Frequently asked questions
- What is OCR and why do I need it?
- Optical Character Recognition reads text from scanned images and makes it selectable and searchable. Scanned PDFs without OCR are essentially images — you cannot search or copy their text.
- How accurate is the OCR?
- Very high for clean, well-lit scans of printed text. Handwriting, unusual fonts, low-resolution scans, and complex layouts may produce errors.
- Which languages does OCR support?
- 100+ languages including English, French, German, Spanish, Russian, Chinese, Arabic, Japanese, and many more.
- Will OCR increase my PDF file size?
- Yes — OCR adds a text layer on top of the existing scanned images. Expect a modest size increase.
- How long does OCR take?
- A 10-page scan typically takes 30–60 seconds in the browser depending on resolution and device speed.
