Screen recording guide
A free screen recorder online for everyday work.
Screencast is a screen recorder online for people who want to explain, demonstrate, teach, report, or share something without creating an account first. You can record screen activity in the browser, include your camera when a face-to-face explanation helps, and review the complete recording before exporting it. The goal is simple: capture useful context quickly, keep control of the file, and share the result in the format that works for your audience.
Unlike tools that require a sign-in, cloud library, or upload before you can begin, this free screen recorder online starts on your device. There is no watermark added by Screencast and no account required to make a recording. Browser permissions still apply, because your browser asks you which screen, window, tab, camera, and microphone you want to share. That permission step keeps the choice in your hands.
Screen recorder online with audio
A clear recording needs clear context. When you use Screencast as a screen recorder online with audio, you can turn on your microphone for narration and select system audio when your browser and the shared source support it. This is useful for product walkthroughs, software bug reports, training clips, presentation feedback, and short how-to videos. Before you start, check the microphone and system-audio controls in the recorder. If you only need a silent visual demonstration, simply turn those options off.
After recording, the review panel plays one continuous video rather than a series of clips. You can listen back, confirm that the screen and audio match your explanation, and then export the take as WebM or MP4. WebM is ready immediately in modern browsers. MP4 conversion is performed locally and can take longer for large recordings, so Screencast shows progress while it works.
Use it as a webcam screen recorder
For a more personal walkthrough, choose Screen + camera. This webcam screen recorder places your camera over the shared display, with corner, circle, and side layouts to suit the recording. It works well when you are teaching a process, presenting a project, responding to a customer, or giving visual feedback. Choose Entire Screen in the browser picker when you intend to move between browser tabs or desktop apps. That lets the recording follow the work instead of staying limited to the Screencast tab.
Screencast prioritizes the native screen feed for whole-screen recording and uses a browser video-frame pipeline for the camera overlay when available. This avoids the common background-tab freeze caused by page animation loops. Live annotations remain available when you need them, although keeping Screencast visible during an annotated Screen + camera capture gives the most reliable overlay result.
How to record screen on Mac
To record screen on Mac, open Screencast in a current desktop browser, select Screen or Screen + camera, and choose Start recording. In the browser sharing dialog, select Entire Screen for a full desktop recording, or choose a specific window or tab for a narrower capture. Approve microphone or camera access only when you want those sources included. Once recording has started, switch to the app, tab, presentation, or workflow you want to show. Return to Screencast and choose Stop and review when you are finished.
The review panel below the recorder is where you can play the finished video, confirm the duration, check audio, and export the full file. If you want to make a shorter version after exporting, the optional VideoTrim link opens a separate free online trimming tool. If resolution needs improvement, the optional Upscaler link opens a free online upscaling tool. Both are optional suggestions, not a requirement for using Screencast.
How to record screen on Windows
To record screen on Windows, follow the same browser-based flow. Choose your recording mode, press Start recording, and select the display surface in your browser's share dialog. Pick Entire Screen when the recording needs to include several programs, browser tabs, or desktop windows. Pick a single window or tab when you only want that source in the video. With a current version of Chrome or Edge, you can record screen activity, add microphone narration, and use a webcam overlay without installing a separate desktop recorder.
When the recording ends, Screencast saves the complete take locally for review and also keeps unfinished chunks in browser storage for recovery. This is helpful during longer recordings, but browser storage is not a permanent archive. Export the completed video when it matters, and keep a copy in your normal files or backup workflow. Your browser decides the download folder, so check its download settings if you need exports saved somewhere specific.
Record screen privately, then share on your terms
Screencast is designed for a practical, local-first workflow. You record screen content in the browser, review it on the same device, and choose when to download an export. There is no required account and no automatic cloud upload. That makes it a straightforward choice for quick internal clips, support evidence, demos, lessons, or personal notes where you want to avoid another online workspace.
Whether you need a free screen recorder online, a screen recorder online with audio, or a webcam screen recorder for a walkthrough, start with the source you want to show and keep the message focused. Select Entire Screen for cross-app work, speak into the microphone if narration helps, review the full recording, and export only when it is ready. Recording should not slow down the work you are trying to explain.
Common questions
Screen recording FAQ
Open Screencast in Chrome, Firefox, or Edge and click Start recording. In the browser sharing dialog, choose Entire Screen for a full-desktop recording, or pick a specific window or tab. Grant microphone or camera access if you want audio or a webcam overlay. When finished, click Stop and review, then export as WebM or MP4 — no downloads, no account, no watermark.
Currently, mobile web browsers on iOS do not support web-based screen recording, so Screencast is optimized for use on your Mac or PC. To record your iPhone directly, you can use the built-in Screen Recording feature found in your Settings → Control Centre.
Use Screencast in Chrome or Edge for the simplest Windows recording experience without installing extra software. Just select your recording mode, click Start recording, and pick the screen or window you want to capture in the share dialog. When you are done, you can instantly download your clip as an MP4 or WebM file.
Screencast works natively on Chromebooks directly through the Chrome browser. Open the app, click Start recording, and easily capture your screen along with a webcam overlay and microphone audio. Everything is processed locally, meaning you get a fast MP4 export in one simple step.
Because mobile browsers have limited support for screen sharing, we highly recommend using Screencast on a desktop or laptop (Windows, Mac, or Chromebook) for the full recording experience. To record directly on your Android device, you can use the built-in Screen recorder tile in your Quick Settings.
Yes. Screencast supports microphone audio out of the box — enable the Microphone toggle before you start and grant your browser permission when prompted. To also capture sounds playing through your computer (music, video playback, alerts), enable the System audio toggle as well. Both tracks are mixed together in the final export. You can use microphone only, system audio only, or both at once.
Enabling System audio in Screencast captures your computer's full audio output — tab audio, app sounds, and music. In Chrome and Edge you will also see a Share system audio checkbox in the browser sharing dialog; make sure it is checked. On macOS, system audio capture works through the browser's built-in permission with no extra driver required. Tab audio is included automatically when you share an Entire Screen or a specific Browser tab.
No. Screencast is a local-first recorder — your video is captured and stored entirely in your browser on your own device. Nothing is uploaded to a server unless you choose to share or export it yourself. There is no account required and no automatic cloud sync. When you export, the file is downloaded directly to your computer, making it a safe choice for sensitive content like internal meetings, support tickets, or confidential demos.
After stopping, click Stop and review to open the playback panel. You will see two export options: Download WebM (instant, no processing) and Convert to MP4. The conversion runs entirely on your device — nothing is uploaded. MP4 is the better choice for sharing with most apps, email clients, and social platforms. WebM is ideal when you want the fastest possible save.
Screencast is a strong choice — it runs entirely in the browser with no sign-up, no watermark, and no automatic cloud upload. Record screen only, camera only, or screen and camera together with audio narration. After recording, review locally and export as WebM instantly or convert to MP4 on your device. Other free options include OBS Studio (desktop, more complex), ShareX (Windows), and the built-in tools on macOS (Shift + Command + 5) and iOS (Control Centre).
