Are my files uploaded to a server?
Files and text are processed in this browser tab, without server uploads or analytics. Language and theme preferences are saved on this device. Closing the tab releases the working files. On the first visit, the site uses the hosting provider’s approximate IP country when available, then your browser language. A language cookie remembers your choice for one year. You can change it at any time.
Will this change my original file?
No. The tool creates a separate result for you to review and download. Keep the original until you have checked the exported content.
