Privacy Policy
Last updated: October 14, 2026
The Short Version
We do not want your documents, we cannot see them, and we never save them. Everything you compress on Compress PDF Online stays inside your web browser.
1. Your Files and Documents
When you select or drop a PDF into Compress PDF Online, the file is read and processed entirely by your browser using local client-side scripts. No files are transmitted to our servers or any third-party storage. Once you close or refresh the tab, the working copy in your browser memory disappears.
2. Google AdSense and Cookies
To keep this website completely free to use, we display ads served by Google AdSense.
Google uses cookies (such as the DoubleClick cookie) to serve ads based on your prior visits to this site or other websites across the web. These cookies allow Google and its partners to show relevant ads without accessing your personal documents.
You can turn off personalized advertising at any time by visiting Google Ad Settings.
3. Website Analytics
Like almost every website, our hosting server logs basic non-personal information when you load a page (such as your browser type, operating system, and the date/time of your visit). This helps us keep the site fast and fix technical bugs. None of this data is ever tied to your files.
4. Questions?
If you want to know more about how our in-browser scripts work or have questions about this policy, send us a note through our contact form.
