About this tool
Cut a part out of an audio file, for example to make a ringtone from a song, keep one answer from a long interview, or drop the silence at the start and end of a recording.
Choose MP3, WAV, M4A, AAC, OGG, FLAC or WebM files, up to 10 at a time and 80 MB in total; the same range is cut from each one. Results keep their format, except that AAC files are saved as M4A, and the audio is copied without re-encoding, so the quality is unchanged. Everything runs in your browser, and the files are not uploaded.
How to use it
- Choose up to 10 audio files, or drop them on the page.
- Enter the “Start” and “End” in seconds or m:ss, such as 75 or 1:15. They are 0 and 10 by default; leave the start empty for the beginning and the end empty for the end of the file.
- Select Run. Each file is cut to the same range.
- Play each result on the page, then download them one by one or all together as a ZIP.

Common questions
Does trimming re-encode the audio?
No, whatever the start time. MP3, M4A, AAC, OGG, FLAC and WebM are cut by copying the original audio data, and WAV keeps its bit depth with the samples unchanged.
Can I cut a part from the middle of an MP3?
Yes. The start can be anywhere: the MP3 frames in the range are copied as they are, so the result is still an MP3 with the original quality.
What if the end is past the end of the file?
The cut simply stops at the end of the file. The start must be earlier than the end and within the file; otherwise the error tells you the valid range in seconds.
Which time formats can I use?
Seconds such as 90 or 90.5, minutes and seconds such as 1:30, or hours, minutes and seconds such as 0:01:30.
Why is the result slightly longer than the range?
Compressed formats such as MP3, AAC and OGG are copied in whole audio frames, so each end can reach up to about a tenth of a second past the time you entered. Common 16-bit and 24-bit WAV files are cut at the exact sample.

Extract audio from video (MP4 to MP3)
Take the sound out of MP4, MOV, MKV or WebM video and convert it to MP3, M4A, OGG, WebM or WAV, or keep the track unchanged in its own container, optionally trimmed. Files are not uploaded.
Convert audio to MP3, M4A, OGG or WAV
Convert MP3, WAV, M4A, AAC, OGG, FLAC and WebM audio to MP3, M4A, OGG, WebM or WAV, with bitrate, sample rate and channels. MP3 is encoded with LAME and the other formats by the browser; files are not uploaded.
Change audio volume
Make audio louder or quieter by a percentage, clipping at full scale, and save it as MP3, M4A, OGG, WebM or WAV.
Convert video format
Convert between MP4, WebM, MKV and MOV; MP4 and MOV get H.264 video and AAC sound so any player opens them, and other formats copy streams when they can. Scale down, remove the sound or trim at the same time. Encoding uses the browser.
Crop images
Crop one region from every image, in pixels or percent, as a rectangle, a circle or ellipse, or a rounded rectangle. Outside a shape is transparent, so JPEG and BMP shapes are saved as PNG.
Split images into a grid
Cut every image into rows × columns tiles, such as a 3 × 3 grid for social posts, optionally from the centred square. Tiles keep the input format and are numbered by row and column.
