How to Record Your Screen Online (Free)
A quick bug report for a coworker, a walkthrough of a workflow, a demo of something breaking that's hard to describe in words — here's how to record your screen without installing any software, using nothing but your browser.
Steps
- Open Stelluna's Screen Recorder at stelluna.io/screen-recorder.
- Choose whether to include audio, then click Start Recording.
- Pick what to share in your browser's own picker — your whole screen, one window, or a single tab.
- Do what you need to record, then click Stop Recording (or use your browser's own "Stop sharing" button).
- Preview and download your recording as a WEBM file.

Open Screen RecorderWhy does the recording download as WEBM, not MP4?
WEBM is the format browsers can natively record to without any extra encoding software — it's what makes recording possible with zero installs and zero uploads in the first place. WEBM plays fine in every modern browser and in most video players and editors; if you specifically need an MP4, you can run the downloaded file through Stelluna's Video Format Converter afterward.
FAQ
Is it free?
Yes — no account, no watermark, no limit on how many recordings you make.
Does my recording get uploaded anywhere?
No. Recording is handled entirely by your browser's own APIs and stays on your device — it never goes to a server.
Can I record just one browser tab instead of my whole screen?
Yes — when the browser's sharing picker opens, choose the "Chrome Tab" (or equivalent) option instead of a full screen or window.
Can I record my microphone too?
Not currently — only the screen and optional system/tab audio are recorded, microphone isn't supported yet.
Which browsers support this?
Any recent version of Chrome, Edge, or Firefox. Screen recording isn't supported on iOS Safari.
