How to Make a Video Louder: 7 Methods That Actually Work (2026)

There's nothing more frustrating than recording a video only to realize the audio is barely audible. Whether it's a quiet screen recording, a lecture video with low microphone volume, or a clip from your camera roll that sounds muffled — quiet videos are a universal problem.

The good news: you don't need professional audio software to fix it. Here are 7 methods to make any video louder, ranked from easiest to most advanced.

1. Use a Video Volume Booster App (Fastest Method)

The simplest way to boost video volume is with a dedicated app like Loudify. It's built specifically for this — amplify volume up to 1000%, preview the result, and export in seconds.

How to do it:

1. Open Loudify and select your video
2. Drag the volume slider to your desired level (2x, 5x, or up to 10x)
3. Optionally apply audio filters (noise removal, bass boost)
4. Tap Preview to check the result
5. Export and save to your camera roll

Best for: iPhone users who want a quick, no-hassle solution. All processing happens on your device — nothing gets uploaded anywhere.

2. Use iMovie on iPhone or Mac

iMovie is free and comes pre-installed on Apple devices. It has a simple volume slider that goes up to about 500%.

How to do it:

1. Open iMovie and create a new project
2. Import your video
3. Tap on the clip, then tap the audio icon
4. Drag the volume slider up
5. Export the video

Best for: Apple users who already have iMovie. The downside is it's slower than a dedicated volume booster and has a steeper learning curve.

3. Use VLC Media Player on PC or Mac

VLC is a free media player that can boost volume up to 200% during playback — and up to 800% with a settings tweak. However, this only affects playback, not the actual file.

How to do it:

1. Open your video in VLC
2. Use the volume slider to go above 100%
3. For higher boost: go to Tools → Preferences → All → Audio → set Max Volume to 300-800

Best for: Watching quiet videos on your computer without editing them. Not ideal if you need to save or share the boosted version.

4. Use an Online Video Volume Booster

Several free websites let you upload a video, boost the volume, and download the result. Popular options include VideoLouder, Clideo, and Kapwing.

How to do it:

1. Go to the tool website
2. Upload your video
3. Select the volume increase (e.g., +10dB to +50dB)
4. Process and download

Best for: Quick one-off boosts on a computer. The downsides are file size limits (usually 500MB max), slower processing since it uploads to a server, and potential privacy concerns.

5. Use FFmpeg (Command Line — Advanced)

FFmpeg is a free, open-source tool used by professionals. It's the most powerful option but requires using the command line.

How to do it:

ffmpeg -i input.mp4 -af "volume=2.0" output.mp4

This doubles the volume. You can use higher multipliers like 3.0 (triple) or use decibels: volume=10dB.

For more precise results, use the loudnorm filter to normalize audio to broadcast standards:

ffmpeg -i input.mp4 -af "loudnorm=I=-16:TP=-1.5" output.mp4

Best for: Developers, content creators with technical skills, or anyone processing many videos in batch. Not practical for casual users.

6. Adjust Your Device Settings

Before reaching for a third-party solution, check if your device has built-in settings that can help:

On iPhone:

• Go to Settings → Accessibility → Audio/Visual and check the Balance slider
• Enable Late Night mode in Apple TV+ (compresses dynamic range, making quiet parts louder)

On Windows:

• Right-click the speaker icon → Sound Settings → Loudness Equalization
• This compresses the audio range, boosting quiet parts

On Android:

• Settings → Sound → Music Effects or Equalizer (varies by manufacturer)
• Samsung: Enable Adapt Sound for headphone optimization

Best for: A quick improvement without installing anything. Usually not enough for seriously quiet videos.

7. Use a Professional Video Editor

Software like Adobe Premiere Pro, DaVinci Resolve (free), or CapCut gives you full control over audio levels, EQ, noise reduction, and more.

How to do it (DaVinci Resolve — free):

1. Import your video into the timeline
2. Switch to the Fairlight (audio) tab
3. Select the audio track and adjust the fader
4. Add a compressor or limiter to prevent distortion
5. Export

Best for: Content creators who need precise audio control and are already working in a video editor. Overkill for just boosting volume.

Which Method Should You Use?

| Your Situation | Best Method | |---|---| | Quick fix on iPhone | Loudify app | | Already editing in a video editor | Built-in audio controls | | Watching on PC, don't need to save | VLC player | | One-off boost on computer | Online tool | | Processing many videos | FFmpeg | | Need professional audio control | DaVinci Resolve |

Tips to Avoid Quiet Videos in the Future

• Record in a quiet environment — background noise forces you to lower recording volume
• Get closer to the sound source — even a few feet makes a huge difference
• Use an external microphone — the built-in mic on phones picks up everything
• Check levels before recording — most camera apps show a level meter
• Record a test clip first — 5 seconds of test audio can save hours of frustration

The Bottom Line

For most people, a dedicated video volume booster app is the fastest and easiest solution. You pick your video, slide the volume up, and export — done in under 30 seconds.

If you're on iPhone, Loudify is purpose-built for this. Free to use, no uploads, no account needed.
