About Audio Converter
Last updated: May 2026
OptiPix Audio Converter transformerer lydfiler mellem alle større formater direkte i din browser. Konverter MP3, WAV, OGG, FLAC, AAC/M4A, WMA, AIFF, WebM, OPUS og AMR filer til dit ønskede outputformat. Kontroller bitrate (64-320 kbps), sample rate (22050-48000 Hz) og kanaler (mono/stereo). Batchkonverter flere filer på én gang. Bruger FFmpeg.wasm til professionel kodning uden kvalitetstab ud over måformatets karakteristika. Estimeret outputfilstørrelse vises før konvertering. Al behandling sker lokalt – dine lydfiler forlader aldrig din enhed.
How It Works
Konverteren bruger FFmpeg.wasm til at afkode din inputlyd og genkode den i måformatet med dine specificerede bitrate-, sample rate- og kanalindstillinger. Al behandling kører lokalt i din browser.
