Sprite Reel Animation Forge – A Handy MZ/MV Tool

Sprite Animation Forge is a sprite animation studio that runs entirely in your browser. One HTML file, no install, no account, no network. Your art never leaves your machine.

120+ battlers, ready to drop into your RPG Maker project.

Yōkai, cryptids, Norse gods, monster girls, gothic battle maids, cosmic horrors — transparent PNGs built for MZ and MV, and they work in any 2D engine. Plus three tools that do the tedious part for you: animate a sprite from a single frame, turn any PNG into a tileset, and bring your autotiles to life. Twelve releases, from $3.99.

Animate a single sprite

Drop in one still sprite and pick an animation. Sprite Reel builds the frames

for you:

• Platformer — idle, walk, run, jump, crouch, attack, hurt, death
• Top-down — RPG walk, top-down walk and idle, generated for all four facings
• Combat — light attack, heavy attack, block, dash, cast

It reads your sprite’s silhouette to find the head, hips and legs, and ignores

raised weapons so a held sword doesn’t get mistaken for a head. Attacks swing

the upper body as one piece, so a sword crossing the chest stays intact. Slash

arcs, kicked-up dust and speed lines are generated to match.

Tell it which way your artwork faces — right, left, toward the viewer or away —

and the motion adapts. Facing the camera turns a forward lunge into movement

toward you rather than sideways.

Or bring your own frames

• Sprite sheets, auto-sliced with grid detection you can correct
• Loose sprite files
• Animated GIFs, split into frames with their timing preserved

Build sequences by hand on the filmstrip, drop into preset cycles, or add

seeded procedural variation. Onion skinning shows several frames either side,

tinted red for past and blue for future. Undo and redo cover every edit.

Export

• Animated GIF with transparency
• Packed sheet plus data for Phaser, PixiJS, Godot 4, Unity, Starling or CSS
• Trim, padding, extrude, duplicate merging, power-of-two sizing
• Numbered PNG sequence as a zip
• CSS keyframes and JS frame arrays
• RPG Maker MV/MZ character sheets, 48px 3×4, direction mapping pre-filled
• Project files you can reopen later — plain JSON, everything embedded

Known limits

Motion is transform-based, not skeletal. Arms don’t articulate independently,

so an attack reads as a body swing rather than a wrist cut. It can’t invent a

profile view of a character drawn head-on. Segmented mode suits upright,

roughly centred characters; there’s a whole-sprite mode for everything else.

AI disclosure: this tool was developed with AI coding assistance. The tool

itself contains no AI — no models, no network calls, all animation is

deterministic. Demo sprites shown in screenshots are  placeholders and are not included in the download.
