Skip to contentOCR scanned PDFs, convert images to searchable PDF and extract text — browser-first where WASM is supported.
OCR Scan Studio is built for digitizing paper: run OCR on all pages, merge scans, compress output and export text. Unlike cloud OCR services, standard modes keep files on your device. Browse related Tentaco tools on this hub, open a studio mode when you need a fuller workspace, and keep files on your device whenever the tool runs locally.
