## What is PDF Indexer?

PDF Indexer turns a separate title-to-page mapping into fast navigation for a PDF.

Choose a PDF, add its index, and search titles across your library. On import, the app divides the PDF into private on-device sections at indexed title pages and removes its temporary full-size copy. A result opens only the matching section at the mapped PDF page. Page offsets handle documents whose printed page numbers do not match their PDF positions.

Import mappings from CSV, JSON, XLSX, pasted text, or manual entry. Review validation warnings before saving, correct individual rows later, replace a mapping without copying the PDF again, and export a mapping as CSV or JSON.

PDF Indexer is local-first. It needs no account and has no publisher-operated analytics or app-run cloud service. Your app library stays in private device storage unless you choose to export a mapping. The free app may show non-personalized banner ads after any required privacy choices. PDFs, mappings, titles, and searches are not sent to the ad service. See the Privacy Policy for operating-system backup details.

Highlights:

• Search across multiple indexed PDFs
• Exact, prefix, substring, and alias matching

• Page-offset calibration and bounds validation
• Mapping correction, replacement, and export
