Got Questions?

Frequently Asked Questions

Fact-based answers regarding ai smart ocr pdf capabilities, security, and format support.

How does OCR process scanned documents?

Optical Character Recognition analyzes document pixels and text glyphs, extracts recognized text into an editable report, and embeds a selectable text layer over the scan.

Which languages are supported by FileNova OCR?

FileNova currently supports 11 core languages: English, Spanish, French, German, Italian, Portuguese, Japanese, Chinese (Simplified), Korean, Russian, and Arabic.

How accurate is the OCR text recognition?

Accuracy is calculated dynamically for each page. Recognition quality depends primarily on original scan resolution (150–300 DPI recommended), clear contrast, proper page orientation, and sharp typography.

Does OCR require an internet connection?

The OCR engine runs entirely in your browser. On first use, the browser downloads the required WebAssembly core and language traineddata (~10–25MB), which is then cached locally for subsequent processing.

Are confidential legal, tax, or medical scans private?

Yes. All OCR recognition executes locally in WebAssembly inside your browser. Your document bytes never leave your device and are never transmitted to external cloud servers.

Is the searchable PDF text overlay supported for all scripts?

Extracted plain text is fully available for all 11 languages in the text output box. The embedded invisible text overlay within the downloadable PDF uses standard Latin encoding, making it ideal for Latin-based documents.
