FAQ
Which formats can I download for spiral art?
Choose PNG, JPEG, WebP, or SVG. Raster output is drawn on a canvas; SVG contains the variable-width line segments used for the spiral.
Can I change the spiral colors and detail?
Yes. Set 30-400 turns, choose Fine, Medium, or Bold thickness, and pick line and background colors. Brightness, Contrast, and Invert adjust the tonal mapping.
Why is my photo cropped?
The tool crops the image to a centered square before generating the spiral. Crop your source photo first if you need a different subject position.
Is the SVG a single continuous vector path?
No. The SVG consists of individual line segments with varying stroke widths. Check whether your plotting or cutting software supports that representation.
Is my photo sent to a server?
No. The selected photo is decoded and processed locally in the browser.
