This format, also known as JPEG, is one of the most popular image file formats used in digital photography and web graphics. The term comes from the '<strong>Joint Photographic Experts Group'<\/strong>, the international group of experts who developed the standard. <\/p>\n\n\n\n<nav class=\"wp-block-rank-math-toc-block\" id=\"rank-math-toc\"><h2>Table of Contents<\/h2><div><ul><li><a href=\"#introduction\">Introduction<\/a><\/li><li><a href=\"#specifics-of-the-jpg-format\">Specifics of the JPG format<\/a><\/li><li><a href=\"#jpg-compression\">JPG Compression<\/a><\/li><li><a href=\"#jpg-in-practice\">JPG in Practice<\/a><\/li><li><a href=\"#jpg-vs-other-graphic-formats\">JPG vs. Other Graphic Formats<\/a><\/li><li><a href=\"#modern-alternatives-to-jpg\">Modern Alternatives to JPG<\/a><\/li><\/ul><\/div><\/nav>\n\n\n\n\n<p>The abbreviation 'JPEG' is a reference to a compression method that was designed to reduce the size of image files while maintaining acceptable image quality. <\/p>\n\n\n\n<p>There is a common confusion of terms, where 'JPEG' is a compression standard and 'JPG' is a file name extension used on systems that do not accept more than three letters in extensions (e.g. older operating systems). However, in practice the two terms are used interchangeably and refer to the same image format.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"900\" height=\"598\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-8.webp\" alt=\"jpg - jpg co to znaczy\" class=\"wp-image-6391324\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-8.webp 900w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-8-300x199.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-8-768x510.webp 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\">What is JPG?<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-group dowiedz-sie-wiecej is-layout-constrained wp-block-group-is-layout-constrained\">\n<p><strong>See more<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:18px\"><a href=\"https:\/\/marszalstudio.pl\/en\/removing-background-online\/\" data-type=\"post\" data-id=\"6391724\">6 Best AI Apps for Removing Background OnlineFrom Photos<\/a><\/li>\n\n\n\n<li style=\"font-size:18px\"><a href=\"https:\/\/marszalstudio.pl\/en\/what-is-iso-in-photography\/\" data-type=\"post\" data-id=\"6390488\">ISO in Photography - What Is Noise and How To Remove It<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/marszalstudio.pl\/en\/time-blocking\/\" data-type=\"post\" data-id=\"6404228\">What Is Time Blocking and How Can It Help You?<\/a><\/li>\n<\/ul>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">History and origin<\/h3>\n\n\n\n<p>The history of the JPG format dates back to the late 1980s, when a team of experts from various fields came together to create an image compression standard that would allow for more efficient storage and transmission of digital photographs. The JPEG standard was officially published in 1992 and quickly gained popularity, becoming the global standard for digital photography and graphics.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>The JPEG standard was officially published in 1992.<\/p><\/blockquote><\/figure>\n\n\n\n<p>A key feature that contributed to the proliferation of the JPG format was its ability to <strong>compress images in a lossy manner<\/strong>, meaning that part of the image information is permanently removed to reduce its size. Although lossy compression can lead to quality degradation, in practice JPG allows the right balance to be found between file size and retained image quality, making it ideal for the web, digital photography and printing.<\/p>\n\n\n<style>.elementor-6389332

Graphics<\/h3>\n\n\n\n<p>The format is widely used in many areas of digital imaging, mainly because of its flexibility and ability to reduce file size while maintaining satisfactory image quality. Here are some of the main applications:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Digital photography is the most common use of the JPG format. Most digital cameras and mobile phones use the JPG format as their default photo storage format. This allows photographers to store a large number of images on memory cards and makes it easy to quickly share images on social media or via email.<\/li>\n\n\n\n<li>Web graphics, where due to its compression properties, the format is often the format of choice for creating graphics to be published online, such as banners, images in articles or blog graphics. By using compression, web pages load faster, which improves the overall performance and accessibility of websites.<\/li>\n\n\n\n<li>Printing where, although lossless formats are often preferred for printing purposes, this format is used for photographic printing and some forms of digital publishing, especially when disk space or file size limits are restricted.<\/li>\n\n\n\n<li>Archiving <a href=\"\/en\/\">professional photographs<\/a> where lossless formats are also preferable, many people use JPG to archive their photographs because of the trade-off between quality and file size, saving space on hard drives and servers.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"900\" height=\"900\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-6.webp\" alt=\"What Is JPG?

