Screen Recorder
Record your screen — a whole display, a window or a single browser tab — with optional microphone narration, then download the video. No install, no watermark, no upload. The recording is captured and saved entirely on your device.
Runs entirely in your browser — your recording is never uploaded.
- No upload Your video never leaves your device — it is processed locally.
- Works offline After the first load it runs with no internet connection.
- No size or daily limits No file caps, no paywalls — only your device memory.
- Private & safe Skip sketchy upload sites; nothing is sent to a server.
How it works
This recorder uses two capabilities your browser already has:
getDisplayMedia, which (after you choose what to share in the browser's own
prompt) provides a live video stream of your screen, and MediaRecorder, which
encodes that stream into a video file as it plays. If you enable the microphone, a second
stream from getUserMedia is mixed in with the Web Audio API so your voice and the
picture stay in sync. Everything happens locally — the frames are encoded on your device and
assembled into a WebM file held in memory until you press Stop, at which point it becomes a
downloadable file. No part of the video is sent over the network.
How to record your screen
- Optionally tick Include microphone to narrate while you record.
- Press Start recording and choose a screen, window or tab in the browser prompt.
- Do whatever you want to capture; the timer and live preview show the recording in progress.
- Press Stop & save, then click Download to keep the WebM file.
Your browser requires a click to begin and shows its own sharing dialog — that prompt is a privacy feature, so you always control exactly what is captured. You can also stop a recording from the floating "Stop sharing" bar the browser shows.
Why record in the browser instead of installing software
Desktop screen recorders are powerful but mean an install, an account, and often a watermark or a length cap on the free tier. Online recorders that upload your capture raise an obvious privacy problem: your screen frequently shows email, chats, banking or work documents, and sending that to someone else's server is exactly what you do not want. Recording in your browser keeps the footage on your own machine with nothing to install and nothing to upload. It also sidesteps the safety concerns around free file-handling sites — in March 2025 the FBI warned that some free online tools were being used to spread malware, so keeping the work local is the safer choice.
| Local (this site) | Typical cloud tool | |
|---|---|---|
| Upload required | No | Usually |
| File-size caps | None (device memory) | Common |
| Works offline | Yes, after first load | No |
| Files stay private | Yes — never sent | Sent to a server |
Common uses
Recording a software tutorial or product demo with voice-over, capturing a bug to show a developer, saving a video call or webinar for people who missed it, making a how-to for a colleague, or grabbing a clip of gameplay or a presentation. Because it runs in the browser, you can record on a managed work laptop where installing software is blocked, and the resulting file is clean and watermark-free.

Frequently asked questions
Is my screen recording uploaded anywhere?
No. The recording is captured by your browser straight into memory on your own device using the standard MediaRecorder feature, and the finished WebM file is written locally for you to download. Nothing is streamed to a server, there is no account, and when you close the tab the data is gone from memory. That is the whole point of a no-upload recorder: your screen, which may show private documents, messages or accounts, never leaves your machine.
Can I record my voice or system sound at the same time?
Yes. Tick "Include microphone" before you start and the tool will ask for mic permission, then mix your voice into the recording — useful for tutorials, walkthroughs and demos. Whether the audio playing on your computer (system or tab sound) is captured depends on your browser and the option you tick in its share dialog: Chrome and Edge can include tab or system audio when you check "Share audio", while some browsers and operating systems only allow the screen video. If a track is unavailable the tool records everything it can rather than failing.
Why does it save as WebM instead of MP4?
Browsers record to the formats their built-in encoder supports, and the near-universal one for in-browser capture is WebM (VP8 or VP9 video with Opus audio). WebM plays in Chrome, Edge, Firefox, VLC and most modern players, and it is efficient and high quality. If you specifically need an MP4 — for example to import into older editing software — record here, then convert the file with the Video Converter on this site, which also runs entirely in your browser.
Which browsers and devices can record the screen?
Screen capture works in recent desktop versions of Chrome, Edge, Firefox and Opera, and in Safari 13 and later on macOS. It requires a secure (HTTPS) page and a click to start, because the browser must show its own "choose what to share" prompt for your privacy. Most mobile browsers do not expose screen capture to web pages, so screen recording is a desktop feature; on a phone, use your operating system's built-in screen recorder instead.
Is there a time limit on the recording?
There is no fixed limit built into the tool. The practical ceiling is your device memory, because the video is held in memory until you stop and download it. Short clips of a few minutes are effortless; very long sessions of an hour or more use a lot of memory and are better split into parts. For a long capture, stop and save periodically rather than recording in one continuous take.
Does it add a watermark or cost anything?
No watermark, no sign-up and no payment. Many desktop and online screen recorders stamp a logo on free recordings, cap the length, or push you toward a subscription. This tool is free and uses only what your browser already provides, so the output is clean and yours to keep.
All recording happens on Video Tools entirely within your browser. Your screen is never uploaded to a server.
