The difference between free and paid plans
The main difference between the paid and free plans of Autoclipping.com is the maximum allowed image resolution. In case of the free plan, it is 0.4 megapixels. For paid plans it is 4 megapixels. But what does that mean for the pictures you have cut out the background from? If you want to know more, continue reading!
How many pixels? How many pixels per inch?
What is a pixel? A pixel is a tiny point on your display, it is usually made up of three little microscopic light emitting elements of different colors: one red, on green and one blue. By combining the various intensities of these three colors, all the colors you can see on your display are created. That doesn't actually cover the whole spectrum of colors the human eye can percieve, but it comes close enough in most cases.
How many pixels does your display have? One million at least or in other words at least 1 megapixel. A megapixel is simply a word you can use in place of one million pixels. If you have a regular HD display, it will have roughly 2 megapixels. If you are a graphic designer, do video editing as a professional or if you are a developer, a gamer or a power user who likes to use the latest technology you may have a 4K display. A 4K display has roughly 8 megapixels.
The other thing to consider is how big your display is. There is no point to having a 8 megapixel display 2 inches across, unless you plan to look at it through a lens or a microscope. However when a display is 25 inches across, 8 megapixels looks very nice and 2 megapixels is barely sufficient. The term used to talk about how big a display is in relation to its resolution is pixels per inch or simply PPI
When it comes to PPI the magic number is 300. 300 PPI is used for most high quality print material. Mobile and tablet screens also hover around 300 PPI, many are even higher. So, if you want to fill half of an A4 with a picture of an object you have erased the background from at 300 PPI, you will need a 2 megapixel image. How did we arrive at this number? A sheet of A4 paper is 8.27 by 11.7 inches, half of that is 4.14 by 5.85. At 300 PPI that would make 4.14 x 300 pixels by 5.58 x 300 pixels, which comes to 2179710 pixels or roughly 2 megapixels.
The bottom line
As a result of the PPI of print media and most phones, tablets and displays, you will not be able to use the free plan to delete the background of objects you want to later use in print media or display at any size bigger than a smallish preview image on a tablet or a phone. In most cases, you will need to use the paid version of Autoclipping.comGo back
