Small tools.
A more thoughtful browser.
Modulus Tools is an independent home for focused Chrome extensions and custom browser workflows. Our collection brings together tools for images, playback, links, data, and everyday work.
One tool. One clear purpose.
Preview an image without opening another tab, choose when a video plays, or gather a group of links in one gesture. Each tool has its own feature page, availability status, and support link.
Explore the collectionPrivacy in plain language.
Our extension policies explain what stays on your device, what permissions are used, and when an action contacts another website. Local processing does not mean the websites you visit stop making network requests.
Read individual policiesGuidance that gets specific.
Our guides describe controls in the Modulus Tools versions, with examples and limitations. If a site behaves differently, contact us with the extension name and steps to reproduce the problem.
