Frequently Asked Questions

This tool supports multiple pixel formats: 16-bit (A1R5G5B5, A4R4G4B4, R5G6B5), 24-bit RGB, 32-bit ARGB (A8R8G8B8), 8-bit indexed color, and PNG with full alpha. Choose based on your game's requirements.

A1R5G5B5 has 1-bit alpha (on/off only) with 5 bits per color channel (32 levels). A4R4G4B4 has 4-bit alpha (16 levels of transparency) with 4 bits per color (16 levels). A4R4G4B4 allows semi-transparency but fewer colors.

Use 32-bit ARGB when your game supports full alpha transparency with 256 levels. This gives smooth anti-aliased edges and gradient transparency. Common in newer games and modern server versions.

Common sizes: 16x16 (Silkroad, Knight Online), 20x20 (ROSE Online), 24x24 (Ragnarok, MU Online), 32x32 (Flyff), 64x64 (TERA). Check your game's documentation for exact requirements.

Check the game's official documentation or community wiki. You can also try different formats - most games will show an error or corrupt image if the format is wrong. Start with 24-bit RGB if unsure.

Select a pixel format that supports alpha (A1R5G5B5, A4R4G4B4, A8R8G8B8, or 8-bit indexed with magenta). Use the Eraser tool to make pixels transparent, or upload a PNG with transparency already applied. The checkerboard pattern in previews shows transparent areas.

Alpha Threshold controls how semi-transparent pixels are handled in formats with limited alpha support. For A1R5G5B5 (1-bit alpha), pixels above the threshold become fully opaque, below become fully transparent. Adjust this when your transparent edges look jagged.

This usually means the wrong pixel format. Try: 1) Check if your game requires a specific BMP format (not PNG), 2) Match the exact dimensions your game expects, 3) For older games, try 8-bit indexed or 24-bit RGB, 4) Some games reject files with alpha channels - use R5G6B5 or RGB.

Yes! This custom tool works for any game. Find your game's emblem specifications (size, format, bit depth) from community wikis or by examining existing emblem files. Input the custom dimensions and select the appropriate pixel format.

Switch to the 'Pixel Editor' tab to draw directly. Use the color palette, drawing tools (pencil, fill, shapes), and Undo/Redo as needed. Start with simple shapes and bold colors - complex details get lost at small sizes.
