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 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.

Frequently Asked Questions

Bob, our kitten, thinking

Is there a Kapwing watermark on exports?

If you are using Kapwing on a Free plan then all exports — including from the Audio Trimmer — will contain a watermark. Once you upgrade to a Pro plan the watermark will be completely removed from your creations.

Is Kapwing's Audio Trimmer free?

Yes, the Kapwing Audio Trimmer is available for free and also includes all manual splitting and cutting tools. However, to use the AI-powered Smart Cut and Remove Background Noise tools, a Pro account is needed.

Is there a way to edit a WAV file?

Yes, you can trim a WAV file using an audio trimmer that supports WAV files or convert them into a more universally compatible file type like MP3. Some tools that support WAV include iMovie and Windows Media Player.

If you want to edit a WAV file, you can use an in-browser audio trimmer like Kapwing, which is integrated with an online video editing suite. This way, you can edit your WAV file and add waveforms, clean audio, and even add an image for subtitles.

How do I cut part of audio?

To cut part of an audio track, you need an audio editor or audio clipper such as Kapwing. Most audio clippers have a playhead you can adjust to make precise cuts. Move the playhead to the section you want to remove, split the section where it begins and ends, and delete.

Then, either stitch your other sections back together or add in new audio to replace the removed portion. Depending on what tool you use, you can cut part of your audio track to make a compressed, smaller audio file or save only the valuable parts you want to keep.

How do you trim audio on iPhone?

You can trim audio on an iPhone using an app or an online audio trimmer such as Kapwing. When choosing an audio trimmer, make sure it supports the type of audio files you're working with. On an iPhone, you most likely have WAV files.

Using a free audio trimmer like Kapwing can help you trim audio directly in your phone's web browser. Simply upload your audio or video content to Kapwing.com and use the "Trim" tool in the right-hand sidebar under "Edit". Kapwing also works on any smartphone, including Samsung Galaxy, Google Pixel, and many more.

What devices and browsers does Kapwing work with?

Kapwing works on any device and browser, though we recommend Chromium-based browsers like Google Chrome and Microsoft Edge. Kapwing also works on iOS and Android mobile devices. Since Kapwing is an online web-based software, it also works across Windows, Mac, and other desktop devices.

What audio files does Kapwing work with?

Kapwing's audio cutter works with a wide variety of popular file types for audio, including MP3, WAV, MKV, WebM, FLAC, and OGG. You can also upload M4A files and either play them or convert them to MP3, though Kapwing's media library can't save M4As for you. Note that audio exports in Kapwing will always be MP3, as we feel this format represents the best tradeoff between file size and quality.

Why does my audio quality go down when I send it?

Larger audio files are generally higher quality, but they're also harder to share. It's a catch-22: the better the quality, the more time-consuming the transfer. There are four main reasons audio quality decreases when you send it to someone:

  • Reduced File Quality: Since uploading large audio files requires a lot of bandwidth, some platforms automatically reduce file quality to speed up uploads. 
  • Compression: Many applications compress audio files to decrease their size, sacrificing some data in the process, which results in lower quality. 
  • File Size Limits: Email and messaging platforms often have file size limits, forcing compression
  • Repeated Downloading and Uploading: Frequent downloading and re-uploading across different devices can further degrade audio quality.

How do I transfer audio without losing quality?

Using an online audio trimmer or an MP3 cutter can help minimize file size without compromising your audio’s fidelty. By trimming redundant and unwanted parts of your audio directly in the browser, you can streamline your content and preserve high-quality files for easy sharing. Kapwing's audio trimmer offers a simple, efficient way to manage file size and enhance the quality of your audio projects.
