One of the best applications on Ubuntu to take Screen shots is Flameshot.

Flameshot offers almost all the essential features that you would ever require on a screenshot tool in Linux.

The app lets take a screenshot of your whole screen or a specific section, annotate it, and then save it locally or upload to Imgur,with the URL automatically copied to your clipboard ready to paste elsewhere.

A powerful open source screenshot and annotation tool for Linux, Flameshot has a varied set of markup tools available, including:

  • Freehand drawing
  • Lines
  • Arrows
  • Boxes
  • Circles
  • Highlighting
  • Blur
  • Text
  • Pin

You can customise the color, size and/or thickness of many of these image annotation tools.

There are also on-screen buttons to:

  • Move screen selection
  • Undo
  • Copy to clipboard
  • Save file
  • Upload to Imgur

A lot of users want to simply upload their screenshots directly to the cloud in order to easily share it with others.

You can do that by syncing your saved files to a cloud storage solution like MEGA and share them later. But, that’s quite a few steps to follow in order to share your screenshot, right?

So, here, Flameshot lets you upload your image directly to Imgur with a single click. All you have to do is share the URL.

Do note that these uploads will not be associated with your Imgur account (if you have one) and will be only accessible to the ones with the link.

The whole point of having a 3rd party screenshot utility is the ability to annotate the pictures.

You can choose to add an arrow mark, highlight a text, blur a section (pixelate the area), add a text, draw something, add a rectangular/circular shaped border, add a counter number, and add a solid color box.

In addition to all the useful features, it also gives you the ability to customize the UI, filename (when you save a screenshot), and some general options as well.

You just head to the tool settings when Flameshot is active. It should look like this:
