An SVG is not a stitch file. Machines read formats like DST or PES, which you make in digitising software. What this tool does is the step before: it turns a flat logo or drawing into a small number of clean colour shapes, which are much easier to digitise than a pixel image with hundreds of near-identical colours.

How to do it
Use a flat logo or drawing with few colours. Gradients and photos will not digitise well in any tool.
Drop it above and keep Mode on Colour. Set Colours to the number of thread colours you want to end up with, usually 3 to 8.
Check the preview for stray fragments. Fewer, larger shapes stitch better than many small ones.
Download the SVG.
Open it in your digitising software (for example Ink/Stitch in Inkscape, or the import tool in your machine maker's software) and convert the shapes to stitch types there.
Small details do not stitch
Thread has a width. Lines thinner than about 1 mm and tiny text usually fill in. Simplify the artwork before you trace it.
Match colours to your thread chart
The traced colours are the nearest flat colours in the image. Re-map them to your actual thread shades in the digitising software.
Expect to edit
A trace gives you shapes, not stitch direction, density or underlay. Those choices are part of digitising and need a person.
Questions
Does this make an embroidery file?
No. It makes an SVG of colour shapes. You still convert it to DST, PES or similar in embroidery software.
How many colours should I use?
As many as the thread colours you plan to use. Fewer is cleaner. Start with 4 and raise it only if a needed colour is missing.
Why does my logo come out with extra bits?
Edge blur between two colours creates thin in-between shapes. This tool merges many of them, but a sharper source image helps more.
Is my image kept?
No. Tracing happens on your device.
What does it cost?
Three free downloads a day, then $7.99 a month for unlimited, or $6.99 for 20 images.
