You Don't Have to Choose Between "Online" and "Private"
Ask anywhere how to edit audio and you'll get the same two options: upload your file to a website, or install desktop software like Audacity. Online tools are convenient but your recording sits on someone else's server; desktop editors keep files private but mean downloads, installs, and updates.
There is a third option most lists never mention: an editor that runs in your browser but does all the work on your own device. PitchChanger.io decodes, edits, and exports your audio locally — the file never leaves your computer or phone. You get the convenience of a website with the privacy of desktop software.
No upload also means no waiting. A 100 MB recording starts editing in seconds, because there is nothing to transfer — and it works on a weak connection.
What You Can Edit — and Which Tool Does It
PitchChanger.io's editor is a suite of focused tools that share one design: pick the one job you need, do it fast, download the result.
Cut, delete, and rearrange sections
The Audio Cutter splits a song anywhere, removes the parts you don't want, and lets you reorder the pieces. Every join gets an automatic crossfade so cuts don't click, and beat snapping keeps a shortened song in time.
Trim the start and end
The Audio Trimmer tops and tails a recording and adds fade-in/fade-out with three curve shapes — the quickest fix for voice memos and ringtones.
Add effects
Reverb and delay, immersive 8D rotation, or the classic slowed + reverb and nightcore treatments — each with real-time preview.
Master and polish
The Online Mastering tool applies EQ, compression, limiting, and loudness normalization so your track sounds finished.
Convert formats
Switch between MP3, WAV, FLAC, AAC, OGG, and more — with quality controls and batch support.
Change pitch and speed
The pitch changer that gives this site its name: shift the key of any song without changing its speed, or change speed without chipmunking the pitch.
How to Edit a Song in Your Browser
1. Drop your file into the Audio Cutter
MP3, WAV, FLAC, M4A/AAC, or OGG up to 250 MB. Decoding happens on your device, so even large files open in seconds.
2. Cut, rearrange, and fine-tune
Tap the waveform to place the playhead (it snaps to the detected beat), split, delete or reorder pieces, and drag the edges of any piece to resize it. Zoom in for sample-accurate cuts; undo anything.
3. Preview and download
The preview is identical to the export — what you hear is exactly the file you get. Download as WAV (lossless) or MP3.
Why "No Upload" Matters More Than It Sounds
Every online editor that uploads your audio is asking you to trust a server you can't see — with unreleased demos, client work, voice memos, and interviews. Local processing removes the question entirely: there is nothing to leak, because nothing is sent.
It's also simply faster. Upload-based editors spend most of their time moving your file up and down the internet. A local editor spends that time editing.
Tip: you can confirm it yourself — load the editor, switch off your Wi-Fi, and keep editing. Everything still works.
Frequently Asked Questions
Is this audio editor really free?
Yes — every tool is free with no account, no watermark, and no export limits. The site is supported by a small sponsor banner.
Does my audio get uploaded anywhere?
No. Decoding, editing, effects, and export all run locally in your browser using the Web Audio API. Your file never leaves your device — you can even edit with your internet connection switched off.
How is this different from installing Audacity?
Audacity is excellent, but it's a desktop install with a learning curve. This editor opens in one click on any device — including phones and school or work computers where you can't install software — and keeps the same privacy, because nothing is uploaded.
How is this different from other online audio editors?
Most online editors upload your file to their servers to process it. Here, the processing happens on your own device — faster for big files, private by design, and it works on a poor connection.
What formats and file sizes are supported?
MP3, WAV, FLAC, M4A/AAC, and OGG files up to 250 MB. Exports are WAV (lossless) or MP3. The Audio Converter tool handles format switching, including batch conversion.
Can I edit audio on my phone?
Yes — the editor is touch-first: tap to place the playhead, pinch to zoom the waveform, and drag piece edges with your finger. Everything runs locally on the phone, just like on desktop.
Ready to Edit Without Uploading?
Open a tool and drop your file in — you'll be editing before an upload-based editor would have finished transferring.
