A web-friendly format with strong browser support.

FAQ

Preguntas frecuentes

Are vídeos and thumbnails uploaded?

No. Procesando happens locally in your navegador, and the source vídeo is not sent to a server.

Why can I seleccionar an MKV or AVI but not vista previa it?

Native vídeo vista previa support varies by navegador, container, and codec. MediaBunny reads the track independently, so extraction may still work even when vista previa does not.

Are thumbnails exported at the original resolution?

The JPG uses the vídeo display dimensions by default. Archivo tamaño depends on the source resolution and JPG calidad.

Why does the first frame not iniciar at 0 seconds?

The default rango starts at 5% and ends at 95% to avoid black frames, intros, and end cards. Arrastrar the iniciar posición to 0% when needed.

How many frames can I extract at once?

The page supports up to 24 frames. Más frames require más local memory for decoding and JPG encoding.

Can I use this on a phone?

Yes. Modern mobile browsers usually handle MP4 and WebM. Large archivos or uncommon codecs may take longer.
