ドット絵・スプライトシートメーカー：インディー開発者向けピクセルアート＆アニメーション

GIF64 — Pixel Art & Spritesheet Maker GIF64 is a lightning-fast, simple, and powerful tool for creating pixel art, 2D spritesheets, and animated GIFs. Design frame-by-frame animations on fixed-size canvases (8×8 to 64×64), perfect for retro games, game jams, indie dev, and classic pixel workflows — right on your phone or tablet. Choose a canvas size, draw with pixel-perfect tools, animate using onion skinning, rearrange frames with drag-and-drop, and export clean GIFs or PNG spritesheets. Works fully offline — no sign-in, no tracking, no analytics. Built for Pixel Artists & Game Developers GIF64 is designed around the core mechanics of pixel animation, not bloated features. It stays fast, precise, and predictable — ideal for low-resolution art, retro aesthetics, and production-ready assets. Whether you’re sketching an idea, animating a character, or exporting sprites for a game engine, GIF64 keeps the workflow tight and efficient.
