Choose a picture, control the dot pattern, size the finished design, then export an SVG for your cutter. Your source image stays on your device.

Start with a high contrast image. The controls below turn sampled dark or light areas into circles with physical millimeter dimensions.

Start with a simple silhouette or bold line drawing.
Preview and measurements are planning aids. Import the SVG at its stated size and make a small test cut before using production material.
A reliable first cut
SS labels are ranges, not exact universal measurements. Measure the stones you actually have or use the supplier's specification. A nominal SS10 stone is often around 2.7 to 2.9 mm, but batch and brand differences matter.
Compare size rangesThe cut hole usually needs to be slightly larger than the stone so it brushes in without falling through. Start with a modest allowance, export the calibration strip, and test the exact flock and blade combination.
Spacing protects the small bridges of template material between holes. Dense dots may look smooth on screen but tear or merge on the cutter. Increase the gap when small bridges lift during weeding.
Before you export
The estimated stone count is the number of circles in the exported SVG. It helps you compare versions and prepare material, but it is not a purchasing guarantee. Keep extra stones for loss, defects, and changes during brushing.
If two settings create a similar silhouette, choose the one with fewer stones and stronger gaps first. A readable low density design is often easier to cut, weed, brush, and press.
File and cutter checklist
Questions before cutting
No. The file is decoded with browser APIs, processed on a local canvas, and converted into SVG text on your device. Plausible records coarse actions such as an export, not filenames or image contents.
Use a simple, high contrast shape with a clear silhouette. Detailed photographs create noisy dot patterns. Crop first, then adjust threshold and invert until the main shape reads at normal viewing distance.
The export is a standard circle based SVG. Import behavior and physical results vary by software version, machine, blade, mat, and material, so verify document dimensions and run a small test cut.
The selected hole diameter is too large for the grid pitch, or the physical cutter is widening the holes. Increase the gap, reduce cut compensation, or use a larger finished design.
No. It is a narrow conversion and calibration tool. Use vector software when you need manual path editing, mixed stone sizes, complex lettering, or production nesting.
Method notes
The generator samples a regular grid from a resized grayscale copy of your image. A dot is placed when the sampled tone crosses your threshold. This makes the result predictable and easy to cut, but it does not trace every image edge or optimize stone placement by hand.
Dimensions and counts come from the chosen grid pitch. They are planning estimates. Real stone diameter, template material, blade offset, adhesive, transfer tape, and press conditions introduce tolerances that a browser cannot measure.
