No. Processing runs in this browser. The page does not send the selected file to a Callpdf server.
PDFs that require a password are not supported in this version. Remove protection with the correct password before using the tool.
Large documents may use substantial memory and can take longer. Close other heavy tabs and try a smaller file or fewer pages if the browser stops.
Newly generated files preserve the visible content handled by this tool, but advanced forms, bookmarks, annotations, layers, or scripts may not carry over.
A current desktop version of Chrome, Edge, Firefox, or Safari is recommended. Browser memory limits vary by device.
