How do I send a video that’s too big for email?

Gmail and Outlook reject attachments over 25 MB. The fastest fix: compress the video to just under 25 MB — the tool below reads your clip’s length, computes the exact bitrate that fits, and re-encodes it in your browser without uploading anything. Trimming the clip or sharing a cloud link are the alternatives.

  1. Compress to 25 MB. Drop the video on Compress Video to 25 MB. It calculates the bitrate your clip length allows and produces an MP4 that lands safely under the cap — no account, no upload, no watermark.
  2. Trim first if quality matters. A 25 MB budget spread over ten minutes looks rough; the same budget over one minute looks great. Cut the video to the part that matters with the video trimmer, then compress.
  3. Attach and send. Attach the compressed MP4 like any file. MP4 with H.264 plays everywhere — phones, Outlook previews, old laptops — so the recipient needs nothing special.

A phone video of a few minutes typically compresses to emailable size in under a minute of processing, at quality that is fine for viewing on any screen.

When is a link better than an attachment?

For long or high-quality footage — a full event recording, raw drone video — even perfect compression cannot make 25 MB look good. Upload to Drive, Dropbox or WeTransfer and email the link instead. The tradeoffs: recipients need to click through, links expire, and the file sits on a third-party server, which is exactly what compressing locally avoids for sensitive footage.

What are the actual size limits per provider?

Gmail and Outlook.com: 25 MB per message including encoding overhead, so treat 22-23 MB as the practical ceiling. Yahoo Mail: 25 MB. Corporate Exchange servers: commonly 10 MB, sometimes less — when mailing a company address, 10 MB is the safer target and the same tool offers it.

Frequently asked questions

Why does my 30 MB video fail even though the limit is 25 MB?

Email encodes attachments in a format (base64) that inflates them by about a third. A 20 MB file becomes ~27 MB on the wire. Aim a few megabytes under the stated cap; the compressor’s margin handles this.

Will the recipient be able to play the compressed file?

Yes. The output is MP4 with H.264 video and AAC audio — the most universally playable combination there is.

Is my video uploaded while compressing?

No. The encoder (FFmpeg compiled to WebAssembly) runs on your device. Nothing about your video touches a server — which is the entire point for private footage.
