Simulate thermal and infrared sensors
Drop in a JPEG, PNG, or WebP to apply a realistic thermal camera effect. The tool estimates “heat” by mapping image brightness through false-color gradients. Lighter areas read as hot, and darker areas read as cold. This works best on high-contrast photos, portraits, and scenes with distinct subjects. Everything renders locally in the browser.
Heat mapping and contrast
The Thermal Palette dictates the style, from the classic FLIR look of Ironbow to the scientific full-spectrum Rainbow or the tactical grayscale of White Hot. Sensitivity controls the contrast between hot and cold zones. Lower sensitivity maps the colors gently across the image, while higher sensitivity creates stark, dramatic separation like a high-gain crt camera effect.
Structure and sensor noise
Because false color can destroy the shapes in a photo, Detail blends the original image outlines back in to keep the subject readable. Sensor noise adds the authentic, slightly gritty texture of an infrared sensor. Lower the detail and increase the noise to recreate the look of a low-cost or long-range scanner.
Tactical HUD overlay
Toggle the HUD overlay to add a decorative targeting interface over the thermal image. This renders a center reticle, corner brackets, a hottest-spot tracking marker, simulated temperature readouts, and a palette scale. For a clean heat map without the interface, turn the overlay off.
