Sprite sheet compression tips

Use these before you upload or share the page.

Keep sprite sheets as PNG for crisp pixel edges; use JPEG only for photo-based sprites like backgrounds.

Resize the sheet to the largest size your game actually displays it at — oversized sheets waste VRAM and build size.

For web builds, WebP often halves sprite sheet size versus PNG with no visible difference on most art.
