mp3.now is a free online MP3 converter and audio toolkit for everyday sound work — convert WAV, M4A, MP4, MOV, FLAC, AAC, OGG, WMA, AIFF, OPUS and 90+ other formats to MP3 in one click, extract audio from video, compress MP3 files to save space, and run quick edits like trimming, merging, volume normalization and bitrate changes. Everything runs in the cloud — no software install, no signup, no watermarks.

Built for podcasters, musicians, students, office workers and anyone who hits a "wrong file format" error, mp3.now handles the messy real-world cases: pull the soundtrack out of an MP4 or MOV video, turn iPhone voice-memo M4A files into MP3 for any player, convert a FLAC album to MP3 for a car stereo, trim a song down to a ringtone, or merge a folder of clips into one continuous track. Need a phone ringtone? Our MP3 to M4R tool creates iPhone-ready ringtones in seconds.

The editing tools layer handy audio processing on top of the converter: trim or cut an MP3 to the exact seconds you need, merge several tracks into one file, normalize loudness so everything plays at an even volume, and change the bitrate to balance quality against file size. Every tool is free to try, with sensible daily limits and an optional Premium plan for power users.

Privacy is the default. Files are encrypted in transit, stored only as long as the conversion needs them, and automatically deleted within 24 hours (longer on paid plans). We don't read, scan, train models on, or sell your content. Nothing about your file ever leaves the conversion pipeline. If you want files to disappear sooner, just close the tab — the cleanup task handles the rest.
