Calculation Methodology & Formula
Converts raster image pixels to high-contrast monochrome representations and runs neural OCR matrix classification to detect typographical glyphs and line streams.
\text{Bitmap}(x, y) \xrightarrow{\text{Contrast / Binarize}} \text{GlyphMatrix} \xrightarrow{\text{OCR Classifier}} \text{UnicodeText}Worked Example: Receipt or Invoice Text Extraction
Extract line items and totals from a scanned invoice photo.

Expected OutputExtracted text with 96% confidence score and paragraph segmentation.
Uses browser client-side OCR workers to process pixels locally in memory without uploading confidential invoices.
Technical Constraints & Limitations
- Handwritten cursive text or highly distorted low-resolution photos (< 150 DPI) may have lower accuracy.
- Complex multi-column magazines may concatenate text across columns depending on line spacing.
Frequently Asked Questions
Are my private documents or sensitive invoices uploaded to a remote server?
No. All image parsing, pixel preprocessing, and OCR neural classification occur entirely inside your browser engine. Nothing is transmitted over the network.
What image formats work best for OCR?
PNG and lossless WebP produce the highest accuracy because they have sharp, uncompressed text edges. For camera photos (JPEG), ensure good lighting and enable the "Enhance Text Contrast" option.
Can this tool recognize non-English languages?
Yes. You can select English, Spanish, French, German, Portuguese, Italian, Chinese, Japanese, Russian, or Arabic.
