The short version: the PDFs you pick are not sent to a server. Reading the file and writing the new PDF both happen inside your browser.
How files are handled
- The PDF you choose is opened in browser memory only. Its contents, its name and its page count are not transmitted to a server or to any third-party service.
- Originals are not written to localStorage, sessionStorage, IndexedDB or cookies.
- Reloading or closing the tab clears the loaded file and the edits. Only the file you downloaded persists.
- The resulting PDF does not record the original file name.
- Titles and items typed into the printable forms are only turned into a PDF inside the browser; they are not sent or stored. The form pages fetch the Korean font they embed from this site.
Analytics and ads
The site currently includes no analytics or advertising scripts. Loading a page still sends connection information, such as your IP address and requested URL, to the hosting server. See the site privacy notice for details.
If that ever changes, this page is updated first.
Network requests
Opening the page fetches this site’s own HTML, scripts, styles and the preview support files (font data, character-encoding tables) from the same address. While you are editing a file, no network request related to your PDF is made.
No requests to external domains are used. You can confirm this in the Network tab of your browser’s developer tools.
Limits of this statement
Things outside this site’s control — browser extensions, corporate network inspection, operating-system backups — behave on their own terms. For highly sensitive documents, working offline is the safer choice.
