Privacy Policy

Last updated: July 2026

Your files never leave your device

1PDF is built on a simple principle: we never see your documents. All PDF processing — merging, splitting, converting, encrypting and everything else — happens entirely inside your web browser using client-side technology (JavaScript and WebAssembly). Your files are never uploaded to our servers, never stored, and never shared with anyone. When you close the tab, nothing remains.

Optional cloud storage (Pro)

Local-only processing is the default and always will be — nothing is uploaded unless you explicitly ask for it. If you have a Pro subscription, you can optionally choose "Save to cloud" after processing a document. Saved files are stored on Cloudflare R2 (data centers in the EU/US) so you can download them again later. Files from a monthly plan are kept for 30 days and files from a yearly plan for 1 year, then deleted automatically. You can also delete any saved file yourself at any time from your account page.

Data we do not collect

  • We do not collect, store, or process the content of your files.
  • We do not require accounts, email addresses, or any personal information.
  • We do not use tracking cookies for analytics.

Advertising

To keep 1PDF free, this site is supported by advertising. We may use Google AdSense, which uses cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings. Advertising partners never have access to the files you process — that data never leaves your browser.

Server logs

Like most websites, our hosting provider may record standard technical information when you load a page (IP address, browser type, timestamp). These logs are used only for security and operational purposes and are not linked to any files you process.

Changes to this policy

If we update this policy, the revised version will be posted on this page with an updated date. Continued use of the site after changes means you accept the new policy.
