How to Translate a Scanned Document
Translating scanned content is more involved. These files usually need text extraction through Optical Character Recognition (OCR) before translation.

A simple method is to use Microsoft OneNote, which includes free OCR functionality.
Steps:
- Open OneNote and click the Insert tab
- Select File Printout and upload your scanned document
- Right-click the inserted image or printout
- Choose Copy Text from This Page of the Printout
- Paste the copied text into a Word document
Step 2: Translate the Extracted Text
Now that the content is in a text-based format, choose one of the following options:
- Use Microsoft Word to translate the document (as shown above)
- Or upload the file to Google Drive, open it with Google Docs, and follow the Google Translate steps for document translation
