Laser Engraving Image Converter. Free
The fastest way to prep an image for laser engraving. Browser-based, AI-tuned, free to try.
StencilCut is a free laser engraving image converter that runs in your browser. Upload any image (PNG, JPG, or WEBP), pick the material you are engraving on, and the AI produces a tonal engrave-ready file in seconds. The output is a transparent PNG (drops straight into LightBurn or Glowforge as an Image layer) plus an SVG wrapper. Tuned per material for wood, leather, slate, acrylic, glass, and anodized aluminum.
Material aware
One toggle per material so the contrast curve matches what your laser is actually burning into.
Subject isolation
Background removal first so only the subject burns. no muddy shadows from a busy room.
PNG + SVG download
Transparent PNG for image-layer engraving, SVG for vector-only workflows.
Advanced controls
Override threshold, blur, dilation, kerf, and the engraving style anytime in Advanced builder.

Why a dedicated converter beats Photoshop curves
You can hand-tune brightness, contrast, and a custom curve in Photoshop or GIMP and get an engraving file that looks fine. but it takes 10 minutes per image and the result depends on your patience. A purpose-built laser engraving image converter encodes the material-specific curves once, applies them automatically, and ships the result in 30 seconds.
What the converter does behind the scenes
Subject detection (segments the foreground), background removal, contrast normalization, material-tuned tonal mapping, optional stylization (pencil, hatching, etching, etc.), edge sharpening, and a preflight pass that flags too-thin areas. The whole pipeline runs server-side and returns the result inline.
Ready for every laser cutter that engraves
LightBurn, Glowforge App and Premium, xTool Creative Space, RDWorks, LaserGRBL. all read the output PNG or SVG natively. No re-export, no plugins, no manual cleanup.

Open the Converter →Frequently Asked Questions
Is the laser engraving image converter free?
Yes. 5 free designs to start, no card. Credit packs available from $2.99 for higher volume.
How is this better than a regular image-to-vector tool?
Vector tools convert pixels to paths. that is for cutting. An engraving converter maps tones to scorch depth. that is for surface burning. Different problem, different math.
Can I use my own contrast curve?
Yes. Advanced builder exposes threshold, blur, dilation, and bridge knobs. Default presets work for 90% of users.
Does it support color separation for two-pass engraving?
Not yet. Output is single-channel tonal. Pull request and feature requests welcome.
Will it integrate with my laser pipeline?
Yes. Drop the PNG into LightBurn as an Image layer or import the SVG and assign it as engrave. The DXF version (cut layer companion) imports into LightBurn, RDWorks, Fusion 360, and AutoCAD.
