Sprite Sheet to GIF
Slice an existing PNG sheet into frames, set the timing and loop, then export an animated GIF.
Frame preview
Choose PNG frames, a PNG sprite sheet or a GIF to preview here.
How to use this tool
Choose a sheet
Select a PNG and optionally its companion JSON. Set a grid or exact frame dimensions when metadata is not available.
Preview the sequence
Preview frames after geometry changes. Choose a range and set source timing, FPS or per-frame durations.
Export and check
Convert to GIF and inspect colors, transparency and playback timing. GIF cannot preserve every PNG color or partial alpha value.
Questions
Not always. GIF uses indexed colors and a single transparent palette entry. Semi-transparent edges must be thresholded, and colors may be quantized.
GIF stores delays in hundredths of a second. Some viewers clamp very short delays, so compare the exported file in its destination player.
