Video to Audio Converter for iPhone

What the app is for

Every video you actually want the sound from is already on your phone: the lecture you recorded, the voice note someone sent, the clip you filmed. Moving it to a computer to extract audio is the slowest part of the job, and on a train with no signal an online converter is no use at all.

The app does the same work on the device. It reads the video out of Photos or Files, pulls the soundtrack out with FFmpeg running natively, and writes the audio file straight back — no upload, no account, no network. What takes a minute of AirDropping and uploading takes two taps.

What it does, precisely

Pick a video from the gallery or from Files, choose MP3, M4A, AAC or WAV, choose a bitrate from 64 to 320 kbps, and convert. The result lands in a History list with its format and size, so you can play it, share it or send it somewhere else later without doing the job again.

Alongside the converter there are twelve audio tools: a cutter for trimming, compression for making a file smaller, fade in and out, reverse, speed and pitch control, volume adjustment, an equalizer, denoise, reverb and channel control for fixing a recording that came out on one side only.

What it does not do

Three things worth knowing before you install it, because finding them out afterwards is how apps earn one-star reviews.

• One video at a time. There is no batch mode: the picker takes a single file. A folder of recordings is a job for the queue on this website.
• One free conversion. After that it asks for a subscription. The extractor on this site has no limit and never will — they are different products with different costs behind them.
• No links. Like the website, it works on files that are already on your device.

Privacy

The conversion is local, exactly as it is here. Nothing is uploaded, no account is needed, and the app works in airplane mode — which is the simplest way to prove it to yourself.
