About the Screen Recorder
Tezmy's Screen Recorder captures your whole screen, a single window or one browser tab straight from your browser, so there's nothing to install. Add your microphone to talk people through a tutorial, and include the tab or computer sound where your browser allows it. A timer shows the length, you can pause and resume, and when you stop, the video plays right on the page so you can check it before downloading. There's no watermark and no sign-up, and the video is made on your own computer: nothing is uploaded.

How to use the Screen Recorder
- 1Choose whether to record screen sound and your microphone.
- 2Press Start recording, then pick the screen, window or tab to share in your browser's window.
- 3Do what you want to show. Use Pause and Resume if you need a break.
- 4Press Stop (or your browser's Stop sharing button), watch the video, then Download it.
Screen, window or tab: which to share?
- Entire screen: everything you see, including notifications. Best for moving between several apps. Turn on Do Not Disturb first so private messages don't pop up.
- Window: one app only, such as PowerPoint, Excel or a code editor. Other windows stay private, even if they cover it.
- Chrome or Edge tab: just one website, and the only choice that also records that tab's sound on every system. Ideal for demos of web apps or recording an online lesson you're allowed to keep.
Making a clear tutorial or bug report
Close tabs and apps you don't need, and make text bigger (Ctrl or Command and +) so viewers can read it on a phone. Plan the steps before you start, and use Pause instead of stopping if you need to look something up. Move the mouse slowly and pause for a second after each click so people can follow.
For a bug report, start recording a few seconds before the problem, show the steps that cause it, and finish with the error on screen. A short video often explains a problem better than a long email, and a 1-minute clip is small enough to attach to most tickets.
Sound: microphone, tab audio and system audio
Your microphone is added when you tick Record my microphone; a headset gives clearer speech and avoids echo from the speakers. The screen's own sound depends on the browser: Chrome and Edge can record a tab's sound anywhere and the whole computer's sound on Windows, if you turn on the audio switch when choosing what to share. On a Mac, the whole computer's sound usually isn't offered, so share the tab instead. When both are on, they are mixed into one soundtrack.
File size and quality
The quality follows the size of what you share: a 1080p screen is recorded at about 5 Mbit/s, which keeps small text sharp, and smaller windows use less. Expect roughly 35–40 MB per minute at 1080p. To send a long recording by email or chat, trim it or make it smaller with a video compressor, or upload it to a cloud drive and share the link. A recording usually needs a voice or a script. Add commentary with the Voice Recorder, turn a written script into speech with Text to Speech, and use the Image Converter when you want a screenshot in a different format for a guide.

Frequently asked questions
Is this screen recorder really free with no watermark?
Yes. There's no sign-up, no watermark and no limit set by us. The video is made by your own browser, so we never see it and there's nothing to pay for.
Can I record my screen with sound?
Yes. Tick Record my microphone to add your voice. For the sound playing on the computer, tick Record screen sound: in Chrome and Edge you then turn on the audio switch in the sharing window (tab audio, and on Windows also system audio). Firefox and Safari can record your microphone but not the screen's own sound.
Can I record my screen on an iPhone or Android phone?
Not from a website: phone browsers don't allow it. Use the phone's built-in recorder instead: Screen Recording in Control Centre on iPhone and iPad, or Screen record in Quick Settings on most Android phones. This page shows the steps when you open it on a phone.
What format is the video, and will it play everywhere?
Newer Chrome and Edge versions and Safari save MP4, which plays on practically everything. Firefox and older Chrome save WebM, which plays in browsers, VLC and YouTube but not in every video editor. The file name shows which you got; a video converter can turn WebM into MP4.
Is my recording uploaded anywhere?
No. Recording and saving happen inside your browser. The video stays in the page until you download it, and it's gone when you close or reload the page.
Why does my Mac say the browser can't record the screen?
macOS asks for permission the first time. Open System Settings > Privacy & Security > Screen & System Audio Recording, switch on your browser, then quit and reopen the browser and try again.
How long can I record?
We don't set a limit, but the video is held in your computer's memory until you download it. A 1080p recording takes about 35–40 MB per minute, so for long sessions record in parts of 30–60 minutes.
