Copy text from screenshots, images, and PDFs with private OCR that runs entirely on your device. Turn text trapped inside screenshots, images, scanned documents, and PDFs into editable, copyable text—without uploading your files anywhere. Unlimited OCR is a free, private, and open-source OCR reader that processes everything directly on your device. Unlike cloud OCR services, it requires no account, API key, subscription, or usage credits.

It can continue working offline because recognition does not depend on an external OCR service. USEFUL FOR • Copying text from screenshots and images • Reading scanned PDF documents • Extracting error messages from screenshots • Digitizing printed documents and receipts • Reusing text from research papers or archived documents • Working with confidential business documents • Translating printed text in another language • Making inaccessible visual text editable and searchable WHY INSTALL UNLIMITED OCR? Most online OCR tools require you to upload potentially sensitive documents to their servers and may impose file, page, or usage limits. Unlimited OCR keeps the complete process on your device, gives you unlimited scans, and lets you inspect its open-source code. The extension uses temporary access only when you ask it to capture the current tab. It does not continuously read or monitor the websites you visit. Unlimited OCR works best with clear printed text. Handwriting, mathematical formulas, complex tables, and heavily distorted images may require manual correction. Free. Private. Open source. No account required.
