About Video Tools
Our free browser-based Video Tools let you convert, compress, trim, and manipulate video files without uploading anything to a server. Everything runs 100% client-side in your browser using modern Web APIs like MediaRecorder, Canvas, AudioContext, and Web Workers.
Video Formats & Browser Compatibility
| Format | Chrome | Firefox | Safari | Edge |
|---|---|---|---|---|
| MP4 (H.264) | Play & Record | Play only | Play only | Play & Record |
| WEBM (VP8/VP9) | Full support | Full support | Limited | Full support |
| MOV | May work | Limited | Full support | May work |
| AVI / MKV | Limited | Limited | No | Limited |
Tips for Best Results
- Use Chrome or Edge for the best experience. These browsers have the widest MediaRecorder codec support.
- WEBM is the default output because MediaRecorder natively supports VP8/VP9 encoding in most browsers.
- Keep videos under 500MB for smooth browser-based processing. Very large files may slow your browser.
- GIF files can be large — use lower FPS and smaller width to keep file sizes manageable.
- Audio extraction outputs WAV format (uncompressed) for maximum compatibility.
- All processing is private — your video never leaves your device. Nothing is uploaded to any server.
How It Works
These tools use the browser's built-in capabilities. Video conversion and compression use the MediaRecorder API to re-encode video from a canvas stream. Trimming seeks to a start point and records until the end point. The GIF maker extracts individual frames via canvas and assembles them using the gif.js library. Audio extraction uses the Web Audio API (AudioContext) to decode and re-encode the audio track. Screenshots simply capture the current video frame to a canvas element.
Understanding Video Compression
Video compression reduces file size by lowering the bitrate (bits per second used to encode video). Lower bitrate means smaller files but reduced visual quality. The "Medium" preset is usually the best balance for sharing online. Use "High" quality when you need to preserve detail, and "Low" when file size is the top priority.
When to Use GIF vs Video
GIFs are ideal for short animations (under 10 seconds), memes, UI demonstrations, and social media reactions. For longer content, video formats like MP4 or WEBM are far more efficient — a 10-second GIF can easily be 10x larger than the equivalent video clip.
