The whole effect is computed on your own GPU via WebGPU. Your photos stay on your device — nothing is ever sent to a server.
Turn your photos into infinite spirals
PhotoSpiralysis applies the Droste/log-spiral effect to your photos — the recursive "picture within a picture" look, rendered in real time as you adjust it. Runs entirely in your browser: your photos are never uploaded anywhere.

Why PhotoSpiralysis
Real-time preview
Drag a slider and watch the spiral respond instantly. No waiting, no "render preview" button — just live feedback as you tune the effect.
Precise masking
Shape exactly what feeds the spiral with a circle, a freeform polygon, or a color key — each with a soft, feathered edge.
Full-resolution export
Export your result at your photo's native resolution, rendered on the GPU — no more waiting minutes for a high-res save.
How it works
- Upload a photo — it never leaves your browser.
- Adjust zoom, rotation, and masking with live preview.
- Export a full-resolution PNG in seconds.
