Laser Cut File Checker

It reads your file the way the laser will, which is not the way your design software showed it to you.

Nothing is uploaded. It runs in your browser, so your files never leave your machine — and it stays free.

Part of the Maker Toolkit: fourteen tools that share one shop profile and one product list, so what you set up here is already known everywhere else.

How it works

Laser Cut File Checker, step by step

It reads your SVG the way a laser will. Open cut paths, shapes stacked on top of each other, text that was never outlined, colours that map to no operation at all. You get a score out of 100, a plain-English fix list, and a one-click correction for the safe ones.

  1. Upload your SVGThe file you were about to send to the machine.
  2. Read the findingsEach one says what it means, and shows you which objects are at fault.
  3. Correct the safe issuesClose gaps, drop duplicates, strip scripts. You choose which.
  4. DownloadThe corrected file, or the report if you’d rather fix it at the source.

Why it is built this way

The decisions behind it

Catches doubled cutsTwo identical shapes stacked up means the laser burns the same line twice. Scorched edges, doubled run time, and a fire risk on thin stock.
Catches unoutlined textIf the machine doesn’t have your font it quietly substitutes another one, or drops the text altogether.
Says what it meansNot a list of error codes. Every finding tells you what will actually happen to your material.

Questions

Laser Cut File Checker — common questions

What problems does a laser file checker catch?

Cut paths that do not quite close, duplicate shapes stacked on each other so the laser burns the same line twice, text that was never converted to outlines, embedded raster images, zero-length stray objects, hairline-versus-thick stroke conflicts, and colours that map to no machine operation at all.

Why did my laser cut the same line twice?

Two identical shapes sitting on top of each other, usually from a copy-paste or a duplicated layer. You cannot see it on screen because they overlap exactly. The result is a scorched edge, double the run time, and a genuine fire risk on thin stock. This is the single most common finding.

Why does my text disappear or change font when I cut?

Because it is still live text rather than outlines. The machine does not have your font, so it substitutes another or drops the text entirely. Convert to outlines before exporting, and this tool will tell you when you have forgotten.

Does it fix the problems or just report them?

Both, and it separates them deliberately. It corrects the safe ones in place, closing small gaps, dropping exact duplicates, stripping scripts. Anything where the right fix depends on your intent is reported for you to fix at the source.
