Pixel Snapper for RPG Map Assets

Clean up uneven pixel art for props, icons, tiles, and textures before using them in an RPG map workflow.

Quick answer: Pixel Snapper takes a messy sprite or small map asset, detects its intended pixel grid, quantizes the palette, and outputs a cleaner PNG. It is useful for RPG props, icons, tiles, and textures—not full battle-map exports.

Snap pixel art to a clean grid

Upload a small PNG or JPEG, choose palette size, optionally force pixel size, then download a snapped PNG.

Asset packs Battle map maker

Keep uploads under 8 MB and 2048×2048. For best results, use small sprites, props, tile details, icons, or texture swatches.

When to use it

Asset cleanup before map building

This tool is aimed at small pixel-art assets. For full maps, use the editor's normal map and PNG export workflow.

Props and stamps

Clean up uneven barrels, doors, signs, crystals, furniture, loot icons, or encounter props before you add them to a map.

Tile details

Normalize small tile fragments or texture swatches when their pixel sizes drift across the image.

Palette discipline

Use a smaller color count when an asset needs a stricter pixel-art palette rather than painterly gradients.

FAQ

Pixel Snapper FAQ

What does Pixel Snapper do?

Pixel Snapper turns a messy sprite or small asset image into a regular grid of quantized pixels. It is useful when AI-generated or procedural pixel art has uneven pixel sizes.

Can I use Pixel Snapper for RPG map assets?

Yes. Use it for small props, icons, tiles, and texture details before bringing assets into an RPG map or VTT workflow. It is not meant for full-size battle map exports.

What image formats are supported?

The current tool accepts PNG and JPEG uploads, processes them on the server, and returns a snapped PNG.

What do color count and pixel size mean?

Color count controls palette quantization. Pixel size can be auto-detected, or you can override it when you already know the source image's intended pixel grid.

Is this Sprite Fusion's Pixel Snapper?
