There are two honest answers, and which one you need depends on how far you want to go. Chrome can change the picture and the shortcuts on its own page in about thirty seconds. Replacing the page with something else entirely needs an extension: a clock, a countdown, your task list. Below is both, plus how to undo either one.
Less than most people expect. The built-in options cover the background image, the shortcut tiles, and a colour theme. The layout itself is fixed: search box in the middle, tiles underneath, and no way to add anything that’s not a shortcut.
You can’t set the new tab page to a specific website. This surprises people, because Chrome does have a homepage setting and it does accept a URL, but the homepage is the button next to the address bar, not the new tab. They are separate, and only one of them takes a URL.
You also can’t add anything to the page. No clock, no notes, no calendar, no to-do list. The built-in page has one layout and it isn’t adjustable. That’s the point at which everything else on this page starts.
Chrome lets an extension take over the new tab entirely. Install one and your next new tab is whatever that extension draws instead. There are a lot of them, they vary enormously, and they fall into roughly four groups:
| Kind | What you get | Suits you if |
|---|---|---|
| Photo and focus pages | A full-screen photograph, a greeting, often a single task for the day | You want the page calmer than it is now, not busier |
| Minimal pages | A clock, a search box, very little else | You find the default page distracting |
| Launchers and speed dials | A grid of site icons you arrange | You open the same twenty sites and want them one click away |
| Dashboards | Widgets you place yourself, clocks, lists, countdowns, notes, weather | You want the page to carry information, not just links |

The new tab page is valuable to the people who make extensions for it, and a minority take advantage of that. Two things are worth checking, and they take under a minute:

Whatever you install, undoing it is the same three steps, and nothing about your bookmarks or history is affected:
If a new tab page appeared that you didn’t install, remove it the same way and then check Settings → Search engine — that’s the setting the less honest ones change while you’re looking at the pretty wallpaper.
All four are built on the same engine as Chrome and install Chrome extensions, so everything above applies with small differences in wording. Edge may ask you to allow extensions from other stores the first time. Opera needs its Install Chrome Extensions add-on before the Chrome Web Store works. Brave and Vivaldi install them directly, with no extra step.
Firefox is the exception: it has its own add-on store, and a Chrome extension can’t be installed into it. Many new tab extensions publish a Firefox build separately.
This is our extension, so treat the rest of this section accordingly.
New Tab Studio is in the fourth group above, the dashboard kind. You get a blank page and a catalogue of widgets to put on it: countdowns, clocks, task lists, notes, weather, habit trackers. They are dragged into place rather than dropped into a grid, which is the main thing that separates it from the others.
It doesn’t change your search engine. There’s even a search widget setting that deliberately hands queries to whatever engine you’ve already chosen. Your layout is stored in your browser rather than uploaded, and no account is needed to use it.
It’s the wrong choice if you want the page simpler than the default rather than richer. A free-form canvas takes a few minutes to arrange, and if what you actually want is a photo and a clock, something minimal will make you happier with less effort. That’s a real answer to “which one should I use”, and it’s not always ours.
Free, no account, and removable in three clicks if it’s not for you.
Add New Tab Studio to ChromeNot with a Chrome setting. The homepage setting takes a URL; the new tab doesn’t. An extension can do it, several exist for exactly this, but Chrome on its own can’t.
A well-built one, no. The page renders locally. What costs time is a page that loads a remote service on every tab. An embedded dashboard, a news feed, a heavy background fetched fresh each time.
No. An extension draws a different page; it doesn’t touch your profile. Removing it puts the original page back exactly as it was.
Something installed an extension, usually bundled with other software. Open chrome://extensions, remove anything you don’t recognise, then check your default search engine in settings.
Chrome profiles are the general answer, each profile keeps its own extensions and settings. Some dashboard extensions also offer several pages within one, which is lighter than switching profiles.
