# PDF Editing Skill

## CRITICAL RULES - READ FIRST

**NEVER DO THESE:**
- NEVER use strikethrough lines to cross out text
- NEVER rasterize or flatten the PDF to images
- NEVER convert PDF pages to PNG/JPG and draw on them
- NEVER use pdf-to-image-to-pdf workflows
- NEVER use add_redact_annot() with BLACK fill (use WHITE fill instead)
- NEVER add text NEXT TO old values - REPLACE them at the SAME position

**TWO APPROACHES - CHOOSE THE RIGHT ONE:**
