How do I turn a note into a pdf to email?

Not an available option.

For clarity, in pictures…

The ellipsis button in Notes:

Select Print from the action menu:

Long touch the Print button:

Finally, Save to Files:

A really easy method of creating a PDF file from Apple Notes is simply to tap the ellipsis (three dots) button at top right of the screen - then select Print. The print dialogue will open - and from here you have two options:

1) Touch-and-hold (i.e., a long touch) the Print button at top right; from the action menu, select Save to Files.

2) Use a two-finger “zoom-out” gesture on the thumbnail image of the note. Your note will open in a new page; tap the Share button - and select Save to Files.

In both cases, this will save a PDF version of your note to wherever you choose to save it.

The ellipses button didn’t have the Print option; however, if you swipe the note to the left ◁ you will find a share button.

Everything after was as you had described.

Thanks to you, I learned something I never knew. 👋🏼😎

Well, I have no less than four different iPad’s that indicate otherwise.

The screenshots came from an iPad Pro 12.9 M1 with iPadOS 15.7 installed.

That’s why your options are different. 🫤
