Chopped and screwed is a remix style built on two moves: slowing a track's tempo and pitch down together (the "screw"), and cutting, stuttering, and repeating sections of it (the "chop"). It came out of Houston's hip-hop scene in the early 1990s, and the syrupy, woozy feel it gives a track has stuck around in mixtapes, DJ sets, and short-form video edits ever since.
You don't need a studio or a paid DAW to make one. This guide walks through doing it entirely in your browser with Screwlab: upload a track, screw it, chop it, preview it, and record your take. Everything below is free to try, and we'll call out the one step (downloading a clean export) that needs a Screwlab Pro account.
What you'll need
- An audio file you have the rights to use (your own recording, a royalty-free track, or a stem you're cleared to remix)
- A modern browser — no plugins or installs
- About 10 minutes
Step by step
-
1. Upload your track
Open the Screwlab player and upload the audio file you want to work with. You can try this without creating an account.
-
2. Check the BPM
Screwlab's AI-assisted analysis estimates the track's BPM automatically, so you have a starting tempo before you touch anything.
-
3. Apply a screw preset
Slow the tempo and pitch down together with a screw preset, or dial in your own speed. Most chopped and screwed mixes land around 60–75% of the original tempo — more on picking a speed below.
-
4. Chop the track
Use the suggested chop points as a starting place, or set your own, to stutter, repeat, and cut sections for that signature chopped effect. Chopping on a bar line or a natural pause in the vocal usually sounds cleanest.
-
5. Preview and fine-tune
Play your edit back right in the player. Nudge the screw speed and adjust chop points until the mix sits right — this is the step worth spending the most time on.
-
6. Record your take
Record your live performance directly in the browser. Recording and in-player playback are free, and a free account keeps your track library and queue for next time.
-
7. Export clean audio
To download a clean MP3 for posting to TikTok or Reels or dropping into a set, upgrade to Screwlab Pro. Recording and playback stay free either way.
Tips for a better chopped and screwed mix
- Start slower than you think, then back off. It's easier to speed a mix back up a little than to notice too late that it dragged.
- Chop on the beat, not in the middle of a word. Cutting mid-syllable is the fastest way to make a chop sound like a mistake instead of a style choice.
- Vocal-forward tracks screw well. A clear, present vocal holds up better at a slower tempo than a busy, layered mix.
- Leave room for the low end. Slowing a track down thickens the bass; don't chop so aggressively that it turns muddy.
Good to know: your track library and queue are stored in your browser on your device. Audio is never uploaded anywhere else, and clearing site data or switching browsers or devices will remove them.
Frequently asked questions
What does "screwed and chopped" mean?
It's a remix style that slows a track's tempo and pitch down together (the "screw") and edits in stutters, repeats, and cuts at points in the song (the "chop"). It originated in Houston hip-hop in the early 1990s.
How slow should I screw a track?
Most chopped and screwed mixes run at roughly 60–75% of the original tempo. Start with a screw preset and nudge the speed until the vocals and bass still sit well together — going too slow can make a track lose its groove.
Do I need to download software to chop and screw music?
No. Screwlab runs entirely in your browser. There's nothing to install, and you can try the player without creating an account.
Is Screwlab free to use?
Yes. Uploading, BPM analysis, screwing, chopping, previewing, and recording in the browser are all free. A free account also saves your track library and queue. Screwlab Pro adds clean MP3 downloads.
Can I download my chopped and screwed mix?
You can record and play back your mix for free in the browser. Downloading a clean MP3 file — for posting to TikTok or Reels, or playing in a set — requires Screwlab Pro.
