The 4 best online tools for image compression

Which online tools for image compression are particularly recommendable, I would like to show you in today’s article. As always, I have tried to find the right tool for every user.

Not everyone wants to immerse themselves deeply in image optimization, most probably just want to quickly shrink their images without spending too much time on it or having to deal with the topic.

In the following you will find four online tools for image compression, which are sometimes quite simple and sometimes a bit more detailed.

Image compression is important

When it comes to images on the Internet, it’s always a matter of optimizing as cleverly as possible. Because no matter how much you work on your website to improve loading times, the images often remain one of the biggest factors and slow down the whole site. Not to mention the fact that nobody wants to load more content on their smartphone than is absolutely necessary.

There are several ways to optimize images. For example, you can reduce their size, reduce their quality, remove unnecessary metadata, and much more to make the image files shrink in size in a few simple steps. Then they can be quickly downloaded and displayed in the browser.

The 4 best online tools for image compression

Squoosh

A quite fresh tool for image compression and one of my absolute favorites is Sqoosh. The whole thing was created as a Progressive Web App (PWA), so it also works offline without any known problems or bugs.

The special thing about Sqoosh, if you like, is that the online tool MozJPEG uses a very current and for me almost the best codec when it comes to image optimization. For PNG, the well-known OptiPNG is used, which can also deliver the best results.

Depending on how much you then reduce the quality, the file size of your image will also shrink to a very large extent. Especially the quality control can be used to its fullest, because the result is directly visible in the browser. So it is no problem to go to the limit or to increase the quality a little bit in case of bad results.

TinyPNG

First of all: TinyPNG also optimizes JPG files fully automatically. For me, this is the biggest advantage of the online tool. No settings, no agony of choice, just upload the corresponding image, have it optimized and download the result again. To the normal extent, the whole thing is completely free of charge.

TinyPNG delivers very good results, but I don’t have to deal with the way of compression. The online tool does that for me. Preferably for PNG files. Because even if TinyPNG works with JPG files, the compression there is often not extensive enough for me, which leads to the file getting smaller, but not small enough for my taste.

The latter is also due to the fact that TinyPNG is not supposed to cause a noticeable loss of quality. In my opinion, this is often not a problem with JPGs if the file loses half of its size. In the end, everybody has to decide for himself if he can optimize it largely lossless via TinyPNG or if he can do without some quality and choose another online tool for image optimization.

Compressor

Compressor.io is also very easy to use. The online tool optimizes images, either completely lossless or lossy. When uploading, the user simply chooses a short one, depending on what is desired, and the image compression can begin.

Also the Compressor has the advantage of not providing any options or extensive adjustment possibilities. This may annoy professionals like me who love detail, but it’s ideal for occasional users who don’t want to deal with settings, quality levels or the like.

Works in this case with JPG and PNG files and with an upload limit of 10 megabytes. So it should be sufficient for all images and graphics you want to display on your website. And if not, your pictures are much too big anyway.

Imagify

My fourth and last recommendation, after all the list should not be endlessly long, is Imagify. Many people probably know this from WordPress, because it comes from the developers of WP Rocket and is also available as a plugin.

But the tool can also be used online and is very easy to use. It also tries to be as simple as possible and so there is only the normal, the aggressive and the ultra mode to optimize images accordingly. In each case with little or much loss of quality.

The handling is easy and simple, the compression okay, but not the best I’ve ever seen. However, it always depends very much on the respective motif. Depending on the presentation, optimizations simply have different effects. Since there is no control, the Ultra mode was almost always too violent for me and the picture was ruined accordingly. The other two work perfectly, though.

Imagify is simple and does its job, but it lacks a slider to choose how much compression to compress. In Ultra mode, for example, some images are optimized too much so that they become unusable, whereas Aggressive mode would allow even more. Imagify is therefore best suited for lossless compression.

Compression is mandatory

There are other online tools that can compress images, but they often use similar or identical codecs, with hardly any difference in their settings. That’s why I didn’t just list all online tools here, but a selection of those that have impressed me the most over the last years.

Whoever works with the different tools for a longer time will notice that one works better than the other. Faster perhaps or more effectively in the everyday life, by a simple Upload or conditioned by the own Workflow.

In the end it is not important which tool you use, but that you use one at all. They all optimize images and no matter how much another online tool can get out more, the main focus remains on compressing the images at all. That’s exactly what many people forget or shy away from.

Especially in WordPress, image optimization is very simple. There are suitable plugins that provide compression directly during upload and thus require neither an intermediate step nor extensive control.

At the end let us simply state that the image compression of graphics and images is mandatory. Even if only a few kilobytes are saved, this is calculated on the amount of images, a whole lot of data that does not have to be transferred. This in turn means better loading times and satisfied users.
