Image editing in QuickLook

QuickLook allows a user to quickly look at an image by selecting it and then hitting the spacebar on the keyboard. It works on all the common formats of image files including:

• jpeg/jpg
• tiff
• gif
• bmp
• png
• heic
• jfif
• webpb

as well as about 50 others.

Incidentally it also reads most text formats, PDF files, and most archive files.

Find a graphic file that you would like to edit, select it by clicking on it once only, and then tap on the spacebar.

In the top right of the header if the image you will find the edit icon (red arrow below)

Click on it to get the editor running. The top left of the window will now have the image editing tools:

From left to right, here is what each tool does. Note that the ones with a down arrow will open up a sub menu with more options:

Tool	Description
	Sketch a shape using a single stroke. If your drawing is recognized as a standard shape, it’s replaced by that shape; to use your drawing instead, choose it from the palette that’s shown
	Click a line or a shape, then drag it where you want. To resize the line or shape, use the blue handles. If a shape has green handles, use them to alter the shape
	Type your text, then drag the text box where you want it to be
	Highlight selected text
	Add Signature
	Change the thickness and type of lines used in a shape, and add a shadow
	Change the color of the lines used in a shape
	Change the color that’s used inside a shape
	Change the font or the font style and color
	Rotate the selected object
	Crop. Hide part of an item. Drag the corner handles until just the area you want to keep is shown within the frame’s border. You can also drag the frame to reposition it. When you’re ready, click Crop
	Enter, view, or edit a description of an image. (The tool is highlighted when an image has a description.) Image descriptions can be read by screen readers and are useful for anyone who has difficulty seeing images online. For example, if you’re using VoiceOver, the built-in screen reader on Mac, you can press the VoiceOver command VO-Shift-L to hear a description of the image in the VoiceOver cursor.
