How Does Local Browser OCR Work?
Our Vision OCR tool uses Tesseract.js, a powerful OCR engine that runs entirely in your browser using WebAssembly. Here's the process:
- Upload Image: Select your image containing text (screenshots, documents, photos, scanned papers).
- Local Processing: The OCR engine loads and processes your image entirely on your device.
- Text Extraction: Advanced algorithms convert pixels to editable, searchable text with high accuracy.
- Get Results: View, copy, or listen to your extracted text instantly.
Why Local OCR is Better for Privacy
Unlike cloud-based OCR services that upload your images to remote servers, our local OCR:
- Never Uploads Your Images: Your files stay on your device at all times.
- No Data Collection: We don't track what you scan or extract.
- Works Offline: After initial load, works without internet connection.
- No Account Required: Complete privacy with zero registration.
- Unlimited Usage: No daily limits or premium tiers.
This makes it ideal for sensitive documents like contracts, medical records, financial statements, and confidential business materials.

Frequently Asked Questions
Q: Is my data really private?
A: Yes, absolutely. Our OCR runs entirely in your browser using WebAssembly technology. Your images are never uploaded to any server - all processing happens locally on your device.
Q: Can it read handwritten text?
A: Tesseract.js can recognize handwritten text, though accuracy varies based on handwriting clarity. Neat, consistent handwriting achieves better results than cursive or messy writing.
Q: Why is the first scan slower?
A: The first scan downloads the OCR language model (~4MB). Subsequent scans in the same language are much faster as the model is cached in memory.
Q: Does it work offline?
A: After the initial page load and first scan (which downloads the language model), the OCR can work offline.
