Start with document sensitivity
PDFs can contain contracts, invoices, customer reports, product plans, school records, or legal correspondence. Before choosing any extractor, decide whether the document should leave your device at all. If direct browser extraction works, it can reduce unnecessary transfer for documents that only need copyable text.
Confirm the PDF has a text layer
Open the PDF in a normal reader and try selecting a sentence. If the text can be selected, a browser extractor can usually read it. If selection only draws a box around an image, the file is probably a scan and requires OCR.
Expect plain text, not layout
A PDF is designed for fixed pages. The text layer may store paragraphs, columns, tables, headers, and footers in an order that does not match visual reading order. Use extracted text for search, notes, and drafts, but keep the original PDF for page references and final quotations.
Check numbers and citations manually
When a document contains prices, dates, legal clauses, study results, or page references, verify those details against the original. Extraction errors are usually small, but small errors can change meaning.
Remove repeated page artifacts
Headers, footers, page numbers, and watermarks can appear between paragraphs in extracted text. Clean these only after you understand whether they are document artifacts or meaningful content.
Use OCR only when required
OCR is useful for scanned documents, but it introduces its own recognition errors and may require upload-based processing. Use direct local extraction first for text-based PDFs, then move to OCR only when the text layer is missing.
