Umi-OCR is a free, open‑source OCR tool that runs offline and supports screenshot, batch image, and PDF recognition. It offers a GUI built with Qt/QML as well as command‑line and HTTP interfaces for integration.
Use cases
- Extract text from screenshots on Windows or Linux
- Batch process a folder of images to obtain searchable PDFs
- Remove watermarks or headers from scanned documents
- Generate or read QR codes from images
- Integrate OCR into scripts via the CLI or HTTP API
When to choose
- You need an offline OCR solution with no network dependency
- You prefer a free MIT‑licensed tool with a graphical interface and CLI
- You work on Windows or Linux and want multi‑language support
When to avoid
- You require cloud‑based OCR scaling or advanced AI models not bundled with Umi-OCR
- You need native macOS support out of the box
- You need a tightly integrated SDK for custom application development
