Picsvg is a free online converter that can convert an image to a SVG file. You can upload an image file (jpg,gif,png) up to 4 Mb, then you can select effects to enhance the SVG image result. While resolution represents the amount of pixels per a given unit of space, the pixel dimension is the total amount of pixels in the image. It could also mean the actual height and width of the pixel, such as 0.26 × 0.26 mm on the monitor and 0.08 × 0.08 mm on the iPhone 4 screen, for example. Here we consider the former meaning. Divide this number again by 1,024 to get the file size in kilobytes (KB). In our example, 2,457,600 / 1,024 = 2,400 KB. Convert this number into megabytes (MB) by dividing the number by 1024. In our example, 2,400 / 1,024 = 2.34 MB. Please refer to this chart to determine the minimum image size you need to produce quality prints. NOTE: If your photo doesn't meet these minimum image-size requirements, you'll see an orange triangle next to one or more print sizes in your cart.
