Frequently asked questions

Lazrit is a web app that turns raster artwork into laser-cut-ready SVG files. It runs topology validation, generates auto-bridges for floating islands, and separates cut and engrave layers — all in one workflow.

Makers, Etsy sellers, sign shops, hobbyists, designers, and educational makerspaces. Anyone who runs artwork through a laser cutter and is tired of failed cuts from bridge problems and bad topology.

No. Lazrit is a web app. Sign in with Google in your browser and you're working.

Inkscape is a general-purpose vector editor. Lazrit is built specifically for laser-cut file prep — topology validation, auto-bridges, material-aware defaults. Inkscape can do these things if you know what you're doing; Lazrit does them by default.

There are 3 free exports forever — enough to ship three real projects. Paid plans start at $19/mo for 100 exports/month.

A bridge is a tiny strip of uncut material that holds a floating island (like the inside of an 'O') to the rest of the design. Without bridges, those islands fall onto the cutting mat instead of staying part of your sign or stencil. See the dedicated learn article on bridges.

It parses every closed path in your design, builds a connectivity graph, and identifies any closed region that isn't connected to the main piece. Every disconnected region is an island candidate for an auto-bridge.

Yes — the reversed-plaque mode treats letters as voids and adds bridges to each closed counter. See the reversed-out-text tool page for the deep dive.

Yes — auto-bridge runs on every island, including logo interiors. You can accept, drag, or remove each bridge before exporting.

The workspace renders flagged areas in a warning color and shows a count. Hover any flagged element for the exact measurement and recommendation.

Not yet. Kerf compensation is on the roadmap. The exported SVG matches your design; the laser will remove its kerf inside the path. For tight-fit parts you'll need to compensate manually in your design.

It depends on the material. Wood and acrylic: 1 mm. Paper/cardstock: 0.5 mm. Mylar: 0.4 mm. Metal: 1.5 mm. You can override the threshold in the workspace.

Yes — drag any auto-proposed bridge to a new location, delete it, or add manual bridges. The validation re-runs as you edit.

Wood, acrylic, MDF, mylar, metal, paper, and cardstock — each with its own minimum detail, minimum bridge width, and default thickness.

Use the 'custom' material option and set the thickness, minimum bridge, and minimum detail to whatever you need.

No — those are tuned in your laser software (LightBurn, XCS, Glowforge app). Lazrit produces the file; you tune the machine.

Each material has a dedicated page covering common failure modes, recommended settings, and tips. See /materials.

Both work with the paper profile as a starting point. Leather tends to char more — slow the cut.

No. Photo engraving (dithered or halftone burns from photos) is outside Lazrit's scope. We focus on vector cut + vector engrave workflows.

PNG, JPG, and SVG. Raster uploads go through the vectorizer; SVG uploads go directly to topology validation.

SVG and native LightBurn .lbrn2 project files. The .lbrn2 export carries cut/engrave layer assignments and default cut settings into LightBurn directly.

Yes. The SVG output is plain, standard SVG with named layers for cut and engrave. Every major laser app reads it cleanly.

No. The output is standard SVG — no embedded scripts, no Lazrit-specific elements.

Yes. Each export uses one export from your quota — 3 lifetime on Free, monthly on paid plans.

If your laser software reads SVG, yes. That includes LightBurn, Glowforge, xTool XCS, LaserGRBL, EZCAD, RDWorks, and most others.

Yes — the SVG output is machine-agnostic. Fiber-specific settings (pierce points, beam compensation) live in your fiber slicer.

Lazrit is a web app — runs in any modern browser on any OS.

No native desktop app today. The web app is the only client.

If they use any commercial laser app from the last 5 years, yes.

Three lifetime exports free. Paid plans start at $19/mo (Starter, 100 exports + 50 AI credits), $49/mo (Designer, 500 exports + 250 credits), $99/mo (Pro, 1,000 exports + 600 credits).

Yes — manage your subscription via the Stripe customer portal linked from your Account page.

No — sign in with Google and you get 3 lifetime exports without a card.

On Free: upgrade or wait. On paid plans: wait until the month rolls over, or upgrade to a higher plan. No throttling, no hidden charges.

Yes — annual saves roughly 17% (two months free). Six-month plans save roughly 13%.

Yes — uploads are stored to your library so you can resume projects. Delete a project to remove the upload.

No. Your uploads are not used as training data.

Yes — email us and we'll remove your account and all associated uploads.
