How It Works
Upload Audio
Upload an MP3, WAV, M4A, FLAC, or OGG file. Once uploaded, the tool reads the total duration and displays it so you can plan your trim points accurately. The audio is available for preview playback in your browser — listen to identify exact start and end timestamps before trimming. Files up to 50 MB are accepted in the free tier.
Set Trim Points
Enter start time and end time in minutes:seconds format (e.g. 1:30 for 1 minute 30 seconds, or 0:45 for 45 seconds). Leave end time blank to trim from start to the end of the file. Optionally add a fade-in and/or fade-out of 0.5–3 seconds to prevent abrupt audio cuts. This is essential for creating clean audio samples, ringtones, and podcast clips.
Download Trimmed Audio
Download the trimmed audio in the same format as the input (e.g. trimmed MP3 from an MP3 source) or convert the format at the same time — for example, trim an M4A and output as MP3. The trimmed file retains the original audio quality — only the portions outside the trim range are removed, not re-encoded at lower quality.
Audio Trim Features
Precise Time-Based Trim
Set start and end times in mm:ss format with sub-second precision. For example, 2:34.5 trims to 2 minutes, 34.5 seconds. This is more accurate than dragging a timeline and essential for creating clips that need to start or end at a specific beat, spoken word, or sound event. The trim is applied at the exact millisecond level on the server.
Fade In & Fade Out
Add a linear amplitude fade at the start (fade in) and/or end (fade out) of the trimmed clip. Fade durations of 0.5, 1, 2, or 3 seconds are available. Fades prevent the harsh click or pop that occurs when audio is cut abruptly mid-waveform. They are essential for creating music previews, podcast intros, and ringtones that sound professional rather than abruptly cut.
All Major Audio Formats
Supports MP3 (MPEG Layer 3), WAV (uncompressed PCM), M4A (AAC in MPEG-4 container), FLAC (lossless compressed), OGG Vorbis (open-source lossy), and MP4 audio tracks. Output can be in the same format as input, or you can convert format during trim — useful for extracting an MP3 ringtone from an M4A or cutting a WAV clip and converting it to MP3 for sharing.
Browser Audio Preview
After uploading, the audio is previewed in a browser audio player so you can listen to it and identify exact trim timestamps by checking the playback time counter. Pause at the desired start point to read the exact timestamp before entering it in the start time field. This eliminates guesswork and ensures your trim points are accurate without any additional software.
Quality-Preserving Trim
For formats that support keyframe-based trimming (WAV, FLAC, AIFF in Pro), the trim is performed without re-encoding — only the sample boundaries are adjusted. For MP3 trimming, the file is decoded and re-encoded at the same or higher bitrate to ensure the trim boundary is at the exact sample. This produces the cleanest result with minimal quality degradation.
Private & No Account Needed

Frequently Asked Questions
After uploading, use the browser audio player to listen and pause at the desired trim point. The playback time shown in the player (e.g. 1:23) is the timestamp to enter in the Start or End Time field. For more precision, drag the player progress bar to fine-tune the position. Alternatively, use an audio editor like Audacity (free, desktop) to identify exact timestamps before using this tool for the actual trim.
Trimming an MP3 requires decoding and re-encoding, which technically applies a second round of MP3 compression. At high bitrates (192 kbps+) the quality loss is imperceptible. At lower bitrates (128 kbps or below), a second encode may introduce slight additional artifacts. To avoid any quality loss: trim the MP3 and output as WAV (no re-compression), then if needed convert the WAV back to MP3. Alternatively, trim a lossless FLAC or WAV source for zero-quality-loss trimming.
Removing a section from the middle of a track (cut-out editing) requires multi-segment extraction, which is a Pro tier feature. With multi-segment extraction, you define multiple keep regions (e.g. keep 0:00–1:30 and 2:45–end) and the tool stitches them together, removing the unwanted middle section. The free tier extracts one continuous segment defined by a single start and end point.
Most ringtones are 20–30 seconds long. Find the chorus or hook of the song you want — use the audio player to identify the timestamp where it starts and ends. Enter those times, add a 1s fade out so the ringtone doesn't cut abruptly, and select M4A as output format (M4A is the standard ringtone format for iPhone; AAC in M4A container). For Android, MP3 output works on all devices. The trimmed file can be set as a ringtone directly from your phone's settings.
Manual trimming (set start/end time) works well for removing a silent intro or outro — listen to find where speech starts and ends, then trim accordingly. For automatic silence removal throughout a recording (removing all pauses and gaps in speech), use the Silence Detection Auto-Trim feature in the Pro tier, which analyses the audio waveform and automatically removes segments below a configurable dB threshold.
