Colorize Image

Colorize Image is a browser extension distributed through the Chrome Web Store by the team behind livepolls.app. Instead of juggling desktop software, you install the extension, hand it a grayscale or sepia image, and the underlying AI model predicts plausible skin, sky, fabric, and foliage tones to produce a full-color result. The workflow is deliberately minimal — upload, wait a few seconds, download — so the tool suits casual users who simply want an heirloom portrait restored rather than professional retouchers chasing pixel-level control.

The listing reports roughly 2,000 active users, a 4.2-star average from 13 ratings, and a v1.7 release refreshed in November 2025, with interface text available in dozens of languages including English, Chinese, Japanese, Korean, Spanish, German, and French. Being an extension rather than a web app means there is nothing to sign up for before you try it, and it works alongside whatever else you already use in the browser.

Privacy is handled in a straightforward way: the developer states that uploaded data is transient rather than sold to third parties, and the privacy policy indicates uploaded images are deleted on a daily cycle. That said, as with any cloud-based colorizer, you should avoid uploading sensitive identity documents or private material you would not want processed by a third-party service.
