How to Make a Sprite Sheet: Prepare Frames
The first step in how to make a sprite sheet is preparing the images, not choosing columns. Export one PNG, JPG, or WebP for each chronological pose. Use descriptive numbered filenames such as walk-01.png through walk-08.png. Natural filename order makes the initial import predictable, while the frame list still lets you correct or reverse the sequence.
Keep the camera and character scale consistent. A foot should not grow larger because the pose changed. Preserve enough canvas room for the widest weapon swing, highest jump, longest hair movement, or largest effect. If every frame is tightly cropped to different visible bounds, a tool can pack them but the animation may wobble because the coordinate origins no longer match.
Use transparency for characters and effects that must appear over different backgrounds. Inspect pale outlines over both dark and light surfaces. Remove accidental matte colors before packing. For pixel art, export at native integer dimensions and avoid resampling. For illustrated art, keep the same resolution and color profile across the set.
Decide whether repeated images are intentional timing holds. A fixed-FPS player can make one pose last twice as long by including it twice. Remove accidental duplicates but keep deliberate ones. This is also the moment to decide whether one file contains a single action; walk, attack, and hurt usually belong in separate sheets or documented ranges.
