Why it matters

Extracting text from receipts, book pages, and ID cards often requires sending private, sensitive documents (containing addresses, financial totals, or personal identity numbers) to remote cloud OCR servers. This tool processes your images 100% locally on your computer using client-side JavaScript, guaranteeing total privacy and zero data leakage.

When to use it

Use when digitizing paper receipts for expense reports, extracting text from scanned PDF screenshots, pulling contact info from business cards, or reading unselectable text from images.

Common questions

Does my image get uploaded to any server?

No. The entire OCR and image processing pipeline executes locally inside your web browser using the HTML5 Canvas API and JavaScript. Your image never leaves your device.

How can I improve extraction accuracy on blurry images?

Use the Pre-Processing controls: adjust the Binarization Threshold slider to separate text clearly from background noise, or toggle 'Invert Colors' if you are extracting white text printed on a dark background.

What entity types can the pattern extractor identify?

The built-in regex entity extractor automatically scans the OCR output to isolate email addresses, telephone numbers, currency amounts ($/€/£), and website URLs.

What image formats are supported?

All standard web image formats supported by modern browsers are compatible, including PNG, JPEG/JPG, WebP, GIF, and SVG.
