form only accepts an attachment. Compress here, attach the MP4, send a test to yourself if the recipient is high-stakes.
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 20MB, 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.
