Optimizing and managing images for web apps is not an easy thing to do. For that reason, many decide to skip this important step. If you are one of them, you are making a huge mistake. Optimized images improve your overall SEO and engagement, as well as contribute to the technical strength of your app or site.

There are tons of things that you can achieve with image optimization. Starting from decreased page size to faster-loading pages, a bit of effort and the right tools can really turn things around for you.

Below you'll read all about such image optimization tools. But right now, let's start by explaining what this is and why it's important for you.

Understanding Image Optimization: Why is it Important?

There are different ways of optimizing an image. When you need to use it for a web app or website, this is mostly related to resizing the media file you have. You can’t just use a simple program to reduce the file size without losing image quality. If you need to do it, which is highly likely for a web app, you need a quality tool to help you with this.

But, it doesn’t stop there. Image optimization can include compressing file sizes, but it also covers file types, names, thumbnails, and even alt attributes. Simply put, you’d be optimizing the file to make it of the best quality possible.

Reduced image files increase the user experience by loading faster. Research shows that great images can also result in higher conversion rates.

Optimize images for website are also vital for SEO. Google is a fan of fast-loading, high-quality, optimized images. You are boosting your chances of ranking higher in searches if you spend some time fixing those multimedia files.

Now that you know this, it is time to find out which are the best tools for image optimization.

Best Tools for Image Optimization for your Web App

Apps require quality images of smaller sizes. When you try to resize and optimize an image you have, things can go one of two ways. You will make it smaller in both, but unless you know how to truly optimize it, the quality can become disastrous. That sure doesn't help your SEO or look appealing to the audience and users.

That being said, here are the top tools you can use to make this process simpler and faster.

EWWW Image Optimizer

If you're looking for a free image compressor with good features, this is it. Optimizilla will fix your images by using lossy algorithms.
