What is the SVG / DXF Path Offset & Kerf Compensation Tool?
Every laser beam and router bit removes a strip of material. Cut a 20 mm square on its outline and it ends up smaller than 20 mm while its holes end up larger — a problem for press fits, finger joints and anything that must fit together. Kerf compensation moves each outer outline outward and each hole inward by half the kerf so the finished part matches the drawing.
This tool applies that compensation, or a plain grow or shrink by any distance, to every closed path in an SVG or DXF, with a before/after preview and area change, and exports SVG or DXF. Open paths and text pass through unchanged. It all runs in your browser.
