Support

Before writing to us, these cover the most common questions:

• Documentation — setup, privacy guarantees, supported formats and troubleshooting.
• Tutorials — step-by-step walkthroughs that each end with a saved result.
• Changelog — what shipped recently, in case a fix is already out.

• Tools not loading? Hard-refresh with Ctrl/Cmd + Shift + R — a stale cached build is the usual cause.
• A tool seems stuck on a large file? Processing runs on your device, so very large documents depend on your machine — give it a moment or try a smaller file.
• Something looks broken? Note your browser and version — Zehnax targets current releases of Chrome, Firefox, Edge and Safari.

Still stuck? Email support@zehnax.web.app and include:

• what you were trying to do and where it went wrong;
• your browser and operating system;
• screenshots or the exact error text, if any.

Please do not attach confidential documents — remember, nothing you process in the tools reaches us, and support cannot see your files.

If you believe you have found a security issue, email support@zehnax.web.app with the details instead of publishing them, and we will investigate and coordinate a fix with you.
