These changes can be made in Adobe Photoshop:
- Open your logo in Adobe Photoshop and go to Image > Image size.
- In the box that appears, make sure “Resample Image” and “Constrain Proportions” is checked.
- Set the Width and Height as needed for your logo shape.
- Then, change the resolution to 72 pixels/inch.
- At the very top of the box you’ll notice the size of you file. It should be under 200K.
