SVG Closed Path Checker

Check whether all paths in an SVG file are closed. Closed paths are required for laser cutting and CNC routing to produce complete cuts.

Why Closed Paths Are Critical for Laser Cutting

A laser cutter follows the vector paths in your SVG file exactly. If a path is open (the start and end points don't meet), the laser will not complete the cut — you'll end up with a profile that is still attached to the material at the gap point. This checker identifies all open paths so you can fix them before cutting.

Verify that every cut profile is closed before sending a job to the laser cutter.

Frequently Asked Questions

What causes open paths in SVG?
Open paths are common when converting from other formats, tracing bitmaps, or using boolean operations in design tools. They are also caused by missing Z commands in SVG path data.
