What is changing? <\/p>\n<\/blockquote>\n

Until February 28th, 2021, we used to charge 1 credit for every image size that was optimized by our ShortPixel Adaptive Images<\/a> plugin. For small sites, with low traffic and many images, this could mean a large usage of credits. After March 1st, 2021 we are charging 1 credit for every 5 MB of CDN traffic consumed<\/strong>, which means up to 50 images of 100 KB each.<\/p>\n

However, the previous is only relevant if you have an old monthly plan or one-time credits<\/a>. You can subscribe to our Unlimited plan<\/a> and stop worrying about that!<\/p>\n

\n

When will this change become active? <\/p>\n<\/blockquote>\n

Starting 1st of March 2021<\/strong>.<\/p>\n

\n

Who will be affected? <\/p>\n<\/blockquote>\n

This change only applies to ShortPixel CDN users, e.g. ShortPixel Adaptive Images<\/a> or Autoptimize<\/a>.<\/p>\n

\n

Why this change? <\/p>\n<\/blockquote>\n

We're constantly improving our products and we believe that by starting to charge by traffic instead of credits for ShortPixel's CDN, we'll be able to offer a more fair accounting system<\/strong> that will benefit all our current users. And this for a lower price<\/strong>.\u00a0<\/p>\n

Let's take for example 2 use cases:<\/p>\n

    \n
  1. \n

    A small website with a few webpages and about 100 pictures that is visited monthly by 300 visitors.<\/p>\n

    <\/p>\n

    Up till now our free plan (100 image optimization credits\/month) would not have been enough, as the 300 visitors would have probably generated between 2,000 and 3,000 different image sizes\/month. And this would have exceeded the 100 free credits\/month. <\/p>\n

    <\/p>\n

    With the new accounting system, the 300 visitors will most likely generate less\u00a0than 300 MB of CDN traffic\/month and they won't exceed the free monthly CDN traffic, which is 500 MB. <\/p>\n<\/li>\n

  2. \n

    A medium website with 5000+ images that generate 10,000 visits\/month. Currently, a customer will have to pay around $19.99 per month to be able to serve optimized images with ShortPixel Adaptive Images<\/a>.<\/p>\n

    <\/p>\n

    Starting with 1st of March, a plan of $9.99 will allow 500 GB of CDN traffic, and this, from our tests, translates in about 500,000 visits\/month.\u00a0 <\/p>\n<\/li>\n<\/ol>\n

    This means our customers will have to pay less for more<\/strong>! \ud83d\ude42<\/p>\n

    How much CDN traffic equals a credit? How many visits includes each plan? <\/p>\n<\/blockquote>\n
