Scanned PDF to PDF – OCR a Scan into a Searchable PDF
How do you convert a scanned PDF to a searchable PDF?
Converting a scanned PDF to PDF with real text means running OCR (optical character recognition) on each page image, so the words become characters you can search, select and copy. A scan is only a picture of a page: Ctrl+F finds nothing and you can't copy a single line. Linnk's OCR PDF tool reads every page with AI models (Linnk uses ChatGPT, Claude and Gemini models), rebuilds the page as structured text and writes a new, text-based PDF. Photos, logos, stamps and signatures are cropped from the scan and placed back in position. To be plain about it: this is not an invisible text layer laid over your original image. The PDF is rebuilt, so it looks close to the original rather than pixel-identical. On a faded, stained or crooked scan that is often the better outcome, because the text comes out clean and straight instead of inheriting the blur. Numbers, dates and IDs are copied digit for digit, and anything the OCR can't read is marked rather than guessed. A quick look over faint or curled pages is still a good idea.

How to convert a scanned PDF to PDF you can search
Three steps from a page image to a PDF with real text.
Upload the scan
Drop a scanned PDF, or a JPG, PNG, WEBP, HEIC or HEIF photo of a page; a photo counts as a one-page scan. Searchable PDF is already selected as the output, and the text stays in its original language.
Let the OCR read each page
AI models read every page image and rebuild it as text, usually in under a minute per page. The page shows an estimate in minutes while it works, and the first pages are free to preview without an account.
Download the searchable PDF
Sign up free to download the searchable PDF. Markdown, plain text and a layout spreadsheet come from the same conversion, and a Word file can be built on request in a few extra minutes.
What this OCR PDF tool does
Built for scans, faxes and phone photos, where there is no text to begin with.
Real text, not a picture of text
Every word in the new PDF is an actual character. Ctrl+F finds it, you can select and copy a paragraph, and your document search can index the file.
Photos, stamps and signatures put back
Images on the page are cropped from the scan and placed back in position, so a signed agreement usually still shows its signature and a certificate keeps its seal.
Clean text from tired scans
Because the page is rebuilt rather than traced over, a crooked, faint or coffee-stained scan typically comes out as straight, readable text. Very blurred pages may still need a quick check.
Numbers copied digit for digit
Amounts, dates, IDs and reference numbers are copied digit for digit. A digit the OCR can't make out is marked with a question mark, and an unreadable passage is marked [illegible], so nothing is quietly guessed.
More formats from the same run
One conversion also gives you Markdown, plain text and a layout spreadsheet with one sheet per page. Need Word? It is built on request and usually takes a few minutes.
Keep the language, or translate it
The output keeps the document's original language by default. Switch Keep original to Translate to… and the searchable PDF comes back in another language from the same run.

Ways to OCR a scanned PDF, compared
How Linnk's approach differs from the usual routes to a searchable PDF, including where the others do better.
| Feature | Linnk OCR PDF | Desktop PDF editors | Free online OCR sites | Scanner app OCR |
|---|---|---|---|---|
| How the text gets into the PDF | Page rebuilt as real text | Usually a hidden text layer under the scan | Usually a hidden text layer; varies by site | Text layer or a separate text export |
| How the page looks afterwards | Close to the original, not pixel-identical | Original scan image kept as is | Original scan image kept as is | Original photo kept, often cropped and flattened |
| Faded or crooked scans | Comes out as clean, straight text | Visible page stays as scanned | Visible page stays as scanned | Some apps straighten the photo |
| Unreadable text | Marked [illegible] or with a question mark | Varies | Varies | Varies |
| Other outputs | Word, Markdown, plain text, layout spreadsheet | Often Word and other exports | Varies, often Word or text | Usually PDF or text |
| Where it runs | Browser, nothing to install | Installed software, usually paid | Browser | Phone app |

Who makes scanned PDFs searchable
Anyone who has to find something inside a document that was scanned instead of typed.
Lawyers and paralegals
OCR scanned contracts, court filings and discovery bundles so a clause, a date or a party's name turns up with a search instead of a page-by-page read.
Office and records teams
Turn folders of scanned letters, invoices and forms into searchable PDFs that a shared drive or document system can actually search.
Researchers and students
Copy quotes from scanned book chapters, archive papers and old theses instead of retyping them, with the page images still in place.
Accountants and bookkeepers
Search scanned statements and receipts for an amount or a reference number; figures are copied digit for digit from the page.
HR and admin staff
Keep signed offer letters and onboarding forms as searchable PDFs, with the signatures still visible on the page.
Anyone with a phone scan
Snap a letter, a notice or a form with your phone and get back a PDF you can search and copy from, not just a photo.
