Batch Settings
Vous avez des fichiers RMVB et souhaitez les convertir au format AAC pour une meilleure compatibilité ou une qualité audio optimisée ? Le format RMVB, autrefois populaire pour le streaming vidéo en ligne, est de moins en moins pris en charge par les lecteurs modernes et les appareils mobiles. L'AAC, en revanche, est un codec audio largement adopté, reconnu pour son excellent rapport compression/qualité, ce qui en fait un choix idéal pour l'archivage audio, la diffusion sur le web ou l'écoute sur divers supports. Notre outil de conversion simplifie ce processus, vous permettant de transformer vos fichiers RMVB en AAC avec efficacité, sans perte audible perceptible et en quelques clics seulement. Redonnez vie à vos anciennes vidéos en extrayant leur bande sonore dans un format universellement compatible.

- Conversion de bandes sonores de films québécois

En France et en Belgique, l'adoption de l'AAC est quasi universelle pour la diffusion numérique, tandis que le RMVB est désormais très marginal, même pour les contenus d'archives.
About RMVB to AAC Conversion
Short answer: yes, you can convert RMVB to AAC online for free, and quality is well preserved with the right settings. Just upload your .rmvb file to CocoConvert, pick AAC as the output, and click Convert. The whole process takes seconds.
Now for the details. RMVB is a widely used file format. AAC (Advanced Audio Coding) offers better quality than MP3 at the same bitrate — the default codec for Apple devices. Converting between these two formats lets you convert between formats quickly.
Your RMVB file is decoded and re-encoded as AAC. Converting RMVB to AAC maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
