Fractalize

Turn a picture into a fractal music video

Fractalize is Groovalizer's photo-to-fractal tool. Drop in a JPG, PNG or WebP, or take a camera snapshot, and the picture folds through one of 151 fractal patterns, 20 of them endless zooms, moving with your track's bass, mids and treble. Save it as a preset and export it at up to 4K on Pro. Checked 28 September 2026.

What Fractalize does

Your picture is the material. Each pattern is a map that decides, for every pixel on the screen, where in your picture to look: fold the plane into seven wedges and the picture becomes a rosette; run a Julia map first and it becomes filaments; push it down a log-polar tunnel and it flies at you forever. The map runs again every frame with the music in its constants, so the result is a moving scene rather than a filter.

The infinite zooms and deep fractals run the fractal’s own equation at every pixel and take their colour from your picture, so a Mandelbrot dive comes out in the colours of your photo.

GroupPatternsWhat it does to the picture
Infinite zoom20Dive forever into the Mandelbrot or Julia set, a Mandelbox or an Apollonian gasket. Each level repeats the last exactly, so the detail never runs out.
Deep fractals23The same fractals held in place and morphing with the song, plus Wada mirrors, the Zaslavsky web and the Hofstadter butterfly.
Folds20Mirror the picture into wedges and nest the copies: hexagonal, Apollonian, Sierpinski, Penrose, Mandelbox.
Lenses10Bend it through complex maps such as Mobius, Joukowski and the exponential, so straight edges curve.
Tilings16Repeat it across a moving grid: moire, quasicrystal, Voronoi cells, Truchet arcs.
3D shapes6Wrap it around a rendered solid: a torus, a knot, a Menger slab, a gyroid shell.
Classic fractals11Let Newton, Julia, Burning Ship and Phoenix iterations decide where each pixel looks.
Flows26Push it along a field: log-polar tunnels, Droste zooms, vortex twists, Clifford and De Jong attractors.
Projections4Map it onto a sphere, a floor in perspective, or a tesseract.
Curves15Bend it along rose curves, Cassini ovals, spirographs and Lissajous weaves.

151 patterns in 10 groups, counted from the tables the Studio ships. Most groups are named after the mathematics; you do not need to know it to use them.

Make one in five steps

  1. 1.Open Fractalize. Click Fractalize in the header, or open the Studio and pick it from the menu. It opens as a drawer beside the stage with a sample picture already loaded, so the patterns are never blank tiles.
  2. 2.Pick a picture. Drop in a JPG, PNG or WebP, or take a snapshot with your camera. The picture is measured on your device; if it is flat or dim, a colour and contrast boost switches on to help, and you can turn it off.
  3. 3.Choose a pattern. Click any of the 151 patterns and it plays on the stage at once, with your picture inside it. They sit in 10 groups, from endless zooms to 3D shapes. Click the playing pattern again to open its settings.
  4. 4.Tune it. Customise holds the settings for whatever is playing, and each change dissolves in over about a second. On the folds, lenses and the other families, Tempo sets how fast the pattern morphs (slow reads best), Scale moves it in or out, Show original mixes your picture back in, and Symmetry mirrors it into wedges. The zooms and deep fractals have their own set: which part of your picture paints them, a second picture woven in, the shape and how hard the music pushes it, symmetry, and a finish from glow to vignette.
  5. 5.Save and export. Save to my presets keeps it in your library under Mine. From there it plays with any track, takes a section on the timeline, and exports as MP4 at up to 4K on Pro.

Your picture and your account

The picture is prepared on your device: resized to at most 2048 pixels on its long edge, boosted if you asked, and written straight into the running engine. Signed out, that is where it stays, and a pattern you save keeps working in this browser.

Signed in, the prepared copy is saved to your account under a name made from its content, so the same picture is stored once no matter how many patterns you save with it, and a saved preset opens with its picture on any device you sign in from.

Pictures that work

Colour and contrast survive folding; fine detail does not. A bold poster, a saturated sunset, a face against a plain wall or a piece of your own artwork gives the patterns edges to work with. A dim phone photo turns to mud, which is why the panel measures colourfulness, saturation and contrast when a picture lands and switches on the boost for weak ones.

Faces and text become geometry. If you want the subject to stay recognisable, raise Show original and let the fractal frame it instead of replacing it.

Free to play, Pro to export

Everything up to the export is free: the picture, the 151 patterns, the settings, playing it with your track or a microphone, and saving it to your presets. Turning it into a file takes Pro, $14.99 a month or $144 a year, with the first 7 days free: MP4 (WebM in Firefox) at 30 or 60 frames per second, in 16:9, 9:16 or 1:1, up to 4K.

Rendering happens on your machine, so a long video takes as long as your hardware takes.

Where it goes next

A saved Fractalize preset lives under Mine with everything else you have saved, so it behaves like any other preset: give it the chorus on the timeline and a calmer scene the verse, play it from a microphone at a show, or export the whole song with it.

Album art through a Droste zoom makes a release visual that is unmistakably yours. A band photo through a seven-fold mirror makes a tour poster that moves.

Frequently asked questions

Is Fractalize free?

Yes. Opening it, loading a picture, playing any of the 151 patterns with your music and saving the result to your presets are all free. Exporting a video takes Pro, $14.99 a month or $144 a year, with the first 7 days free.

Does my photo get uploaded?

Signed out, no: the picture is prepared in your browser and stays there. Signed in, the prepared copy, a JPEG no larger than 2048 pixels on its long edge, is saved to your account under a content name, so a saved preset keeps its own picture on any device you sign in from.

Which files work?

Any image your browser can open, usually a JPG, PNG or WebP, or a snapshot taken with your camera from inside the panel. Videos and other files are refused.

Does the fractal react to the music?

Yes. Each pattern is a preset that reads bass, mids and treble every frame, so the fold, the zoom and the colour drift move with the track. The pattern also has its own slow clock, set by the Tempo slider, and the music moves it on top of that. On the zooms and deep fractals you also choose whether it follows the bass, the mids, the highs or all three.

Can I use it on the timeline or live?

A saved Fractalize preset is an ordinary preset in your library. It shows up under Mine with your other presets, so it can take one section of a song on the timeline, play from a microphone, or export.
