Ultra Zoom on Microsoft Edge
Ultra Zoom works on Microsoft Edge. It is the same build that ships to Chrome, installed from the Chrome Web Store, which Edge supports natively — so there is no separate Edge Add-ons listing to hunt for. The same is true of Brave, Opera, and Vivaldi. This page covers how to install it, and why Edge’s own zoom cannot do the job an image-zoom extension does.
Installing on Edge
- Open the listing in Edge — go to the Ultra Zoom page on the Chrome Web Store using Edge itself, not Chrome.
- Allow other stores — the first time you visit the Chrome Web Store in Edge, a banner appears offering to allow extensions from other stores. Click Allow extensions from other stores. This is a one-time setting.
- Click Get, then Add extension. Ultra Zoom appears in the Edge extensions menu and starts working immediately — there is nothing to configure.
Ultra Zoom uses no Chrome-only APIs, so nothing degrades on Edge. Manifest V3, the extension service worker, the site plugins, and on-device upscaling all behave identically.
Why Edge’s built-in zoom is the wrong tool
Edge has zoom: Ctrl+=, the zoom control in the menu, and pinch-to-zoom on a trackpad. All three scale the rendered page. The image element on screen gets larger; the image data behind it does not change.
That distinction is everything on a modern site. Pages serve responsive image variants — a product grid hands your browser a 400-pixel-wide file even though the merchant uploaded a 3000-pixel one. Zooming the page stretches the 400-pixel file. Hover-to-zoom requests the 3000-pixel file. The long version is on the blog.
Edge’s other image features have the same limitation for a different reason. Web Capture screenshots what is already on screen at the resolution it is drawn, so capturing a thumbnail produces a thumbnail. Collections saves a link and a preview. Neither one goes back to the host for the source file.

Brave, Opera, and Vivaldi
All three install from the Chrome Web Store the same way, and Ultra Zoom behaves identically on each.
- Brave — shields do not interfere. Ultra Zoom requests the source image from the same host the page already loaded the thumbnail from, so nothing new is being contacted. Brave users tend to care that the extension has no analytics endpoint at all; the architecture write-up covers what that means in practice.
- Opera — install the Install Chrome Extensions add-on from Opera’s own store once, then install Ultra Zoom from the Chrome Web Store as normal.
- Vivaldi — installs directly from the Chrome Web Store with no extra step.
On Firefox, Ultra Zoom is a native add-on rather than a Chromium build — see Ultra Zoom vs. Firefox built-in zoom.
