How to Make a Scanned PDF Searchable and Copy Its Text (OCR)
By the DocEpic team · Updated · 3 min read
A scanned PDF looks like a document but behaves like a photo: you can't search it, can't select a sentence and can't copy a number out of it. OCR — optical character recognition — reads the letters in the image and turns them into real text. This guide shows how to make a scanned PDF searchable, how to get text out of a single photo, and what to do with PDFs that won't open.
How to tell if a PDF is scanned
Open the PDF and try to select a word or search for one with Ctrl+F (on a phone, use the reader's search). If nothing is found, or the whole page gets selected as one block, the page is an image and needs OCR.
Make a scanned PDF searchable
OCR PDF reads every scanned page and lays an invisible text layer exactly over it. The page looks the same as before, but you can now search, select and copy the text.
- Open OCR PDF and add your scanned PDF.
- Choose the language of the text — English, Hindi, Marathi, Bengali, Tamil, Telugu and more. For a page that mixes Hindi and English, choose both.
- Choose Standard for normal documents, or High for small print such as bank statements. Tick Skip pages that already have text for PDFs that are only partly scanned.
- Run it and download the searchable PDF — and, if you like, the text as a .txt file too.
OCR runs in your browser, so your documents are never uploaded. Large documents take a few seconds per page.
Get the text from a single photo
For a photo or screenshot rather than a PDF — a notice on a board, a page from a book, a screenshot of a message — Image to Text reads the text and shows it ready to copy, or as a .txt or Word file. It works best on clear, straight photos of printed text; handwriting is rarely read well. Always check names and numbers against the original, as OCR can confuse similar-looking characters such as 0 and O.
A PDF that won't open
A PDF that was only partly downloaded, or saved by a buggy program, may refuse to open or show blank pages. Repair PDF rebuilds the file's internal structure and can often bring it back. It can't recover pages that are missing from the file altogether, so try downloading the original again if the repaired copy is incomplete.
Archiving documents for the long term
Some courts, universities and offices ask for PDF/A, a version of PDF made for long-term archiving: every font is embedded and nothing depends on outside resources, so it will open the same way decades from now. PDF to PDF/A converts a PDF to PDF/A-2b, the recommended level, or to PDF/A-1b or 3b if you are asked for those.
Questions people ask
Can OCR read Hindi?
Yes. Choose Hindi as the language; for text that mixes Hindi and English, choose both. Clear, printed text gives the best results.
Will OCR change how my PDF looks?
No. The original page is kept exactly as it was; an invisible text layer is added on top so you can search and copy.
Can it read handwriting?
Only rarely and roughly. OCR is made for printed text; for handwriting, typing is usually faster.
Are my scanned documents uploaded?
No. OCR PDF and Image to Text run in your browser. Repair PDF and PDF to PDF/A run on our server and delete the file right after.
