About this site

Who makes it

The site is written, built, and maintained by Amit Choukroun, a software developer. There is no company behind it and no team — the name on the copyright line at the bottom of every page is the same person who answers the email on the contact page. That is worth stating plainly, because it sets expectations: replies come from a human rather than a helpdesk, and there is no account system, no sales process, and nobody to upsell you.

Why it works the way it does

Nearly every coloring-page converter asks you to upload your photograph to a server. For a holiday snap that is merely impolite. For a picture of somebody's child, or a page of a pupil's work, it is the whole problem. The technique involved — edge detection — has run comfortably on ordinary hardware since the 1980s, so there was never a good reason for the picture to leave the machine it was opened on.

So it does not. The conversion runs inside a background worker in your own browser, and the site operates no server that could receive an image even if it wanted one. How it works walks through the pipeline step by step, and the privacy policy sets out the one exception worth knowing about: the third-party advertising and analytics code described below, which never touches your pictures but does see that you visited.

What is here

• The converter — choose a photo, adjust the detail and thickness, and download a print-ready PDF or PNG.
• 160 printable coloring pages across 16 subjects, made for this site, free to print at home or in a classroom.
• A colouring canvas on every one of those sheets: a paint bucket, brush, undo, and a palette, saved in your browser so a half-finished page is still there tomorrow.
• A Chrome extension that adds “Create coloring page” to the right-click menu on any image.
• Written guides — the printing guide, for parents, for teachers, and the articles.

How it is paid for

Advertising, and nothing else. The site carries Google AdSense, and that revenue covers the domain, the hosting, and the time spent making new sheets. There is no paid tier, no subscription, no watermark to remove, and no feature held back for a version that costs money. Everything described above is free and stays free.

The trade you are making is the ordinary one: you see advertising, and Google sets cookies to choose which advertising. What that involves, and how to turn personalised ads off, is set out in the privacy policy rather than summarised loosely here.

What it is not

The converter is not an AI image generator. Nothing is invented, imagined, or borrowed from a training set — the outlines you get are the boundaries that were already present in the picture you supplied, found by an algorithm that predates the term “machine learning”. It does not have accounts, so there is nothing to sign up for and no password to lose. And it does not store your images, because it never receives them.

The 160 sheets in the gallery are a different matter, and it is worth being exact about it: each one starts as an image-model generation commissioned for this site, then gets checked by eye, redrawn when the lines come out broken or the outline leaks, and processed into the print files you download. They are made here rather than collected from elsewhere — this is not a marketplace and nothing in the gallery was scraped from another site — but they are not drawn by hand, and it would be dishonest to imply otherwise.

If something on the site is wrong, broken, or claims more than it delivers, that is worth an email — the contact page says where to send it.
