3. Now you should see your image in the main window. Click on 'Image' in the top menu bar and select 'Scale Image'.4. In the new window that pops up from step 3, enter your desired dimension for width in percentage. By entering the width in percentage, Gimp will automatically calculate the optimal height for you. For web pages, 600 is usually a good width. Click on 'Scale' after entering your new dimensions and voila, your image has been resized. Make sure to save it under a new name so as not to override the original.
How to resize an image on Mac with Gimp
The steps for resizing an image with Gimp on macOS are largely similar to that of windows.
- Open Gimp, click 'Open' under 'File' in the upper lefthand menu bar at the top of the page. Here you can find and select the image you wish to resize.
