[Online Tool] Online Audio Trimmer, Free Cut MP3/WAV Ringtones, Supports Visual Waveform Editing

Want to extract the chorus from a song to make a mobile ringtone, or trim the unnecessary beginning and end of a recording? In the past, this required downloading specialized software like GoldWave or Audacity, taking half an hour just to install and configure.

Not anymore.

With the "Audio Trimmer" from Toolshu, you simply upload your audio file, drag the waveform to select the segment you want to keep, and export it with one click. Processing is done locally in your browser, meaning your files are never uploaded to a server. It supports batch trimming and format conversion, covering all mainstream formats like MP3, WAV, OGG, FLAC, AAC, M4A, and WMA.

Core Feature: Visual Waveform Editing

The most noteworthy aspect of this tool is its waveform editing approach.

After uploading the audio, the tool renders an audio waveform—the horizontal axis is time, and the vertical axis is volume amplitude. You can intuitively drag and select the desired region directly on the waveform. Compared to entering digital timecodes, dragging the waveform allows you to quickly locate "the exact moment the sound starts" or "the point where it gets quiet" without repeatedly listening and adjusting.

Of course, if you need precise control, you can also manually input the start and end times with millisecond accuracy. Both methods can be used together: drag for a rough location first, then fine-tune with numbers for exact precision.

Supported Formats

Input Formats: MP3, WAV, OGG, FLAC, AAC, M4A, WMA, AIFF—almost all common audio formats on the market are supported. Notably, even if your browser cannot directly play certain formats (like WMA), the tool can still preview and edit them through internal transcoding, so you won't encounter "unrecognized format" errors.

Output Formats: After trimming, you can choose to keep the original format or simultaneously convert it to any of MP3, WAV, AAC, M4A, FLAC, or OGG. If you trim a lossless FLAC file and want to compress it into an MP3 for easy sharing, you can do it in one step without needing a second tool.

How to Use Batch Processing?

Upload multiple files at once, set independent trimming intervals for each, and once processed, download them individually or click "Download All" to get a single ZIP archive.

This feature is incredibly useful when processing a batch of recordings—such as organizing meeting recordings into segments, trimming intros and outros for podcasts, or creating batch background music clips for short videos. It saves a lot of time compared to doing them one by one.

Typical Use Cases

Making Mobile Ringtones: Extract the chorus from a song, set it to 30-40 seconds, export as MP3, and transfer it directly to your phone. Note that many phone ringtones have a length limit, which this trimming tool can precisely control.

Trimming Silent Parts of Recordings: Mobile recordings often have a few seconds of silence at the beginning and end, or long pauses in the middle. With the waveform, these spots are easy to find and cut out accurately.

Podcast and Video Voiceover Post-Production: After recording a voiceover, there might be coughs at the start or extra pauses at the end. Trimming them before delivery is much easier here than in professional software.

Extracting Game or Movie Sound Effects: Extract specific sound effect clips from a recorded audio track and save them as assets for later use.

Voice Message Editing: If you recorded a long voice message and want to extract a specific part to send to someone, just trim, export, and send.

All Operations Completed Locally

The tool's computations are executed entirely within your browser. Your audio files are never uploaded to any server.

This is crucial for handling private recordings, meeting audios, or unreleased work samples—you don't have to worry about third parties intercepting your files during uploading or transmission. After processing, download directly locally. The entire process bypasses the cloud.
