Screen Recorder
Choose a screen, window or tab to record locally, pause, preview and download supported video.
Recording begins only after you choose a capture source in the browser. The recording stays in this tab until you download it; Toolvore does not upload it. Close private tabs and notifications before sharing a screen, and record only content you have permission to capture.
Record a selected tab, window or screen with optional shared sound or microphone narration, then preview and download the browser's actual WebM or MP4 recording.
How to use it
- 1Choose quality, session limit and optional audio. Close private content, then press Choose screen & record.
- 2Select the source in the browser chooser. Check the reported audio tracks; pause, resume or stop as needed.
- 3Play the saved preview to verify picture and sound, then download it before leaving.
What happens to your data
Toolvore does not upload the recording. Capture starts only after your explicit action and browser permission; audio options default off. Recordings stay in page memory, with a 100 MiB retained-data ceiling and at most a 15-minute session including pauses. Desktop/browser support varies; there is no autosave.

Make a short screen demonstration or bug report and save it directly from your browser. Choose a tab, window or screen in the browser's own sharing dialog, optionally request shared audio or microphone narration, then pause, resume and stop. Review the saved video before downloading the browser-generated WebM or MP4.
The recording stays in this page's memory and is not uploaded by Toolvore. There is no account, extension, server rendering or cloud sharing link. Screen capture is primarily a desktop-browser workflow: many mobile browsers do not expose it, even though the page and controls fit small screens.
How it works
Nothing requests screen or microphone access until you press Choose screen & record. Both optional audio controls are off by default. The browser asks which source to share on every start. Close unrelated windows and hide notifications first; selecting one tab or window reduces accidental exposure compared with sharing the whole screen. Only record content you have permission to capture.
Request tab or system audio asks the browser for an audio track from the shared source. Availability depends on the browser, operating system and source. Selecting a browser tab and enabling Share audio in the chooser is often different from sharing an application window. If no shared-audio track is returned, the page clearly reports video-only or microphone-only recording. It never claims that selecting the checkbox proves sound was captured.
Include microphone requests separate microphone permission after screen selection. If it is refused, setup stops and all acquired screen tracks are released, rather than silently recording without the requested narration. When both audio sources are present, Web Audio mixes them into one audio track for MediaRecorder. There is no live speaker playback from the mixer. If microphone sharing ends mid-session, recording stops rather than quietly losing narration.
Standard quality prefers 1,280 × 720 pixels at 15 frames per second and a 2 Mbps video bitrate. High prefers 1,920 × 1,080 at 30 fps and 5 Mbps. These are preferences: the actual captured dimensions are displayed after capture starts. The browser selects a supported WebM or MP4 encoder, and the saved filename and Blob media type match the actual recording format. This page does not transcode WebM into MP4.
Choose a 5-, 10- or 15-minute session limit. The wall-clock timer includes time spent paused, preventing an indefinitely open session. Recording data is emitted in chunks, with a hard 100 MiB retained-data ceiling. If a chunk would exceed it, the session is stopped and discarded rather than offering a truncated or corrupt file. Browser delivery can be delayed and transient browser buffers can exceed the retained-data budget. The displayed received-byte count is not an exact live file-size forecast.
Stop recording, the browser's Stop sharing control, a limit or leaving the page releases capture tracks and the audio mixer. A pending chooser result is discarded if start was cancelled or the page was left. The previous preview survives a cancelled or failed start; a successfully started new recording replaces it. Download before leaving or reloading, because there is no autosave. Discard recording releases this page's preview but cannot erase a copy already downloaded.
Common use cases
- Recording a reproducible software bug with a short visual walkthrough
- Capturing a presentation tab with optional shared sound
- Making a narrated how-to clip without uploading it to a recorder service
- Saving a short screen demonstration for later review
Frequently asked questions
Can I record screen and system audio on every device?＋
No. Audio capture varies by browser, operating system and source. The checkbox requests sound; it cannot force the chooser to offer it. The page reports whether a track actually arrived. Make a short test and listen to the preview before recording a longer take.
Is my microphone on automatically?＋
No. Include microphone is off by default and requires explicit selection plus browser permission. The tool does not request camera access.
Will I get an MP4 or a WebM file?＋
The browser's supported encoder determines the format. The download extension matches the recorder's actual media type. There is no MP4 conversion step, so a WebM recording is not renamed to pretend it is MP4.
Why does it not work on my phone?＋
Many mobile browsers do not support getDisplayMedia screen capture. The page shows that limitation instead of an unusable start button. Use a supported desktop browser over HTTPS or your device's own screen recorder.
Why was a large recording discarded?＋
The page retains at most 100 MiB of encoded recording chunks. Exceeding the limit stops and discards the take because dropping arbitrary chunks can create an invalid video. Choose Standard quality and a shorter take; download each completed recording separately.
Does pausing stop screen sharing?＋
No. Pause stops MediaRecorder from adding media, but the browser's screen-sharing session remains active. Stop recording ends the sharing tracks. Paused time still counts toward the session limit.
Are recordings saved online or restored after a crash?＋
No. They remain in memory in this open page until downloaded. The tool provides no cloud upload, autosave, trimming, captions or crash recovery. Review and download each take before leaving.
