Can I trim and export an audio clip for free?

Yes. Trimming, gain, fades, undo and export are all local browser functions — no account and no watermark. The online audio editor stays free because your own machine does the work; optional AI vocal separation elsewhere on the site is the only feature with computing costs.

Does the online audio editor support multiple tracks?

No, and it says so rather than faking it. One stereo file at a time, with a full operation history — no multitrack timeline, buses or plugin slots. For cutting, leveling and fading a single file, that scope is exactly the right size.

Will my edits match the exported file?

Yes — the online audio editor renders export from the same operations you hear in preview: identical trim points, identical gain, identical fade curves. Nothing is applied at download time that you did not already audition, which is the definition of a trustworthy editor.

Can I undo in the online audio editor after exporting?

Within the session, yes — undo and redo keep working after a download, so you can export one version, walk the history back, and export another. Close the tab, though, and the session ends; the exported files are the record of what you made.

What audio formats can I load and save?

MP3, WAV and M4A load according to your browser's decoding support, and the online audio editor tells you immediately when a file will not decode. Saving offers WAV always and MP3 when an encoder is available — never a mislabeled file with the wrong extension.

Online Audio Editor

An online audio editor with a real waveform: set in and out points, trim, adjust gain, shape fades and undo anything — in your browser, with an export that matches the preview exactly.

How it works

Load audio from your computer or pick up a track you just extracted or separated elsewhere on the site. The online audio editor draws the full waveform, lets you scrub and mark in and out points, trim the selection, raise or lower gain, and add fade-in and fade-out curves — every change is non-destructive until you export. Undo and redo step back through your edits, and this online audio editor is the finishing bench for every audio job on the site.

1
Open your audio
Drag in an MP3, WAV or M4A file, or continue with a track from the extractor or a vocal separator. The waveform appears immediately, and playback follows your cursor so you can navigate by ear before touching an edit.
2
Mark and trim
Click to set an in point and an out point around the passage you want, then trim away the rest. The editor keeps the removed audio in history, so an overzealous cut is one undo away rather than a lost take.
3
Shape gain and fades
Nudge gain up or down in decibels to level a quiet passage, and set fade lengths so edits begin and end gently. The online audio editor previews every adjustment live, and playback always reflects the current settings rather than a promise.
4
Export from the online audio editor
Choose WAV for a bit-perfect copy of your edits or MP3 for a lighter file when an encoder is available. The render applies exactly the operations you previewed — trim, gain and fades in order — so the download matches what you heard.

A real waveform online audio editor, not a toy

The online audio editor opens on a timeline you can scrub, not two sliders pretending to be software.

Editing starts with listening. The online audio editor renders the full waveform so silence, speech and music are visible at a glance, and the playhead tracks your position as you audition the material. Marking an in point and an out point is two clicks; the selection between them is what every later operation touches.

Trimming then behaves the way you expect from serious tools: the cut lands where you marked it, the removed audio stays available through undo, and edges come out clean without pops because short gain ramps are applied where the waveform meets silence. A 20-second file trimmed to the eight seconds that matter is an eight-second file in any online audio editor — here it is verified, not approximated.

Gain, fades and polish inside the online audio editor

Gain moves the whole file or your selection up and down in decibels; fades shape the first and last moments of a clip so nothing starts or stops abruptly. Used together, they solve the most common finishing tasks the online audio editor sees — leveling a voice memo, smoothing a rough cut, taming a loud intro.

Undo that actually protects you

Every operation in this online audio editor lands on an undo stack, and redo is right beside it. Experiment with an aggressive trim, a hot gain boost, a long fade — then walk the history back and confirm you returned to where you started. Non-destructive until export means exactly that: nothing is final until you render.

What this online audio editor is not

It is not a digital audio workstation, and it does not pretend to be one. There are no multitrack timelines, plugins, noise reduction or automatic mastering — a clear, single-track scope is what keeps the tool fast, free and honest. The online audio editor does the jobs most people actually have: trim this, level that, fade the ends, export.

That restraint is deliberate. Browser tools earn trust by doing a few things verifiably well; every promised feature that is not really there costs more than it returns. When a job genuinely needs a DAW, this online audio editor will still prepare the clip — trimmed, leveled, faded — so the heavy software starts from a clean file.

Where the online audio editor gets its audio

The online audio editor is the natural second stop on this site. Audio you pull out with the extract audio from video tool, or stems you get from a vocal separator, arrive here ready for refinement: trim the intro, fade the outro, level a passage, then export. Nothing is re-uploaded between steps when both tools run in the same browser.

Plain uploads are equally welcome in the online audio editor: a voice memo from your phone, a rehearsal recording, a podcast draft. If the file decodes in your browser, it edits here — and when a codec is genuinely not supported, you get a clear message instead of a broken waveform.

How the online audio editor exports

Export runs locally and renders from your operation list, so the file you download is the file you previewed — same length, same gain, same fades. WAV is always available; MP3 appears only when your browser exposes a working encoder, and the button never offers a format it cannot honestly produce. The online audio editor treats output integrity as the whole point.

Re-import your own export to verify it: the trimmed file opens, plays and edits again like any other audio. That round-trip — edit, export, re-open — is the quiet test of any online audio editor, and it is one this page is deliberately built to pass.
