MP3 Converter
Convert, edit and keep your own audio
Take the audio out of a video, turn a file into the format your car, your DAW or your old player actually reads, then trim it, merge it, boost it or cut a ringtone from it. Every step runs on the phone — no upload, no account, nothing waiting in someone else’s queue.

01
Convert
Stream-copy first
The engine is an FFmpeg build we compile ourselves. It reads far more than it writes, which is the point.

-
01
Video to audio, audio to audio, video to video
Pull the track out of a film, change a format your player refuses, or re-encode a clip to something smaller.
-
02
Lossless extraction when the file allows it
If the audio inside a container can be copied out untouched, we copy it. No re-encode, no generation loss, and it takes seconds rather than minutes.
-
03
Controls that say what they do
Bitrate, sample rate and channels, with the trade-off spelled out next to each one instead of a slider marked “quality”.
-
04
A queue that survives
Conversions run one at a time so the phone stays cool, continue while you are in another app, and post a notification when the queue empties. A relaunch resumes what was pending.
-
05
Tags and artwork carried across
Title, artist, album and embedded cover art follow the file into its new format instead of being dropped on the way.
02
Studio
Not a DAW
A small editor that finishes the job.
The handful of edits a converted file usually still needs — and nothing that would need a manual.
-
01
Trim, split and merge
Cut on the waveform, split at the playhead, join a set of files into one track.
-
02
Layers with real controls
Per-clip gain, fades, pitch and tempo, mute and solo, laid out on a timeline and mixed down sample-exactly on export.
-
03
Ringtones
Thirty seconds or less, written as .m4r — the format iOS installs ringtones from.
-
04
One-shot tools
Normalise, boost, compress, denoise, reverse, mono to stereo, and a metered microphone recorder that drops straight into the library.
03
Library
Everything in one place
-
01
A player that opens what the system will not
MKV, AVI, OGG, WMA, APE and the rest play inside the app before you decide what to do with them — AV1 video included.
-
02
Your files, organised
Playlists, favourites, recents, search, waveforms, artwork, and a tag editor that writes back into the file itself.
-
03
Get files in without a cable
Wi-Fi transfer from a browser on your own network, the share sheet from any app, paste from the clipboard, Files and Photos.
-
04
On the Home Screen and Lock Screen
Widgets for now playing, quick actions and recent conversions, plus a Live Activity while a conversion runs.

Privacy
No account
Your files never leave the phone, because there is nowhere to send them.
- No account and no sign-in — nothing to identify you by.
- Conversion, editing and playback all run on the device.
- The library is not exposed to other apps through the Files app.
- Purchases go through Apple; we never see payment details.
The free version carries advertising and sends anonymous usage events, both of which are described in full — including who receives what — in the privacy policy.

Questions
Before you download
01 Does MP3 Converter upload my files anywhere?
No. Conversion, editing and playback all run on the device, using the engine built into the app. There is no server of ours to upload to, and the app works with the network switched off.
02 What does “lossless extraction” mean?
Most videos already contain an audio track your phone can play. When the container allows it, the app copies that track out byte for byte instead of re-encoding it — so the result is identical to the audio inside the original file, and it finishes in seconds.
03 Which formats can it write?
Audio: MP3, M4A (AAC), ALAC, FLAC, WAV, AIFF and Opus, plus .m4r for ringtones. Video: MP4 with H.264 and MOV with HEVC, both through Apple’s hardware encoders.
04 What is free and what needs Premium?
The free version converts three files a day, one at a time, to MP3, M4A or Opus, and lossless extraction is included. Premium removes the daily cap, adds batch conversion of a whole queue, and unlocks the lossless output formats. The player, the library and the Studio tools are not behind the paywall.
05 Can I make a ringtone with it?
Yes. The Ringtone tool trims a track to thirty seconds or less and exports it as .m4r, which is the format iOS installs ringtones from.
06 Is it in my language?
The app ships in 28 languages, including English, Turkish, German, French, Spanish, Portuguese, Italian, Dutch, Polish, Czech, Hungarian, Romanian, Swedish, Finnish, Norwegian, Russian, Ukrainian, Arabic, Hindi, Bengali, Thai, Vietnamese, Indonesian, Malay, Japanese, Korean and Chinese in both simplified and traditional script. It follows your device language automatically.
07 Does it work on iPad?
Yes. The app is built for both iPhone and iPad and requires iOS or iPadOS 17.0 or later.
