Avoid Upscaling Your Photo
Be aware of your photo’s maximum size. Making them bigger than the allowed size may potentially blur and pixelate your photo and hurt the quality of your image. Use a larger photo, if possible, to get the most out of it.
Check the Size of Your Photo
To determine the size of your photo, look up the pixel resolution of your JPEG. Divide the resolution by 300 for print, and 150 for signage. For example, 1,200 x 900 = 4 x 3 inches.
