Paste Diagnostic

Nothing on this page is sent anywhere. No login. No data leaves your phone.

Use it to find out exactly what Safari gives a web page when you paste a poster.

Step 1 — Copy a poster in WhatsApp

Long-press a poster in WhatsApp, tap Copy, then come back here.

Step 2 — Paste it in this box

Clear the box

Step 3 — Read what Safari delivered

Step 4 — Try clipboard.read() (the button way)

Tap this button after copying a poster. It reads the clipboard directly, the way the Family Hub Paste button does.

Try clipboard.read()

Step 5 — Copy test: does ANY image paste work?

Tap the button below. It puts a test picture (made on this page) on your clipboard. Then paste it into the box in Step 2. If the test picture pastes but the WhatsApp poster does not, the problem is what WhatsApp puts on the clipboard — not the page.
