Fix an editor that's slow or laggy

If the Kittl editor feels slow or laggy, this article walks you through checking whether it's your browser, your device, or the project itself, and how to fix each one.

If the Kittl editor is slow or laggy, like clicks take a moment to register, elements drag with a delay, or zooming and typing feel jerky, your browser or device is having trouble keeping up with the design in real time. This is usually caused by a large or complex project, a browser issue, or limited device memory. Most cases improve with the steps below.

Troubleshooting steps

1. Check whether it's one project or all of them

Before troubleshooting your browser or device, it helps to know whether the slowdown is tied to a specific file or something broader.

  1. Create a new blank design and try typing, moving an element, or zooming. A blank design has no heavy content, so this is the clearest way to tell whether the lag comes from your browser or device rather than the original project.

  2. For extra confidence, you can also open a different existing project and try the same actions.

If the blank design lags too, it's more likely a browser or device issue. Continue with the steps below.

If the blank design runs smoothly and only your original project lags, the design is likely large or complex. Head to Fix a project that's slow or laggy for steps on simplifying it.

2. Wait a moment between actions

If the editor feels laggy right after moving multiple elements, zooming in and out, applying an effect, or editing text or images, it may still be catching up with your last action.

Wait a few seconds between actions instead of clicking repeatedly, then check if it feels more responsive. When dragging elements or zooming, move at a slower pace and pause briefly between steps instead of one long continuous motion. This gives the editor a moment to render each change before the next one arrives.

3. Refresh the page

Start with a hard refresh to clear any temporary slowdowns.

Then reopen your project.

4. Open the project in Incognito mode

Incognito mode disables cached data and most browser extensions, so it's a quick way to check whether your browser is the cause.

  1. Open a new Incognito window in Chrome (Cmd + Shift + N on Mac, Ctrl + Shift + N on Windows).

  2. Go to kittl.com and sign in.

  3. Open your project.

If performance improves here, the lag is likely caused by cached browser data or an extension. Continue to step five to narrow it down.

5. Disable extensions and turn off your VPN

Ad blockers, script blockers, privacy or security extensions, and VPNs or proxies can all slow down the editor, even ones that came pre-installed or are already running in the background.

  1. Open your browser settings and go to Extensions.

  2. Disable all extensions temporarily.

  3. Turn off your VPN or proxy, if you're using one.

  4. Refresh the page and open your project again.

Once the editor feels faster, re-enable your extensions one by one and turn your VPN back on separately, to find out which one was causing the issue.

6. Close other apps and browser tabs

If your device is running low on memory, the editor can slow down or start to lag.

  1. Close unused browser tabs.

  2. Close other applications, especially video calls, streaming, or other design tools.

  3. Refresh the page and reopen your project.

7. Update your browser or try another device

The Kittl editor works best on an up-to-date version of Chrome. Make sure your browser and operating system are current, then try:

Still slow or laggy?