The process begins by converting the colour space from RGB to YCbCr, which separates the brightness (luminance) information from the colour (chrominance) information. The image is then divided into blocks, typically 8x8 pixels, and a discrete cosine transform (DCT) is performed for each block, allowing the separation of high and low frequency components of the image.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"900\" height=\"600\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-2.webp\" alt=\",\" class=\"wp-image-6391346\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-2.webp 900w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-2-300x200.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-2-768x512.webp 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\">What is JPG?<\/figcaption><\/figure>\n\n\n\n<p>In the next stage, quantisation takes place, a process in which the high-frequency components, which are less noticeable to the human eye, are reduced more than the low-frequency ones. Completing this complex process, finally, the data is encoded using entropy coding, leading to the final, compressed form of the file. The process can be adjusted by setting the quality level, allowing you to decide how much compression you want and how much quality loss may occur.<\/p>\n\n\n\n<p>Quite a complex theory. Now let's get down to specifics. Below are the images in JPG format. One before more compression in JPG format and 100% quality, and the other already much more compressed at 5% quality level. The difference seems to be clearly discernible, but the 5% photo still retains a relatively decent quality.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/100-procent-jakosci-2-1024x683.jpg\" alt=\",\" class=\"wp-image-6391299\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/100-procent-jakosci-2-1024x683.jpg 1024w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/100-procent-jakosci-2-300x200.jpg 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/100-procent-jakosci-2-768x512.jpg 768w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/100-procent-jakosci-2.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">compression at 100%<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/5-procent-jakosci-2-1024x683.jpg\" alt=\",\" class=\"wp-image-6391302\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/5-procent-jakosci-2-1024x683.jpg 1024w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/5-procent-jakosci-2-300x200.jpg 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/5-procent-jakosci-2-768x512.jpg 768w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/5-procent-jakosci-2.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">compression at 5%<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Pros and Cons of JPG Compression<\/h3>\n\n\n\n<p><strong>Pros:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The reduction in file size is the main advantage of JPG compression, saving disk space and allowing images to be transferred faster over the internet.<\/li>\n\n\n\n<li>Basically 100% compatibility of the format by all graphics programs and web browsers.<\/li>\n\n\n\n<li>Adjustment of the compression level, balancing quality and file size.<\/li>\n<\/ol>\n\n\n\n<p><strong>Cons:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>JPG compression is lossy, meaning that once information is removed it cannot be recovered, which can lead to quality degradation, especially when saving the same image repeatedly.<\/li>\n\n\n\n<li>With heavy compression, undesirable visual effects such as blocking, blurring or a 'halo' effect around contrasting edges can occur.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"600\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-3.webp\" alt=\",\" class=\"wp-image-6391334\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-3.webp 900w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-3-300x200.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-3-768x512.webp 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Differences Between Lossy and Lossless Compression<\/h3>\n\n\n\n<p>The main difference between lossy compression (as in JPG) and lossless compression (as in TIFF) is that lossy compression reduces the file size at the expense of permanently losing some of the image information, which can affect the quality of the image. Lossless compression, on the other hand, reduces the file size without losing any information, allowing the original image to be fully restored after decompression.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>For professional applications, lossless compression is preferred.<\/p><\/blockquote><\/figure>\n\n\n\n<p>The choice between lossy and lossless compression depends on the user's needs and the application of the image. For images published on the internet or for personal use, lossy compression is usually sufficient. On the other hand, for professional applications such as high quality printing, photo archiving or precision computer graphics, lossless compression is preferred.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"jpg-in-practice\">JPG in Practice<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How To Create and Edit JPG Format<\/h3>\n\n\n\n<p>Creating and editing JPG files is a straightforward process. To create a JPG file, you can start by saving an image in this format from any graphics program or directly from your camera or phone. Here are a few steps to follow:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Most digital cameras offer a choice of image saving formats, including JPG. It is important to pay attention to the image quality and size settings, as these affect the final file size and quality.<\/li>\n\n\n\n<li>Once the image has been transferred to your computer, you can use any graphic editor for further processing. When saving or exporting the file, select the JPG format and decide on the compression level, which is usually referred to as 'quality'. A lower value means a smaller file size, but also a lower image quality.<\/li>\n\n\n\n<li>Edit images as required - you can adjust brightness, contrast, colour saturation or perform more advanced tasks such as <a href=\"https:\/\/marszalstudio.pl\/en\/photo-retouching\/\">retouching<\/a> or colour correction.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Tools and Programmes Supporting the JPG Format<\/h3>\n\n\n\n<p>Various tools can be used to create and edit JPG files, from professional graphics software to simple online applications. Here are some examples:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Adobe Photoshop<\/strong> - this professional image editing tool offers extensive JPG editing capabilities, including advanced colour correction, layers, masks, filters, etc.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.gimp.org\/\" data-type=\"link\" data-id=\"https:\/\/www.gimp.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">GIMP<\/a><\/strong> - a free alternative to Photoshop, offering many editing features and support for the JPG format.<\/li>\n\n\n\n<li><strong>Paint.NET<\/strong> - a simpler but effective image editing programme, ideal for beginners.<\/li>\n\n\n\n<li><strong>Canva<\/strong> - a web-based application that enables the rapid creation of graphics, including JPG format, using ready-made templates and simple tools.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"600\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-4.webp\" alt=\",\" class=\"wp-image-6391340\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-4.webp 900w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-4-300x200.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2024\/03\/jpg-co-to-znaczy-4-768x512.webp 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Advice for Photographers and Graphic Designers<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Optimise for use.<\/strong> Before saving an image as a jpg, it is worth considering where and how it will be used.
