How to Remove Headers and Footers from PDF Text

Why repeated headers, footers and page numbers hurt AI results, and how to strip them automatically from extracted PDF text.

The hidden cost

A running header on 200 pages adds 200 copies of the same line, often splitting sentences at page breaks. Models read every copy.

Automatic cleanup

PDF to Clean Text detects lines that repeat across pages and removes them, along with standalone page numbers and hyphenation breaks. If you need headings preserved, use PDF to Markdown.

Spot-check results

Look at a few page boundaries in the output. Sentences should flow across pages without a stray title or number in the middle.
