Store description
Volume Booster helps you make quiet videos and audio files louder directly on your iPhone or iPad. Pick media from Photos or Files, choose how much extra volume you want, preview the result, then save a boosted copy to your library.
Use it when a video was recorded too softly, a lecture is hard to hear, a voice note needs more power, or an audio file sounds lower than the rest of your collection. The flow is simple: import, boost, compare, save.
Raise volume from the original level up to 1000 percent with Premium. Free users can boost up to 299 percent. The volume slider shows both percentage and dB, so you can choose a level that feels right instead of guessing. A live level meter helps you see what is happening while you adjust, and the built-in soft limiter helps keep boosted audio usable instead of turning loud moments into harsh clipping.
Volume Booster works with both videos and audio files. For videos, the app boosts the sound while keeping the original video track intact, so your footage stays as it was. For audio-only files, the app creates a boosted M4A file that you can play, rename, keep, or share.
Want more low end? Premium also includes Bass Boost, a simple control that adds punch to low frequencies without changing your selected volume level. It is useful for music clips, workout videos, party edits, and anything that needs a fuller sound.
