There are plenty of image size calculators out in the world. But most leave you with an uncompressed image, or with clunky software to use.
What I’ve got here is an image size calculator that has the option to compress your images online before even downloading them.
Benefits of Online Compressor
Image compression can benefit users by having pictures load faster and webpages use up less space on a Web host. Image compression does not reduce the physical size of an image but instead compresses the data that makes up the image into a smaller size.
Size Reduction
File size reduction remains the single most significant benefit of image compression. Depending on what file type you’re working with, you can continue to compress the image until it’s at your desired size. This means the image takes up less space on the hard drive and retains the same physical size, unless you edit the image’s physical size in an image editor. This file size reduction works wonderfully for the Internet, allowing webmasters to create image-rich sites without using much bandwidth or storage space.
Resizing.app
Best Photo Resizer
One of our favorites is an online image resizer, called Resizing. app. The company has a straightforward website and process to resize images online within seconds. One of the coolest features is the ability to export your newly sized image into a different format.
Resizing. app couldn’t be easier to use. You simply drag and drop your images into the box on the home page. Then you select how you want to resize your image (by width, by height, custom size, by percentage, or by the largest side of the image). You can choose to compress your image for quality assurance and then just pick your new file format (jpg, png, or web). Once you hit the save button, your new image is saved to your computer. Voila’ all done. No frills but also no hassles.
Unfortunately, this online service does not have any additional photo editing capabilities to go along with resizing. But hey! It’s free, and we like free and simple.
If you resize your images and photos regularly, we highly recommend you to add the Resizing extension to your Google Chrome; it is also entirely free.

Image compression is a proven model to gain a meaningful amount of loading speed for a web page.
