FAQ

Does this upload my screenshot anywhere?

No. Everything stays in your browser. No data is sent to any server.

What browsers support this?

Chrome, Edge, Firefox, and Opera support the Screen Capture API. Safari has limited support.

Can I capture a specific window or tab?

Yes! The browser will show a picker letting you choose your entire screen, a specific window, or a browser tab.

PNG vs JPEG — which should I use?

Use PNG for crisp text and UI screenshots. Use JPEG for photos or when file size matters (e.g., email attachments).
