Turn Any Photo Into Line Art

Line art is an image reduced to its outlines — the boundaries between shapes — with shading, texture and colour removed. It is the basis of colouring pages, tattoo stencils, embroidery patterns and paint by numbers canvases, because an outline tells you where one area ends and the next begins.

Upload the photo to the generator above. It groups the image into regions of similar colour, traces the boundary of each region, then draws those boundaries as vector paths. Switch off fill and numbers in the result view and you are left with outlines only, which you can download as a PNG or print.

Photos with a clear single subject, good lighting and a simple background. Strong contrast between the subject and what is behind it gives clean, confident outlines. Busy backgrounds break into many small shapes that clutter the drawing, and blurry photos produce vague, wandering lines.

Yes. The colour count controls how many regions the photo is divided into, and therefore how many lines you get. Fewer colours give bold, simple outlines suited to colouring in. More colours give finer detail closer to the original photograph.

Yes — no signup, no watermark, and no limit on how many photos you convert. The conversion runs in your browser rather than on a server, which is why it costs nothing to give away. We sell paint by numbers kits, and some people who use the tool go on to order one.

Yes. The same photo can be made into a custom paint by numbers kit: a pre-printed canvas with numbered regions, pre-mixed acrylic paints matched to your image, and brushes. That is the paid product; the line art tool itself stays free.
