Description
Online Audio Converter is a free web app from 123apps that converts audio files quickly without installing any software. It works with over 300 file formats, including video formats, and can output MP3, WAV, M4A, FLAC, OGG, AMR, MP2, and M4R for iPhone ringtones.
The converter lets you open files from your device, Google Drive, Dropbox, or a URL, then choose a target format and quality from Economy to Best (up to 320 kbps). Advanced settings give control over bitrate, sample rate, channels, and effects such as reverse playback and fade in or out, and you can edit track information like title, artist, album, year, and genre.
It also extracts audio tracks from video files, supports batch conversion of multiple files into a ZIP archive, and automatically deletes uploaded files from its servers a few hours after you finish. A free plan allows 70 files per day with a 4 GB file size limit, while a Premium plan adds unlimited files, larger uploads, faster speed, and no ads.
