• Image enhancement and detail improvement
• Mask-guided watermark / region inpainting
• Transparent PNG export

Processing Modes

Object

Convert ordinary images or AI-generated images into pixel art objects with transparent backgrounds.

The tool automatically detects and removes the background, processes the main subject, and exports it as a PNG asset.

Preset output sizes include:

• 16 × 16
• 32 × 32
• 64 × 64
• 128 × 128

Custom output sizes are also supported when the preset sizes do not meet your needs.

This mode is suitable for creating pixel art objects such as:

• Items
• Props
• Plants
• Decorations
• Characters
• Animals
• Other game objects

Tile

Process terrain and environment images into pixel art tile assets.

This mode is designed for game development workflows involving ground, water, terrain, and other environmental elements.

Default output size:

• 192 × 192

Enhance

Improve image quality and visual details while preserving the original image dimensions.

This feature is useful when an image becomes too blurry or loses important details during previous processing steps.

Watermark / Region Inpainting

Allows users to select a region of an image and attempt to reconstruct the selected area using image inpainting techniques.

The result depends on the surrounding image content.

Large or highly detailed selected regions may produce imperfect results. The software cannot magically recover information that does not exist in the original image. Even software has its limits, inconveniently.

Output

Processed images are exported as PNG files.

In Object mode, transparent backgrounds are preserved when applicable.

Users can select a custom output directory before processing.

System Requirements

• Windows 10 or later
• 64-bit Windows
• The source-code version requires Python to be installed.

Usage

1. Launch PixelNatureGenerator.exe.
2. Select a processing mode.
3. Load an input image.
4. Select the desired output size, or enter a custom size when supported.
5. Adjust the available processing options.
6. Select an output directory.
7. Start processing.
8. Find the generated PNG files in the selected output folder.

Intended Use

Pixel Nature Generator is designed to provide convenient image-processing tools for game development and pixel art workflows.

It does not generate complete game assets from scratch. Instead, it helps convert existing images into formats and styles that are more suitable for use in games.
