OCR German PDF
Make scanned German PDFs searchable. Handles umlauts (ä, ö, ü) and the eszett (ß) correctly. Free, 100+ languages.
German OCR's main challenges are the umlauts (ä, ö, ü, Ä, Ö, Ü) and the eszett (ß) — a uniquely German character that English-trained OCR sometimes misreads as 'B' or 'fs'. Compound German words can also be very long (up to 60+ characters in technical contexts), which trips up some segmentation algorithms. PDFOnly's Tesseract-based pipeline is tuned for these specifically.
Common use cases: digitizing legal documents from Germany, Austria, or Switzerland; processing customer scans for DACH-market support; making German academic papers searchable; or extracting German text from technical documentation. After OCR, the German text is fully searchable in any PDF reader and can feed into translation tools, search engines, or NLP pipelines.

Frequently asked questions
Will the eszett (ß) come through correctly?
Yes — Tesseract's German model recognizes ß reliably on clean scans. On poor scans it may misread as 'B' or 'fs', so re-scanning at 300 DPI gives much better results. Note: in modern Swiss German usage, ß is often replaced with ss, which Tesseract also handles correctly.
What about Austrian and Swiss German variants?
Same German language pack handles all three (Germany, Austria, Switzerland). Spelling differences are minor and Tesseract handles them uniformly.
Can I OCR mixed German + English documents?
Yes — specify both languages. Useful for German technical manuals with English code samples, academic papers with English abstracts, or bilingual contracts.
