Learn how local processing, session ownership and temporary job storage work, and understand their practical limits.
How is the local conversion service protected?
The default server listens on loopback and checks its own host, origin and session token. Downloads are restricted to the job’s session. These measures do not make native file parsers a complete hostile-file sandbox or provide malware scanning, encrypted temporary storage or secure disk erasure.
Common questions
Do files leave my computer?
In the installed local app, the browser sends selected files to its local server at 127.0.0.1 on the same computer. No external conversion API is used. The optional browser processing modes run supported operations inside the browser instead.
Can I convert files without internet access?
After installing the app, required engines and local runtime assets, conversions can run offline. Initial setup and dependency downloads need internet access. A public guide page alone does not install or run the local conversion engines.
How long can I download completed results?
Temporary local job copies normally expire after about 30 minutes of inactivity. Downloading a result refreshes its lifetime. Clearing jobs or restarting the server can remove working copies earlier. A download you have already saved is independent of that temporary storage.
