Will OCR change the appearance of my scanned contract?

No. The original scanned image is preserved exactly. OCR adds an invisible text layer underneath the visual content, so the document looks identical but becomes searchable and copy-paste enabled.

Can I run OCR on a contract that has both scanned and digital pages?

Yes. Deliteful automatically skips pages that already contain a searchable text layer, so mixed-content PDFs process safely without duplicating text on digital pages.

How accurate is the OCR on legal documents?

Accuracy depends heavily on scan quality and resolution. Clean, high-resolution scans of typed contracts typically achieve very high accuracy. Handwritten annotations and low-quality fax scans will produce lower accuracy, which is a limitation of OCR technology generally.

Is fast mode suitable for legal work?

Fast mode trades some accuracy for speed. For contracts where you need to locate and copy specific clause language, standard mode is recommended. Fast mode is useful for quickly making a large archive broadly searchable when exact text fidelity is less critical.

Make Scanned Contracts Searchable with OCR

Scanned contracts are litigation time bombs — you cannot Ctrl+F a clause you cannot see. Deliteful's OCR tool adds a hidden text layer to your scanned PDFs, making every party name, date, and indemnification clause instantly searchable without altering the visible document.

Contract lawyers routinely inherit PDF bundles from clients — executed agreements scanned at closing, faxed amendments, notarized addenda — none of which are machine-readable. Searching a 200-page scanned agreement for a specific limitation-of-liability clause means scrolling every page manually. OCR eliminates that. A searchable text layer means Ctrl+F works, your PDF reader's bookmark index works, and downstream review tools like contract analytics platforms can ingest the document properly.

Deliteful runs Tesseract-based OCR tuned for legal document formats. You select the document language (English, French, Spanish, German, Italian, Portuguese), upload your scanned PDFs, and receive output files with the original scan preserved visually and a hidden text layer added beneath. Pages already containing selectable text are skipped automatically, so mixed-content bundles process cleanly. Fast mode is available when speed matters more than marginal accuracy gains.
