There are hundreds of in-depth reviews, open source alternatives to proprietary software from large corporations like Google, Microsoft, Apple, Adobe, IBM, Cisco, Oracle, and Autodesk. The software collection forms part of our series of informative articles for Linux enthusiasts. The collection covers all categories of software. Read our complete collection of recommended free and open source software. Multithreaded PNG optimizer, forked from Optipng Utility and a library for lossy compression of PNG images Image compression tool providing lossless, bit-exact storage for any type of photo Perceptual JPEG encoder with excellent compression density at high visual quality Best lossless image compression software full#For each application we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources. Let’s explore the 9 compression tools at hand. All of these tools are released under a freely distributable license. To provide an insight into the quality of software that is available, we have compiled our recommended commnand-line image compression tools. Any compression software which allows you to minimize your outgoings is definitely worthy of investigation. While it’s relatively cheap to store your files on the cloud, especially when you use an infrequent access storage class, your monthly outlay can start to mount up when storing many thousands of photographs. Whether you keep your collection stored locally and/or in the cloud, you’ll probably need to take further steps to prune the size of your photographs. Is your image collection consuming an inordinate amount of space? You’ve probably already identified and removed duplicate images from your collection. Ever since its introduction, we’ve seen improvements to its compression algorithms seeking to reduce file sizes, improve quality, and speed up encoding time. Its best suited for photographs or images with a number of color regions. JPEG is an image file format that’s been around since the early 1990s, and it uses lossy compression. Best lossless image compression software archive#45% of the images seen on sites crawled by HTTP Archive are JPEGs. According to the HTTP Archive, 60% of the data transferred to fetch a web page is images composed of JPEGs, PNGs and GIFs. They are the most popular resource type on the web. Images take up massive amounts of internet bandwidth because they often have large file sizes. Lossy compression techniques are used in all DVDs, Blu-ray discs, and most multimedia available on the internet. The fact that information is lost during compression will often be unnoticeable to most users. Lossy compression is typically used to compress video, audio and images, as well as internet telephony. When the file is uncompressed, not all of the original information will be recovered. Lossy compression is a data encoding method which reduces a file by discarding certain information. Besides reducing transmission bandwidth, compression increases the amount of information that can be stored on a hard disk drive or other storage device. Compressing data can be very useful particularly in the field of communications as it enables devices to transmit or store data in fewer bits. Data compression is the process of storing data in a format that uses less space than the original representation would use.
