Tiny Sprite Prep — Offline Sprite Prep & Preflight

Cut sprites. Ship clean.

Tiny Sprite Prep is a compact, offline image workbench for independent game developers and pixel artists. Download it once, open one HTML file, and get repetitive sprite-preparation jobs out of the way.

Four focused tools

• Sprite Slicer: Set frame size, offset, and spacing; inspect the slice grid; preview animation; export every frame in one ZIP.
• Palette Lab: Extract 2–24 representative colors, copy HEX values, quantize art with optional ordered dithering, and export PNG or GIMP .gpl palettes.
• Pixel Scaler: Enlarge pixel art from 2× to 12× with hard, clean edges and optional transparency.
• Asset Preflight: Check dimensions, alpha, approximate colors, format, file weight, and current slice geometry before importing an asset into your engine.

Private by design

Your unreleased characters, environments, and client artwork stay on your computer. The toolkit makes no network requests and includes no analytics, accounts, ads, subscriptions, or third-party libraries.

Requirements

• A modern desktop browser
• PNG, JPG, or WEBP source images
