To convert handwritten notes to a PDF, you can start by scanning the sheet using a scanner and saving the image in PDF format. If you don't have a scanner, you can use a scanning app on your smartphone to capture the image of your notes and save it as a PDF.
Once you have the PDF, you can use a tool like Adobe Acrobat to convert the scanned image to text using Optical Character Recognition (OCR) technology. To do this, open the PDF in Adobe Acrobat and click on the Edit PDF tool in the right pane. Acrobat will automatically apply OCR to your document and convert it to an editable copy of your PDF. You can then click on the text element you wish to edit and start typing. The new text will match the look of the original fonts in your scanned image.
Alternatively, you can use a dedicated app to scan and convert handwriting to text with OCR to PDF. Some of the best apps for this purpose include Microsoft Office Lens, Google Lens, and Adobe Scan. These apps allow you to capture an image of your handwritten notes, and then use OCR to recognize and convert the handwriting to text. The converted text can then be saved as a searchable and editable PDF.
