Scans your SVG for issues that cause bad cuts - duplicate lines, open paths, stray geometry, and features too small for your kerf. Safe problems are removed automatically; ambiguous ones are flagged for your review.
Colors found in this file and what operation each maps to based on your machine profile.
These are almost certainly accidents. Safe to remove automatically.
These might be intentional - open paths could be score lines, small elements could be detail work. Flag them in the file and review in LightBurn.
Detects intentional geometry that may be too small for the laser to produce cleanly - holes that will burn closed, slots narrower than the beam. These are warnings, not errors. Fix in your design tool before cutting.
Finds thin bridges within complex shapes - when two non-adjacent segments of the same closed path come within the threshold, that section is fragile and may snap during or after cutting. Straight-segment paths only; curved shapes are not analyzed.
Flagged paths are highlighted in cyan. Open in Illustrator or LightBurn to locate them.
Most failed laser jobs trace back to a few quiet file problems: a path that looks closed but is not, a stray point the laser pauses on, a feature too thin to survive the cut, or two lines stacked on top of each other that burn twice. None of these are obvious on screen, and all of them cost you material and time.
Drop your SVG in above and the checker scans it in your browser and reports what it finds, so you fix it before the laser runs, not after. Nothing is uploaded.
Open paths. Shapes that are not truly closed and will not cut as a single outline.
Stray points and tiny features. Specks and details too small to cut cleanly at your settings.
Duplicate and overlapping lines. Stacked cut lines that double-burn edges and slow the job.
Yes, and it runs entirely in your browser. Your file is never uploaded.
No. It only reports issues. Fix them in your design software, or use the other sparq.tools to adjust the file.
