Image splitter
Drop a wide image and split it into N evenly-sized slides for your carousel. Runs entirely in your browser — nothing is uploaded anywhere.
Best results when the source image is already sized to your target aspect (1080 × N×1350 for portrait carousels, for example). The slicer divides by pixel count, so a 4500×1080 image at 3 slices gives you three 1500×1080 frames — keep the divisor clean.
