What makes it nightcore and not just fast

Speed and pitch, raised together, by the same ratio. Raise only the speed and you get the same song, sooner. Let the pitch climb with it — the way a record climbs when the platter spins faster — and the voice lightens, the track gains urgency, and it reads as nightcore.

The tool above keeps that link on, always. The relationship is fixed physics: twelve semitones per doubling of speed, so 135% works out to +5.2 semitones. At 125% you are at +3.9 — bright, but the singer still sounds like themselves. By 150% you are at +7, which is deep chipmunk territory and usually a step too far. The preset lands at 135% because that is where the genre lives.

The numbers, so the readout makes sense

Where the export goes

The export button writes the whole song, at the speed you chose, as an MP3 or WAV — free, with a short spoken note after the music ends. It starts after the last note on purpose: trim it and it was never there. Post the result, loop it, build an edit on it. It is your file; it never even left your device.

Where the sound came from

Nightcore started as two Norwegian students speeding up trance and eurodance tracks in the early 2000s and naming the project after themselves. The template — faster, higher, relentless — outlived the duo by decades because anime editors and early YouTube channels adopted it as a house style: the lifted vocal cut through tinny laptop speakers, and the urgency matched the montages it was cut to. What you are making with the slider above is the same object those channels made with pitched-up WinAmp plugins, minus the software archaeology. The genre never needed more than the one move, done at the right number, to the right song.

If it sounds wrong

Nightcore has two classic failure modes, and both are the source song’s fault rather than yours. A track with a deep, slow vocal usually survives the lift best — that is why so much classic nightcore is built from ballads. A song that is already bright and fast turns shrill; back the slider off toward 128% or pick a different track. And if the low end vanished, that is physics — everything moved up, including the bass. The app’s EQ exists for exactly this: lift the lows back in after the speed change, which the browser version cannot do.

Start to finish, ninety seconds

The whole job, in the order it actually happens.

1. Drop the file. Tap the dashed box or drag a song onto it — MP3, M4A, WAV or FLAC, anything you own. It starts playing at 135% the moment it decodes; nothing to press.

2. Find the song’s number. Drag the tempo while it plays. Every song has a spot where the voice turns silver without turning cartoon — usually within a few percent of 135, sometimes down at 128 for tracks that were bright to begin with. The pitch readout follows on its own; that is the link doing its job.

3. Loop the chorus if you are deciding. The ↻ button repeats the song so you can A/B the same passage at two speeds without restarting.

4. Export. MP3 for posting, WAV if it is going into an editor next. The whole song renders in seconds — faster than it plays — and lands in your downloads with the settings in the filename, so song (135%).mp3 still makes sense next week.

Phone, laptop, whatever

The page runs the same in mobile Safari, Android Chrome, and every desktop browser — there is no install and no account on any of them. Phones handle typical songs fine; very long files on older phones can run out of decode memory, which is a hardware ceiling, not a paywall. On a computer, drag-and-drop from a folder is the fastest route. On an iPhone, the app is the better long-term home: it keeps the whole library in nightcore, offline, with the visualizers on screen.

You love nightcore? There is a player for that.

Not a converter you visit — a music player where nightcore is how your library sounds. Every song remembers its speed, your playlists play that way, and the whole thing runs offline.

Your library imports once and plays at whatever speed each song wants — the app remembers the setting per song. The pitch can unlink from the tempo when you want the speed without the chipmunk. There is an EQ to lift the top end so the brightness sounds intended, a full effect rack, and full-screen visualizers that move with the music, which is what nightcore always deserved to look like. And the video export renders your track over a visualizer at 1080p, sized for YouTube, TikTok or a story, with the settings baked in.

It runs offline, needs no account, and the speed-and-pitch mechanics are free there too. Pro is one payment — forever. The 135% you settled on here is the same 135% there — same law, same readout, so the sound you found survives the move.
