Trim Audio

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.

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.

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.

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.

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.

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.

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.

Trimming removes unwanted parts of a recording, but exporting can affect audio quality depending on the output format and compression settings.

Kapwing exports audio as MP3, so uploading a WAV or another format doesn't preserve the original file format. For the best results, start with a high-quality recording and review the exported audio before sharing.
