What graphsmith is
graphsmith is a small set of free tools for making charts and graphics. You type or paste your data, adjust the look, and download the result as an image or a vector file. There is no account to create and nothing to install. graphsmith is operated by Westernmost LLC, 32 N Gould St, Sheridan, WY 82801, USA.

How the tools work
Every tool runs entirely in your web browser. When you edit a chart, the drawing is done by code on your own device. When you convert an image, it is traced on your device too. We do not receive your data, your text or your images, and we do not store them.
Your most recent work in each tool is kept in your browser's local storage so it is still there when you come back. You can clear it at any time with the Start over button or by clearing your browser's site data.
Who it is for
Students and teachers who need a clean chart for an assignment, people who put together reports and slides, marketers who need a graphic in the right size, and makers who need a vector file for a cutting machine or a laser. If you have an idea for a tool that would help you, we would like to hear it on the contact page.
