OCR tools split between engines you run yourself and websites where you drop a file. Tesseract is the foundation: an Apache-2.0 engine with over 100 languages, but a command-line tool with no graphical interface. OCRmyPDF wraps it to add a searchable text layer to scanned PDFs and needs Tesseract and Ghostscript installed. NAPS2 gives a scanner interface with OCR in over 100 languages and saves PDF, TIFF, JPEG or PNG. PaddleOCR is a Python toolkit that returns structured JSON or Markdown and suits developers processing many documents. For one-off jobs, NewOCR is free with unlimited uploads and no registration, and OnlineOCR.net allows guests 5 files per hour up to 15 MB, with 50 free pages after registration. The trade-off is privacy and quality against effort. Online services are the fastest, but you upload the document to someone else's server, which is a poor idea for contracts or IDs. Local engines keep files private but need installation, and Tesseract output is only as good as the scan, so a straight, 300 dpi image matters more than the choice of tool. Check your language and layout before you commit, as multi-column pages and tables are where free OCR usually stumbles.
