Any solution? On photoshop it has a really good quality, i saved it as jpg max resolution but when i put it on the website it gets so ugly.
Width: 3000 ; Height: 1000 ; Resolution : 3000 Pixels ; RGB Color ; 8 bit ; Pixel aspect ratio : square pixels
I can see that your site's HTML is auto generated by WIX. The 3000 X 1000 Px logo that you uploaded is actually being converted into a 600X200 Px image. A confirmation of this can be obtained by Right Clicking the image, Saving it and checking the saved image.
I would suggest you upload your image in 600X200 resolution, so it is rendered as it is.
