Image to Laser Engraving Converter
Free online tool to convert images for laser engraving machines. High contrast 1-bit black and white output with dithering. Supports invert for dark materials. Works with xTool, Glowforge, and LightBurn.
The Image to Laser Engraving Converter transforms your photographs into machine-ready files optimized for laser engraving and cutting. Whether you use a CO2 laser, diode laser, or fiber laser, our tool produces the high-contrast output your machine needs for clean, professional results.
Understanding Laser Engraving Requirements
Laser engravers work best with 1-bit (pure black and white) images. Grayscale photographs need to be converted into patterns the laser can interpret — either pure black/white edges or dithered dot patterns that simulate shading through varying dot density. Our tool offers both approaches.
Two Processing Modes
The default Blueprint mode uses Canny edge detection to extract clean, sharp edges from your photographs. This is ideal for engraving outlines of buildings, logos, text, and geometric designs. Toggle the Dithering button to switch to Floyd-Steinberg dithering, which converts your photo into a dot pattern that preserves tonal gradations — perfect for photographic portraits and detailed artwork on wood, leather, or acrylic.
Invert for Dark Materials
When engraving on dark-colored materials like black anodized aluminum or dark wood, you need inverted output (white lines on black background). Our Invert toggle instantly flips the color scheme.
High-DPI Export
The High-DPI download option re-processes your image at up to 2400px resolution, ensuring your engraving has maximum detail even on large workpieces. Compatible with xTool, Glowforge, Ortur, Atomstack, and LightBurn software.
All processing runs locally in your browser — your designs never leave your computer. Free, instant, no sign-up required.
