Depth Anything 3 · 16-bit · STL
Free AI Depth Map Generator from Any Photo
A free online AI depth map generator. Upload a photo, press Generate, and a server model returns a 16-bit depth map. Depth, invert, and crop then stay in the browser. Download the PNG or a closed STL for LightBurn 3D Sliced, 3D printing, or CNC.

What this does
A depth map for every maker surface.
Depth-Map.com turns one photograph into a 16-bit grayscale depth map and a closed STL. Generate uploads the photo once. A metric Depth Anything 3 model estimates depth on a server. Thickness, invert, gamma, and crop then stay in the browser.
A depth map is a grayscale image where brightness encodes 3D height — white for near, black for far. Makers consume them in four physical forms: fiber-laser engraving (LightBurn 3D Sliced), CNC bas-relief machining (Carveco, ArtCAM, VCarve), 3D printing (Bambu Studio, PrusaSlicer for lithophanes and reliefs), and 3D rendering (Blender Displacement Modifier, ZBrush alpha brush). We tune the workbench for all four — a single depth map export covers the whole workflow.
The 16-bit depth map is the manufacturing file. An 8-bit PNG stores 256 height levels. This PNG is 16-bit, on a 10 mm scale, so a 3 mm relief peaks at 19661 rather than 65535.
Who uses it
Built for six maker surfaces.
One depth map export covers every downstream process a maker needs. Pick your surface — the parameters and presets follow.

Fiber laser engraving
Starting power and frequency for brass, silver, stainless, aluminum, and copper. Copy a row into LightBurn. There is no project file.
Laser parameters →
Challenge coin design
0.8 mm depth on a 1.2 mm base. The long side starts at 40 mm. Rim and lettering stay in the laser file.
Coin workflow →
3D-printed lithophanes
Inverted depth, 2.8 mm of relief on a 0.6 mm floor. The mesh is a flat closed STL, not a curved shade.
Lithophane maker →
CNC bas-relief machining
A closed STL from the portrait sample: 5 mm relief on a 2 mm base. The long side starts at 40 mm.
Image to STL →
Blender + ZBrush
Import the 16-bit PNG on a Displacement modifier or as a ZBrush alpha. EXR is not an export.
Displacement workflow →
Jewelry prototyping
The same 16-bit PNG and STL. Studio is listed at $49 a month. This version does not add a separate commercial file.
Commercial use →How it works
Four steps from photo to fabrication.
- 01
Upload
PNG, JPEG, or WebP up to 8 MB. The lion sample is already loaded.
- 02
AI depth inference
Generate sends the photo once. There is one model size. The reply is a 16-bit field.
- 03
Tune
Set depth and base in millimetres. Invert, gamma, flatten, and crop do not call the model again.
- 04
Export
16-bit PNG for LightBurn or a CNC. Closed STL for a printer. The long side starts at 40 mm and can be changed without another Generate.

Frequently asked
Honest answers about what depth-map.com does, how it works, and when to use something else.
From the blog
How the 16-bit file is scaled, and how the STL long side is set.
How to read the 16-bit PNG
The raw model file reaches 65535. A 3 mm manufacturing file peaks at 19661, because full scale on this site is a 10 mm span.
Size a relief STL
The long side starts at 40 mm. The slider runs from 10 to 200 mm and does not call the model again. The mesh is closed.
The lion sample is already loaded.
Replace the photo and press Generate. That upload happens once. The sliders after it stay in the browser.
