Supported devices and browsers
mp3.now is a regular web app — it works on anything with a modern browser:
- Desktop: Chrome, Firefox, Safari, Edge, Brave, Opera, Vivaldi — last two major versions of each.
- iPhone / iPad: Safari 14+ and any WebKit-based browser (Chrome on iOS uses WebKit too).
- Android: Chrome, Firefox, Samsung Internet, DuckDuckGo browser — anything from Android 8 onwards.
- Linux / Chromebook: any modern browser.
No app install, no plugin, nothing to side-load. If your browser can open this page, it can run the converter.
Working with phone recordings
iPhones produce M4A by default since iOS 11; modern Androids may produce M4A or MP3. Both work in mp3.now: drop the file straight from the voice memos app into the dropzone and we'll handle it. The same goes for live recordings (we extract the main audio track), multi-track recordings, and voice notes.
Voice Memos on iPhone always records M4A — use our M4A to MP3 converter to get a universally-compatible MP3.
Differences across platforms
The conversion itself is identical on every platform — the work runs on our servers, not your device. The only differences are at the edges:
- iOS Safari sometimes asks twice before letting a site read files from Music. Tap Allow when prompted.
- Android Chrome exposes the playlist via the system file picker — pick from "Files" or "Music" depending on where the track lives.
- Desktop supports drag-and-drop from your file manager and from other browser tabs.
