Frequently Asked Questions

Everything you need to know about browser processing, file safety, and format capabilities.

How does offline OCR work without sending images to Google or AWS?

DocuShrink uses Tesseract.js compiled into WebAssembly. The neural character recognition weights run directly inside a background Web Worker on your local processor.

What scan quality is needed for high recognition accuracy?

We recommend 150 to 300 DPI for printed documents. Ensure adequate lighting, straight orientation, and minimal motion blur for optimal accuracy.

Can I copy the recognized text directly to my clipboard?

Yes. A dedicated 'Copy All' button copies extracted text with preserved line breaks instantly to your clipboard.

Is OCR completely private and secure for confidential medical or financial records?

Yes. Because execution happens 100% on-device, your confidential records never traverse any network or touch third-party cloud infrastructure.
