It supports fairly good compression (i.e. small file size compared to the uncompressed original), particularly for line drawings or images with few colors while being\u0026nbsp;lossless compression (i.e. no image information is lost).\u0026nbsp;\u003c/p\u003e\u003cp\u003eBMP and TIFF are usually large files with little if any compression (although many versions of TIFF exist).\u003c/p\u003e\u003cp\u003eJPG offers excellent and aggressive compression but at the expense of variable amounts of loss (thus lossy-compression). The higher the quality number (0-100) the less compression and the less data loss.\u0026nbsp;\u003c/p\u003e","id":1544,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/1544","nextQuestionPath":null,"relatedArticles":[],"alsoUsedIn":[{"id":244,"kind":"Course","title":"Preparing images for publication","link":"https://radiopaedia.org/courses/preparing-images-for-publication"},{"id":608,"kind":"Course","title":"Radiopaedia 2020 - Lectures Only - page 608","link":"https://radiopaedia.org/courses/radiopaedia-2020-exclusive/pages/608"},{"id":608,"kind":"Course","title":"Miscellaneous Lectures - page 608","link":"https://radiopaedia.org/courses/miscellaneous-lectures/pages/608"},{"id":608,"kind":"Course","title":"2020 Virtual Conference Private Use - page 608","link":"https://radiopaedia.org/courses/2020-virtual-conference-private-use/pages/608"}],"stem":"\u003cp\u003eWhich of the following formats allows for fairly good compression while being non-lossy?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/1544"}],"attemptsPercentages":[{"alternativeId":"7711","percentage":11},{"alternativeId":"7709","percentage":27},{"alternativeId":"7710","percentage":55},{"alternativeId":"7708","percentage":8}],"promptToLogin":false,"questionManager":false,"articleId":"image-preparation"}
