Can batch text extraction make legacy PDF archives searchable?

Yes, for PDFs that were originally created as native digital documents. If your archive contains scanned PDFs, those require OCR processing first to generate the text layer before extraction is possible.

How do I know which archived PDFs have selectable text?

Try selecting and copying text in your PDF viewer. If you can highlight and copy text, the document has an embedded text layer and will extract successfully. If you can only select the whole page as an image, it is a scanned PDF.

What output format works best for importing into a records management system?

Per-file output is typically best for records management imports, as it preserves the one-to-one relationship between each source PDF and its text file. Combined output is better for building search indexes where document boundaries are handled by the indexing tool.

Is there a batch size limit for archive processing jobs?

Up to 50 files or 2 GB per batch, whichever limit is reached first. For large archives, process in sequential batches of 50 to work through the full collection.

Extract Text from Archived PDF Collections for Searchable Indexing

Document archives containing years of PDF records are only as useful as their searchability. When archived PDFs cannot be full-text searched, staff must open documents individually — making retrieval slow and important records effectively invisible. Deliteful extracts embedded text from up to 50 archived PDFs per batch, producing the plain-text layer that powers searchable indexes and records management systems.

Organizations migrating legacy document archives to new records management platforms frequently discover that their PDF files lack the text layer needed for full-text search. Extracting text from the archive in batches — processing 50 files at a time — is the most practical path to making these records searchable without a full OCR project. For PDFs that were originally created digitally (not scanned), extraction is immediate and complete.

The combined output mode produces a single file containing all extracted text with per-document separators, which is the correct input format for building a search index or importing into a document management system. Per-file output maps to archives that maintain document-level metadata, where each record is indexed individually. Deliteful handles batches up to 2 GB total, covering hundreds of documents in a single job.

How it works

1
Select archive PDFs for the batch
Add up to 50 PDFs from your document archive — policies, records, filings, or any native digital PDFs requiring text extraction.
2
Choose index-ready output format
Combined file for bulk index import, or per-file for document-by-document records management workflows.
3
Integrate with your records system
Feed the extracted .txt files into your records management platform, SharePoint, or search index to enable full-text retrieval.
