Frequently asked questions
What does the privacy scan look for?
It checks for hidden metadata, interactive form fields, annotations, embedded scripts, and attached files — the kinds of data that can travel inside a PDF without being visible on the page.
Is my PDF uploaded to scan it?
No. The scan runs entirely in your browser, so your document is never uploaded and never leaves your device.
Does it work offline?
Yes — once the page has loaded, you can scan a PDF with your internet disconnected.
Do I need an account?
No. Anonymous users get up to 5 operations per day; a free account gives unlimited basic operations.
