Image to Text (OCR)

How OCR (Optical Character Recognition) Works

Toolkiya's image-to-text tool uses Tesseract.js, an open-source OCR engine that runs entirely in your browser using WebAssembly. When you upload an image, the engine analyzes the visual patterns of characters, compares them against trained language models, and extracts the text content.

The OCR process handles multiple languages, various fonts (including handwriting to some degree), and different image qualities. It works best with clearly printed text on high-contrast backgrounds. All processing happens locally — your images and the extracted text never leave your device.

When to Extract Text from Images

Copying text from screenshots when you cannot select the text directly. Extracting information from scanned documents, receipts, or business cards. Converting photographed notes or whiteboard content to editable text. Pulling data from images of tables, invoices, or forms. Digitizing printed or handwritten text for archiving or editing.

Why Use Toolkiya for OCR

Google Lens and online OCR tools upload your images to cloud servers for processing. For images containing personal information — IDs, bank statements, medical records — this creates a privacy risk.

Toolkiya's OCR runs entirely in your browser. Your images are processed locally using your device's computing power, and neither the image nor the extracted text is ever sent to any server. The tool is free, unlimited, and requires no account.
