How to Search Inside Scanned PDFs

A scanned PDF is often just a picture of text. To search inside it, the document needs OCR: optical character recognition. OCR reads the words in the image and makes them searchable.

Searchable scans are much more useful than image-only files. You can find a policy number, date, address, clause, receipt total, or name without opening every page by hand.

Where to start

Use OCR for paper letters, contracts, receipts, medical documents, statements, school forms, and any scan that you may need to search later.

A simple workflow

1. Scan the document clearly with good lighting and straight page edges.
2. Run OCR or use a scanner that applies OCR automatically.
3. Test search with a word you can see on the page.
4. Name the file clearly even if the text is searchable.
5. Store the searchable PDF in the right folder.

Common mistakes to avoid

• Scanning blurry pages and expecting OCR to fix them.
• Relying only on OCR when file names are still meaningless.
• Forgetting handwritten notes may not be recognized accurately.
• Assuming every old scan is searchable.
