Audio Tools That Stay on Your Device

Everything you need to edit audio, right in your browser — cut, join, convert, transpose, denoise, normalize, and record. Your files never upload. No watermarks, no signup for the basic tools, files up to an hour free.

Audio Cutter

Trim MP3, WAV, FLAC, and OGG with millisecond precision. Make ringtones for iPhone and Android, cut voice memos, pull samples, clip WhatsApp voice notes.

Open Cutter

Audio Trimmer

Shorten the start and end of a recording, or mark sections anywhere in the middle to remove — a cough, a false start, dead air. Several at once, and one trimmed file back.

Open Trimmer

Audio Joiner

Merge tracks end to end into one continuous file. Assemble podcast episodes (intro + interview + outro), join audiobook chapters, combine voice recordings — with an optional crossfade.

Open Joiner

Audio Mixer

Layer tracks so they play together. Add background music under a voiceover, stack a vocal over an instrumental, and balance per-track volume — a mixing console in your browser.

Open Mixer

Audio Converter

Convert WAV to MP3, FLAC to MP3, or OGG to WAV in seconds. High-quality 192 kbps (variable bitrate) MP3 encoding. Shrink files for email, phone storage, or web upload.

Open Converter

Audio Extractor

Pull the audio track out of an MP4, MOV or WebM you already have and save it as MP3, WAV, FLAC or OGG. Your own video files only — no links, and nothing is uploaded.

Open Extractor

Speed & Pitch

Transpose a song to your vocal range, slow down guitar solos to learn by ear, speed up lectures, make nightcore or slowed-and-reverb edits. Live preview before export.

Open Pitcher

Add Reverb

Give dry recordings space and depth. Adjustable room size, damping, and mix, rendered with a natural tail — for vocals, voiceovers, and instruments. Preview before export.

Open Reverb

Silence Remover

Cut dead air out of podcasts and voice memos automatically, or split a long recording at every pause. Adjustable threshold, onset-safe padding, no watermark.

Open Silence Remover

Volume Booster

Make quiet MP3s and recordings louder — lossless maximize to the clipping ceiling, or a fixed boost up to +24 dB with limiter protection. Plus fade, reverse, and stereo/mono tools in the menu.

Open Booster

Audio Recorder

Record voice memos, meetings, interviews, podcast drafts, and singing practice from your mic. Trim on the waveform and export as MP3, WAV, FLAC, or OGG.

Open Recorder

Volume Normalizer

Normalize loudness to -14 LUFS (Spotify), -16 LUFS (podcast), or any custom target. Measures integrated loudness and applies gain with clipping protection.

Open Normalizer

Noise Remover

Remove background noise from podcasts, interviews, Zoom recordings, and voice memos. AI noise suppression optimized for speech — runs locally, no upload.

Open Denoiser

Ringtone Maker

Make custom ringtones for iPhone and Android. Trim to 30 seconds, add fade in/out, and export as MP3 — ready to set as your ringtone.

Frequently Asked Questions

Yes. Every tool is free to use — no ads, no watermarks. Free covers files up to one hour and three files per run; cut.audio Pro lifts those limits, in the browser and in the Windows app.

No. Your audio never leaves your device. Everything is processed locally in your browser. No data is sent anywhere.

MP3, WAV, FLAC and OGG are read directly, and you can convert freely between them. M4A, AAC, Opus and AMR — iPhone voice memos and WhatsApp notes — are read the same way, with the same one-hour limit and no conversion step in between. Output is always MP3, WAV, FLAC or OGG.

There's no server-side limit since files aren't uploaded, and no watermark either. What there is, is a length ceiling: about an hour per file, the same for every format, because the work happens in your browser's memory. Size itself is rarely the problem — most devices handle several hundred MB without issues. Past the hour, the site offers the first part, and cut.audio Pro opens the whole file in the Windows app (up to four hours).

Yes. cut.audio works in any modern browser including Safari on iPhone/iPad and Chrome on Android.

Yes. The Audio Cutter and Ringtone Maker both let you trim to 30 seconds and export as MP3. Android can use that directly; on iPhone, one extra step in GarageBand or Finder sets it as a ringtone.
