Cookies & browser storage

Essential storage

The application may use a secure session cookie and an anti-forgery token to protect same-site requests. These are separate from conversion: your file contents are not written into those cookies.

Saved choices

We store your analytics preference and advertising choice in this browser's local storage. Advertising choices expire after approximately 180 days so that permission can be revisited. Browser settings can remove this storage at any time. Clearing it also removes the remembered choice.

Optional providers

If analytics is configured and you opt in, Google Analytics may set its measurement cookies. Google advertising can use cookies or device information even for non-personalized ads. A certified consent platform may store the permissions it collects where required. Exact provider cookies depend on which configured features are active.

Manage storage

Open Privacy choices in the footer to reject analytics or ads. You can also clear cookies and local storage through browser settings. Rejecting optional features does not prevent using the tools. No converted file or QR payload is saved to local storage by these tools.

Read the privacy policy for how page requests and aggregate usage counts are handled.
