Privacy Policy
Last updated: July 11, 2026
This Privacy Policy explains how ZiroPDF ("we", "us", or "our") handles information when you use our website at ziropdf.com (the "Service"). We designed ZiroPDF with privacy as its core principle, and this policy describes exactly what happens to your data.
1. Your files never leave your device
All PDF and image processing on ZiroPDF happens locally inside your web browser using JavaScript. When you use any of our tools:
- Your files are never uploaded to our servers or any third-party server.
- We have no access to the contents, names, or metadata of your documents.
- We do not store, log, scan, or back up your files in any way.
- When you close the browser tab, all traces of your files are removed from memory.
2. Information we collect
Because processing is local, the information we collect is minimal:
- Usage analytics. Like most websites, we may collect anonymous, aggregated statistics such as which pages are visited, browser type, device type, approximate geographic region (country level), and referral source. This data cannot be used to identify you personally.
- Language preference. Your chosen interface language is stored in your browser's local storage on your own device. It is never transmitted to us.
- Contact information. If you contact us voluntarily, we receive the information you choose to share (such as your email address) and use it only to respond to you.
3. Advertising and cookies
ZiroPDF is free to use and is supported by advertising. We use Google AdSense to display ads. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this and other websites:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings.
- Alternatively, you can opt out of some third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.
Users in the European Economic Area (EEA), the United Kingdom, and Switzerland may be shown a consent message before personalized ads are served, in accordance with applicable law.
4. Legal bases for processing (EEA/UK users)
Where the GDPR or UK GDPR applies, we rely on the following legal bases: (a) legitimate interests, for operating and improving the Service and measuring anonymous usage; and (b) consent, for personalized advertising cookies where required.
5. Your rights
Depending on your location, you may have rights regarding personal data, including the right to access, correct, delete, or object to processing of your data. Because ZiroPDF processes files locally and collects almost no personal data, most of these rights are satisfied by design. For any request, contact us via the contact page.
6. Children's privacy
ZiroPDF is a general-audience service and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, please contact us and we will delete it.
7. Data security
The strongest security measure we offer is architectural: your documents are never transmitted, so they cannot be intercepted, breached, or leaked from our side. The website is served over HTTPS to protect the integrity of the pages and scripts you receive.
8. Third-party links
Our website may contain links to external sites. We are not responsible for the privacy practices of other websites and encourage you to read their privacy policies.
9. Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the Service after changes constitutes acceptance of the revised policy.
