Compress Video Files Online - Reduce Size, Keep Quality
Reduce video file sizes without noticeable quality loss using FileMuncher's free video compressor. Whether you need to share videos via email, upload to social media with size limits, or free up storage space, our tool makes it simple. Supports MP4, WebM, MOV, and other popular video formats.
FileMuncher compresses videos entirely in your browser using FFmpeg compiled to WebAssembly. Your video files are never uploaded to any server, making this ideal for compressing personal videos, work presentations, or any content you want to keep private. The compression uses efficient codecs to significantly reduce file size while preserving visual quality.
Adjust the quality settings to control the compression ratio. Choose higher quality for videos where detail matters, or maximum compression when file size is the priority. The tool shows you the estimated output size before processing. Works on desktop and laptop browsers; video compression requires more processing power than other tools.

Frequently Asked Questions
What video formats does FileMuncher support?
FileMuncher supports MP4, WebM, MOV, AVI, MKV, and other common video formats. The compressed output is typically MP4, which is universally compatible with all devices and platforms.
Is my video uploaded to a server during compression?
No. Video compression happens entirely in your browser using WebAssembly (FFmpeg WASM). Your video never leaves your device, ensuring complete privacy.
How much can I reduce my video file size?
Typical compression can reduce video size by 40-70% depending on the original encoding and your quality settings. Unoptimized videos from cameras often see the largest reductions.
Will video compression affect the audio?
The audio is also compressed during the process, but at a quality level that maintains clarity for speech and music. The audio bitrate is optimized alongside the video.
Why is video compression slower than other tools?
Video compression requires significant processing power. Since it runs in your browser rather than on a powerful server, it may take longer for large files. This is the trade-off for complete privacy. Desktop browsers perform best.
