Best Volume Booster Apps in 2026: 8 Apps Tested & Ranked

Looking for the best app to boost video or audio volume on your phone? We tested the most popular options across iOS and Android to find which ones actually deliver louder audio without killing quality.

Here are our top picks for 2026, ranked by ease of use, output quality, and value.

What We Tested For

• Volume boost range — how much louder can it actually go?
• Audio quality — does it distort at higher levels?
• Speed — how fast is the processing?
• Ease of use — can a non-technical person figure it out?
• Privacy — does it upload your files to a server?
• Price — free, freemium, or paid?

1. Loudify — Best Overall (iOS)

Loudify is a dedicated video volume booster that does exactly what it says — makes quiet videos louder. It supports boost levels up to 1000% with quick presets (2x, 3x, 5x, 10x) and a precision slider.

What sets it apart: Besides volume boosting, it includes professional audio filters — noise removal, wind reduction, hiss reduction, bass boost, and voice clarity. You can also extract audio from video as MP3.

• Boost range: Up to 1000%
• Quality: Excellent — smart amplification minimizes distortion
• Speed: Very fast — processes on-device using hardware acceleration
• Privacy: 100% on-device. No uploads, no account, no tracking
• Price: Free with optional premium filters

Verdict: The best option for iPhone users. Fast, private, and produces clean output even at high boost levels.

2. VLC Media Player — Best Free Option (All Platforms)

VLC is the Swiss Army knife of media players. While it's not a dedicated volume booster, its built-in volume control goes up to 200% (and up to 800% with a config tweak).

• Boost range: Up to 200% (800% with settings change)
• Quality: Good up to 200%, distortion above that
• Limitation: Boosts playback only — doesn't save the boosted file
• Price: 100% free, open source

Verdict: Great for watching quiet videos, but not useful if you need to save or share the louder version.

3. XBooster — Best for Android

XBooster tops most Android lists with its 200% boost, 10-band equalizer, 21 presets, and bass enhancer. It's a system-wide volume booster that works across all apps.

• Boost range: Up to 200%
• Quality: Good with the equalizer tuned properly
• Features: 10-band EQ, 21 presets, widget support
• Price: Free with ads, premium removes ads

Verdict: The most feature-rich option on Android. The equalizer and presets give you fine control over the audio profile.

4. Volume Booster GOODEV — Simplest Android Option

If you just want a dead-simple volume boost without any complexity, GOODEV delivers. One slider, no frills, tiny app size.

• Boost range: Up to 70%
• Quality: Decent — clips at very high levels
• Features: One slider. That's it.
• Price: Free, ad-free

Verdict: Perfect if you just want slightly louder system audio on Android without dealing with equalizers and settings.

5. CapCut — Best for Social Media Creators

CapCut (by ByteDance/TikTok) is a full video editor with a volume adjustment slider. If you're already editing your content in CapCut, you can boost volume without switching apps.

• Boost range: Up to about 300% via the volume slider
• Quality: Good, with additional audio effects available
• Features: Full video editor, noise reduction, voice effects
• Price: Free

Verdict: Not a dedicated volume booster, but excellent if you're already editing in CapCut for TikTok or Instagram content.

6. Boom 3D — Best for System-Wide Boost (Mac/Windows)

Boom 3D is a premium desktop app that provides system-wide volume amplification with a 3D surround sound engine and 31-band equalizer.

• Boost range: Significant (doesn't specify exact percentage)
• Quality: Excellent — professional-grade audio engine
• Features: 31-band EQ, 3D surround, per-app volume control
• Price: $19.99 one-time

Verdict: Best choice for desktop users who want permanent, system-wide louder audio across all apps. Premium price but premium quality.

7. FxSound — Best Free Desktop Option (Windows)

FxSound is a free Windows audio enhancer that boosts volume up to 300% with effects like bass boost, surround, and clarity enhancement.

• Boost range: Up to 300%
• Quality: Very good for a free tool
• Features: Volume boost, EQ, bass, 3D surround, clarity
• Price: 100% free
• Limitation: Windows only

Verdict: If you're on Windows and want louder audio without paying, FxSound is the clear winner.

8. iMovie — Best Free Option for Mac/iPhone

iMovie is pre-installed on Apple devices and includes a basic audio volume slider that can boost clips up to about 500%.

• Boost range: Up to ~500%
• Quality: Good, but no noise reduction or audio enhancement
• Features: Basic editing, volume slider, fade in/out
• Price: Free (pre-installed)

Verdict: A solid free option if you're on Apple. But it's a full video editor — overkill if you just want to boost volume quickly.
