Umi-OCR is a free, open-source, fully offline OCR application for Windows and Linux with a Qt/QML GUI. It supports screenshot OCR, batch image recognition, PDF text extraction and searchable PDF generation, QR code scanning/generation, and CLI/HTTP interfaces for external calls.
Use cases
- extract text from screenshots offline
- batch OCR a folder of images
- convert scanned PDFs to searchable PDFs
- recognize text without sending data to the cloud
- scan or generate QR codes
- call OCR from scripts via command line or HTTP API
- ignore watermarks and headers/footers when recognizing documents
When to choose
- you need offline, privacy-preserving OCR on Windows or Linux
- you want batch processing of images or PDFs with layout handling
- you need an HTTP or CLI OCR service for automation
When to avoid
- you need a library to embed in your own Python/JS code rather than a standalone app
- you need macOS or mobile support
- you need cloud-scale or GPU-cluster OCR throughput
