How to increase the volume of any video

How to increase the volume of any video
  1. Upload video (or audio)

  2. 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.

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.

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.

Love this site.
As a 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.

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!
