Browser Bookmarklet Hub
Supercharge your browser without installing heavy extensions. Bookmarklets are lightweight, single-click JavaScript tools that live in your bookmarks bar. They consume zero background RAM, cannot be blocked by admin policies, and run universally across Chrome, Safari, Edge, and Firefox.
How to Install: Just Drag and Drop!
Make sure your bookmarks bar is visible (Ctrl + Shift + B on Windows/Linux or Cmd + Shift + B on Mac). Click and drag any blue button below directly onto your bookmarks bar. When visiting any site, click the bookmark to execute it instantly!

Frequently Asked Questions
What is a bookmarklet and how does it work?
A bookmarklet is a regular browser bookmark where the URL starts with javascript: instead of https://. When you click it, your browser executes the enclosed JavaScript directly on the webpage you are currently viewing. It can inspect DOM elements, modify styles, extract links, or trigger instant utilities.
Why use bookmarklets instead of Chrome extensions?
Chrome extensions run background service workers continuously, consuming RAM and draining your laptop battery. Many corporate and school devices also block extension stores. Bookmarklets consume 0 MB of background memory, require no permissions, and cannot be disabled by Chrome extension administration policies.
How do I install bookmarklets on iPhone/iPad (Safari) or Android Chrome?
On mobile devices where drag-and-drop is unavailable: Bookmark any random webpage, edit the newly created bookmark, rename it to the tool's name, and replace the URL field by pasting the copied javascript:... code. To run it, simply type the bookmark's name in Safari's or Chrome's address bar and tap the bookmark suggestion!
Are NexaTools bookmarklets safe and private?
Yes. Every bookmarklet in this library is 100% open-source, runs completely client-side in your browser, and contains zero trackers, analytics, or external data leaks. You can click View Source on any card to inspect the exact JavaScript code before dragging it.
Why does a bookmarklet fail on certain banking or security sites?
Websites with strict Content Security Policies (CSP) may block inline JavaScript or external script injection (such as loading external mobile devtools). Bookmarklets that only manipulate native DOM properties (like Unlock Right-Click, Edit Page, or Auto-Scroll) work on virtually all sites.
