Regex Replace is a versatile Chrome extension designed to let users replace content on any website using powerful regular expressions. You can inject HTML, images, CSS, JavaScript, and other features anywhere on a page, customizing your browsing experience fully.

The extension includes advanced options such as applying replacements by domain, URL, keyword, or global regex matching. You can bulk edit rules via a text file, toggle regex flags, activate or deactivate specific replacements, and see applied regexes on the page with the ability to copy matches. Chained regex allows conditional application based on other content matches, supporting complex patterns like negative and positive lookahead. Developed by creators of distraction-free extensions since 2012, Regex Replace is a robust tool for users who want deep customization of web content integration and replacement.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Regex Replace requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

Regex Replace has earned a fairly good reputation and likely can be trusted.
