Record your screen to WebM video locally.
Nextooly’s Screen Recorder (Web) allows you to capture your screen, browser tabs, or application windows directly in your browser with no installation required. Using the MediaRecorder API, the tool records high-quality WebM video and optionally mixes system audio with microphone audio for tutorials, walkthroughs, demos, meetings, coding sessions, or presentations.
Recordings never leave your device — they stay in your browser memory until you download or delete them. Pause, resume, auto-stop timers, codec options, and multi-recording management make it a powerful privacy-friendly alternative to desktop screen recorders.
Example
Input: The source text, file, or settings you want to work with.

Does this screen recorder upload my recordings anywhere?
No. All recording, processing, and video storage happen entirely in your browser using MediaRecorder. Nothing is ever uploaded to a server.
Why do I see a browser message saying 'Your screen is being shared'?
This is a built-in security indicator from Chrome/Edge/Firefox whenever screen capturing is active. It cannot be removed, but stopping the recording will close it automatically.
Can the tool record both system audio and microphone audio?
Yes. System audio is captured directly from the screen stream, and microphone audio is mixed using the Web Audio API for combined voice + system sound recordings.
Why does the microphone option sometimes fail?
Some browsers block microphone access if permission is denied, restricted, or if HTTPS is not used. The tool gracefully continues with system audio only.
What video format does this tool record in?
Recordings are saved in WebM format (video/webm) using VP8/VP9/H.264 depending on your browser’s supported codecs.
Why can’t I play WebM recordings on some devices?
Some media players or older devices lack WebM/VP9 support. Converting the file to MP4 using a separate converter solves this.
Can I pause and resume recordings?
Yes. The tool fully supports pausing and resuming recordings without creating separate video files.
Why does the recording stop automatically?
If you set a maximum duration, the recorder auto-stops when the limit is reached. The recording also stops if you press the browser’s built-in 'Stop Sharing' button.
Where are my recordings stored?
Recordings exist only in your browser’s memory and are listed under the 'Recordings' section. You can download or delete them manually.
Why does the preview switch to the recorded file after stopping?
The tool automatically shows the latest saved recording for easy reviewing or downloading.
Can the tool record specific application windows instead of the whole screen?
Yes. The browser’s native screen picker lets you choose a window, tab, or entire screen before recording begins.
Why does recording fail sometimes when selecting system audio?
Browser policies restrict system audio capture depending on OS, application source, and DRM content (e.g., Netflix cannot be recorded).
