Questions about the checker

Yes. Checking, fixing and downloading are free, with no sign-up.

No. The checker runs in your web browser, on your own computer. Your file is never sent to us or anyone else.

SVG files and DXF files (the normal text kind). For a PDF, an Adobe Illustrator file or a LightBurn project, save or export it as SVG or DXF first. Binary DXF files are not supported yet.

It removes doubled lines and shapes drawn twice, removes edges that touching shapes share (for lasers), joins broken outlines, closes shapes whose ends almost meet, and removes stray dots, tiny pieces and pictures. It never moves or redraws your design. Typed text and shapes with big gaps are left for you, with instructions.

Any laser or plasma setup that takes SVG or DXF: for example LightBurn, xTool Creative Space and xTool Studio, the Glowforge app, SheetCAM and Fusion for plasma tables, and online metal-cutting services. It checks files made in Inkscape, Illustrator, Affinity Designer, CorelDRAW, Fusion and other CAD programs.

Yes. Line colors are kept in the SVG, so your laser software still sorts them into layers. In the DXF, each color goes on its own layer.

Yes. Filled shapes stay filled in the SVG, so an engrave stays an engrave. Pictures (bitmaps) are taken out, because they cannot be cut.

A plain R12 DXF with the units written in the file (millimeters or inches, your choice), plain polylines and circles, and no splines. That is the kind plasma software and metal shops read most reliably.

Close gaps up to: ends closer than this are joined (default 0.5 mm). Remove pieces smaller than: closed shapes smaller than this across, and loose bits shorter than this, are removed (default 0.5 mm). Lower them for very fine jewelry work.

Not yet. This tool checks and fixes vector files (SVG and DXF). Photo to cut file is planned for later.
