I will convert raster into vector or vice versa

Vectorize ( Vector trace ) is to redraw & convert raster file format (resolution dependent format: .jpg, .png, .psd, .bmp, .tga, etc.) into vector file format (resolution free format: .ai, .eps, .pdf, .svg, .cdr, etc.) to make it ready to print to any size without Jagged or Blurred.

Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color value. Unlike a vector image, raster images are resolution dependent.

Vector images are made up of basic geometric shapes such as points, lines and curves. The relationship of the shapes is expressed as a mathematical equation which allows the image to scale up or down in size without losing quality.

The resolution is the image quality of a printer or monitor. With monitors, the resolution is measured by the number of pixels horizontal by pixels vertically as shown in the picture of 800x600 pixels. Printers also have a measure of resolution called DPI (dots per inch).

Resolution - measured in pixels per inch (ppi) or dots per inch (dpi) - is the term used to represent this density. 2 common resolutions are 72 ppi and 300 ppi. 72 dpi is considered “low-res” and 300 dpi is considered the minimum for “high-res.”
