How to extract audio from a video on iPhone Safari
iOS has no built-in way to save just the audio track of a video — you either need a Mac or you install a converter app. VideoSplit is the third option: it runs in Safari on your iPhone, with no install and no upload, and produces a clean MP3 or WAV.
iOS Safari has memory limits that kick in around 2–3 GB of in-flight data depending on the iPhone model. For very large videos, trim in the Photos app first. Extractions on a 4K 20-minute clip may be slower than on desktop but still work.
Step-by-step
- Open videosplit.io in Safari. The URL in Safari's address bar. No App Store detour.
- Tap Upload video. Safari opens the iOS file picker; grant Photos access if prompted.
- Pick your video. Any MOV or MP4 from your phone's camera roll, downloaded Messenger video, or Files app.
- Pick MP3 for easy sharing. MP3 is small and AirDrops cleanly. WAV works too but is larger.
- Download the audio. Safari saves it to your Files app or Downloads folder.
Tips for better results
- AirDrop the resulting MP3 from your iPhone to your Mac for further editing — it is a zero-latency transfer.
- If Safari crashes on a large file, close other tabs to free memory, or trim the video in Photos to under 15 minutes.
- Voice memos already record as M4A audio — you do not need VideoSplit for those, only for video sources.
