Privacy Policy
Last updated: September 2026
Your privacy is not a feature at Online Pdf Tools — it is the foundation of how the platform is built. This policy explains, in plain language, what happens to your data when you use this site.
Your files never leave your device
The most important point first: PDF processing happens entirely inside your browser. When you use tools like Merge, Split, Compress, Convert, or Watermark, your browser reads the file and writes the result locally on your device — the file is never uploaded to any server we control.
This means we simply cannot see the contents of your documents, because they never reach us. Close the tab and the file is gone from memory — nothing is retained on our side.
What we actually collect
Like most websites, our server automatically logs standard technical data: browser type, operating system, the pages you visit, and visit duration. This data is used only to understand aggregate performance and improve the site; it does not identify you personally.
We do not ask you to create an account, we do not ask for your email address, and we do not request any personal information to use the tools.
Cookies and local storage
We use your browser's local storage (localStorage) to remember your preferences — language, theme, and recently used tools. This data stays on your device and can be cleared at any time from your browser settings.
The site may use cookies or similar measurement for statistics and third-party advertising. These tools never see your document contents — because that content never touches the network in the first place.
The one exception: AI tools
Specific features (the AI assistant, summarization, and OCR) rely on AI models that run on a server. When you use only these features, the necessary data (document text or an image of a page) is sent for processing and the result is returned to you.
These requests are not used for model training, and we do not retain them after the request completes. If you prefer to send nothing at all, every other tool keeps working — they all run 100% locally.
Your rights
Because we collect essentially no personal data, there is very little to delete — but you can always clear your browser's local storage to remove every trace of your use of the site.
