However, this compression ratio comes at a cost of reduced quality that becomes more evident after zooming in on the image. Lossy compression algorithms always have a superior compression ratio (the ratio of the size of a compressed image to the original image) as compared to lossless compression. data loss in lossy compression is irreversible. This is not the case in lossy compression i.e. In lossless compression, it is possible to reconstruct the original image from the compressed image because there is no information loss during compression. Choosing the correct format and compression is a major factor that determines image size.Ĭompression can be of two types - lossless and lossy. Use GIF format for images that contain animations.Īlmost all forms of data that we see on the internet - text, image, video etc. - are compressed to reduce the size of data and ensure faster transmission. Use PNG format for any image that needs transparency or for images with text & objects with sharp contrast edges like logos. Use JPEG format for all images that contain a natural scene or photograph where variation in colour and intensity is smooth. Understanding these major differences would help us deliver the best possible images to our website and mobile app users. However, these 3 image formats have significant differences amongst themselves thus making each of them suitable for specific use cases. Several statistics reports, including the one from HTTP Archive, indicate that these 3 formats together comprise of more than 95% of all images loaded on websites. In this post, we would only be looking at the three most commonly used image formats in websites and mobile applications - JPEG, PNG and GIF. I bet most of us wouldn’t have come across 90% of the image formats listed on Wikipedia. According to the SEC filing, "The transaction resulted in the payment of approximately $26.4 billion in cash merger consideration.There are hundreds of image formats available each with a specific use case. The acquisition was completed on December 8, 2016. On June 13, 2016, Microsoft announced plans to acquire LinkedIn for $26.2 billion. LinkedIn filed for an initial public offering in January 2011 and traded its first shares on May 19, 2011, under the NYSE symbol "LNKD". Based in the United States, the site is, as of 2013, available in 24 languages, including Arabic, Chinese, English, French, German, Italian, Portuguese, Spanish, Dutch, Swedish, Danish, Romanian, Russian, Turkish, Japanese, Czech, Polish, Korean, Indonesian, Malay, and Tagalog. According to the New York Times, US high school students are now creating LinkedIn profiles to include with their college applications. The site has an Alexa Internet ranking as the 34th most popular website (June 2018). LinkedIn participated in the EU's International Safe Harbor Privacy Principles. The "gated-access approach" (where contact with any professional requires either an existing relationship or an introduction through a contact of theirs) is intended to build trust among the service's members. Members can invite anyone (whether an existing member or not) to become a connection. LinkedIn allows members (both workers and employers) to create profiles and "connections" to each other in an online social network which may represent real-world professional relationships. As of April 2017, LinkedIn had 500 million members in 200 countries, out of which more than 106 million members are active. As of 2015, most of the company's revenue came from selling access to information about its members to recruiters and sales professionals. Founded on December 28, 2002, and launched on May 5, 2003, it is mainly used for professional networking, including employers posting jobs and job seekers posting their CVs. LinkedIn is a business and employment-oriented service that operates via websites and mobile apps.
