Phantom UI Pixel Editor is a lightweight Unity Editor extension designed for quick sprite, sprite sheet and texture editing directly inside Unity.

Built for pixel-art, retro, horror and 2D projects, the editor lets you open an existing texture from its Inspector or the Assets menu and work on the complete source image. Choose a paint-cell size, edit with familiar painting tools, sample colors, undo changes and save the result directly into your project.

Saved textures are automatically reimported by Unity, making the editor useful for small production changes, placeholder adjustments, sprite sheet cleanup and fast color variations.
