Blogger, unlike WordPress, does not have server-side image compression. This means that when you upload your 2 MB image you should expect it to be 2 MB when you add it to your post. Therefore, the only solution to this problem is to compress it before uploading the image. The issue here is that it can be a slow process and there are a number of tools that you can choose from.

While there are many tools it truly comes down to this simple fact. You don’t need to pay for anything and you should avoid desktop applications. If you aren’t particularly savvy you might find desktop image compression complicated and it’s a waste of system resources. Therefore the quick and easy solution is for you to upload the images to various online image compressors and I am going to give you the ones that I prefer to use.

Here are some important notes.

There are two types of compression lossy and lossless. The difference being one affects the image quality while the other is strictly for removing EXIF and other data that is on the images.

Blogger does compress JPEG’s on upload that being said it’s not enough, and PNG’s and other formats are not being compressed.

Certain image types have certain use cases you shouldn’t worry about the image type but for deeper optimization avoid using PNG as they don’t compress as well but use PNG’s if you need or have too.

Website’s To Compress Images

TinyPNG is probably one of the most used online image compression websites and its important to note that it compresses more than just PNG’s it has also added support for JPEG’s this image will get you to pass Page Speed Insight’s testing but there are many cases where it will fall short particularly with photography websites and this is because it doesn’t compress JPEG’s as well and it does very little lossy compression. Therefore you might find yourself needing something a little stronger.

Optimizilla while looking simple is actually extremely powerful you simply need to upload your image (or images) and you will be shown the compressed version and the non compressed version side by side. You can then move the slider on the right hand side to control the compression level. Try sliding it lower in order to reduce the image size even father. The problem with Optimizilla is that it requires some basic knowledge and you will notice image quality loss if you go too low. Try moving it slowly watching the image quality degrade (try decreasing it by 5-10% per test).

Windows Program To Compress Images

While there is less than 0 reason to use a desktop application to do this job, there is a solid program that I have used in the past in order to bulk compress several thousand images. That being said unless you have a specific need for a desktop application it is recommended to use one of the above web services.

Caesium is the best image compression software that can make image compression very easy when you are bulk compressing images. If you have a weeks worth of posts planned out or are a photographer then this tool makes it easy to both compress (lossy and lossless) and resize the images so they are fit for you website. While there is a little bit of a learning curve you can install it on any of your Windows Machines, including Windows 10.
