Large video files are hard to share. Here's how to compress them while keeping quality high — no software install needed.

Step-by-Step: Compress Video Online

1. Open FileCurve's Video Compressor
2. Drag and drop your video file (up to 50MB on free tier)
3. Select quality: High for minimal size reduction with best quality, Medium for balanced, or Low for maximum compression
4. Click "Compress Video" and wait for processing
5. Download your compressed video

Tip: The first time you use video tools, FileCurve downloads FFmpeg (~30MB). This only happens once — subsequent uses are instant.

High (CRF 23): Almost no visible quality loss. File size reduced 20-40%.
Medium (CRF 28): Slight quality reduction, barely noticeable. File size reduced 40-60%.
Low (CRF 35): Noticeable quality reduction. File size reduced 60-80%. Good for previews.

Some quality loss is inevitable when reducing file size. With FileCurve's "High" setting, the difference is virtually invisible to the human eye.

MP4 with H.264 codec is the most compatible format. FileCurve outputs in this format by default.

WhatsApp limits videos to 16MB. Use FileCurve's "Medium" or "Low" quality setting, or trim your video to a shorter duration first.
