How it works
- Scan your drawing, or photograph it from straight above in even light.
- Drop the image onto the box. The clean-up strength starts low so faint lines survive.
- Press Make line art transparent. Raise the strength if paper texture remains, or lower it if lines break up.
- Download the PNG and import it into your painting app as a new layer.
Frequently asked questions
- How do I use it in Procreate, Clip Studio Paint or ibisPaint?
- Import the PNG as an image and use it as the line art layer. The background is already transparent, so you can add a layer underneath and start colouring without any line extraction in the app.
- Can I make all lines black?
- Yes. Set Colour of what is kept to Black and grey pencil or blue pen becomes black. Pressure differences stay as transparency, so the lines keep their weight.
- What happens to coloured areas?
- Coloured areas are kept, minus the white of the paper mixed into them, so pale watercolour washes come out lighter. For the cleanest result, make the line art transparent before colouring.
- Is my drawing uploaded?
- No. It is processed in your browser and never leaves your device. The free plan handles 3 images per run, 20 MB each and 10 runs per day.
