Bookmarklets

Bookmarklets are little JavaScript programs stored as bookmarks. They can be used for various purposes.I mainly use them on Android (Kiwi browser). They work on most (if not all) mobile & desktop browsers.

How to "install" :
  • Make a bookmark of any page  
  • Edit the saved bookmark
  • Change the name*
  • Remove the whole URL
  • Paste the JavaScript code in the URL spot
  • Save the (new) bookmark. It's a bookmarklet now!
On desktop the hyperlinks can simply be dragged to the bookmarks bar.


Here are just a few of the bookmarklets I find useful & use frequently:

Most were gathered from the web; some were made by me, some were (stolen and) modified by me lol.



The JavaScript codes of the bookmarklets I listed above in the table are added as hyperlinks. Just long press/right click and copy the link address

*I usually start my bookmark(let)s' names with an x, because I seldom google words or phrases starting with x or visit sites starting with x. This prevents suggestions (from history & auto complete) from interfering. Choose a short yet descriptive name.

How to use :
  • Open the desired page where you want to use the bookmarklet (if not already open)
  • Start typing the name of the desired bookmarklet in the URL bar
  • Click on it, when it shows up in the suggestions
  • Once clicked, the JavaScript will be executed on the page
Obviously there isn't one single way to use them. These are the general steps. There can be additional steps after the last listed step, depending on the bookmarklet's function.


To undo and revert the possible changes caused by the bookmarklet, just reload the page.
