Volume Changer

Need to quickly adjust the volume of your audio or video file? Change your video's volume to the perfect level with our free tool.

Change volume

Increase or decrease audio volume online

Increase the volume of any video online with Kapwing's free tool. You can also adjust your video's volume lower so it doesn't distract from your subject, or people speaking in your video. Need to make advanced edits to your audio? Decouple the audio from your video to add music and effects, clean or trim audio, and edit everything in our online audio editor. There's no software to download and it's free to get started.

How to increase the volume of any video

Upload video (or audio)
Click on 'Change volume' and upload the video or audio file you need to edit.
Change the volume
Select the 'Audio' tool from the left sidebar in the Kapwing editor. With your audio track chosen, drag the 'Volume' slider to the right of the screen to increase or decrease the volume. Volume is changed in real time, so play your file back as you adjust to find the right volume.
Export and download
Click on the 'Export Project' button in the top right once you're finished. You can download an MP4 for videos or an MP3 for audio files.

Pitch perfect videos with Kapwing's volume changer

Adjust audio volume in any video

Poor audio quality will cause you to lose viewers—fast. One of the main audio issues that plagues producers is the volume of a video being too soft or too loud in relation to the rest of the content. When the volume is too loud, speakers and other background noise can't be heard. When it's too low, viewers can't hear what's happening. Kapwing's online volume changing tool fixes this by letting you easily adjust the volume of any audio with a simple slider.

Automatically clean your video's sound

Kapwing also features a suite of AI-powered tools that can help clean your audio in just a few clicks. Automatically remove background noise, correct loudness, and fix popping sounds before you start editing.

Or, try out Smart Cut to instantly remove awkward and long silences in your video. Kapwing has everything you need to ensure your videos look and sound professionally-made.

Detach or export audio as an MP3

Kapwing's video converted and audio tools let you separate any audio file from the video it appears in. That allows you to make changes and edits, but it also lets you export and download the audio file separately as an MP3, whether you plan to repurpose it as a podcast or cross-post via a waveform or other formats.

Add Subtitles

Generate and customizable captions that automatically sync to your video. Use our AI-powered tool to create a transcript of your video, and then customize your auto-synced subtitles to make them perfect for your content creation needs. Resize, swap out fonts, or add in professional animations and transitions - all your edits will instantly be applied to the entire video.

Resizer

Repurpose videos faster and make them look more professional with our Resize Canvas feature! In just a few clicks, you can take a single video and adjust it to be the right size for every other platform, whether it's for TikTok, YouTube, Instagram, Twitter, Linkedin, or somewhere else.

With Kapwing's smart background removal tool, you can isolate people from the background of a video for free, without a green screen. All it takes is a few clicks. Upload your content, select the Remove Background tool, and use the preview to choose the threshold that best works for you.

Remove Background

Best online video service ever. And a miracle for deaf people.

[Subtitler] is able to autogenerate subtitles for video in almost any language. I'm deaf (or almost deaf, to be correct) and thanks to Kapwing I'm now able understand and react on videos from my friends :)

By the far the most user friendly software to use.

As a housewife at home looking to start a YouTube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Kapwing is my secret weapon!

This is one of the most powerful, yet inexpensive and easy-to-use video editing software I've found. I blow my team away with how fast and efficiently I can edit and turnaround video projects.

Gracie Peng

Kapwing is king.

When I use this software, I feel all sorts of creative juices flowing because of how jam-packed with features the software really is. A very well-made product that will keep you enticed for hours.

Love this site.

As an English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Heidi Rae

Excellent subtitling features

[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!
