Although experimenting with reducing JPG quality is ideal, not everyone has time to try different values for quality and compare, for each image. If your images are a very high resolution, you probably can afford to reduce the quality to the lowest setting when you save your JPG files.
I wish I could give you a hard-fast rule to follow, but unfortunately, this is one of those things, that is simply not that simple. In general, higher quality means larger file sizes however, often with JPGs lossy compression you’re not losing as much as quality as you might have feared, but you also may not get the file size down as much as you wanted either. Not just go down, fall drastically, so that’s what we’ll focus on in this post. So, all we need to do is resize the image for your target screen, and you’ll see your file size go down. If your ebook will most likely be read on a phone, there’s no point in cramming a poster size image into the palm of your hand. Many of the extraordinary DLSR photographs and Photoshop® creations are produced for large prints, sometimes even poster size. Along the way, we’ll give you some extra tips, and in the end, you’ll get to see the results: the images and the real data.īefore you get started, you should probably check out The Ebook Author’s Guide To Images.
We’ll also give you ideal dimensions for ebook book covers, ebook app icons, and for the images inside your ebook. We’ll show you how the three affect the image’s file size. There are several attributes that contribute to the size of your images’ files: physical image size, resolution, and file type. Image optimization means reducing the file size without reducing your image’s wow factor (or it’s informative value).
