How do I increase the (dpi) resolution of my pixel graphic and reduce the file size below 10 MB?
Increase resolution (dpi)
Increase resolution
Increasing the resolution of a pixel graphic simply by setting the dpi higher does not achieve the desired results. If the dpi is increased, the height and width of the image must be decreased in proportion to the dpi value. Otherwise, the image will only be enlarged and will appear pixellated.
Change colour channel
Most graphics software programmes are able to retain the image proportions and recalculate them if one of the values for height , width or dpi is changed. This option must be activated (see screen shot "Increase resolution").
Reducing file size
In order to reduce the file size to the desired 10 MB, try to decrease the amount of pixels in the image options. Make sure that the dpi value stays the same while you are doing this.
Another possibility is to create an 8-bit colour channel from a 16 or 32-bit colour channel. This will decrease the file size considerably (see graphic "Change colour channel").
