Video Compressor

About Video Compressor

Easily reduce the file size of your videos with our Free Online Video Compressor. This tool runs entirely in your web browser using FFmpeg.wasm, meaning your video files are processed directly on your device and never uploaded to any server, ensuring your privacy.

Upload your video, choose the desired compression quality using the slider (lower values mean higher quality and larger file size), and click 'Compress Video'. You can preview the original and compressed videos side-by-side and see how much the file size was reduced before downloading.

Features:

• Secure & Private: Compression happens in your browser using FFmpeg.wasm. No files are uploaded.
• Adjustable Quality: Control the trade-off between file size and visual quality using the Constant Rate Factor (CRF) slider.
• Wide Format Support: Handles common video formats like MP4, WEBM, MOV, AVI (browser/FFmpeg dependent).
• Audio Preservation: Keeps the original audio track intact by default.
• Dual Preview: Compare the original video with the compressed result.
• Size Reduction Info: Clearly shows the original size, compressed size, and the percentage saved.
• Easy Download: Download the compressed video directly (output as MP4).
• Progress Tracking: Monitor the compression process with real-time feedback.
• Free to Use: No limits or watermarks.

How to Use:

1. Load Engine: Wait for the video processing engine (FFmpeg) to load (progress bar shown).
2. Upload Video: Drag and drop your video file or click "Select Video".
3. Preview Original: Your uploaded video will appear in the "Original Video" preview. File details are shown below it.
4. Choose Quality: Adjust the "Compression Quality (CRF)" slider. Lower values (e.g., 18) mean higher quality and less compression. Higher values (e.g., 28) mean lower quality and more compression. A value around 23 is often a good balance.
5. Compress: Click the "Compress Video" button.
6. Wait & Preview: Watch the progress bar. Once complete, the compressed video will appear in the "Compressed Video Preview" player, along with file size details. Errors will be shown in the status area.
7. Download: Click the "Download Compressed Video" button to save the result.
8. Share (Optional): Click "Share Tool" to share the tool's link.

Note: Video compression is CPU-intensive and happens entirely in your browser. Compressing large or long videos may take significant time and use considerable system resources (CPU/Memory).
