Privacy Policy

We do not collect, upload, transmit, or store the files you process using our tools — not the file contents, not a copy, not even temporarily on a server. Every conversion, compression, or edit runs entirely inside your own browser, on your own device.

When you drop or select a file in a tool, it is read directly into your browser's memory and processed there using client-side code. At no point does that file leave your device or reach any server we operate. We have no access to it, we do not log its name or contents, and nothing about it is retained after you close or navigate away from the tab.

We do not require an account, a signup, or any personal information to use the Service. We do not knowingly collect names, email addresses, or file contents through the tools themselves.

We may use privacy-focused analytics (such as Plausible or a similar cookie-free service) to understand aggregate traffic — for example, how many people visit a page — without tracking individual users across sites, fingerprinting devices, or building advertising profiles. Any such analytics does not have access to the files you process.

Fonts are self-hosted and bundled at build time rather than loaded from a third-party font service, so viewing a page does not, by itself, send a request to an external font provider.

No tool on this site sends your content to an external AI service. The AI tools run their models on your own device — either a model your browser already provides, or a model file downloaded to your device and run locally. Downloading a model is a request for a public file, the same kind of request as loading a script; nothing you typed, dropped, or opened is included in it, and no text or file you process is transmitted anywhere.

If that ever changes for a specific tool, the change will be stated on that tool's own page before you use it, and this section will be updated to say so.

The Service is not directed at children, and we do not knowingly collect personal information from anyone. Because the Service does not collect file contents or require an account, it is not designed to capture personal information from any user, including children.

Because your files are processed locally and never transmitted to us, there is no server-side copy of your file for us to secure, lose, or expose — the strongest protection we can offer is not having your data in the first place.

We may update this Privacy Policy from time to time. Changes take effect once posted on this page with an updated "Last updated" date. Continued use of the Service after a change is posted constitutes acceptance of the revised policy.
