Free Video Compressor - Reduce Video File Size Online
What is a Video Compressor?
A video compressor is an online tool that reduces the file size of video files while maintaining acceptable video quality. Our free video compressor uses advanced compression algorithms to shrink video files, making them easier to share, upload, and store. The tool runs entirely in your browser with no software installation required, ensuring your videos remain private and secure.
Key Features of Our Video Compressor
Free to use with no file size limits
Compress videos up to 90% smaller
Support for all major formats: MP4, AVI, MOV, WebM, MKV, FLV
Multiple compression levels: Low, Medium, High
Adjust video resolution to reduce file size
Control video bitrate for custom compression
Preserve video quality with smart compression
No watermarks added to compressed videos
100% privacy - all processing in your browser
Fast compression using WebAssembly
How to Compress a Video
Click "Upload Video" to select your video file
Choose compression level (Low, Medium, or High)
Optionally adjust resolution to reduce size further
Set custom bitrate if you want precise control
Click "Compress Video" to start processing
Wait for compression to complete (time varies by file size)
Preview the compressed video to check quality
Download your compressed video file
Why Compress Videos?
Faster uploads to social media and cloud storage
Easier sharing via email and messaging apps
Save storage space on your devices
Reduce bandwidth usage for streaming
Speed up website loading times
Meet platform file size requirements
Improve playback on slower connections
Archive more videos in the same storage space
Compression Levels Explained
Low Compression: Minimal size reduction, highest quality (10-30% smaller)
Medium Compression: Balanced size and quality (30-60% smaller)
High Compression: Maximum size reduction, acceptable quality (60-90% smaller)
Custom: Full control over resolution and bitrate settings
Tips for Best Results
Start with medium compression to balance size and quality
Reduce resolution if file size is more important than quality
Use high compression for videos that don't need perfect quality
Keep original resolution for important or professional videos
Test different settings for optimal results
Consider your intended use case when choosing compression level
Higher bitrates preserve quality but increase file size
Modern codecs like H.265 provide better compression than H.264
Technical Specifications
Input formats: MP4, AVI, MOV, WebM, MKV, FLV, M4V, 3GP
Output format: MP4 (H.264 or H.265 codec)
Resolution options: Original, 1080p, 720p, 480p, 360p
Bitrate range: 500 kbps to 10000 kbps
Audio: Compressed to AAC at 128 kbps
Processing: Client-side using FFmpeg WebAssembly
No server upload required
Privacy and Security
Your video privacy is guaranteed. All video compression happens entirely within your web browser using WebAssembly technology. Your video files are never uploaded to any server - they remain on your device throughout the entire compression process. We cannot see, access, or store your videos. Once you close the browser, all data is automatically cleared from memory.
Our free online video compressor makes it easy to reduce video file sizes without sacrificing too much quality. Whether you need to compress videos for email, social media, or storage optimization, our tool provides the flexibility and power you need while keeping your files completely private.
