When we make your digital product ecover for you, we compress it so that it loads faster on your website. Compression saves you in bandwidth and makes your pages load faster.
Here is an example of an ebook cover :
You will find this cover on out “Choose a Cover” page.
This is product HB02 (which means it is Hardback Book #2)
In this example, the dimensions of this picture is 350 x 384.
We have compressed it, using 70% quality and the file size 39K.
Here is the same image, with the same dimensions, but uncompressed:
Even though the image looks the same, and the dimensions are still 350×384 the file size on this image is 113K. This is almost three times the file size!
290% larger to be precise.
That might not seem like much of a difference at first, but consider this:
If someone using using standard dialup internet were to visit your page, it would take 22 seconds to load the uncompressed image. 22 Seconds. That’s a long time.
Granted, most people are no longer on dialup, but you do want to sell your product to as many people as you can right?
Now consider this:
Say your page gets 1,000 visitors a day. Each time someone visits your website, they have to load the page from your server onto their computer, which means your server has to transmit the ecover graphic for each visitor.
The compressed image uses 1.1 gigs of bandwidth per month.
The uncompressed image uses 3.3 gigs of bandwidth per month.
You save money on bandwidth and you take load off your server speeding it up for all the other tasks it must do as well as increasing the speed of the site for your customer, which means a better chance of making a good first impression and thereby a higher conversion into sales.
This numbers become even more important when you use an image of a larger size.
Using the same ebook cover for an example, here is what happens if we increase the file size to 1024 x 1124.
Uncompressed file size = 447K

As you can see, when you have an image with larger dimensions the compression becomes even more important. A larger graphic van even get away with more compression than a smaller image as you can see in the example above.
Normally we would never use a 48% quality on a jpg image, but with the 1024 x 1124 image we linked to above, you can see that even at 48% quality, the image still looks very high quality and text is crisp and sharp around the edges.
Too much compression does lead to lower image quality.
See This Image for example.
You’ll never need to worry about compressing your graphics from us, we always compress them at the optimum level, which gives you the highest quality appearance while making the file size the smallest possible.
