FAQs About OCR PDF Converter
Learn more about using Lumr for online PDF text recognition and for creating searchable documents.
What is OCR in a PDF?
OCR stands for optical character recognition, which is used to identify text in scanned pages or images. This lets you search, select, highlight, and copy content that was previously stored only as an image.
Will the OCR process change the visual layout or formatting of my original document?
Lumr is designed to keep the original appearance of your PDF file while adding a searchable text layer that provides clear results as long as the document is readable.
Can I use this online OCR tool to process documents in foreign or multiple languages?
Yes, our tool’s OCR engine features global multi-language recognition supporting more than 50 languages. You can use the OCR online tool for your foreign-language and multilingual documents.
Is it safe to use the Lumr OCR tool?
Lumr uses secure online processing designed to help protect your documents during upload, OCR processing, and download. Avoid uploading highly sensitive information unless you are comfortable using an online service and have reviewed the platform’s current privacy terms.

How accurate is your OCR tool with messy handwriting or blurry scans?
