Zero Server Upload Guarantee

MergPDFOnline utilizes local browser execution (WebAssembly & client-side JavaScript). When you merge, split, compress, or edit documents on our website, your files never leave your computer or smartphone and are never uploaded to any remote server.

1. Information We Do NOT Collect

We believe in strict data minimization. We do NOT collect, inspect, process, or store:

  • Your PDF files, document contents, text, or embedded imagery.
  • Your passwords entered for document encryption.
  • Your drawn electronic signatures or contact details from signed agreements.

2. Cookies and Third-Party Advertising

To keep this service 100% free and unlimited for all users globally, we may display non-intrusive advertisements (such as Google AdSense). These third-party vendors may use cookies (including the DoubleClick cookie) to serve ads based on your visit to this and other websites.

Users may opt out of personalized advertising by visiting Google Ads Settings (www.aboutads.info).

3. Security

Since your documents remain completely local to your browser environment, they are inherently protected by your device's native operating system sandboxing and HTTPS TLS 1.3 transport security.
