Compress any video file right in your browser. No upload to any server — your files stay private on your device.
Compress video files instantly — no upload to any server, no watermarks, no file size limits. Drop your video, choose a compression level, and download a smaller file in seconds. Perfect for Discord's 25MB limit, email attachments, or faster web uploads. Unlike online tools that upload your files to their servers, this compressor uses FFmpeg WebAssembly to process everything directly in your browser. Your videos never leave your device — completely private and secure.
Drop or select your video file, pick a compression level (Light, Medium, Heavy, or Discord 25MB), and click Compress. The smaller file downloads instantly. No account or signup required. Works with MP4, MOV, WebM, AVI, MKV, and most other video formats.
Yes. Unlike most online compressors such as Clideo, Kapwing, or HandBrake Online, this tool never uploads your video to any server. The compression runs entirely in your browser using FFmpeg WebAssembly — a real video processing engine compiled to run locally. Your files never leave your device, making it safe for personal, business, or confidential videos.
No hard limit. Since processing happens in your browser, the limit depends on your device's available memory. Most modern computers and phones handle videos up to 500MB without issues. For very large files (1GB+), your browser may slow down during compression. The output is always MP4 for maximum compatibility.
It depends on the compression level and the original video. Light compression typically reduces file size by 30-50% with minimal visible quality loss — great for keeping high quality. Medium reduces by 50-70% with slight quality reduction. Heavy reduces by 70-90% and is ideal when file size matters more than quality. The Discord preset calculates the exact bitrate needed to fit under 25MB.
Yes. Use the Discord (25MB) preset to automatically target Discord's free upload limit. The tool calculates the optimal video bitrate based on your video's duration to keep the output under 25MB. For very long videos (over 10 minutes), the quality will be lower to meet the size target — consider trimming first with our Video Trimmer tool.
