Compresses images in a folder of your choice, obtaining a compression rate of around 10-20% to make extra room on your hard disk
Your computer stores all kinds of data, and some take up more storage space than other. Most likely, you also use it to store your photos, which can end up taking a significant amount of disk space. Since we're talking about personal memories, it's surely difficult to decide which pictures can be deleted to free up some space. Evidently, an alternative is to reduce their sizes using a dedicated application such as Loseless Image Compressor.
Although lightweight, Loseless Image Compressor is one of those small yet handy tools that serve a particular purpose and do their job without too much hassle. The application is designed to look for images in a specific folder and its subdirectories, and compress them all to obtain additional storage.
Select the folder to scan and perform batch compression
While not necessarily a drawback for some users, the lack of a traditional user interface might not fancy to others. Loseless Image Compressor runs in the Windows console only, prompting you to browse for the target folder at launch. Once you do so, you can sit back and relax: the application starts searching recursively for all the compatible graphic files and applies its compression algorithm as soon as an image is found.
A list of all the identified pictures that have been compressed is displayed in the console and, when there are no more files to process, the application reveals the time it took to complete the task, as well as information regarding the original and the new size of the images. Additionally, the compression rate is calculated on the spot as a percentage. From our tests, we concluded that the compression rate varies between 10% and 20% on most occasions.
No control over the processed files, their type, or any other parameter
Although Loseless Image Compressor seems to do its job flawlessly, there are a few objections that users might have. Aside from the lack of a standard GUI, the application has no filtering capabilities for the file types to process, the size to consider, and so on. It's not possible to create ignore lists, or see the old and new sizes for individual files. You, as the final user, have no word to say on how your images will be processed.
