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.

Is this a visual comparison?

No. It is a text and content comparison — lines of text are extracted and matched page by page. It does not compare images or exact pixel positions.

Why does it find nothing in my scanned PDF?

A scan holds no text layer. Run it through OCR PDF first, then compare.

Text/content comparison. Lines of text are extracted from both PDFs and matched page by page — this is not a pixel-level visual comparison, and scanned pages without a text layer cannot be compared.
