Hey there, I totally get where you're coming from—tiny icons can be such a hassle when your vision isn't as sharp as it once was, especially when you need to quickly spot linked documents in your OneNote pages.

Let me start by being upfront: OneNote doesn’t have a built-in feature to resize that default link icon (the one with the PDF thumbnail snippet and partial document title). It’s a bit of an oversight, but there are a few practical workarounds you can try to make these links easier to see and interact with:

• Create a custom linked image: Instead of using the default inserted link icon, grab a large, clear icon (like a big PDF or document icon you can make or copy) and add it to your page. Right-click the image, select Link, and attach your document’s file path or URL. You can resize this image to any size that works for your vision.
• Zoom in on the entire page: Use the zoom slider in the top-right corner of the OneNote app, or use the keyboard shortcuts Ctrl + + to zoom in and Ctrl + - to zoom out. This will make all elements on the page—including those tiny link icons—appear larger. It affects the whole page, but it’s a quick, no-fuss way to boost visibility.
• Add a large, linked text label: Type out a clear, bold label (like "Monthly Report PDF") in a large font size next to the default link icon. Right-click the text, select Link, and attach your document. This gives you a bigger, easier-to-read target to click on, even if the icon itself stays small.

I hope these tricks help you out—they’re not a perfect fix, but they’re the most reliable options we have right now until Microsoft adds native resizing support for these link icons!
