Large-file-size images are a common sight on the websites of professional photographers and other creatives. Users will appreciate the faster page loads after you’ve compressed these images. Your choice of an appropriate image compression tool will depend on a number of factors, including your operating system and the total number of images you intend to compress. Read on as we define image compression, outline its advantages, and investigate 20 separate image compression tools for maximising your website’s performance.
What exactly is image compression?
To compress an image is to shrink the file size while keeping the quality the same. Compressing a digital photo or graphic reduces the amount of data needed to display the image on a computer screen while maintaining the original image resolution. Contrast this with resizing, which simply adjusts the dimensions of a digital photo, and you’ll see that compressing an image is a completely separate operation. Compressing an image is not the same as converting it, which involves changing the format of the original file.
You can compress images in two main ways:
To compress an image without losing information is called lossless compression. Any image compressed using lossless methods can be decompressed at a later time without suffering any quality loss.
Compressing an image using a lossy method involves making permanent changes to the original file. With lossy compression, the computer only throws away the information that isn’t absolutely necessary.
Professionals can benefit from both lossy and lossless image compression methods. Lossy compression’s main benefit is the reduction in file size achieved without significantly degrading image quality. Alternatively, lossless compression doesn’t reduce file size but keeps the image’s quality intact.
Why is it helpful to compress images?
The primary advantage of image compression is the decreased time required for the image to load on a web page. Site visitors may have a better experience overall if loading times are decreased, as this makes it easier for computers to process the image data. This is especially relevant for photography and design portfolio websites, which often feature many high-resolution images.
The following list of 5 various image compression tools can help your website load faster:
1. JPEG Compressor
JPEG Compressor is an intuitive online application that you can use without having to download any software. Images saved in the JPEG file format can be compressed and resized using this tool. Additionally, you can select the level of compression for each image.
Both JPEG and PNG files can be handled by the free and simple to use image optimization tool known as TinyPNG. For images under 5MB each, users can resize and compress up to 20 images at once. TInyPNG also offers paid plans if you want to upload more pictures or compressed pictures with bigger file sizes. The online web version and a WordPress plug-in are the options available to users of the free version.
Users of Kraken.io can simultaneously optimise up to 20 images and download their resized or compressed images either individually or as a zip file. Additionally, users have the choice to upload their optimised images to a number of well-known cloud hosting services. JPEG, PNG, and GIF file formats can all be converted using this programme.

Customers who purchase this app get access to cutting-edge features like WordPress integration, access to a dedicated cloud just for Kraken.io users, and the ability to track statistics regarding their various image optimizations.
Up to 20 JPEG and PNG image files can be simultaneously optimised using the free web service Optimizilla. With the help of this app, you can see how your compressed or resized images have changed both before and after optimization. Users of Optimizilla can also choose the level of compression they want for each image.
Compressor.io is a free online tool for image optimization.
