Taking a screenshot on an iPhone takes one button press, but the exact buttons depend on your model. Here is the quick reference, plus the fastest way to share the result as a link.
iPhone with Face ID (no Home button)
Press the Side button and the Volume Up button at the same time, then release. The screenshot flashes and saves to Photos.
iPhone with a Home button
Press the Home button and the Side (or Top) button together, then release.
Share it as a link
- Open sshot.online in Safari.
- Tap the upload box and choose your screenshot from Photos.
- Copy the share link and paste it into any chat, email, or ticket.
A link avoids the compression that messaging apps apply and opens on any device. If you are sharing a long web address too, the URL shortener keeps it tidy. Free and no account.
