Privacy in one sentence: PDFZero runs 100% in your browser. Your PDF files and their contents are never uploaded to our servers — there is no server that receives them.
1. Who we are
PDFZero ("we", "us", "our") provides free, in-browser PDF tools at pdfzero.com. This policy explains what data is and isn't handled when you use the site.
2. Your files never leave your device
Every tool — compress, merge, split, OCR, sign, redact and the rest — runs locally using WebAssembly and Web Workers inside your browser. We do not upload, store, copy, read, or transmit your documents. When you close the tab, the file is gone from memory.
3. Information we do not collect
- The contents of your PDFs or any files you open.
- Account information — there are no accounts and no sign-up.
- Names, addresses, or payment details (we don't take payments for tools).
4. Limited technical data
Like most websites, our hosting provider may automatically log standard technical information (such as anonymised IP address, browser type, and pages visited) for security and to keep the service running. We may also use privacy-respecting, aggregate analytics to understand which tools are popular. This data is never tied to your file contents.
5. Third-party services
- Translation: If you choose a language other than English, the page's interface text (not your files) is sent to Google's public translation endpoint to be translated. Your documents are never included.
- AI tools (Chat with PDF): If you use an optional AI feature, only the text you choose to send is transmitted to the AI provider to generate a response. This is always opt-in and clearly indicated.
- Contact form: Our contact page uses Google Forms. Anything you type there is handled by Google under their privacy policy.
6. Cookies & local storage
We use your browser's local storage to remember preferences such as your theme (dark/light) and chosen language. These stay on your device and are not used for tracking or advertising.
7. Children's privacy
PDFZero is a general-purpose utility and is not directed at children under 13. We do not knowingly collect personal information from children.
8. Changes to this policy
We may update this policy from time to time. The "last updated" date above reflects the latest revision.
