Cómo usar Quitar partes
- Elige un archivo de audio o vídeo.
- Añade inicio y fin para cada parte que quieres eliminar.
- Descarga el archivo final sin esas partes.
What this tool does
Cut out parts removes one or more unwanted time ranges and keeps the rest of an audio or video file. Use it for pauses, delays, private details, mistakes, or short sections that should not appear in the final export.
Unlike trimming, this does not keep only one continuous range. It keeps the sections before and after each removed part, then joins them into one MP3 or MP4.
How browser processing works
The selected file is processed locally with FFmpeg WebAssembly. Audio is joined into MP3 in one pass; video uses temporary kept segments that are joined into an MP4.
Supported formats and output
- Input
- MP3 audio and browser-readable video files supported by the browser FFmpeg engine.
- Output
- MP3 or MP4 containing the original file minus the removed time ranges.
Practical examples
Remove a delay
Cut out 5:36 to 5:49 to remove a pause while keeping the video before 5:36 and after 5:49.
Remove private details
Cut out a short section that shows unwanted information, then export the remaining video as one MP4.
Quality considerations
- Use precise start and end times such as 5:36 and 5:49 for minute-second inputs.
- Because the kept parts are merged, the final video duration should be the original duration minus the removed ranges.
Limitations
- Video cuts are re-encoded for compatibility, so processing can take longer than a simple trim.
- Removing many ranges from a large file can use significant browser memory.
- If the source contains unusual audio or video codecs, export may fail in some browsers.
Preguntas frecuentes
¿Es diferente de recortar?
Sí. Recortar conserva un rango seleccionado. Quitar partes elimina los rangos seleccionados y conserva todo lo demás.
¿Puedo eliminar más de una parte?
Sí. Añade varios rangos, por ejemplo 0:15 a 0:20 y 1:05 a 1:09.
¿Se sube mi archivo?
No. La eliminación y unión se ejecutan localmente en tu navegador con WebAssembly.
Troubleshooting
I removed 5 seconds, but the final duration is not exact.
Video timestamps and frame boundaries can vary slightly. Try adjusting the start or end time by a fraction of a second if the cut lands early or late.
The export fails after several ranges.
Try fewer ranges first, close other heavy tabs, or split the source into smaller parts before cutting.
