Extracted Text Preview
Executed 100% locally on your browser
When you upload files, they are read as binary arrays in your browser's sandboxed RAM. We use high-performance WebAssembly engines and Client APIs to execute all processing locally. No files are sent to our servers, keeping your documents 100% confidential and secure.
Convert scanned PDFs and photo documents into searchable, copyable, and selectable text. PDFVoid uses a browser-based WebAssembly OCR engine that runs offline in your tab.

Frequently Asked Questions
How does the OCR engine run without a server?
We load a high-performance WebAssembly port of an OCR model (like Tesseract.js) directly into your browser. This model runs on your machine's CPU threads to recognize characters offline.
What languages does the OCR tool support?
Our standard model supports English character recognition, extracting text from scanned pages, invoices, and photos.
Is my scanned document uploaded to any database?
No. The scanned image arrays are read directly in browser memory and parsed on your local CPU. Your confidential documents remain private.
