Graph Almost Anything from High School Math

GraphFree is an incredibly flexible online graphing tool, boasting capabilities not found even in the most popular graphing calculators. Whether you’re a teacher who wants to make better graphs for tests, or a student looking for homework help, GraphFree is made for you.

Best of all, it’s completely free. You don’t even have to register. Just click the button and start graphing.

Graph circles, ellipses, and hyperbolas with the convenient implicit plot type.

Plot piecewise functions quickly and easily, including open and closed endpoint symbols.

Easily add horizontal, vertical, or slant asymptotes to any graph.

Graph polar or parametric curves, ordered pairs, or intervals on a number line.

Illustrate inequalities or the area between curves with flexible shading options.

Plot slope fields for your AP Calculus tests. Where else can you do that?

Graph up to six different curves on one set of axes, complete with legend if you wish.

Drag your custom notes into position with the mouse.

Right-click the graph to save it to your hard drive as a PNG file.

You can usually also copy the graph to the clipboard and paste it into your word processor, presentation program, etc., but sometimes you need a special kind of paste command. See the FAQ or User’s Guide for details.

(Values are in pixels and do not include caption or legend.)

Note: Shading instructions will be ignored for any plot not of type "Function."


Enter the text of one or more notes to be placed onto your graph. You will be able to drag the notes into position after you create the plot.
