What's the typical email attachment limit?

Many providers cap attachments around 20-25MB. If your clip is longer, consider lowering resolution or using a cloud link.

Which format sends best via email?

H.264 + AAC in MP4 balances size and compatibility across devices.

GIFs are much larger than MP4 for the same content. Converting to MP4 shrinks size and plays smoothly.

Yahoo Mail enforces a 25MB attachment cap. Drop your video, choose the right preset, and send it without hitting the bounce limit.

🔒 Secure & Private: Files auto-delete after 1 hour. No sign-up required.

Target 22-23MB to leave headroom for MIME/base64 overhead.
Stick with MP4 (H.264 + AAC) for the smallest file that still previews in webmail.
Longer than 90 seconds? Downscale to 720p or 480p so your bitrate stays realistic.
Send bigger clips via Dropbox. Yahoo automatically offers a Dropbox handoff when attachments exceed 25MB.

Enter duration to get the recommended video bitrate for a 25MB (or 22MB) Yahoo Mail attachment.

Need to send a longer training or 4K clip? Let Yahoo upload it to Dropbox and send the share link automatically.

If the recipient is on Gmail, they will receive a Dropbox link-the Gmail guide explains how Drive compares.

Why did my 24MB file bounce?

The MIME-encoded size can grow 30% over the raw file. Export closer to 22MB or use Dropbox.

Can I send multiple videos at once?

Yes, as long as the combined encoded size stays under 25MB. Otherwise Yahoo will offer Dropbox.

Does the calculator work for Gmail too?

Absolutely. Change the target to 25 or 20MB, then compare with the Gmail calculator for Drive workflows.
