Free Image Depth Map Generator for Laser Engraving & CNC, 3D PRINTING (Offline)

Professional Image-to-Depth Map Software (100% Free & Offline)

DepthGen Pro v1.0.0 — Free Edition is a free, offline image-to-depth-map application designed for laser engraving, CNC carving, relief modeling, and 3D height-map generation.
Unlike online tools or AI-based solutions, it works entirely offline, ensuring full privacy, zero data upload, and maximum control over depth generation.

This is the original v1.0.0 release, and it stays free — no licence key, no watermark, no limits. It is not the current paid release. DepthGen Pro V3 is a different application built on an AI depth engine with a photometric relief pipeline for coins and engraved surfaces, 16-bit and EXR export, batch processing, and depth editing. The full comparison is further down this page.

If your workflow ends in LightBurn, use the 8-bit vs 16-bit depth-map guide to choose the correct export precision and pass count.

This software converts standard 2D images into accurate grayscale depth maps and 3D height-mapped previews using pure mathematical image processing, not artificial intelligence.

3D Engraving & Relief Preview

DepthGen Pro includes a real-time 3D preview engine that simulates how your depth map will look after engraving or carving.

Supported Simulations

  • Laser engraving preview
  • CNC relief carving
  • Height-map surface rendering

3D Controls

  • Adjustable Z-height scale
  • Dynamic lighting and shadows
  • Light angle control
  • Wireframe mode for inspection

This allows you to verify engraving depth before production, saving time and materials.

Export Formats

DepthGen Pro supports professional export formats used in fabrication workflows:

  • PNG grayscale depth map
  • High-contrast laser engraving images
  • STL height-map mesh (for CNC & 3D printing)
  • Engraving-ready grayscale output

All exports are generated locally, with no internet dependency.

100% Offline & No AI

Unlike many tools on the market:

  • No artificial intelligence
  • No machine learning
  • No cloud processing
  • No image uploads
  • No tracking
  • No subscriptions

DepthGen Pro uses classical image processing algorithms and WebGL-based 3D rendering, making it ideal for professionals who require predictable, repeatable results.

Ideal Use Cases

  • Laser engraving on wood, leather, acrylic, slate, and metal
  • CNC relief carving
  • 3D height-map generation
  • Artistic bas-relief design
  • Maker, FabLab, and workshop workflows
  • Privacy-focused offline environments

Technical Overview

  • Runs locally in the browser
  • Works on Windows, macOS, and Linux
  • Responsive design (desktop & tablet)
  • Built with modern web technologies
  • No external APIs required

Free Edition vs. DepthGen Pro V3

Both run fully offline on your own machine and never upload an image. They are built on different engines, so they suit different work:

FeatureFree Edition v1.0.0DepthGen Pro V3

Updates & supportNone — legacy releaseLifetime updates included

If you are engraving photographs on wood or slate and want a free tool that does the job, the Free Edition is genuinely enough. If you engrave coins, medallions, or anything with real surface relief — or you process orders in batches and need 16-bit precision — that is what V3 was built for.

Free to Use

The Free Edition is completely free.
No licence keys.
No hidden limits.
No watermarks.
No trial that expires.

It is the v1.0.0 release and no longer receives updates. Everything described above is what it does today, and it will keep doing it.
