Top 5 Image Compression Software Free Download for PC

Nowadays, people can easily take high-quality photos with a mobile phone, let alone to say digital camera. These photos are of really high definition and the contained details are usually too rich to be necessary for all purposes. For example, a website has to store and process thousands of pictures uploaded by users, then it doesn’t hope each image is as large as 10 MB, in which way the loading speed will be super slow and the cost will be high. Actually, in many cases, we are required to upload or send pictures in a size of less than 100 KB or even 20 KB. With a good image compressor, it is convenient to compress dozens of images into reasonable sizes in a minute, and without significantly decreasing the definition.

In addition to size and definition, which are the core features, many image compression tools also allow users to crop and optimize images. These settings are customizable in some of the best image compressors, while some others will make the whole procedure automatic and ideal. It’s all up to you to choose which tools for different purposes. Some free photo editing software can also do the same thing, but the image compressors below will apply this singular task in bulk and quickly.

Tips: The bad side of the following powerful image compressors is that the image could be over-compressed if it was small already before the compression. Thus, it is necessary to keep the original files. Otherwise, you’re suggested to use RePicvid Free Photo Recovery to get lost images back 100% for free.
