Frequently Asked Questions

Why won't the standard eraser tool remove my pen stroke in OneNote?

Sometimes, ink strokes in OneNote can glitch and become embedded in the background or cross over multiple layers, making the standard eraser ineffective. Using the Lasso Select tool usually bypasses this issue.

Will exporting my OneNote page to PDF keep my notes editable?

No, exporting a page as a PDF and re-inserting it as a File Printout will convert your handwritten notes and text into a static image. You will no longer be able to edit the original ink strokes.

How do I prevent pen strokes from getting stuck in OneNote?

Keeping your OneNote application updated to the latest version and avoiding excessively large notebooks can help minimize syncing and rendering glitches that cause stuck pen strokes.
