Bookmarklet Editor

This editor lets you easily create and edit bookmarklets. You can convert an existing bookmarklet into readable code, or convert readable code into a bookmarklet.

Bookmarklets are similar to browser extensions. I prefer bookmarklets to browser extensions for multiple reasons:

They work on all devices. Desktop, iOS and Android.
They only have access to the page you invoke them on.
It is easy to read, understand and change the code as it is just a single file.
I can organize them just like my other bookmarks.
Sharing a bookmark is as easy as copy/pasting a line of text.

How to use Bookmarklets

Write some code into the textarea.
Click the "To Bookmark" button.
Copy the code into an existing bookmark.
Now, when you click on your bookmark, the code gets executed.

Examples

Here are some examples. When you click on one, the code will be loaded into the textarea.

Ruler - Shows a horizontal line that you can move around with the mouse
Useful to see how elements on a page are aligned.
Increase Font size - Increases the font size of all elements on the screen by 25%
Reader mode often changes the layout of the page too much. And zooming into a page does not wrap the text at the border. For example on Forums, it often makes it hard to read threads. This bookmarklet works nicely on Hacker News, Reddit, Wikipedia and many other sites.
Unsticky - Hides all sticky elements on the current page
