First Impressions 

From the first impressions we got, all the tools are quick enough to get the picture according to the above list. The fastest one was ShortPixel, followed by TinyPNG, and so on. Most tools, like Bulk Resize Photos, Squoosh, and Optimizilla, offer the feature of choosing the quality percentage of the picture you uploaded. Thus, you can select and adjust the settings according to your needs easily. For the sake of the test, we tried to put the settings even in each platform for you. Since all of them are free image compression tools, it was a very beneficial and quick process for us to enhance our SEO endeavors. 

ShortPixel Results  

ShortPixel provided the best image compression compared to the other tools I tried. The free tool from ShortPixel is really just a sales pitch to persuade you to upgrade to their paid product. That will allow you to add more features and remove the file size limitations. If you are trying to upload a lot of pictures at the same time, ShortPixel allows you to download them one by one. That can be time-consuming if you have lots of photographs and have limited time.  

What is great about ShortPixel is that it comes with a WordPress Plugin. Its plugin is better if you have a WordPress website since you can do bulk image compression. It can immediately compress the images on your website if you add them to your media library.  

One additional advantage of the plugin is that you can choose a maximum width or height for photos. So that ShortPixel can automatically resize the images. Hence, clients can’t upload images that are 6000 pixels wide (1920 pixels is more than enough!). 

We cannot say that the webpage interface was our favorite, but we can definitely suggest the WordPress Plugin since it is best for your WordPress websites.  

TinyPNG Results 

Compressing your photos is surprisingly easy with TinyPNG. Simply drag and drop your file onto the website (or up to 20 files at once). After you upload your files, your photographs will begin to be analyzed and compressed right away. Actually, there are no options to select the quality of the picture or the percentage of the size. If you are sending your clients to that site, it is great, but if you want more options for your own, unfortunately, you can only upload and download. You need to download your pictures one by one manually, or you can download them in a zip file, which is great for time management.  

Similar to ShortPixel, TinyPNG also offers a WordPress Plugin for image compression. You can easily and quickly compress your images on your website without dealing with websites and so on. TinyPNG stands out with its simplicity and efficiency since you do not deal with the settings of quality and so on. So, if you are looking for a simple tool without complexity, you can definitely choose  TinyPNG.  

Optimizilla Results 

Optimizilla is similar to TinyPNG regarding interface and the amount of pictures you can upload. You can easily drag and drop your pictures up to 20.  

You can really obtain a higher image compression rate when it is compared to TinyPNG because you have more fine-grain control. However, as you move the slider down, you’ll notice a difference in quality. The best option is Optimizilla if you want more control and don’t mind editing the files. 

Squoosh Results 

Squoosh is the most modern one when it comes to User Interface (UI). You can easily drag and drop pictures there, but, unfortunately, you can only upload them one by one. We couldn’t find a possible way that you can upload lots of images together at the same time.  

Nonetheless, after you upload a file, you have the most options available, including the ability to resize the image, alter the color scheme, choose the sort of compression you wish to use, and adjust the image’s quality. There are also more advanced options that you can adjust so that you can change and adjust the format in line with your needs.  

If you want more control over your image compression and uploading individually does not bother you, you can pick Squoosh for your website image compression.  

Bulk Photo Resize Results 

Even though it was not bad, compared to the other tools, we can say that it was the worst in our list since its job is not image compression but resizing. The ability to quickly resize a large number of photographs similarly is its greatest power, we can say.  

This allows you to shrink all your photographs by a specific percentage or make them all the same width, height, or both. It’s easy to resize all your photographs (regardless of their aspect ratio) to a maximum width or height by selecting the “Longest side” resize option. 

Unlike the other tools we tested, it is clear that Bulk Photo Resize is the fastest among all. Since they do not upload pictures to their servers, you can upload and resize photographs up to 150 in 60 seconds. Once you upload it, you can select its options to resize the photograph and change its format to JPG, PNG, or WEBP.  

If you want a tool to resize your photos easily and bunch photos together, you may prefer Bulk Photo Resize.

Frequently Asked Questions About

Image compression is a process of reducing the file size of an image while attempting to maintain its visual quality. It is vital for websites because smaller image file sizes lead to faster page loading times, improved user experience, and reduced bandwidth consumption. This can result in better search engine rankings and increased user engagement. 

Lossy compression reduces image file sizes by permanently discarding some image data, often resulting in a slight loss of quality. Lossless compression, on the other hand, reduces file sizes without any loss in quality. Lossy compression is typically used for web optimization, while lossless compression is preferred when image quality preservation is critical. 

Many web-based image compression tools, like Squoosh and ShortPixel, offer client-side processing, meaning all compression occurs in your browser, and your images are not uploaded to external servers. This approach ensures privacy and security for sensitive images. 

To choose the right tool, consider factors like the level of customization required, the supported image formats, batch processing capabilities, and the desired balance between image quality and file size. Review the features and limitations of each tool to find the one that aligns with your specific project requirements. 

Some image compression tools, such as ShortPixel, offer image backup functionality, allowing you to revert to the original image if necessary. However, this may not be possible with all tools, so it’s essential to check the capabilities of the specific tool you are using before compression.
