Questions fréquemment posées
Why convert VP9 to MP4?
VP9 videos are commonly stored in WebM containers, which are not supported by all devices and media players. Converting to MP4 with H264 encoding ensures your video plays on virtually any device, smart TV, or media player.
Will I lose quality converting VP9 to MP4?
Notre convertisseur utilise des paramètres de haute qualité (CRF 23) pour maintenir une excellente qualité visuelle. Bien que le réencodage implique toujours une certaine perte générationnelle, la différence est minimale et imperceptible dans la plupart des cas.
What file formats can I upload?

What is the difference between VP9 and VP8?
VP9 is the successor to VP8, developed by Google. VP9 offers significantly better compression efficiency — roughly 50% better quality at the same bitrate. Both are open-source, royalty-free codecs commonly used with WebM containers.
