9 useful places to start.
Atlases use fixed cells in input order. Normal maps interpret brightness as height and state their green-channel convention.
Sprite sheet and frame manifest
Pack several images into a fixed-cell PNG atlas with coordinate JSON.
Image grid tile splitter
Split an image into numbered PNG tiles and download a ZIP.
Image to pixel-art SVG
Create a compact vector mosaic from a sampled and quantised picture.
Height image to normal map
Build a tangent-style normal texture from a greyscale height interpretation.
Texture repeat and seam preview
See a 3-by-3 repeat to inspect visible texture edges.
Extract image alpha mask
Export the transparency channel as an opaque greyscale PNG.
Trim transparent image borders
Crop to the visible alpha bounds and download the trimmed image.
Pixelate image
Build a coarse sampled grid and enlarge it into visible pixel blocks.
Image colour palette extractor
Extract a sampled palette, inspect colour contrast and download reusable swatches.
