Why on-device matters

Your files never leave the phone

Decoding uses Apple's own audio engine; the MP3 is written by LAME, on your device. Turn on airplane mode and it still works.

Fast, because nothing is uploaded

A six-second clip converts in well under a second. No queue, no waiting for a server, no file size limit imposed by someone else.

No ads, no tracking, no account

There is no advertising identifier and no account to create. The little the app sends is anonymous and technical — never your files.

What it does

MP3, M4A and WAV

Pick the format and the bitrate — 128 to 320 kbps — and see the estimated file size before you spend the time.

Ringtone cutter

Trim on the waveform, hear the loop, save a .m4r. The 30-second limit is drawn on screen so nothing is a surprise.

Straight from the Share sheet

Send a video from Photos, Files or any app to Tonify and it lands ready to convert.

Your files, where you can find them

Everything you make shows up in the Files app under On My iPhone › Tonify. Share it, rename it, or delete it — it is a normal file.

50 languages

The app speaks 50 languages, from Arabic and Hindi to Japanese and Portuguese.

Verified output

Every file is read back by iOS after it is written. If iOS does not recognise it, you are told — not handed a broken file.

How it works

  1. Pick a video

    From Photos, from Files, or through the Share sheet. The system picker hands over only the file you choose — the app never gets access to your library.

  2. Choose the format

    MP3, M4A or WAV, and the bitrate. The estimated size is shown before anything runs.

  3. Get the file

    Converted on your phone, verified by iOS, saved where the Files app can see it. Share it anywhere.

Privacy, in one paragraph

Tonify does not upload your videos or the audio it makes. Conversion happens on your iPhone using Apple's AVFoundation, the open-source LAME encoder and — for files iOS cannot open by itself — the open-source FFmpeg decoder, which is why it works in airplane mode. There is no advertising identifier, no ads and no account. The app does use the network, for these things only: to load settings we can change without an update; to keep an anonymous device record (a random ID with your language, app version and a few counters); to send anonymous usage events — what kind of job ran, whether it worked and how long it took, never file names, links or contents; to verify your subscription through RevenueCat and the App Store; and — only when you use “From a link” — to fetch the address you paste. Tonify does not download from YouTube, TikTok or similar services; their terms do not allow it.

Questions

Can it download from YouTube?
No. Tonify converts videos that are already on your phone. Downloading from streaming sites is against the App Store rules and we do not do it.
Can the app set my ringtone automatically?
No app can — iOS does not allow it. Tonify makes the .m4r file and shows you the two ways to install it: the system's own Use as Ringtone action on iOS 26, or GarageBand on iOS 18.
Is there a free version?
You get one free conversion so you can see it work. After that, Pro unlocks unlimited conversions, all formats and ringtones. The price, the renewal date and how to cancel are all shown on the purchase screen before you pay.
What formats can it read?
Anything your iPhone can play: MP4, MOV, M4V, HEVC, and audio files like M4A, WAV or AAC. DRM-protected files cannot be read by any app.
How long can a video be?
There is no limit built into the app. Long files take longer and need free space for the output. On iOS 26 a conversion keeps going when you switch to another app; on iOS 18, keep Tonify open while it runs.
Where do my files go?
Into the Files app, under On My iPhone › Tonify. They are ordinary files: move them, share them, back them up.
