This tool applies a cyanotype effect to your photos directly in the browser. It acts as a cyanotype simulator, recreating the classic blue photographic print style with rich shadows, luminous midtones, and pale paper highlights.
The cyanotype filter online works entirely client-side. Your images are never uploaded to a server. You can export the final blueprint-style image instantly.
Cyanotype presets
Choose a preset to set the overall print mood. The Classic Prussian option balances rich blue shadows with a gently warm paper base. Vibrant Wash provides a brighter, more luminous feel. Deep Sea creates a denser, moodier print, while Antique Botanical warms the paper for an archival, hand-processed look.
These presets shift the tonal character and paper base to give you a quick starting point. Use the Surprise me ✨ button in the cyanotype generator to create random, process-inspired variations.
Tone and exposure
Adjust the Exposure Base to shift the print lighter or darker before the cyanotype converter applies the blue mapping. Chemical Contrast controls the separation of tones—lower values create soft roll-offs, while higher values produce punchy, blueprint-like results.
The Dye Density slider determines how concentrated the dark blues feel. Increase it for dramatic depth, or lower it for a faded, delicate print. The Paper Aging control adds warmth to the lighter regions, shifting the cyanotype filter away from a clinical blue toward a sun-softened, antique finish.
Material character
A convincing print must recreate the tactile surface of coated paper. The Water Stains & Fibers slider adds large-scale variations like wash irregularities, edge bleaching, and paper absorption.
For finer detail, use Pulp Clumping to introduce surface grit, speckling, and natural paper grain. These controls break up digital perfection, making the final image feel like an authentic, handcrafted botanical print.
