Make Scanned PDFs Searchable
If your PDF is a scan, it's often just an image — so you can't highlight text or search for words. OmnisPDF OCR recognizes the text and creates a searchable PDF you can use like a normal document.
Extract Text From PDF Scans
Need the words from a scanned document? OCR pulls text from image-based pages so you can copy and paste content into notes, email, Word, or a TXT file.
Works on Receipts, Forms, Contracts, and Invoices
OCR is especially useful for paperwork and archived documents where you need to search, find keywords, or reuse text quickly.

Frequently Asked Questions
What is OCR for PDFs?
OCR (Optical Character Recognition) detects text inside scanned or image-based PDFs and converts it into selectable, searchable text.
When do I need OCR instead of PDF to TXT?
If the PDF is a scan and you can't highlight text, you need OCR. If the PDF already contains selectable text, a normal PDF to TXT conversion may be faster.
How accurate is OmnisPDF OCR?
Accuracy depends on scan clarity, resolution, and font. Clean, high-resolution scans produce the best results. Blurry or skewed scans reduce accuracy.
What languages does the OCR Scanner support?
The OCR Scanner supports 16+ languages including English, Spanish, French, German, Portuguese, Italian, Dutch, and more.
Is it safe to upload scanned documents?
Yes. All transfers are SSL encrypted and your files are deleted immediately after your session. We never store or share your documents.
What is the maximum file size I can OCR?
Pro accounts can upload files up to 200MB. Business accounts can upload files up to 1GB.
