Normal Map Generator from Image: Free, No Upload

Normal Map Generator

Drop a PNG, JPEG or WebP image

Normal map generator

Free normal map generator—no upload. Choose File → Open image… or drop a PNG, JPEG or WebP image to turn it into a tangent-space normal map. Use Open example to try it first. Files are processed on your device; an image can be up to 64 MiB and 16 million pixels. The generator shares the same algorithm and parameters as the editor's Generate Normal Map.

Adjust generation settings

Under Normal map, pick a preset: Architecture, Character, Object or Terrain. Each preset ships a tuned parameter set.
Use Shape strength for silhouette depth, Normal strength for surface slope detail, and Smoothing and Facets for how soft the surface reads.
Raise Painted light and set Light angle to fold hand-painted shading into the map; enable Merge outlines to keep inked outlines as shapes; enable Invert Y for DirectX-style green output.

The preview regenerates as soon as a parameter changes. Picking a preset resets only the strength-type sliders; it keeps Invert Y and the painted light settings.

Export the normal map

Click Export… and choose Export normal map (.png) to download the result.
Click Edit more to open the normal map in the Xprite editor as a new project, where you can layer it with the original artwork or repaint regions.

The exported PNG keeps the source dimensions and uses the source file name with a -normal suffix. The default output is OpenGL-style; enable Invert Y before exporting for DirectX-style maps.

Free, no account, no upload. If the source is a photo or illustration, convert it with the Image to Pixel Art tool first—the generated map then follows hand-placed shading instead of photographic gradients.

Free normal map generator—turn a sprite or texture into a tangent-space normal map, no upload, then Edit more in Xprite. Starting from a photo or drawing? First make pixel art with the free image to pixel art converter, then generate its normal map here. Need animation frames as one image? Use the free GIF to sprite sheet converter —no upload—for a PNG sheet and JSON frame data.

Is the normal map generator free?

Yes. Free, no account, and no watermark. Open the tool and generate in your browser.

Do I need to upload my image?

No. Processing stays on your device. Drop or open a PNG, JPEG, or WebP—the file is never uploaded to a server.

What kind of normal map does it make?

A tangent-space normal map in the common purple encoding: X to red, Y to green, Z to blue. Enable Invert Y for DirectX-style output; leave it off for OpenGL-style output.

What does Edit more do?

Edit more opens the generated normal map in the Xprite editor as a new project so you can repaint regions, combine it with the original artwork, or save .aseprite.
