Generate tiny inline sparklines from a list of numbers, with min and max markers and area fill, ready to paste as SVG or PNG.. Sparkline Generator is a free online tool from the ToolsRift Charts & Data Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Paste your numbers separated by commas, spaces or new lines, choose the fill, marker and colour options, then download the sparkline as an SVG or a PNG.
A sparkline is a small word-sized chart with no axes, designed to sit inline in a table, a dashboard cell or a sentence. It shows the shape of a trend rather than exact values, which makes it perfect for showing dozens of series compactly.
Yes. Download the SVG and drop the file into a document, or open it in a text editor and paste the markup straight into your HTML — it is plain inline SVG with no external dependencies, scripts or fonts required.
When markers are enabled the tool highlights the lowest point, the highest point and the most recent value. Those three markers give a reader the range and the current position instantly without needing any axis labels.
