NullClipper

Snip it. Share it.
Nobody in between.

NullClipper grabs a region or a short GIF and puts it on your clipboard. Want to send it instead? One switch turns it into an encrypted link — the key never leaves your device.

NullClipper's capture overlay over a web page: the page dimmed, a Snip/GIF toolbar at the top, and a selected rectangle with a 768 × 236 size badge

Two ways to clip

Same snip, same GIF limits, same encryption. Pick the one that fits where you work.

Chrome · Opera · Edge

Browser extension

Captures the tab you're looking at — nothing else. It never injects code into the page you're on.

  • Current tab only, by design
  • Alt+Shift+X or the toolbar icon
  • Live on the Chrome Web Store and Opera add-ons

Windows 10 · Windows 11

Windows app

A tray app for the whole desktop: any monitor, any window, any shape — freeform included.

  • Region, freeform, window, or full screen
  • Multi-monitor, frozen while you drag
  • One-click installer or a portable zip

Three seconds, start to paste

  1. 1

    Press the hotkey

    Ctrl+Shift+X on Windows, Alt+Shift+X in the browser — both rebindable. The screen freezes so nothing moves while you aim.

  2. 2

    Drag a region

    Everything else dims. Pick Snip for a still image or GIF for up to 8 seconds of motion. Esc cancels.

  3. 3

    Paste it — or share a link

    The PNG or GIF lands on your clipboard. Turn on NullImage and you get an encrypted share link instead.

Optional · NullImage

Share a link the server can't read

With NullImage uploads on, each capture is encrypted on your device with AES-256-GCM before it's sent. The key is generated locally and travels only in the link's #fragment — the part browsers never send to a server.

  • Expires after 1 hour, 1 day, 3 days, or 7 days
  • Burn after the first view, if you want
  • Optional password on top
  • If an upload fails, the image is copied locally instead
About NullImage →

What gets copied

https://nullimage.org/a7Kq2xP9#k=Qm3vT8…Zp4w

Sent to the server

The image id, and the encrypted bytes. Ciphertext only.

Never leaves the link

The decryption key, after the #. Browsers don't transmit it.

Scheme ni1-aes-gcm-256 — identical in the Windows app, the extension, and nullimage.org itself.

No account, ever

Nothing to sign up for — not for the app, not for the extension, not for NullImage.

Nothing phones home

No analytics, no ads, no crash telemetry. Settings stay on your device.

Free and open source

MIT licensed. Every line of both the Windows app and the extension is on GitHub.
