Manually correcting these issues is time-consuming, so automated cleanup tools can quickly improve text quality.

For general documents, selecting 'Normalize line breaks', 'Normalize whitespace', and 'Trim whitespace per line' resolves most issues. For English documents, additionally enable 'Remove hyphenation' and 'Fix OCR errors'. If scanning books with page numbers, 'Remove page numbers' is also useful.

Complete Guide to OCR Text Cleanup

Importance of OCR Post-Processing

OCR technology automatically extracts text from images and scanned documents, but results often contain various errors due to document layout, image quality, and font variations. Unnecessary line breaks, double spaces, broken special characters, and hyphenated words are common issues that are inefficient to correct manually.

Benefits of Automated OCR Cleanup

Automated OCR cleanup tools save significant time. Manual correction of one page takes 10-20 minutes, but automated tools process dozens of pages in seconds. Consistent rule application also maintains uniform correction quality across all text.

Notice

This tool cleans text based on common OCR error patterns. Always review the automated cleanup results before use, especially for legal or contractual documents where accuracy is critical. All processing is done in the browser with no server data transmission.
