Can you imagine a website without a single image? To tell the truth, I can’t. Whatever kind of website you own it goes without saying that your content includes a number of images. Consequently, any website owner should be aware of free online image optimizer tools to ensure smooth website performance and good user experience.
The Impact of Images
Perhaps, nowadays even a kid knows this obvious truism: “A picture is worth a thousand words”. So, it’s not surprising that visual content has become an inevitable part of each and every website.
On the one hand, images really do a great job. They grab the attention of your online audience and help you convey the message clearly. Is it possible to create an online store or personal portfolio without various galleries showcasing your products and services? Of course, not.
On the other hand, images can play a bad joke on you. If you don’t care about their size and quality the images may simply kill the best website idea. It’s quite evident that heavy, not optimized images overload your website with hundreds of unnecessary kilobytes. Thus, the loading speed of your web pages slows down significantly causing worse website performance and poor user experience.
According to the Kissmetrics statistics, 47% of consumers expect a web page to load in 2 seconds or less. Moreover, 40% tend to abandon a website that takes more than 3 seconds to load. Furthermore, one-second delay decreases your customer satisfaction by about 16%. Hence, the website overloaded with not optimized images has almost no future. Does this mean that your website should do without images?
A Simple Way out – Free Online Image Optimizer Tools
Fortunately, the solution to the problem is rather simple and available to anyone. Free online image optimizer tools are the very thing you need to cope successfully with the task. They help you reduce image size and optimize images for the web. The best thing is that if compressed properly your images don’t lose their original quality.
Frankly speaking, the number of free online image optimizer tools is quite large. That’s why to save your time and effort I decided to tell you about my favorite ones in this article. Hope, you’ll find them useful and easy to apply. However, there’s one thing you have to define before using any of these free online image optimizer tools. First and foremost, you should realize what types of images your website needs.
Types of Images for Your Website
Probably, you know that there are three common file types of images optimized for the web. They are JPEG, GIF, and PNG. So, it’s a good thing to find out their peculiarities before saving your image.
JPEG (or .jpg) images are definitely the most widely used file type on the web. They are great for photos and images with a wide range of colors, gradients, and shades. You can compress them considerably without losing the high quality of the original image. Therefore, they are the best bet for showcasing your products and services online.
GIF (.gif) images have a lower quality than JPEGs and are restricted to 256 colors. Consequently, I don’t advise you using them for large product images. However, they will perfectly do for smaller images with few colors, for instance, icons.
PNG (.png) images have two versions – PNG-8 and PNG-24. While working with this image type always bear in mind that PNG-24 file size is three times larger than PNG-8. The main advantage of PNGs is their ability to handle transparency. So, they work well as logos.
Have you already decided what file type you need? Then it’s high time to get acquainted with free online image optimizer tools.
Free Online Image Optimizer Tools
TinyPNG / TinyJPEG
TinyPNG / TinyJPEG is a free online image optimizer I’d like to begin with. Firstly, it allows you to compress and optimize images and photos for both JPEGs and PNGs. This convenient image optimizer uses smart lossy compression techniques to significantly reduce the size of your file. Actually, the difference in the quality of the original image and the reduced one is almost invisible. However, the size of the two files differs greatly – up to 70%. Secondly, TinyPNG / TinyJPEG gives you an opportunity of bulk uploading (up to 20 images 5MB each). However, the registered users can convert images up to 50MB. Thirdly, the optimizer also provides you with Photoshop plugin for Windows and Mac.
Compressor.io is a handy online image compressor that enables you to reduce your image size with no loss in quality. To start with, this image compressor supports 4 file formats: JPEG, PNG, GIF, and SVG. Note, that the file size limit is 10 MB.

You should simply drag and drop your file or select one from your computer and wait for several seconds. Unfortunately, this online image compressor doesn’t allow bulk uploading.
Kraken is one more ultra-fast free online image optimizer that will please you with the quality of the reduced images. Similar to Compressor.io this image optimizer allows you to choose between lossless and lossy compression. Although you are free to upload an unlimited number of images, each image file can’t exceed 1 MB. The distinctive feature of Kraken is that you can select the level of chroma subsampling and the kinds of metadata you’d like to preserve. Moreover, you don’t have to wait till all your images are compressed. You can even close your browser and download the final files later. They are available for download for 12 hours after optimization.
JPEGmini grants you with an opportunity of reducing image size by up to 80%, without compromising quality. In fact, the JPEGmini algorithm fully imitates the perceptual qualities of the human visual system. It perfectly removes all redundancies and doesn’t create any visual artifacts in the process. To start the compression you are to simply upload the image that needs optimization. The second step is to choose a compression level (from 0-99, with the default at 65) and pick the image width. Finally, you click on “Optimize Photo” and that’s it! The only drawback of this free online image optimizer is clearly seen from its name. You can optimize nothing more but JPEGs.
Optimizilla is a smart free online optimizer using the best combination of optimization and lossy compression algorithms. This tool wisely shrinks JPEG and PNG images to the minimum possible size keeping their quality on the high level. Optimizilla makes it possible to upload up to 20 images. Perhaps, the unique feature of this image optimizer lies in the instant preview. It allows you to compare an original image to the compressed one. Moreover, you can click on thumbnails in a carousel to adjust the quality setting (for JPEGs) or color palette (for PNGs). What’s more, you can download ready images individually as well as a zip file. There’s only one thing to remember. Optimizilla deletes all the images you upload after an hour.
Shortpixel is one more amazing free online image compressor. The main distinguishing feature of this tool is that it supports both image files (JPG, PNG, GIF), and PDF files. On the whole, the process of compression doesn’t differ from other image optimizers: download, compress and get an optimized file. However, the number of the files you are free to download is much more – up to 50 images! If you want to compress more than 50 images, you should register (Free) to get a quota of 100 images/month. The maximum file size of each image has to be not more than 10MB.
Resize Photos is a fascinating free online photo tool for resizing and compressing your digital photos. The tool lets you work with the files of 5 following formats: JPG, PNG, GIF, BMP, and PSD. Alongside with compression Resize Photos lets you apply various editing effects to your image such as captions, borders, reflections, shadows, rounded corners, rotation, etc. This tool enables you to choose the image width, quality, and output format via quality settings before you start compression. Keep in mind that a higher quality setting results in larger file sizes. As a rule, the best output quality setting is somewhere between 60-80%.
