My goal is to create a Kindle Cover and upload it following Amazon recommendations.

The Cover Should Be:

MAXIMUM: Width:1563px; Height:2500px; JPEG up to 127KB

MINIMUM: Width:625px; Height:1000px; JPEG up to 127KB

I found a Powerpoint template that helps me to create Kindle covers. However the size of it is: 541px x 864px and 107KB. So, I resized the template to Kindle standards, but now I have a picture that is 1563px x 2500px and 731KB.

Using Photoshop and Save for Web I can turn the quality option to low. The result of it is: 1563px x 2500px and 198KB. It's still too heavy/large for Amazon standards.

How can I reduce the file size further without making the image dimensions smaller?

Many Thanks.

I would recommend you don't use the maximum size allowed, and instead go for something a bit smaller instead.

Depending on how complex your image is, a bigger size will definitely require a loss in quality. Your true limit in this case is the 127Kb. My reasoning is: You should aim for the maximum quality you can get without passing that weight.

So if you want to keep the width/height ration of 1.6, you can go for 1000x1600px and the cover will still look good and have no visible quality loss. In my opinion, a 127Kb and 1563x2500px image is simply very, very difficult to achieve without completely ruining the quality.

Yisela, You are right! My only limit must be the 127Kb and adjust the rest for that. Is there a way to set in advance Photoshop to render the images with the 127Kb that I need? MANY MANY THANKS! –  Ronaldo Aug 25 '13 at 21:24
    
@Ronaldo I'm not aware of any, but maybe you could ask it as a new question as I'm sure there must be 'creative ways' of achieving that :). I would do it by re-sizing and saving for web, trying to keep the JPG quality at around 75-80%. –  Yisela Aug 25 '13 at 21:34

Image > Image Size > then drop the resolution.

There's a read out at the top that tells you the pixel dimension. So basically can change it to an accepted size while choosing the best quality.

Crejus, Many Thanks.I have tried already what you said but without success. –  Ronaldo Aug 25 '13 at 19:11
    
Dropping the resolution (AKA the pixel dimensions) will work, of course, but will drastically reduce the quality as now the pixels all have to be 'stretched'. –  DA01 Aug 25 '13 at 21:15

I don't know how you will use that image but reducing colors can be a solution.

Does the file have to be saved in a specific format? Maybe you experiment saving in different formats seeing how some are lossy and may reduce the file size. Try JPG instead of PNG.
