- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Exporting handwritten notes from OneNote to a PDF file.
- Observed behavior
- Decimal points drawn with a stylus are visible in OneNote but disappear in the exported PDF file.
Make sure your current OneNote notebooks are fully synced to OneDrive before you begin troubleshooting the PDF export settings.
Test the Exported PDF in Alternative Viewers
Determine if the missing decimal points are caused by a rendering problem within a specific PDF viewer rather than a OneNote export defect.
Different PDF viewers utilize different rendering engines. Sometimes the ink data is successfully exported by OneNote, but the PDF reader fails to display tiny stylus strokes, misinterpreting them as background artifacts.
Locate your exported PDF file in Windows File Explorer, right-click the file, select 'Open with', and choose 'Microsoft Edge'.
Repeat the right-click process and select 'Adobe Acrobat' or 'Google Chrome' to view the PDF. Check closely to see if the decimal points appear in these alternative programs.
If the dots appear in one viewer but not another, the issue lies with the specific viewer's rendering capabilities rather than a failure in OneNote's export function.

Update OneNote and Adjust Handwriting Style
Ensure OneNote has the latest ink-recognition patches and alter how decimal points are drawn to avoid them being filtered out as ink noise.
Reinstall OneNote and Report the Defect
If the issue persists across all PDF viewers, reinstall the application to fix corrupted files or report the bug directly to Microsoft.

Frequently Asked Questions
Why does OneNote remove my handwritten decimal points when exporting to PDF?
OneNote's handwriting recognition engine may sometimes misinterpret small dots or decimal points drawn with a stylus as 'ink noise' or accidental marks. When exporting to PDF, the engine attempts to clean up the document, which can inadvertently remove these legitimate marks.
How can I prevent stylus marks from disappearing in OneNote PDF exports?
Try drawing the decimal points slightly larger or pressing harder with the stylus to ensure they are registered as intentional strokes. Alternatively, you can mix typed text for crucial punctuation like decimal points to guarantee they are rendered correctly.
Does the choice of PDF viewer affect whether my handwritten notes appear?
Yes. Different PDF viewers like Microsoft Edge, Google Chrome, or Adobe Acrobat use distinct rendering engines. A tiny stylus mark that appears missing in one application might render perfectly in another, so testing multiple viewers is always recommended.
Is there a way to report ink recognition bugs in OneNote without exposing personal data?
Yes, you can use the built-in Feedback tool in OneNote. When attaching screenshots to support tickets or public forums, always use an image editor to blur, black out, or crop sensitive organizational information, email addresses, and private data.
