Pantalla grabación guide
Record your pantalla en línea without installing software
This free pantalla grabadora captures your pantalla, a window, or a navegador tab directly in the navegador. Añadir micrófono narration, system audio when compatible, or a cámara picture-in-picture overlay. The grabación and formato conversión stay on your device.
Compatible grabación formats
The grabadora checks MediaRecorder.isTypeSupported() in the actual navegador and only shows formats it can actually create. Direct MP4 grabación is browser-dependent; WebM is the usual fallback.
WebM · VP8 / VP9 + Opus
The most common browser-native grabación formato. It is usually available in Chrome, Edge, and Firefox and keeps archivos relatively small.
MP4 · H.264 + AAC
The most compatible formato for phones, editing apps, presentations, and sharing. Direct grabación depends on the navegador and operating system.
Local MediaBunny conversión
If your navegador records WebM, convertir the finished grabación to MP4 or WebM in a Worker without sending the archivo to a server.

How privacidad works
The navegador permission prompt controls access to your pantalla, cámara, and micrófono. The streams are assembled into a MediaRecorder Blob locally. Optional MP4 or WebM conversión runs in a local MediaBunny Worker. Nothing is uploaded or stored on our servers. Stop sharing and cerrar the tab when you are finished to release the streams.
FAQ
Preguntas frecuentes
Will my pantalla grabación be uploaded?
No. Pantalla, cámara, micrófono, vista previa, and optional MediaBunny conversión stay in this navegador tab. This page does not subir the grabación.
Why can’t I record system audio?
System audio is controlled by the navegador and operating system. Check Share audio in the screen-share picker, and remember that some browsers only offer it for a tab or window.
Why is MP4 unavailable?
MediaRecorder support varies by navegador. Record WebM first, then use the local MediaBunny conversión button to create an MP4 when the navegador codecs allow it.
Does cámara picture-in-picture work everywhere?
The overlay uses Canvas capture. If that API or cámara permission is unavailable, the herramienta falls back to pantalla grabación and explains the fallback in the status message.
What navegador is required?
Use a actual navegador with getDisplayMedia and MediaRecorder support over HTTPS or localhost. Keep the tab open while grabación and converting.
How can I reduce archivo tamaño?
Record only the needed window or tab, keep clips short, avoid unnecessary cámara overlay, and comprimir or trim the resultado antes sharing.
