Arthize lets students 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 students OCR a scanned PDF

The night before a deadline, a student merges lecture slides with their notes, compresses a scanned reading under the portal's 10MB limit, and annotates the key pages for revision — free, with no watermark on the result.

**Built for lecture slides.** Whether it's lecture slides, readings, assignments, Arthize's ocr pdf keeps the work inside your private workspace. Students often work on shared or library computers; a tool that processes files privately and deletes them keeps coursework and ID scans out of strangers' hands.

## 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.
