Are these medical illustrations accurate?

Each diagram is drawn to show the structures that carry meaning at teaching size, then reviewed against standard anatomy references. They are intended for education, presentation, and study — not for diagnosis or clinical decision-making.

Can I use these illustrations for free?

Yes. Every illustration in the library can be viewed, downloaded, and used in teaching materials, presentations, and coursework at no cost. Exports are available as SVG and PNG.

Can I use them in my lectures and handouts?

That is the intended use. Every figure is drawn on a 16:9 canvas sized for slide decks, so it drops straight into a lecture presentation. SVG scales without loss for print handouts, and the unlabeled version works for quizzes and worksheets.

How should I describe a structure to get an accurate result?

Name the structure, the view you want, and the level of detail — for example "cross-section of the heart showing the four chambers and valves, labeled". Naming the specific parts you need labeled gives the most usable result.

Which formats can I download?

SVG for a true vector that scales cleanly in slides and print, or PNG at 1x, 2x, or 3x for documents and handouts. A transparent background is available for either format.

Generate Your Own Medical Illustration

Describe a structure, organ, or process in plain language. You get back an editable figure you can relabel, restyle, and export — not a flat picture.

Describe it, edit it, teach it

The mechanism stays separate from the drawing, so you correct the biology without rebuilding the artwork.

01
Describe the mechanism
Write the steps, structures, and direction in plain language, the way you would brief a colleague.
02
Get a structured figure
It comes back on the canvas as labeled entities and relationships you can select, not a picture you cannot touch.
03
Edit, theme, export
Drag to rearrange, relabel, switch palettes, then export SVG or PNG straight into your deck.
