OCR Text Recognition
OCR text recognition in PDF online for free. Make scanned documents searchable.
A scanned PDF is just an image — you cannot search it or copy its text. With PDF.dk you OCR your scanned documents for free and make them searchable in Danish, English and several other languages — batch supported. The file is processed in the Nordics and deleted automatically when the job finishes.
Frequently Asked Questions
- What languages are supported?
- We support Danish, English, German, French, Spanish and many more languages.
- What is OCR on a PDF, and is it free?
- OCR (text recognition) makes a scanned PDF searchable by recognising the text in the image. Upload your PDF, run OCR, and download a searchable file, free and without watermark on PDF.dk.
- Will the file become searchable afterwards?
- Yes, after OCR you can search in the text and highlight/copy text from the document.
- How do I make a scanned PDF searchable?
- Upload the scanned PDF, pick the document language and click Start OCR. We add an invisible text layer on top of the scan so you can search, highlight and copy the text — while the page looks exactly as before.
- How do I copy text from a scanned PDF?
- Run OCR on it first — afterwards the text can be selected and copied like in any other document. It also works on older scans and photographed documents, as long as the text is legible.
- Can I OCR multiple PDFs at once?
- Yes, the tool supports batch processing: upload several files and they are processed one after another with the same language and quality settings. Download them individually or all at once.
- Is it safe to upload my PDF?
- Yes. The upload is encrypted, and the file only stays on our Nordic servers while the job runs. Afterwards it is deleted automatically, and we never share your data.
