Turn a photo or drawing into a grayscale relief height map for CNC carving, 3D printing and laser depth engraving.
PNG · JPG · WEBP · HEIC · up to 20 MB
Turn a photo or drawing into a smooth grayscale height map for CNC carving, 3D printing and laser depth engraving.
Use a photo or drawing with a clear subject, up to 20 MB.
Choose the relief depth, smoothing and fine detail, and invert if your machine expects black as high.
Download a 16-bit-style PNG, BMP or an STL mesh for your CNC, 3D printer or laser.

The 3D Relief Generator estimates the shape of the subject in a picture and writes it as a height map: white is high, black is low. CNC software, 3D printers and lasers with depth engraving turn that grayscale into real relief.
Unlike a plain grayscale conversion, the AI separates the subject from the background and models rounded forms, so faces, animals and ornaments come out with believable depth. 1 credit per image.
Upload PNG, JPG, WEBP, HEIC or AVIF up to 20 MB. Export PNG, BMP or STL. 1 credit per run.
Use the height map for 3D engraving on fibre and CO₂ lasers that vary power by gray level.
Create embossed card designs and layered paper reliefs from the depth levels.
3D print lithophanes and wall plaques from a photo.
Sell carved wooden signs, coasters and plaques made from customer photos.
Tip 1: Pictures with soft side light give the most convincing depth.
Tip 2: Remove the background first for a cleaner relief that stands out from the base.
Tip 3: Raise smoothing for wood carving and lower it for metal or resin printing.
Tip 4: Check whether your software reads white or black as high and use Invert if needed.
A grayscale image where brightness stands for height. CNC and 3D software read it to carve or build a surface.
CNC routers (Carveco, Vectric Aspire, Easel), 3D printers through the STL, and lasers with 3D or grayscale engraving modes such as LightBurn and xTool.
The free tool converts brightness to height directly in your browser. The AI relief understands shapes, so a dark eye is not carved as a hole.
Yes. Line art and logos become raised or engraved reliefs with soft bevels.
