Email remains one of the most common ways to share files, but nearly every provider limits attachment size to 25 MB. A single minute of 1080p video can easily exceed 100 MB, making email delivery impossible without compression.

Why Are Video Files So Large?

Video files contain thousands of individual frames along with audio data. At 30 frames per second, a one-minute clip has 1,800 frames. Without compression, each frame would be several megabytes, resulting in gigabyte-sized files.

Step-by-Step: Shrink a Video for Email

1. Trim first: Remove any unnecessary footage before compressing. Shorter videos mean smaller files.
2. Lower the resolution: If the recipient will watch on a phone, 720p is more than enough.
3. Compress: Use our online compressor and select the "Small Size" preset to target the lowest file size while keeping the video watchable.
4. Check the result: Make sure the output is under 25 MB and the quality is acceptable.

Alternative: Cloud Links

If the video is still too large after compression, consider uploading it to Google Drive, Dropbox, or OneDrive and sharing a link instead. This avoids attachment limits entirely.
