Questions people often ask.
Does audio cutter and trimmer upload my data?
No. This tool processes your input inside your browser. Your text and files are not sent to an application server. The static host receives page and asset requests; see our privacy explanation.
Is this tool free for work and study?
Yes. No account, paid API, usage subscription or watermark fee is required. You remain responsible for your content rights and checking results. Hosting providers and their free tiers are separate from this open-source software.
What should I check before relying on the result?
Most MP3, WAV, M4A, AAC, OGG, Opus, WebM and FLAC files work, depending on your browser. Maximum 20 MB in total and about 5½ minutes of stereo or 11 minutes of mono. The result is an uncompressed 16-bit WAV file of up to 40 MB. Your original files are not changed. Review important outputs against the source, especially financial, legal, identity, medical and research calculations.
Which audio files can I use?
Most MP3, WAV, M4A, AAC, OGG, Opus, WebM and FLAC files work, depending on your browser. If a file does not open, convert it to WAV or MP3 with another app first.
Why is the WAV result larger than my MP3?
WAV is uncompressed, so it keeps every sample. That makes it ideal for editing and compatibility, but larger. Choose Mono, or 16 kHz for speech, to make it smaller, or use Compress audio file for a small Opus file.
Is my recording uploaded anywhere?
No. Your browser decodes the audio, and a worker on your device cuts, joins and saves it. Nothing is sent to a server or kept after you close the page.
