Sobre a ferramenta OCR PDF
OCR PDF converts a scanned, image-only PDF into a searchable document. A scanner produces pictures of pages, so the text in them cannot be selected, copied or found with Ctrl+F. This tool runs optical character recognition on every page and embeds the recognized text as an invisible layer positioned exactly over the printed words. The page still looks identical to the original scan, but you can now search it, copy text out of it, and document systems can index it. It processes multi-page documents in one pass and supports English and Arabic recognition, including mixed-language documents. Typical inputs are scanned contracts, old archives, printed invoices, ID documents and books photographed or scanned to PDF.

OCR PDF vs. PDF to Word for scanned files
Use OCR PDF when you want to keep the document as a PDF that looks exactly like the scan but becomes searchable - ideal for archiving, legal records and document management systems.
Use PDF to Word when you want to edit the content. That tool detects scanned pages, runs the same OCR step automatically, and then builds an editable DOCX file.
Use Image OCR (image to text) when your source is a photo or screenshot rather than a PDF, and you just want the plain text out of it.
Getting the best OCR results
Scan at 300 DPI or higher; low-resolution scans are the most common cause of recognition errors.
Keep pages straight - heavy skew or keystone distortion from phone photos reduces accuracy.
Select the correct language. Running Arabic text through English-only recognition (or the reverse) produces garbled output.
Perguntas frequentes
What does OCR actually do to my PDF?
OCR (optical character recognition) reads the printed text in the scanned page images and adds it back as an invisible text layer on top of each page. The PDF looks unchanged but becomes searchable and copyable.
Will OCR change how my PDF looks?
No. The visible page stays the original scanned image. Only a hidden text layer is added underneath, so the document prints and displays exactly as before.
Which languages does the OCR support?
English and Arabic are supported, including documents that mix both. Choose the language option that matches your document for the best accuracy.
How accurate is OCR on scanned documents?
Clean, straight scans at 300 DPI or higher of printed text give very high accuracy. Accuracy drops with blurry photos, skewed pages, handwriting or very small print.
My PDF already has selectable text - do I need OCR?
No. If you can already select and copy text in your PDF, it is a digital PDF and OCR adds nothing. OCR is only needed for scanned or photographed documents.
Can I copy text out of the PDF after OCR?
Yes. After OCR you can select and copy text directly in any PDF reader. If you want an editable document instead, use PDF to Word, which runs OCR automatically on scanned files.
the OCR tool é gratuito?
Yes. OCR processing is free, with no account and no watermark on the output.
