Drop in a song, a podcast clip or a DJ mix. BiepBop listens frame by frame and animates your visuals to the music — then renders a real .mp4 for TikTok, Reels, YouTube or Spotify Canvas, right on your own computer.
MP3, WAV or anything else your browser can decode. It is analyzed on your own device into bass, mid, treble and the beat — nothing is uploaded.
Start from a template or stack your own layers, then link any band, the beat or a custom Hz range to size, glow, rotation or opacity. It all plays live while you tune it.
Choose TikTok, Reels, YouTube, Spotify Canvas or a custom size and render a watermark-free .mp4 — up to 4K at 60 fps, with your audio muxed in.
These are not videos: every tile is a real BiepBop template drawn live by the engine in this tab. Press play to hear one react to the demo track. 16 templates ship with the editor.
The arrow on a tile opens the editor with that template. Every template is also in the editor's Template menu at the top of the Layers panel (on a phone: Add → template). Applying one backs up your current project first.
Every preset, template and control is aimed at one job: getting audio in front of people in the formats the feeds actually play.
Release visuals without learning motion design. One project gives you the YouTube visualizer, the vertical teaser and the cover loop.
A Spotify Canvas that hits on the track's own kick, and a look you can reuse for every release in the campaign.
Audiograms that give a clip a reason to stop the scroll: cover art, a waveform that follows the voice, captions and a progress bar.
Full-width spectrum bars, pulse rings and big titles for mixes and set announcements. Render in the background while you keep editing.
44 visualizer styles driven straight from the live spectrum — bars, waveform, radial, tunnel, galaxy and more. Or design your own from a shape, even your logo's outline.
Route bass, mid, treble, the full mix or the beat — or a custom Hz range — to intensity, glow, rotation, position or opacity. Add as many named analyzers as you like.
Stack 14 layer types — visuals, shaders, text, lyrics, images. Blend modes, masks and per-layer opacity, composited every frame.
Animate over time on a zoomable timeline, or let any parameter ride the audio. Smooth curves, no timeline tetris.
Give any layer an entrance, an exit and a loop — fade, slide, pop, wipe, typewriter, float, heartbeat on the beat. Title reveal and other combos in one click.
Drop audio, images, GIFs, videos or a project file anywhere in the editor, or paste an image. Animated backgrounds, Ken Burns stills and built-in royalty-free loops included.
Add BiepBop to your desktop or home screen. It opens straight into the studio and keeps working offline — your projects stay in this browser.
20 stackable post-FX plus real WebGL shaders — bloom, glitch, kaleidoscope, fish-eye, wave / ripple and more.
WebCodecs renders H.264 on your own machine, up to 60 fps and 4K. Every aspect ratio, several in one click, your audio muxed back in, no watermark, no upload.
Set up the project at any size — including a free custom width × height. BiepBop re-frames the composition and renders each aspect ratio on your own machine.
It stays on your device. Your audio is encoded to AAC (Opus fallback) and muxed alongside the video — the whole render runs locally, nothing is uploaded.
BiepBop does all of its work inside your browser tab. That one decision is where every other promise on this page comes from.
Your audio never leaves your device. Decoding, analysis and rendering run in the browser tab — safe for unreleased tracks.
Every export is clean, at every resolution. There is no paid tier that unlocks quality.
Open the page and start — or install it as an app that works offline. Projects, presets and media autosave in your own browser.
H.264 .mp4 (or WebM) up to 4K and 60 fps, with your audio encoded to AAC and muxed in.
Each export renders in a background queue from its own copy of the project, so you can start your next video right away. A badge tells you when a file is ready.
96 frequency bins from 30 Hz to 16 kHz, read every frame. Bass, mid, treble, the beat or your own Hz range can drive anything.

No tiers, no trial, no credit card. Everything below is included for everyone.
