A free screen recorder that runs entirely in your browser
Quicklyzer Screen Recorder captures your screen, webcam, microphone and computer sound without installing anything and without creating an account. Recordings are made by your browser and stay on your device — nothing is uploaded to a server. Use it for tutorials, bug reports, product demos, online lessons, gameplay clips or a quick video message.
Four ways to record
- Screen — record a single browser tab, one application window or your entire screen in up to 1440p at 60 frames per second.
- Screen + Camera — add your webcam as a round or rounded bubble in any corner, in three sizes. Ideal for walkthroughs and presentations.
- Camera — record yourself with the front or back camera. This mode also works on iPhone, iPad and Android.
- Audio only — record your voice, the sound of a browser tab, or both at once, then export it as MP3.
How to record your screen
- Choose Screen or Screen + Camera and pick a quality preset and output format.
- Decide on sound: keep System / tab audio on to capture what you hear, and tick Microphone to add your voice. The volume sliders let you balance both.
- Click Start Recording (or press Alt+R). In the browser dialog select a tab, window or screen and tick Share audio.
- After the countdown, record as long as you need. Pause and resume with Alt+P, take a PNG snapshot with Alt+C, and stop with Alt+S.
- Preview the result, then download it, share it, or trim and convert it — all without leaving the page.

Features at a glance
- Floating mini controls — in Chrome, Edge and Firefox 151 or newer, a small always-on-top window keeps the timer, pause, screenshot and stop buttons visible while you work in other apps.
- Natural, unprocessed sound — echo cancellation, noise suppression and automatic gain are switched off for system audio, so music and video sound exactly as they play. Turn on Clean voice when you record with speakers or in a noisy room.
- Microphone and camera selection — choose which microphone and camera to use, including the front or back camera on phones.
- Countdown and auto-stop — start after 3, 5 or 10 seconds, and stop automatically after 1 to 60 minutes.
- Seekable WebM files — recordings are automatically fixed so video players can show their length and jump to any point.
- Trim, MP4, GIF and MP3 export — cut the start and end, convert to universally compatible MP4 (H.264), make an animated GIF, or extract the sound as MP3. Conversion runs on your device using FFmpeg compiled to WebAssembly.
- Recording library — every recording is kept in your browser's storage, so it is still there after a refresh. Play, download or delete it at any time.
- Install as an app — add the recorder to your desktop or home screen and open it in its own window with one click.
- Stays awake — the screen will not go to sleep during a long recording, and the tab title shows the running time.
Recording on a phone or tablet
Mobile browsers — Safari on iPhone and iPad, and Chrome, Firefox or Samsung Internet on Android — do not let websites capture the screen. On these devices the recorder opens in Camera mode, where you can record video and sound with the front or back camera, and Audio only mode. When you are done, tap Share to send the file straight to Photos, Files, WhatsApp or any other app.
To record your phone's screen itself, use the recorder built into the operating system: on an iPhone or iPad open Control Center and tap Screen Recording; on Android swipe down twice and tap Screen record in Quick Settings.
Which format should you choose?
WebM with VP8 gives the smoothest 60 FPS recordings and is the best choice for long or fast-moving content. VP9 makes smaller files but needs more processing power. MP4 (H.264) is offered when your browser can record it directly and plays everywhere — in video editors, on phones and on social networks. If your browser records WebM only, use Trim / Convert to turn the finished file into MP4.

Privacy by design
Capturing, encoding and converting all happen inside your browser. Your recordings are never sent to Quicklyzer or anyone else, there is no sign-up, and there are no watermarks or time limits. Because files are stored only on your device, remember to download anything you want to keep — clearing your browser's site data removes the library.
Tips for better recordings
- Close notifications and unused tabs before you start, and record a single window instead of the whole screen to keep private content out of the video.
- Wear headphones when you record your microphone together with system sound, or turn on Clean voice, to avoid echo.
- For tutorials, 1080p at 30 FPS keeps files small and text sharp; choose 60 FPS for games, animations and scrolling.
- Very long recordings use a lot of memory and storage — splitting them into parts of 30 to 60 minutes is safer.
