Coloring Page Maker by amit7000

Coloring Page Maker turns any picture or photo into a crisp, printable coloring page — black outlines on white paper, formatted specifically for A4 or US Letter printing.

Everything runs 100% client-side inside your browser: there is no upload endpoint, no database, no cloud processing, and no server-side image manipulation anywhere in the product. Your family photos and personal artwork never leave your computer.
Key Features:

Instant Local Processing: High-performance WebWorker pipeline runs Sobel edge detection and Extended Difference of Gaussians (XDoG) directly in your browser.
Print-Ready PDF & PNG Export: Download vector-aligned PDFs formatted for A4 or US Letter, with physical line thickness calibrated in millimeters so home printers never drop thin lines.
Fine-Tuned Controls: Adjust detail level (Low, Medium, High), line thickness, despeckle filter, and algorithm style to suit pets, portraits, architecture, or landscapes.
Chrome Right-Click Extension: Right-click any image on the web and select "Create coloring page" to instantly load it into the editor.
100% Free & Unrestricted: No sign-up, no subscriptions, no accounts, no watermarks, and no ads.
