Screen Recorder
Record your screen and download the video, all without anything leaving your device.
This screen recorder captures what is on your screen and hands you back a video file, entirely within your browser. You can record a single browser tab, one application window, or your whole display, add your microphone if you want narration, and then download the finished clip as a WebM file. Nothing is uploaded; the recording is built on your device.
That local-only approach is the key difference from many web recorders. There is no account, no cloud processing, and no waiting for a file to upload and come back. The moment you stop recording, the video is ready to save straight to your computer.
It works using two standard browser features: getDisplayMedia, which asks the browser for your screen with your permission, and MediaRecorder, which assembles the captured frames into a video. Because these are built into the browser, there is nothing to install and no extension to add.
How to record your screen
- Choose whether to include your microphone for voice narration.
- Click record, then pick a tab, a window, or your entire screen to capture.
- Grant the permission your browser requests to start the capture.
- Do whatever you want to record, then click stop when you are finished.
- Download the recording as a WebM video file to your device.
What you can capture
When you start, the browser lets you choose the source: a specific browser tab, a single open application window, or your full display. Picking a single tab or window keeps everything else private and out of the frame, while the full screen is best for demos that move between apps.
You can optionally include your microphone, which is what turns a silent screen capture into a narrated tutorial. Choose mic input when you want to talk over what you are showing, and leave it off for a clean, silent recording.
How it works under the hood
The tool calls getDisplayMedia, the standard browser method that prompts you to share your screen and returns the video stream once you approve it. Your explicit permission is always required, so nothing can be captured without you choosing the source first.
That stream is then fed to MediaRecorder, the browser's built-in recording engine, which encodes the frames into a video file as you go. When you stop, the assembled file is offered to you as a download. Both pieces are native browser technology, so no software or plugin is involved.
Nothing is uploaded
The recording is created and stored on your device the whole time. There is no server receiving your screen, no cloud rendering step, and no copy of your video sitting in someone else's storage waiting for you to delete it.
That is exactly what you want when you are recording something sensitive, like a bug that shows account details or an internal dashboard. The footage never leaves your machine unless you choose to share the file yourself after downloading it.
The WebM output format
Recordings are saved as WebM, an open, widely supported video format. It plays natively in modern browsers and in most media players, and it is well suited to screen content, keeping file sizes reasonable for tutorials and demos.
If you need a different format such as MP4, record in WebM here and then convert the file afterwards. Being honest, this tool outputs WebM specifically, so factor in a conversion step if the place you are uploading to insists on another format.
Great for tutorials and bug reports
A short recording often explains something far faster than a paragraph of text. Walkthroughs, how-to guides, and product demos all land better when the viewer can watch the actual steps, and narration over the top adds the context.
Bug reports are another strong use. Capturing the exact sequence that triggers a problem gives developers something they can reproduce, and recording a window or tab means you can show the issue without exposing the rest of your desktop.
Tips for a good recording
Before you start, close notifications and any windows you do not want on camera, and decide whether to capture a single tab or the whole screen. Recording just the tab or window you need keeps the result focused and avoids accidentally sharing private content.
If you are narrating, do a quick microphone check first and speak clearly. Plan roughly what you will show so the recording stays tight, since a short, well-paced clip is far more watchable than a long, meandering one.
Honest limitations
This is a desktop-browser tool, working in browsers such as Chrome, Edge, and Firefox. Screen recording through these APIs is generally not available on mobile browsers, so plan to record from a computer.
Capturing system audio, the sound coming from your computer rather than your microphone, depends on your operating system and browser and is not guaranteed everywhere. On some setups you may need to tick a share-audio option when choosing the source, and on others only microphone audio is available.
Frequently asked questions
Is my recording uploaded to a server?
No. The video is captured and assembled entirely on your device using your browser, then offered as a download. Nothing is sent to a server, which makes it safe for recording sensitive screens.
What video format do I get?
Recordings are saved as WebM, an open format that plays in modern browsers and most media players. If you need MP4 or another format, record here and convert the file afterwards with a separate tool.
Can I record just one tab or window?
Yes. When you start, the browser lets you choose a single tab, one application window, or your whole display. Picking a tab or window keeps everything else off camera and private.
Can I record my voice at the same time?
Yes. Enable the microphone option before recording to narrate over your screen. Leave it off for a silent capture. Grant microphone permission when the browser asks so your voice is included.
Will it capture computer sound as well as my mic?
System audio capture depends on your operating system and browser and is not guaranteed everywhere. On some setups you tick a share-audio option when choosing the source; on others only microphone audio is available.
Does it work on my phone?
Screen recording through these browser APIs is a desktop feature, working in browsers like Chrome, Edge, and Firefox. It is generally unavailable on mobile browsers, so record from a computer instead.
