Scanned PDFs and image-based PDFs are essentially pictures of text — you cannot search for words, select text, or copy content from them. OCR (Optical Character Recognition) fixes this by analyzing the images and adding a text layer, making the PDF fully searchable and copyable. CocoPDF uses a high-accuracy OCR engine to do this.
Select the primary language of your document (English, French, Spanish, German, or Arabic) before processing. Language selection significantly affects accuracy because the OCR engine uses language-specific character frequency models to interpret ambiguous characters. An English document processed with the Arabic language model will produce poor results and vice versa.
The OCR process adds an invisible text layer beneath the visible page images. The document still looks exactly the same, but now contains real, machine-readable text that any PDF reader can search. Upload your scanned PDF, select the language, and click Process. Your searchable PDF downloads immediately — files deleted within one hour, no watermarks added.

Frequently Asked Questions
What is OCR and why do I need it?
OCR (Optical Character Recognition) converts images of text into actual machine-readable text. Scanned PDFs are just images — you cannot search, copy, or edit the text. After OCR, the PDF contains real text that any PDF reader can search and you can copy.
Which languages are supported?
English, French, Spanish, German, and Arabic. Select the primary language of your document before processing for best accuracy. Mixed-language documents may have reduced accuracy.
Does the OCR tool change how the PDF looks?
The visual appearance of the PDF is preserved. OCR adds an invisible text layer beneath the visible page image, so the document looks the same but becomes searchable.
What if the OCR accuracy is poor?
OCR accuracy depends on the scan quality. High-contrast, 300+ DPI scans produce excellent results. Low-quality scans, handwriting, and unusual fonts reduce accuracy. Ensure your scan is straight and clear before processing.
