Long-pressing a thumbnail inside the YouTube app does nothing, which is why this is such a common search. The way around it is to copy the video link from the Share sheet and paste it into a browser tab. On Android the saved image lands in Downloads and appears in Gallery shortly after. On iPhone, Safari asks you to confirm the download and the file goes to the Files app rather than Photos, so you save it across to your camera roll from there.
When to use this
Use for: creators checking a rival thumbnail while away from a desktop, saving reference art to a phone moodboard, grabbing a still to drop into a WhatsApp or Instagram story, and anyone who only has a phone to hand.
Frequently Asked Questions
Where does the image go on iPhone?
Safari saves it into the Files app, not Photos. Open Files, find it under Downloads, then use the share button and Save Image to put it in your camera roll.
Do I need to install an app?
No. This runs in your phone browser. In YouTube tap Share, then Copy link, and paste that link here.
