I have reduced an image from 1600 x 1200 to 800 x 600
But I find there is a loss in quality in some of the curves which have now become ragged.

( its a pic of a motorbike)
Is there a way to compensate for this? I have tried `sharpen edges` but that didn`t help.

thanks

Correct. This is the way all pixel-based images work.

A pixel-based image is made up of solid squares of color, much like a tile mosaic. Anything you do that increases or decreases the number of pixels causes the computer to make a new set of pixels, by a process called "interpolation." The appropriate colors for these pixels is determined by a mathematical guess. Increasing or decreasing the number of pixels in an image always results in a loss of image quality; this is inherent to the way pixel-based images work.

You’ll need to let us know your intent for the image before we can assist with how to reduce it the best way possible for your purpose. For web or print at what final dimensions? If for print, what type of printing/printing specs?
