Make a scanned PDF searchable with OCR
OCR (Optical Character Recognition) converts scanned pages into selectable, searchable text. Upload a PDF scan to create a text layer so you can copy, search, and index content.
If your PDF is already searchable, the tool will detect it and you can download the original without changes. This avoids unnecessary processing.
After OCR, you can compress the file for sharing, convert it to Word/TXT, or flatten it for consistent rendering across devices.
FAQ
What does OCR do on a PDF?
It adds a searchable text layer by recognizing characters on scanned pages, while keeping the original page images.
Will OCR change the layout of my document?
No. OCR keeps the visual layout the same and only adds text data on top of the pages.
Why does it say OCR is not needed?
Because the inspection detects that your PDF already contains selectable/searchable text.
Can I copy text after OCR?
Yes. Once processed, you can search, select, and copy text in most PDF viewers.
Does OCR improve search and indexing?
Yes. Search works inside the PDF, and in many cases text becomes indexable for internal document search tools.
What should I do after OCR?
Common next steps are compressing the PDF, converting to Word/TXT, or flattening for consistent viewing.
