Free programmes to sharpen enlarged photos?

Question

I am looking for a free programme to sharpen up photos that have been enlarged or zoomed in. All I want it to reduce the photos becoming so pixalated, so any input at all would be greatly appreciated. Thanks!

Answer 1

Basically programs that sharpen photos also degrade them, it generates ringing effect that looks quite ugly. However there's a new enlargement technique that uses a novel technology that allows to enlarge pictures without making them blurry. Your can try it at this website (just follow the Try it Now link on the left), it's free ;)

Answer 2

Sharpening will not get rid of pixellation it will actually make it worse, you need a bigger file size (more Mb).

Gimp has sharpening tools, you can down load it for free here.
