Is Split PDF safe?

Clean risk

Split PDF uploads the opened PDF file to falcon.zonepdf.com when you click its injected Split button.

On PDF pages, Split PDF injects a Split button and first requests a bearer token from zonepdf.com. If you click the button, it reads the current PDF as a blob, sends the file and URL-derived filename to falcon.zonepdf.com, then links you to zonepdf.com to continue splitting.

Where it sends data
