As mentioned, you can use the video editor offered by WonderFox HD Video Converter Factory Pro to easily and quickly trim unnecessary segments or split a long video into shorter clips and send them in separate emails.

Note, however, since the video is already compressed, using Zip compression typically saves only an additional 5% to 10% of space. So if your file is 100 MB, this method cannot magically shrink it to under 25 MB.

Here's how to email a large video with a YouTube link.

In addition to YouTube, you can also upload videos to Vimeo, Facebook, Twitter, etc. any video-sharing site you are familiar with, then share the video link without hassle.

Similar to sharing a video link, uploading a video to a cloud service can also help you bypass the email attachment file size limit. This can be private and secure, depending on your sharing settings. But the best thing about using a cloud service is that it won't compromise the video quality, so you can really send a video without losing quality.

The file size of a video is affected by several factors, including compression method (encoding), resolution, bit rate, frame rate, and length.

High-efficiency encodings such as HEVC, VP9, and AV1 can create smaller videos at the same level of quality compared to inefficient encodings such as MPEG-2, WMV, and MPEG-4.

Also, the higher the resolution, bit rate, and frame rate, the larger the video file size.

The easiest way to make a video less MB is to use a video MB reducer like WonderFox HD Video Converter Factory Pro. With its help, you can efficiently reduce high MB to low MB while keeping a decent video quality.

A video size reducer like HD Video Converter Factory Pro is going to greatly help you make a video less than 25MB.

When you attach a file to an email, the email client converts the binary file to MIME (Base64) format, which adds about 33% overhead to the file size. So a 24MB file on your hard drive might be ~31MB in transit, which would be over the 25MB limit. So, it's best to target the final size around 20MB for seamless sending.

Not if you do it right. For example, converting an old video into MP4 with H265 encoding or downscaling a 4K video to crisp 720p can significantly reduce file size while keeping a very clean visual quality on phone screens.

You can email videos in many formats. But for compatibility, MP4 is the best video format for emailing.
