OCR PDF for researchers
Updated July 2026
Arthize lets researchers and academics OCR a scanned PDF in a private workspace — free, with no watermark. OCR adds a searchable text layer to a scanned PDF, turning a picture of text into words you can select, search, copy and convert.
Why researchers OCR a scanned PDF
A researcher merges a paper with its appendices, extracts a results table into Excel for re-analysis, and compresses the figure-heavy submission under a journal's upload limit — privately.
Built for papers. Whether it's papers, datasets, appendices, Arthize's ocr pdf keeps the work inside your private workspace. Unpublished work and grant applications are confidential; a private workspace keeps them out of public tools.
What matters when you OCR a scanned PDF
OCR adds an invisible, selectable text layer over the scanned image.
Without OCR, a scanned PDF is just a picture and can't be searched.
Running OCR first is what makes a scan convert cleanly to Word or Excel.
