Photo to Contour Line Art
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Transform your photos into stunning contour art. Export as SVG, PDF, or PNG. Try 5 photos free, then unlock unlimited access.
IsoDrift transforms any photo into beautiful contour line art — the kind of flowing, topographic artwork you'd hang on a wall.
Pick a photo, and IsoDrift instantly traces the contours of light and shadow across your image, creating intricate line drawings that reveal the hidden structure of your pictures. Portraits become sculptural. Landscapes become topographic maps. Even everyday snapshots turn into something worth framing.
HOW IT WORKS
Drop in any photo and IsoDrift transforms it into flowing contour line art in seconds — right on your device, no internet required.
Tap anywhere on the canvas to set your origin point and watch the artwork shift and reshape around it. Move the origin, change the art. Every photo holds hundreds of unique compositions waiting to be discovered.
FULL CREATIVE CONTROL
- Lines: Control how many contour lines are drawn, from sparse and minimal to dense and detailed.
- Thickness: Adjust stroke weight from hairline-thin to bold and graphic.
- Image Fade: Blend the original photo behind the contours for reference, or keep it pure line art.
- Themes: Choose from five visual themes — Light, Dark, Blueprint, Sepia, and Neon.
- Origin Point: Tap to place the contour origin anywhere on the canvas. Each position creates a unique result.
EXPORT YOUR ART
- SVG: Scalable vector files, perfect for printing at any size or editing in Illustrator, Figma, or Affinity Designer.
- PDF: Print-ready vector output for high-quality physical prints.
- PNG: Save directly to your camera roll for sharing on social media.
- Export All: Save every format at once with a single tap.
Every export prompts you to name your file, so your artwork stays organized.
