Compress Video to 25MB
25MB is Gmail's attachment size limit. Files above 25MB are automatically converted to Google Drive links, which requires the recipient to click through and download separately. Compressing to 25MB keeps your video as a true inline email attachment that recipients can preview directly. CompressYourVideo.com targets 23MB (safe margin) and calculates the optimal bitrate for your video's length. A 5-minute video compresses to 720p with good quality at this size. This target also works for Yahoo Mail (25MB limit) and most webmail services. For corporate Outlook users with 20MB limits, use the 20MB target instead.

Why compress video to 25 MB?
A 25 MB target matches Gmail / Email. Unlike a blunt percentage reduction, our tool calculates the bitrate math specifically for hitting 25 MB: total budget in kilobits, minus the audio track, divided by duration. That means a 30-second clip keeps more resolution than a 10-minute clip at the same target, which is how it should be.
With CompressYourVideo.com, just select your target size, upload your video, and download the compressed version in seconds. No signup required.

How video compression to 25 MB works
When you compress a video to 25 MB, the tool analyzes your video's duration, resolution, and content complexity to calculate the optimal bitrate. The bitrate is the amount of data used per second of video. A lower bitrate means a smaller file, but also lower visual quality.
For a moderate target like 25 MB, the process involves: (1) analyzing your video's duration to calculate the maximum bitrate that fits, (2) scaling resolution down if the bitrate is too low for the original resolution (e.g., 1080p to 720p), and (3) encoding with optimized settings that prioritize visual clarity over mathematical perfection.
Default output is MP4 with H.264 video and AAC audio: the most universally compatible format, plays inline on every device, browser, and messaging app. Need MOV, MKV, or WebM instead? Switch in Advanced settings.
Tips for best results at 25 MB
- Trim first: Shorter videos get more bitrate per second, which means better quality at the same file size
- Good lighting helps: Well-lit footage compresses more efficiently than dark or grainy video
- Avoid text overlays: Small text and fine details are the first things to degrade during compression
- Keep it under 2 minutes: For targets under 25 MB, videos over 2 minutes will show noticeable quality reduction
