OCR PDF Online Free – Make Scanned PDFs Searchable

OCR PDF — add a real text layer to scanned pages

OCR PDF solves a different problem than repair or compress: the file already opens, but Ctrl+F finds nothing and you cannot highlight a sentence. That usually means the pages are pictures of text. Optical character recognition reads those pictures and writes a searchable text layer into a new PDF — free on pdfLaunch.

Use this after a phone scan, a flatbed export, or a repaired file that became image-based. Do not confuse OCR with PDF to Word (editable DOCX) or with capturing paper via Scan to PDF.

What “searchable PDF” means in practice

Find words with Ctrl+F / ⌘F

Jump to a clause, invoice number, or name inside a 40-page scan instead of scrolling page by page.

Copy quotes accurately

Select text in the reader and paste into email, notes, or a ticket — without retyping from a photo of the page.

Archive & e-discovery friendly

Searchable PDFs index better in drives and DMS tools that rely on embedded text, not pixels alone.

Language-aware recognition

Pick English, Dutch, German, French, Spanish, Italian, Portuguese, Turkish, Polish, Russian — or auto-detect — before you run OCR.

How to OCR a PDF here

📤

1

Upload the scanned PDF

Choose a file up to 100 MB from your device or cloud. Clear, upright pages OCR better than blurry angled shots.

🔤

2

Pick a language and run OCR

Select the document language (or auto-detect) and click Run OCR. Processing happens on our servers with OCRmyPDF / Tesseract so recognition stays strong on multi-page scans.

3

Download the searchable PDF

Open the result and try searching for a known word. Temporary processing files are removed when the job finishes.

Documents that need OCR most

📷 Phone scans of contracts — search for “termination,” “liability,” or a party name before the meeting.

🏦 Bank / tax PDFs from scanners — copy IBAN or reference numbers without typing errors.

🏫 Lecture printouts & worksheets — make study packs searchable for revision.

🏛 Government forms photographed as PDF — find field labels and instructions quickly.

🔧 After Repair PDF — if recovery produced image pages, OCR puts text back within reach.

OCR vs similar tools — pick the right job

→ OCR (this page): keep a PDF, but add searchable/selectable text on scanned pages.

→ PDF to Word: you need an editable DOCX to rewrite content, not just search inside a PDF.

→ Repair PDF: the file will not open cleanly. Repair first, OCR second if needed.

→ Scan to PDF: you still have paper in hand and need to capture pages before OCR.

Tips for better accuracy: straighten pages with Rotate / Organize, crop heavy margins if your capture tool allows, and choose the correct OCR language. Compress afterward only if the searchable file must meet an upload cap.

🔒

OCR needs a short server pass — here’s what that means

Unlike merge/split in the browser, strong multi-page OCR runs on the server

HTTPS upload: your PDF is sent encrypted for OCRmyPDF / Tesseract processing.
Job-scoped files: working copies are deleted when the OCR job completes (success or failure).
No account required: run OCR without creating a login. Cloud import is optional.
Language is your choice: you control which recognition pack is applied before processing starts.

OCR PDF FAQ

How do I make a scanned PDF searchable?

Upload the PDF, choose the document language (or auto-detect), click Run OCR, then download the new file and test Ctrl+F on a word you can see on the page.

Will OCR let me copy text from the PDF?

Yes — that is the point of a text layer. Accuracy depends on scan quality, fonts, and the language you select.

Which languages are supported?

English, Dutch, German, French, Spanish, Italian, Portuguese, Turkish, Polish, Russian, plus an auto-detect option in the language menu.

How large can the PDF be for OCR?

Up to 100 MB. Very long scans take longer because every page is recognized.

My PDF already has some text — should I still OCR?

If mixed pages include image-only scans, OCR can still help. If the whole file is already born-digital text, you may not need it.

Is OCR the same as converting to Word?

No. OCR keeps a PDF and adds searchable text. PDF to Word aims for an editable document you can rewrite in Word.

Do you keep my PDF after OCR?

Temporary files used for the job are deleted when processing finishes. We do not build a permanent library of your uploads.

Why are some words wrong after OCR?

Blur, skew, tiny fonts, stamps, and handwriting lower accuracy. Reshoot or straighten pages, pick the right language, and re-run OCR on a cleaner file.

Should I OCR before or after compress?

Prefer OCR on a readable scan first. Heavy compression before OCR can smash fine print and hurt recognition.

Is a pdfLaunch login required for OCR?

No. Upload, run OCR, and download without registering.
