Add an invisible text layer over scanned page images while preserving the source page appearance.

Run OCR on a scanned PDF, PNG, or JPEG source from the same local workflow.

The recognition model runs in the browser after required model assets are available; document bytes are not silently uploaded.

Original pixels remain visible while recognized text supports search, selection, and downstream extraction.

Frequently asked questions

How do I make a scanned PDF searchable?

Select the scanned PDF, choose the OCR language and settings, then create a new PDF with an invisible recognized-text layer.

Does OCR replace the original page image?

No. The original page pixels remain visible and the recognized text is added as a separate invisible layer.

Is OCR accuracy guaranteed?

No. Accuracy depends on language, resolution, contrast, handwriting, and scan quality. Review important extracted text before relying on it.
