How to downsize without losing quality

[fbech]

Hello, I been editing some photos, save them in PSD, the weight is like 5 mg to 8 mg, size like 4320 x2432 or similar. I wan to use this pictures for a web site portfolio and would to keep the same look I got in photoshop with grain effects etc. How can I downsize this whithout affecting quality? I have try to change image size in cs6 or tansform the image , but the quality goes down very clearly. Is there any other way, software etc?


Best regards

I am afraid you will always loose some quality when you shrink so the picture as the file size. One crazy idea - what about saving print screen of the picture in Photoshop, it should downsize it, since monitor resolution is smaller, but could give you what you see.
