Are my files uploaded to a server?

No. Every file you select is processed entirely inside your browser using your device's own memory. Nothing is uploaded, stored or shared, so customer documents never leave your computer or phone.

Is there any limit, watermark or sign-up?

No. The tool is free, unlimited and needs no account. Output files carry no watermark of any kind.

How accurate is the recognition?

Accuracy depends on the scan. Clear, straight, high-resolution pages read well; blurred, skewed or handwritten pages often do not. Always check the output before relying on it.

Why is the first run slow?

Your browser downloads the recognition language data once, then keeps it cached. Recognition itself runs on your device, so large documents take time.

About this tool

Run text recognition over a scanned PDF in your browser and get either a searchable PDF, where the page image is kept with a text layer behind it, or a plain text file of everything that was recognised.
