Importance of Bookmarklet

The term “Bookmarklet” is important in the realm of technology as it represents a small, specialized software application that adds extended functionality and convenience to web browsers.

Essentially, a bookmarklet is a bookmark with embedded JavaScript code that executes specific actions or tasks when clicked.

Instead of merely leading a user to a website, bookmarklets can enhance a user’s browsing experience by providing quick access to useful tools, such as webpage translation, content sharing, or text highlighting, all without having to leave the current webpage.

Their compact size, customizable nature, and ease of use make them valuable resources for individuals seeking improved efficiency and personalized browsing experiences.


Bookmarklets serve a vital purpose in enhancing the online browsing experience for users. They are web-browser extensions that act as shortcuts, providing users with quick access to a broad array of features and tools on a web page.

By adding a bookmarklet to one’s browser, individuals save time and effort, since they don’t have to open a new tab or search for a specific function. A variety of tasks can be completed through bookmarklets, such as saving articles to read later, generating citations, translating text, or even modifying a website’s appearance, all with just a click of a button.

One of the major advantages of using bookmarklets is their compatibility with multiple browsers, making them a versatile and resourceful solution for users. Unlike traditional browser extensions, bookmarklets don’t require an installation process, as they are essentially small snippets of JavaScript code that run within the browser itself.

This makes them relatively lightweight, easy to configure, and less susceptible to compatibility issues due to different operating systems or browser updates. Overall, bookmarklets provide an efficient and customizable way for users to tailor their browsing experience according to their personal preferences and needs, resulting in a more enjoyable and productive time spent online.

Examples of Bookmarklet

Pinterest Save Button: The Pinterest Save Button is a popular bookmarklet that allows users to save images and ideas they find on any website to their Pinterest boards. When users come across a great recipe, a beautiful image, or an interesting article, they can click the Save Button in their browser bookmarks to add the content to their Pinterest account. This makes it easier for users to collect and organize their favorite content from across the internet.

Pocket: Pocket is a powerful bookmarklet that helps users save articles, videos, and web pages to view later, even without an internet connection. With the Pocket bookmarklet installed in their browser, users can easily save content to their Pocket account by simply clicking the Pocket icon in their bookmarks bar. The saved content can then be accessed on any device with the Pocket app installed, making it convenient for users to enjoy their content whenever and wherever they choose.

Evernote Web Clipper: Evernote’s Web Clipper bookmarklet is a useful tool that allows users to clip and save content from the web directly to their Evernote account. By clicking the Evernote Web Clipper icon in their bookmarks bar, users can choose between saving an entire web page, a simplified version (without ads and clutter), a screenshot, a selected piece of text, or a bookmark of the page. The clipped content will be synced across all devices connected to the user’s Evernote account, making it easy to access and organize important information.
