Video Compressor
Compress your video files to reduce file size while maintaining good visual quality. Perfect for sharing videos online or saving storage space. Supports MP4, WEBM, and MOV input formats.
How to Use This Tool
- Upload a video file using the file picker or drag and drop.
- Adjust the quality setting (CRF): lower values = higher quality but larger file (18-35 range).
- Choose an encoding speed preset: faster = quicker but less compression, slower = more compression.
- Optionally set a target file size or maximum width.
- Click 'Compress Video' and wait for processing (large files may take a while).
- Download the compressed video when ready.
How It Works
Video compression uses the libx264 codec with constant rate factor (CRF) encoding, running entirely in your browser via WebAssembly. The CRF value determines the quality-size tradeoff: 18 is visually lossless, 23 is the default (good balance), and 35 is heavy compression. The encoding preset controls the speed-compression tradeoff.
