What is OCR and what does it do to my PDF?

OCR (Optical Character Recognition) reads text from scanned or image-based PDFs and adds an invisible searchable text layer. Your PDF keeps its original appearance while allowing you to search, select, and copy text.

Which languages does AziPDF OCR support?

AziPDF OCR supports 100+ languages including English, Hindi, Arabic, Chinese, French, German, Spanish, Japanese, Korean, and many more. You can select up to 3 languages per conversion for mixed-language documents.

Will OCR change how my PDF looks?

No. OCR only adds an invisible text layer beneath your original content. The visual layout, images, fonts, and colors are completely unchanged.

Can I OCR multiple PDF files at once?

Yes. Upload multiple PDF files and AziPDF processes each one automatically. When you upload more than one file, the results are packaged into a ZIP archive for download.

How accurate is the text recognition?

OCR accuracy depends on the quality of the original scan. Clear, high-resolution documents usually produce the best results. AziPDF applies image preprocessing to help improve text recognition.

Can I OCR scanned PDF files?

Yes. AziPDF is designed to recognize text in scanned and image-based PDF files, making them searchable, selectable, and easier to copy.

Can I OCR PDF files on mobile devices?

Yes. AziPDF OCR works on Android phones, iPhones, tablets, laptops, and desktop computers using modern web browsers.

What types of PDFs work best with OCR?

Scanned documents, books, invoices, receipts, and other image-based PDFs benefit most from OCR. If your PDF already contains searchable text, OCR is usually unnecessary.
