Embed a printable generator
One iframe puts a working PrintNook generator in your own page. No key, no account, no script tag and no tracking. Copy the snippet, leave the credit link at the foot of the widget in place, and you are done.
The snippet
<iframe
src="https://printnook.co/embed/paper"
title="Free printable paper generator by PrintNook"
width="100%"
height="900"
loading="lazy"
style="border:1px solid #dcd6ca;border-radius:8px"
></iframe>Swap /embed/paper for /embed/sudoku to embed the puzzle generator instead. Both widgets are the same tools that run on the paper page and the sudoku page, with the site navigation stripped out.
Who this is for
Teachers putting a graph paper generator on a class page, maths and music departments, tabletop gaming wikis that want hex paper on the page rather than behind a link, and anyone writing about note taking who would rather show the tool than describe it. The widget is more useful than a screenshot for the same reason the site exists: a fixed PDF is somebody else's settings.
The one condition
The credit link stays. It is a plain <a>in the widget's HTML rather than something injected by JavaScript, so it is not going to break your page and it is not going to slow it down. Removing it is the only thing that makes an embed unwelcome here.
Height, and why the widget does not resize itself
Give the frame 900 pixels of height on desktop and it will not scroll. The widget does not post its height to the parent page, because doing that means running a listener on your site, and a tool that promises no tracking should not be asking for a message channel into the host page. A fixed height is the honest trade.
Frequently asked questions
Does it cost anything, or need an account?
No to both. There is no key, no sign up and no usage limit. The widget is the same static page the rest of the site is built from.
Does it track my visitors?
No. The widget runs entirely in the visitor's browser, sends nothing anywhere, and sets no cookies. That is true of the whole site, not just the embed.
What am I required to do in return?
Leave the credit link at the foot of the widget in place. It is a plain link in the HTML, not a script, and it is the only thing asked for.
Will the iframe scroll?
Not if you give it enough height. The paper widget needs about 900 pixels on desktop and more on narrow screens, because the controls stack above the preview.
Can I restyle it?
Not from outside the frame, since an iframe is isolated. If you need it to match your own design closely, say so on the contact page rather than reimplementing it.
Prefer data to a widget?
The paper sizes API gives you the same dimensions as JSON, keyless and CC BY 4.0 licensed, if what you actually need is the numbers rather than the tool.
