Thyroid black outline icon
Outline of a butterfly-shaped thyroid gland wrapped around a segmented trachea
About the Thyroid black outline icon
The drawing shows the two lobes of the thyroid gland spread like butterfly wings on either side of a windpipe, with the segmented cartilage rings of the trachea running below and the larynx notch shaping the top. It communicates endocrine function, hormone balance and metabolism. Fits hospital and clinic sites, endocrinology patient leaflets, lab result screens, anatomy teaching slides and health tracking apps.
Built from one symmetrical two-lobe silhouette with small curved marks suggesting tissue texture, balanced against a ladder of rectangular tracheal rings that anchors the composition vertically. It sits well beside other organ icons such as lungs, kidney and pancreas. Keep it at 32 px or larger so the ring segments stay readable.
This is the black outline version of the thyroid icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
