How Client-Side WebAssembly OCR Works

Lanternbrowsetral redefines image text recognition by replacing traditional cloud API processing with high-performance local WebAssembly execution. Your sensitive documents never leave your browser hardware.

1. Memory-Isolated Canvas Decoding

Upon drag-and-drop or clipboard paste, your image is rendered in-memory onto an isolated HTML5 Canvas. JavaScript extracts raw image pixels directly without initiating external HTTP uploads.

2. WebAssembly Tesseract Recognition

Our localized engine executes compiled C++ Tesseract OCR algorithms via WebAssembly (WASM). It performs binarization, line segmentation, and neural shape matching against full language dictionary models.

3. Structured Data Export

Character patterns are instantaneously compiled into structured text, complete with word counts and confidence metrics. Export your results directly to raw .TXT files or machine-readable .JSON structures.

Privacy Policy

Effective Date: January 1, 2026 | Platform Domain: Lanternbrowsetral.com

At Lanternbrowsetral, we believe privacy should be built into software architecture by default. Unlike conventional online OCR converters that send your files to distant cloud servers, Lanternbrowsetral operates under an uncompromising zero-knowledge, 100% client-side computing architecture.

Section 1 Client-Side Execution Guarantee

All image files, screenshots, scans, and documents loaded into Lanternbrowsetral.com are parsed entirely within your browser's local sandbox memory using WebAssembly. No image binary data, extracted text strings, or associated metadata ever leave your computer or transmit to external hosting servers.

Section 2 Information We Do Not Collect

Because processing occurs client-side, Lanternbrowsetral does not collect, record, or store any of the following:

  • Your uploaded image files or photos.
  • The text content extracted from your documents.
  • Your personal identification, email addresses (unless submitted via our support form), or IP addresses.
  • User document history or character output logs.

Section 3 Support Form Data & Communication

If you choose to submit inquiries through our Support Form, we collect your name, email address, and message content solely for customer support troubleshooting. This communication data is never sold, shared, or utilized for marketing purposes.

Section 4 Browser Local Storage

Lanternbrowsetral uses browser localStorage purely to remember your consent status (such as accepting cookie/storage notices). No tracking tokens, cross-site identifiers, or persistent user profiles are created.

Section 5 Security Architecture & User Rights

Because your document data stays on your local device, you retain 100% control over your files at all times. Closing or refreshing your browser window instantly purges all loaded image data from active browser memory.

Section 6 Contacting Privacy Officers

For questions regarding our high-security local processing model, please reach out to our privacy compliance department at [email protected].
