Grid Maker
Upload a reference photo and lay a grid over it to transfer proportions accurately onto your canvas or paper. Pick a page size to print at true scale, then zoom and drag the photo to fit.
Palette Extractor
Upload an image to pull out its dominant colours as a ready-to-use swatch set. Click any swatch to copy its hex code.
Line Art
Upload a photo to convert it into clean line art for tracing or colouring.
Black & White
Upload a photo and convert it to grayscale. Pick a look, then fine-tune the contrast.
Value Mapper
Upload a reference photo and flatten it into a handful of shading values — the classic way to block in tone before you paint or draw.
Symmetry Checker
Upload a portrait and mirror it to catch proportion errors your eye glosses over when looking at the original.
Posterize
Upload a photo and flatten it to a handful of colour bands — a reference for cel-shading, paint-by-number, or simplified colour blocking.
Perspective Grid
Build a 1, 2 or 3-point perspective guide. Upload a photo to trace over, or start from a blank sheet.
Halftone
Upload a photo and convert it into a dot-pattern halftone print — set how many dots run across the image to control detail.
Format Converter
Convert HEIC (iPhone photos), WEBP and other image formats into JPG or PNG for easy sharing and printing.
