Frequently Asked Questions
How can I convert a scanned PDF to a searchable PDF?
Upload your scanned PDF to our OCR PDF tool. Select your document's language and click 'Run OCR'. Our in-browser Tesseract engine scans the document, injects a selectable text layer, and downloads the searchable PDF.
Is my scanned document uploaded to a server?
No! Tesseract OCR operates completely inside your web browser sandbox using WebAssembly. No text elements or document pages are ever transmitted to external servers.
What languages does the OCR tool support?
The OCR engine is configured with English text datasets by default to recognize alphanumeric characters, ensuring fast and accurate layouts parsing.
Does OCR PDF support big file sizes?
Since OCR runs within your browser, processing speed depends on your machine's processor and memory. We recommend splitting large documents into segments for the fastest performance.
