The Best Free Screen Recorder with No Watermark (Unlimited Time)
The Problem with Free Recorders
Most "free" screen recorders come with a catch. They slap a giant watermark across your video, making it unusable for professional presentations or YouTube.
Others, like the free tier of Loom, limit you to just 5 minutes of recording time. And almost all of them require you to install heavy software that slows down your computer.
The Solution: KNothing Screen Recorder
We built the KNothing Screen Recorder to be different. It uses the native browser API (getDisplayMedia) to capture your screen directly.
- Zero Bloat: Just open the URL and click Record. No installation needed.
- Privacy: Your video is processed in your browser's memory. It is never uploaded to the cloud.
Key Features
- ✅ No Watermark: Get a clean video for professional use, completely free.
- ✅ MP4 Support: Native MP4 recording on Chrome and Edge (with smart fallback to WebM on Safari).
- ✅ System Audio: Capture your computer's sound along with the screen.
Usage Guide
- Go to Screen Recorder.
- Click Start Recording and choose the screen, window, or tab you want to capture.
- When you are done, click Stop.
- Download your HD video immediately.
