How It Works
DocStripper uses a simple but effective line-by-line cleaning algorithm to remove noise from your documents:
Read & Extract
The tool reads your file (TXT, DOCX, or PDF) and extracts all text content. For DOCX files, it extracts text from the document structure. For PDF files, it extracts text while preserving layout.
Line-by-Line Analysis
Each line is analyzed and filtered based on several criteria:
- Empty lines — Removed completely
- Page numbers — Lines containing only digits (e.g., "1", "2", "3")
- Headers/Footers — Common patterns like "Page 1 of 5", "Confidential", "DRAFT"
- Duplicate lines — Consecutive identical lines are collapsed into one
Clean Output
The cleaned text is assembled from the remaining lines, preserving the original formatting and structure while removing all noise.
