How to use Generate Random Lines
- 1. Set the canvas size. Enter Width and Height to size the drawing area in pixels. Larger canvases give the lines more room to spread out and overlap.
- 2. Set how many lines to draw. Enter How many lines to control the density of the tangle. A small number reads as sparse scribbles, a large number fills the canvas with crossing strokes.
- 3. Review the rendered lines. The tool draws random line segments with random colors and stroke widths as an SVG image. Regenerate to see a new tangle, or download the result.
When to use Generate Random Lines
Generate Random Lines scatters random colored line segments across a canvas as SVG art, useful for quick abstract backgrounds or testing how a renderer handles many overlapping strokes at once.
- Abstract background for a portfolio site. You want a scribble-style background texture for a personal site's hero section. Generating a tangle of random lines at your page's dimensions gives you a quick placeholder.
- Stress testing an SVG rendering library. You are checking how your SVG renderer performs with many overlapping stroke elements, so you generate a large number of lines to see how it holds up.
- Sketching a scribble art style. A design brief calls for a hand-drawn scribble aesthetic. Generating random lines at varying stroke widths gives you a starting texture to riff on.
- Demonstrating SVG stroke properties. You are teaching how stroke color and width attributes work in SVG and want a live example with many differently styled line segments to point to.

About the Generate Random Lines tool
Generate Random Lines does its work locally, right in the browser. Draw random line segments with random colors and stroke widths. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Random Tools collection on EditSafely, a set of 120 small, focused Random utilities that share the same instant, private workspace.
You can shape the output with 3 settings, including Width, Height and How many lines, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
