Speed up music on Android,
right in the browser

No APK, because Chrome is enough

The Android route to a faster song usually starts in an app store: search, compare five lookalike apps, install one, grant it permissions, sit through its ads, discover the export is locked. This page removes the whole chain. Chrome on Android carries the same audio engine as desktop Chrome, and this tool runs on it directly.

Open the page, pick a file, move the slider — the decoding, the speed change, the reverb, and the export all happen on your phone's own processor, inside the tab. Nothing is sideloaded, nothing asks for storage permissions beyond the file you hand it, and nothing uploads, because there is no server involved in the audio at all. When you export, the MP3 or WAV lands in your Downloads like any other file, ready for WhatsApp, a video editor, or your file manager.

It works the same in Samsung Internet, Firefox for Android, and other modern mobile browsers. If a browser can play web audio — and current ones can — it can run this.

What it does and does not do

Speed from 50% to 200% with pitch linked (12 semitones per doubling), six reverb rooms with a mix control, loop, volume, waveform, free MP3/WAV export. It does not separate pitch from speed, add an equalizer, or export video — saying otherwise would be marketing, and this page does not do that either.

Files up to 50 MB, processed on the phone

The one hard limit is size: 50 MB per file. That fits nearly any single song at any normal quality — a 4-minute MP3 is usually under 12 MB, and even a 4-minute WAV stays around 40. What will not fit is an hour-long mix, and that is a fair trade for keeping everything on the device.

The limit exists because the whole file is held in the tab's memory while your phone processes it. A mid-range Android from the last several years handles a full song without effort; a very old phone may take a few extra seconds to decode. Either way the work is yours, not a server's — which is why the tool keeps working in airplane mode once the page has loaded.

There is a second, quieter benefit to the local design on a phone: it costs no mobile data beyond loading the page once. An upload converter moves your song up and the result back down over your connection — twice the file size in transfer for every single edit. Here the transfer is zero, so editing on a limited data plan, or on weak coverage, works exactly as well as editing on wifi.

A craft note for phone speakers

Judge the speed on headphones if you can. Phone speakers hide the low end, and a sped-up edit that sounds balanced on the speaker can turn out thin everywhere else. The common range for sped-up versions is 115% to 135% — a convention from fan edits, and a good place to stop moving the slider.

Start to finish on Android

About a minute, all inside Chrome.

1. Open this page in Chrome (or Samsung Internet, or Firefox).
2. Tap the file picker and choose a song from your phone — Downloads, internal storage, or an SD card, up to 50 MB.
3. Press play and move the speed slider. The sped-up preset starts you in the usual range; adjust in small steps until the voice is bright but still natural.
4. Optional: choose a reverb room and keep the mix low — sped-up edits rarely need much.
5. Export as MP3 or WAV. The file saves to Downloads; free exports add a short spoken note after the song ends, never over it, and any trimmer crops it off.

From Downloads to wherever the edit is going

On Android, the export's life after this page is short and easy: it is an ordinary file in Downloads, and the share sheet does the rest.

Sending it to a friend is one share away — messaging apps attach it like any audio file. Dropping it under a video works in every mobile video editor that can import audio from storage, which is most of them; pick WAV for that job if the editor will re-encode on export, so compression is applied once instead of twice. Moving it to an SD card or a computer is a file-manager copy like any other. Nothing about the export is special or locked to this page, which is the quiet advantage of receiving a real file instead of a link into somebody's cloud.

Three styles from one slider

The speed you choose is really a choice of style. Sped-up edits sit between 115% and 135% by convention — bright, urgent, usually dry. Slowed versions center near 85% and take reverb well; Hall at a low mix is the classic pairing. Nightcore pushes past normal sped-up territory toward 150%, where the raised pitch becomes the sound itself. All three are two controls on this page, not three separate apps to install and compare.

Version names and the master copy

Put the speed in the export's name before you forget it — "track 85 hall.mp3" reads better in a file list than five identical titles. And keep the original file somewhere the edits are not: the tool never changes your source, but an export slowed back to normal speed is not the original again. Two speed changes and two encodes always leave a mark. The source file is the master; every edit is a copy taken from it.

The iPhone side of this tool

You love sped-up music? There is a player for that.

Y2K Player is a music player for iPhone and iPad — Android users can hold us to it if we ever say otherwise: it is iOS only. It saves each song's speed and effect settings so the library always plays your versions, with playlists, video export at 1080p over visualizers, full offline use, and no account. Free to use. Pro is one payment — forever. On Android, this page in Chrome is the tool, and it stays free too.
