Supports Multi-page PDF, PNG, JPG, JPEG, and WEBP (Up to 50MB)
100% Client-Side In-Browser Sovereign OCR Guarantee
All optical character recognition calculations, pixel scanning, character segmentation, and bounding box computations run purely inside your local browser sandbox via WebAssembly (WASM) and isolated Web Workers. No image bytes, PDF streams, or extracted text are ever transmitted to any remote server or third-party cloud. Safe for confidential tax forms, government IDs, invoices, and private financial ledgers.
Comprehensive Technical Guide & Reference
Upload any multi-page PDF or image (PNG, JPG, WEBP), select your target language (e.g. English, Tamil, Hindi, Spanish, German, French), adjust the confidence filter threshold, and extract clean plain text, structured JSON bounding box coordinates, or reconstructed CSV table rows.
11. 100% In-Browser Optical Character Recognition (Zero Data Leakage)
Unlike legacy OCR web converters that upload sensitive files to remote third-party cloud servers where data might be logged or stored, our engine loads the complete Tesseract neural OCR engine directly inside your browser via WebAssembly (WASM). Your confidential files never leave your device.
22. Heuristic Spatial CSV Table Reconstruction
Extracting tabular data from scanned receipts and bank statements is simplified through spatial clustering. The engine groups word bounding boxes by horizontal line baselines and vertical column gaps to reconstruct structured CSV tables ready for Excel or Google Sheets.
33. Confidence Threshold Filtering & Accuracy Optimization
Every recognized word is accompanied by a statistical confidence score (0% to 100%). You can dynamically filter out noisy artifacts, low-contrast watermarks, or unconfident character scans with the real-time threshold slider.
44. Multi-Language & Indic Script Support
Equipped with specialized trained models for Latin scripts (English, Spanish, German, French, Portuguese, Italian), Indic languages (Tamil, Hindi, Kannada, Telugu, Malayalam, Bengali, Marathi, Gujarati), and CJK scripts (Japanese, Simplified Chinese).
Frequently Asked Questions
Never. The entire optical character recognition engine runs strictly inside your local web browser's WebAssembly sandbox. If you disconnect your internet after the page loads, the OCR process still runs offline.
