Is Online PDF Editor (pdf2go.com) safe?

Low risk

Online PDF Editor (pdf2go.com) uploads Gmail attachment content to pdf2go.com cloud servers when a user clicks the in-Gmail compression button.

When a user clicks the 'Compress PDF' button the extension injects into Gmail, it downloads the attachment with the user's Google credentials, base64-encodes the file, and POSTs it to satcore.pdf2go.com. In addition, the extension patches Gmail's XMLHttpRequest prototype to capture full email metadata — including subjects, sender and recipient addresses, and body HTML — for every email viewed, storing it in local caches even though the stated purpose only requires attachment URLs.

Same operator - 4 listings

Published under a different store account, but sharing the registered address, contact or declared legal entity this one gave the store.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed PDF2Go contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • satcore.pdf2go.com

    PDF2Go sends data to satcore.pdf2go.com. No other extension we have analysed sends data here.
