Privacy Policy

Last updated: June 2026

1. What pdfzen does with your files

All file processing on pdfzen (image-to-PDF conversion, PDF compression) is performed entirely within your web browser using client-side JavaScript libraries. This means:

• Your files are never uploaded to pdfzen's servers or any third-party server
• Your files are never stored, logged, or transmitted over the internet
• Processing happens on your own device — the same way a desktop app would work
• When you close or refresh the page, all file data is gone from memory

2. Information we collect

pdfzen collects minimal anonymous data to understand how the site is used and to improve it:

• Analytics: We may use privacy-respecting analytics (such as page views and general usage patterns). No personally identifiable information is collected through analytics.
• Feedback submissions: If you use the feedback form on any page, your message and optional email address are transmitted to us via Formspree so we can respond. We do not share this with third parties.
• Cookies: pdfzen uses only essential cookies required for the site to function. We do not use advertising cookies or third-party tracking cookies.

3. Google AdSense

pdfzen displays advertisements served by Google AdSense. Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising by visiting Google's Ads Settings.

Google's use of advertising cookies is governed by Google's Privacy Policy, which you can review at policies.google.com/privacy.

4. Third-party services

pdfzen uses the following third-party services:

• Google Fonts — to load the Inter typeface. Google may log font requests.
• Formspree — to receive feedback form submissions. See Formspree's privacy policy.
• pdf-lib — an open-source PDF library that runs locally in your browser. No data is sent to pdf-lib's maintainers.

5. Children's privacy

pdfzen is not directed at children under the age of 13. We do not knowingly collect personal information from children.

6. Changes to this policy

We may update this privacy policy from time to time. When we do, we will update the "last updated" date at the top of this page. Continued use of pdfzen after any changes constitutes acceptance of the updated policy.
