FLV to AACConvertisseur — Rapide et Gratuit

Flash Video (FLV) packages Sorenson Spark or VP6 video in Adobe's Flash container, now largely obsolete following the end of Flash Player support. Advanced Audio Coding (AAC) uses psychoacoustic lossy compression similar to MP3 but with improved efficiency, delivering better quality at the same bitrate. This extracts the audio stream from the video container, discarding the video track. The audio track is decoded and re-encoded (or stream-copied if the codec matches) while the video frames are discarded. The result is a standard AAC file readable by any compatible application. 1converter handles FLV-to-AAC conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
