To generate link previews, the Signal app uses a privacy-enhancing proxy—the site you’re previewing never even sees your IP address. Link previews are supported on all sites that include HTTPS encryption.

Start by opening the “Signal” app on your iPhone or Android smartphone.

Next, tap your profile picture, avatar, or username initials found in the app’s top-left corner.

Select the “Privacy” option from the overflow menu.

Finally, toggle on or off the “Generate Link Preview” setting.

You can now navigate back to the Signal app’s home screen and open a conversation. The next time you send a website to someone, it will either add a link preview automatically or only send the URL, depending on if you enabled or disabled the “Generate Link Previews” setting.

Link previews in Signal don’t have to be all or nothing. If you choose to leave the “Generate Link Previews” feature on, you can remove previews before sending individual messages.

As before, begin by launching the “Signal” app on your iPhone or Android smartphone.

Next, select a conversation or start a new individual or group chat by tapping on the pencil icon in the app’s top-right corner.

Tap into the “New Message” text box and paste a URL.

A preview image and text snippet will appear above the link. To remove it, tap on the “X” icon found in the top-right corner of the preview box.

You can now send the link without the preview by tapping on the blue arrow button.

The URL will be sent without a link preview.
