how to resize an image without losing quality?

[backtothefuture]

HI

I had a logo designed for my site for which the designer forwarded my jpgs, gif, TIFF and PSD files

I basically need to resize the Jpeg file to 75% using (PSP) but when I save it, those blocky grains keep appearing

How can I resize the image without loss of quality?

cheers!

Does the blockiness appear immediately after the resize or after you save the image? If it's the former then try a different resize method as suggested, if it's the latter then it's likely that the JPEG quality factor is set too low when you're doing the save / save as.

its the latter

ok will check Jpeg quality cheers
