Compression Quality
Reduce video file size using H.264 compression with quality presets. Works entirely in your browser.
Upload your video, choose a quality preset, and click Compress. FFmpeg re-encodes with H.264 using the selected CRF value.
Upload your video
Drop an MP4, MKV, MOV, AVI, or WebM file onto the upload area. The file is processed locally using FFmpeg WebAssembly.
Choose compression preset
Select a quality preset: Maximum (smallest file), Balanced (good quality/size ratio), or Minimum (near-original quality).
Set resolution (optional)
Optionally reduce the output resolution (e.g. 1080p → 720p) for even smaller file sizes.
Compress
Click "Compress Video". FFmpeg re-encodes the video in your browser — this may take a minute for large files.
Download
Once complete, download the compressed video. The original file is never modified.
Email Attachments
Shrink videos to fit under email attachment size limits without switching to a file-sharing service.
Mobile Storage
Compress large phone recordings to free up storage space without deleting the video entirely.
Website Videos
Reduce background or hero video file sizes so web pages load faster for visitors.
Social Media Uploads

E-Learning Content

100% Private
