Your documents stay yours
“100% private” is a claim every PDF tool makes. Here's exactly how it's true here — in plain language you can verify yourself.

Your file loads into browser memory
The browser reads your PDF directly from disk using the standard File API — the same mechanism any local app uses. At no point is it attached to a network request.
Processing runs on your own device
Merging, splitting, compressing, and editing all happen through JavaScript libraries running in your browser's own engine — no server-side PDF engine involved.
Nothing is ever uploaded
The result is generated locally and handed back to you as a direct download. Your original file, the intermediate data, and the final result never touch our servers.
Want proof, not promises? Open your browser's Developer Tools (F12), click the “Network” tab, and use any tool on this site. You'll see the page's own assets load — but no request ever carrying your PDF's content, because none is ever sent.
