How to Crop a Picture Using Paintbrush on a Mac – For Mac OS X, Paintbrush is a free image editing program. Users who seek a basic photo or picture editing tool might consider this easier, lighter alternative to Microsoft Paint on Windows platforms. Cropping is one of the most frequent uses for a photo editor; it is straightforward but not immediately apparent due to Paintbrush’s unconventional user interface.
Step 1: To open the program, click the Paintbrush icon in your Dock.
Step 2: Following “File,” select “Open.” Go to the picture you wish to crop. Click “Open” after clicking the image.
Step 3: Then select “Canvas Size” under “Image.” Choose between cropping based on pixels or percentages using the drop-down boxes. Give the width and height a value. Press “OK.”
Step 4: Select “Save as” from the “File” menu. After deciding on a name, location, and format, click “Save.”
