Compress Video to 15MB
15MB is a versatile target that works for most messaging apps and email services with moderate attachment limits. It gives you 50% more space than Discord's 10MB free tier, which translates to noticeably better quality or longer clips. CompressYourVideo.com calculates the exact bitrate needed for your video's duration, so a 2-minute clip at 720p fits comfortably within 15MB with good quality. This size is ideal for sharing quick recordings in group chats, school submissions, or platforms that don't publish their exact limit but reject files over 15MB. The compressed output plays inline on virtually every device and messaging app without requiring a download.

Why compress video to 15 MB?
A 15 MB target matches WhatsApp. Unlike a blunt percentage reduction, our tool calculates the bitrate math specifically for hitting 15 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 15 MB works
When you compress a video to 15 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 strict target like 15 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 15 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
