Tonik: Video to MP3 Converter

Tonik turns any video into MP3 — right on your phone, in seconds. Convert MP4 to MP3, extract audio from video, or convert between audio formats with a clean, fast audio extractor that never uploads your files.

Pick a video (or fifty), choose a format and quality, and Tonik decodes the audio track with your phone's own media engine. No servers, no account, no waiting for an upload. Your files never leave your device.

FIVE FORMATS, ONE TAP
• MP3 — plays everywhere, with cover art and tags built in (64–320 kbps)
• M4A (AAC) — copied losslessly from MP4 in seconds, no re-encoding
• WAV — uncompressed, for editing and studio work
• FLAC — lossless at about half the size of WAV
• OGG (Opus) — the smallest files (Android 10+)
• Best / High / Standard / Small presets, or set your own bitrate, sample rate and mono/stereo

TRIM BEFORE YOU CONVERT
See the waveform, drag the handles or type the exact start and end time — precise to a tenth of a second. Preview the selection before you convert. Perfect for making a ringtone from your favourite part of a song, or cutting a voice memo down to the bit that matters.

COVER ART AND TAGS, DONE FOR YOU
Tonik takes a frame from the video as cover art and fills in the title, artist, album and year for you. Edit them before converting; they are written into the MP3 so every music player shows them.

BATCH CONVERTER
Queue up to 50 files, watch the live progress, and switch to another app — Tonik keeps converting in the background and tells you when it's done. Each file shows its estimated size before you start.

AFTER CONVERTING
• Saved to Music › Tonik automatically, so it appears in your music player right away (or keep it inside the app until you tap Save)
• Play it in the built-in player, share it to WhatsApp, Telegram, Drive or email
• Set it as your phone ringtone, notification sound or alarm
• Delete the bulky original video in one tap
• History keeps everything you've converted

MORE THAN A VIDEO TO AUDIO CONVERTER
• Audio converter: MP3 to WAV, M4A to MP3, FLAC to MP3, OGG to MP3 and every other combination
• Volume boost (up to 200%), fade in and fade out
• Screen recordings, lectures, voice notes, concerts, podcasts — any video your phone can play (MP4, MOV, MKV, WebM, 3GP, AVI…)

LIGHT, FAST, POLITE
• Works fully offline. No upload, no waiting.
• AAC audio from MP4 is copied without re-encoding — a full-length film's soundtrack in seconds
• Ads are kept out of your way: never before your first conversion, never during one
• Light, dark or follow-system appearance
• Available in English, Hindi, Spanish, Portuguese, Indonesian, Russian, Arabic, French, German, Turkish, Japanese, Korean, Vietnamese and Chinese

PRIVATE BY DESIGN
• Files are selected with the Android photo picker and file picker — Tonik never asks for access to your whole gallery or music library
• Nothing is uploaded. There are no servers.
• No sign-up, no email, no tracking of what you convert

Tonik is a tool for your own videos and recordings. It does not download from YouTube, Instagram, TikTok or any other website.

Tonik is free and supported by ads. Conversion itself works without an internet connection.
