Piskel
piskelapp.com
A browser-based pixel art editor with frame-by-frame animation, layer support, and sprite sheet export — no install required.
Piskel offers a focused drawing grid built around pixel art constraints, with support for multi-frame animation, layer management, real-time preview playback, and export to PNG sprite sheets or GIF. Everything runs client-side without accounts or downloads.
Why it is useful
Professional tools like Photoshop are poorly suited for pixel-accurate frame animation work. Piskel is purpose-built for it — the constraint-first grid, frame timeline, and one-click sprite export make it the fastest path from idea to game-ready asset for indie developers and hobbyists alike.
