This tool relies on the browser's Clipboard API to read an image straight from what you copied. Support for that API varies more than you'd expect between browsers and operating systems — here's exactly what works where.
Windows and Linux
Chrome, Edge, and Brave all support pasting images fully — press Ctrl+V and it works immediately. Firefox supports it too, though on older versions you may see a permission prompt appear slightly differently.
macOS
Chrome, Edge, and Firefox work the same as on Windows. Safari added clipboard image support in macOS 14 (Sonoma) — if you're on an older macOS version, Safari may not let the page read pasted images even though Cmd+C/Cmd+V otherwise works normally.
ChromeOS
Full support out of the box in the Chrome browser — no extra permissions or setup steps beyond the normal one-time clipboard prompt.
Mobile (iOS and Android)
This is the weak spot. Mobile browsers restrict clipboard API access much more heavily than desktop browsers, for both iOS Safari/Chrome and Android Chrome. Pasting an image from the system clipboard into a web page frequently doesn't work at all, or requires an extra tap-to-confirm step that varies by browser version. If you're doing this regularly, desktop is the reliable option.
Remote desktop sessions (RDP, VNC, browser-based VMs)
Clipboard sync between a remote session and your local browser is handled by the remote desktop software, not by this tool. If image paste isn't working inside an RDP or VNC session, check that the remote software's clipboard sharing is actually enabled — it's a common setting that's off by default in several remote desktop clients.
Quick self-check
If nothing happens when you paste, first confirm you actually copied an image and not a file path or HTML snippet — copying an image from some sources (certain PDF viewers, some Office apps) puts non-image data on the clipboard instead. Our troubleshooting guide covers this and the other common paste failures in more detail.
