- Follow the prompt in the test panel and watch the readings update live.
- Press Reset to start over with a clean slate.
About the Clipboard Test
The Clipboard Test writes a test phrase to your clipboard so you can confirm copy and paste is working in this browser. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Diagnosing a site where the copy button does nothing.
- Checking clipboard permissions in a locked-down browser.
Frequently asked questions
Why does it need a button?
Browsers only allow clipboard writes in response to a real user gesture, to stop pages hijacking what you have copied. That restriction is why every copy button on the web needs a click.
Does the Clipboard Test cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the page.
Is the Clipboard Test safe to use with private information?
No. The Clipboard Test runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What do people use the Clipboard Test for most?
In practice it gets used for three things: diagnosing a site where the copy button does nothing. Checking clipboard permissions in a locked-down browser. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Why does the test start on its own?
No installation, no extension and no driver. The Clipboard Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
