Free Online DJ Mixer: Two Decks, Hot Cues and Loops in Your Browser

Load a track on each deck, set your cues, and mix. ClipCraft's DJ tool is a free online DJ mixer that runs entirely in your browser: two decks with real waveforms and spinning platters, eight performance pads per side, a 3-band EQ on every channel, and an equal-power crossfader in the middle. Nothing installs and nothing uploads. Your files decode locally through Web Audio and never touch a server, so there's no upload wait even on a big WAV. Here's the whole surface, plus the version of these decks that lives inside our DAW and can record your set.

What's on each deck

The top of each deck is a full-track waveform. The played portion lights up in the deck's color, a white line marks the playhead, and you can click or drag anywhere on it to seek. Your hot cues appear as numbered ticks along the top, and an active loop draws an amber region, so you always know where your markers live inside the song.

Below that sits the jog wheel. It spins at two seconds per revolution at normal speed, which sounds like trivia until you use it: drag the platter while paused and it scrubs at that same rate, drag it while playing and you get a scratch-style nudge, and the mouse wheel gives a tiny bump for beatmatching by ear.

The tempo slider defaults to a tight ±8% range. Click the range button and it steps to ±16% and then ±25% if you want bigger swings. The two Bend buttons are momentary ±3% pushes, exactly what you need to slide a slightly-early beat back into phase without touching the main slider. Cue works the classic DJ way: first press sets the point at the playhead, and pressing it while the track plays jumps back and holds until you let go.

Hot cues, loops, beat jump and a sampler

Each deck has eight pads with four modes. Hot Cue is the default: press an empty pad and it stores the current playhead position, press it again and you jump there. In my screenshot above I dropped three cues at 0:08.3, 0:20.4 and 0:32.9, which is enough to skip an intro, hit the first drop, and grab the breakdown on demand. Loop mode gives you beat-length loops from 1/4 up to 32 beats, calculated from the deck's BPM. Jump mode moves the playhead by 1, 2, 4 or 8 beats in either direction. Sampler mode turns the pads into one-shot triggers: click an empty pad, pick a sound off your drive, and it fires through the channel fader whenever you hit it.

There's a Quantize toggle in the header, and I'd leave it on. With a BPM set, it snaps cue jumps, loops and beat jumps to the beat grid, which turns sloppy pad mashing into something that stays on time.

The mixer: EQ, filters and an equal-power crossfader

The center section is a proper two-channel mixer. Each channel gets a gain knob (up to 150%), High, Mid and Low EQ knobs with a range of -24 to +12 dB, a sweep filter, a vertical fader, and a live VU meter. The EQ's -24 dB floor is deep enough to effectively kill a band, so the standard bass-swap blend works the way it does on hardware: pull the incoming track's lows all the way down, bring the fader up, then trade the bass at the phrase change.

The filter is one knob doing two jobs. Turn it left and a low-pass closes down toward 200 Hz; turn it right and a high-pass rises toward 8 kHz; center is off, and the knob turns amber whenever it's active so you can't forget it. The crossfader below is equal-power, meaning the combined energy stays flat as you move through the middle instead of dipping. And there's a limiter fixed on the master bus, so pushing both channels hot gets squashed rather than clipped.

Mixing your first transition

1. Open the DJ tool and load a track on each deck. The Load button or a straight file drop both work, and it takes MP3, WAV, OGG and M4A.
2. Give both decks a BPM. Type it into the field if you know it, or hit Tap on the beat four times and it calculates one for you.
3. Press Sync on the incoming deck. It matches tempo to the other side.
4. Set a hot cue on the incoming track where you want it to enter.
5. Kill the incoming lows, fire the cue on a phrase boundary, and walk the crossfader over while you swap the bass.

Almost everything here is on the keyboard too. Keys 1 through 8 fire deck A's pads and Shift+1 through 8 fire deck B's, W and P toggle play on each side, the arrow keys nudge the crossfader, and Shift+C snaps it back to center. The ⌨ Shortcuts button in the header lists the full map.

Is this online DJ mixer really free?

Yes, with one honest caveat. All the audio work happens on your own machine, so there's no compute bill for us to pass on and no token cost to you. A session does cost one tool use, charged when you load your first deck. The free plan includes one tool use a month, and the $1.99 Saver plan raises that to five. That's the entire pricing story. Since your tracks never upload, there's also no file size anxiety and no waiting on a progress bar. A free account is all you need to start mixing.

The same decks live inside SoundCraft

This is the part I'd actually lead with if you make music. The identical two-deck mixer is also an instrument inside SoundCraft, our free browser DAW (here's the full tour of SoundCraftif it's new to you). Embedded there, the decks open in a floating window you can drag anywhere, resize, pop out into its own OS window on a second monitor, or tear off by dragging past the browser edge. Three things change when the decks run inside the DAW:

• Every control becomes MIDI-mappable. That's 40 targets across both decks: all ten mixer knobs, the tempo sliders, channel faders, crossfader, master, play, cue, stop and sync, plus all sixteen pads. Map a cheap MIDI controller once and you're mixing on physical knobs.
• A ⏺ Record set button sits in the window header. One press creates a "DJ Take" channel, arms it, and rolls the transport. Stop, and your whole mix is sitting on the timeline as a normal audio clip you can trim, master and export.
• Decks can pull audio from your project. The Channel picker next to Load renders any other channel's timeline through its effects and drops the result on the deck, so you can DJ with stems from the song you're producing.

Record a set you like and you can post it straight to the ClipCraft music feedfrom SoundCraft's export dialog. And if what you really wanted was a permanently sped-up edit of one song rather than a live mix, that's a different tool: see the nightcore guide.

What it doesn't do yet

A few honest gaps. There's no automatic BPM detection, so you type the tempo or tap it in (Tap wants at least four taps before it locks). Key Lock is visible but disabled, because real key lock needs time-stretching; for now, big tempo moves shift the pitch like vinyl. The 🎧 PFL button is visual-only since browsers make routing a second headphone output awkward. Flux mode is an armed light without the slip behavior behind it yet. And hot cues and loops are session-local: close the tab and they're gone, so this is a performance surface, not a library manager with saved crates.

None of those stopped me from doing a clean two-track blend in the first five minutes. For practicing transitions, testing which of your own tracks mix together, or playing a set from a laptop with zero installs, it covers the job. Sign up free, load two songs you know well, and try the bass-swap blend from the steps above.
