I have a logo PSD, created in Photoshop (not in AI, not vector) with multiple layers. It is 3000px x 2244px at 300ppi. When I try to resize it to 175 x 57 at 72ppi (or even 300ppi) to put on a website, it pixelates really badly. I do this all the time with other hi-res PSDs but can't figure out what is so different about this file that it would do this.
Any idea what adjustments I need to make to layers, or how I can do this without losing so much quality?
