Trim audio and export MP3
One continuous audio excerpt, optional fades and a smaller MP3 to share.
The check used one synthetic tone sample. It does not assess speech or music quality, mobile performance, maximum file sizes or privacy. Joining recordings and multitrack mixing are outside this workflow.
What you can use it for
- Trim a continuous passage from a recording
- Convert supported audio to MP3 or WAV
- Adjust volume or a loudness target
- Add a fade to the beginning or end of a clip
- Compare MP3 bitrates for a smaller download
Before you choose
Works with one file and one continuous selection at a time. It does not join recordings, delete a middle section and join the remainder, record audio, or mix multiple tracks. Listed inputs are MP3, PCM 16/24-bit WAV, AAC-LC M4A and Vorbis/Opus OGG; outputs are MP3 and PCM 16-bit WAV. The stated file limits are 500 MB on desktop and 100 MB on mobile, with available memory also affecting processing. Refreshing or closing the tab clears the current project. Export prepares a result; use Download to save it. These format and size limits are vendor statements, not a test of every format or maximum size.
Task verification and evidence
Browser workflow check with one synthetic WAV and two downloaded MP3 files. Tested 21 October 2026 on desktop Chrome for Windows. File checks cover duration, decoding, size and fade levels; no subjective listening or privacy audit was performed.
These checks apply to the stated inputs and route. General pricing, platform and processing fields keep their own source dates and unknown values.

Test notes
On 21 October 2026, in desktop Chrome on Windows, we opened a generated 12-second mono PCM WAV at 44,100 Hz (1,058,444 bytes), selected seconds 2-8, switched from the cutter to the fade tool, and confirmed that the selection was retained. We set a 0.25-second fade-in and a 0.5-second fade-out, then exported and downloaded MP3 at 192 and 128 kbps without an account or payment. The downloads were 145,493 and 97,010 bytes respectively. Independent file inspection and decoding found six seconds of mono 44,100 Hz audio in both files; the browser result displayed about 6.03 seconds. Decoded signal measurements showed reduced levels at both ends, consistent with the fade settings. This checks one synthetic tone sample and the download workflow, not speech clarity, music quality, other input formats, all nine tools, mobile use, maximum file sizes or the vendor's privacy claims. No subjective listening assessment was performed. The first export required a substantial audio-engine download; the second completed after that engine had loaded.
