Finding the page you need in a long document.

PDF Preview: limits and things worth knowing

Pages are rendered by your browser, so the file is never uploaded — which matters for the very common case of checking a document you are not sure you should be opening at all.
Thumbnails render progressively, so a long document is usable before every page has drawn.
This is a viewer only; it makes no changes to the file.

Is it private and secure?

Your privacy is built in. PDF Preview does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

We also measured the competition. Our PDF upload audit recorded how many bytes each of 20 online PDF tools actually transmits: 12 of the 13 measurable services uploaded the whole test file, and Filevane transmitted 0.00 MB.
