Adjust Image Brightness sly מאת

Adjust Image Brightness lets you brighten or darken any image right on the page you’re viewing—no upload, no download, no new tab.

Open the extension, click an image, and move the slider. Values above 100% brighten; below 100% darken. Everything runs locally in your browser, so your photos never leave your device.

Why install it?
Because sometimes you only need a quick look: Does this product shot need more light? Is the sky too washed out? Will this thumbnail still read if it’s darker? Instead of saving the file, opening an editor, and exporting again, you get an instant on-page preview in seconds.

Ideal for designers, marketers, content reviewers, and anyone who wants a fast brightness check while browsing—lightweight, private, and built for the moment you need it.
