Screen Recorder & Capture
Record your screen, window, or browser tab directly in high quality. Add microphone commentary or a webcam overlay, and capture frame screenshots with 100% local privacy.
The Screen Capture API (getDisplayMedia) requires a secure HTTPS connection. Please access this page over HTTPS.
Clicking 'Start Recording' will open the native browser prompt to choose which screen, window, or tab to share.
Ensure sensitive information such as passwords, personal chats, and private documents are not visible on the screen you share.

About Screen Recorder & Capture
Solasu's Screen Recorder & Capture is a free, browser-native web utility that lets you capture high-definition screencasts without installing standalone applications or browser extensions.
You can freely select your entire desktop screen, an individual application window, or a specific browser tab. It seamlessly supports optional microphone narration and webcam picture-in-picture overlay.
All recorded media is processed purely within your browser's local memory—zero video bytes or audio packets are ever transmitted to Solasu servers. After recording, you can review the video in an interactive preview player and extract full-resolution screenshots (PNG/JPEG) from any frame.
Flexible Screen, Window, and Tab Capture with Intuitive Controls
Built on the standard Web Screen Capture API (getDisplayMedia), Solasu lets you securely choose whether to capture your full desktop, a particular software window, or a browser tab using the native operating system prompt.
A customizable countdown timer (3s, 5s, or 10s) gives you time to switch windows before recording begins. During capture, you can monitor elapsed time, pause and resume recording, and toggle microphone or camera mutes on the fly.
Webcam Picture-in-Picture Overlay and Clean Audio Mixing
Create engaging software tutorials, product walkthroughs, and presentations by enabling the webcam overlay. Choose the corner position (top-left, top-right, bottom-left, bottom-right), size, and shape (circle, rounded rectangle, or sharp rectangle).
When narrating, verify your microphone input before starting using the real-time volume level meter. Compatible browsers can also capture system or tab audio, cleanly mixed with your voice via the Web Audio API.
Automated Playback Validation and Full-Resolution Frame Screenshots
When recording stops, Solasu automatically checks that the generated video blob can be decoded and played smoothly by your browser's video engine, preventing corrupted or incomplete downloads.
Use the timeline scrubber and frame stepping buttons (±0.1s and ±1s) to pinpoint the exact frame you want, then export it as a pristine PNG or quality-adjusted JPEG matching the video's native resolution (videoWidth × videoHeight).
100% Client-Side Privacy, No Watermarks, and No Accounts
Your screen contents, camera feed, and microphone audio remain strictly on your device. Video binary data is never written to persistent local storage (such as localStorage or IndexedDB), making it safe for shared computers.
There are no forced watermarks, advertisements, or time limits imposed on your recordings. To prevent accidental data exposure, we remind you to review open tabs for passwords or confidential conversations before starting.
Frequently Asked Questions
Can I record my screen using this tool?
Yes. You can record your entire computer display, an individual application window, or a specific browser tab in high definition.
Can I record only a specific browser tab?
Yes. After clicking 'Start Recording', select the 'Chrome Tab' or 'Browser Tab' option in the browser's sharing prompt to isolate capture to that single tab.
Can I record a specific software window?
Yes. Select the 'Window' category in the native browser prompt to record an application such as a slide deck, code editor, or document window without capturing background desktop elements.
Can I record my entire desktop screen?
Yes. Select 'Entire Screen' to record everything shown on your monitor. If you have multiple monitors connected, you can pick which display to record.
Can I record voice commentary with a microphone?
Yes. Enable the 'Include Microphone Audio' option to record your voice alongside the video. An interactive level meter helps you verify that your microphone is receiving sound before you begin.
Can I overlay my webcam video on the recording?
Yes. Check 'Enable Webcam Overlay' to display your camera feed in a picture-in-picture window at any of the four corners, with custom shapes (circle, rounded, or rectangle).
Can I capture system or tab audio?
Yes. Check the 'Share audio' box in the browser's permission prompt. Audio availability depends on your operating system, browser, and whether you are sharing a tab, window, or full screen.
Can I pause and resume during recording?
Yes. Click the 'Pause' button to temporarily halt capture, and click 'Resume' to continue. You can also press the Spacebar shortcut to toggle pause and resume.
Is there a maximum recording duration?
Solasu does not enforce arbitrary time limits. However, because video data is held in your browser's system memory (RAM), recording duration depends on your device's available memory.
Where are recorded videos saved?
When you click 'Download Recording', the video file is saved directly to your computer's default downloads directory.
Are recorded videos uploaded to any server?
No. All media streaming, compositing, encoding, and downloading take place strictly within your local browser. Zero bytes are uploaded to Solasu or third-party servers.
Will the tool access my camera or microphone automatically?
No. Camera and microphone options are turned off by default. The browser will only prompt for permission if you explicitly turn them on before starting.
Can I cancel permission requests before recording?
Yes. You can dismiss or deny any browser permission prompt. If you decline camera or microphone access, the tool gracefully falls back to screen-only recording.
Can I preview the video before downloading it?
Yes. Once you stop recording, an interactive video preview immediately loads so you can review the footage, adjust the playback position, and inspect technical metadata.
Can I capture screenshots from the recording?
Yes. Pause or scrub the video to any frame and click 'Capture Frame' to extract that instant as a high-resolution still image.
Can I save screenshots in PNG format?
Yes. Screenshots can be saved as lossless PNG files (default) or compressed JPEG files with adjustable quality.
Can I export recordings in MP4 format?
Most browsers generate standard WebM files (VP9/VP8 with Opus audio). Browsers supporting MP4 MediaRecorder output (such as modern Safari) will record directly to MP4.
Does this work on mobile smartphones?
Standard mobile browsers on iOS and Android do not support the desktop Screen Capture Web API. Please use a desktop browser such as Google Chrome or Microsoft Edge on Windows, macOS, or Linux.
What happens if I stop sharing using the browser's floating bar?
The recorder automatically detects that screen sharing has concluded and finishes the recording cleanly, preserving all footage captured up to that point.
Do I need to install a browser extension?
No. Solasu uses native HTML5 Web APIs built into modern browsers. No plugins, desktop software, or extensions are needed.
Are there any watermarks or logos on the exported video?
No. Exported videos and screenshots are completely clean with no Solasu logos or watermarks.
Do I need to create an account or log in?
No. Solasu is completely free and requires no sign-up, email, or login credentials.
