# OCR PDF for developers

_Updated July 2026 · Arthize · https://arthize.com/for/developers/ocr-pdf_

Arthize lets software developers 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 developers OCR a scanned PDF

A developer converts a Markdown spec to a clean PDF for a stakeholder, extracts text from a vendor PDF to parse it, and archives the release notes as PDF/A.

**Built for technical docs.** Whether it's technical docs, specs, README files, Arthize's ocr pdf keeps the work inside your private workspace. Internal specs and unreleased docs are confidential; a private workspace keeps them off public converters.

## 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.
