It uses the <code>.gif<\/code> extension and lossless LZW compression on the data represented in the file.<\/p>\n<p><strong>Each frame supports a palette of up to 256 colours<\/strong>, making the format suitable for simple graphics, icons and short animations but less effective for photographs and complex gradients. It also supports basic transparency and does not include sound.<\/p>\n\n<h2>GIF format characteristics<\/h2>\n<p>A GIF can contain several frames and specify how long each one remains visible. <strong>The animation can loop continuously or stop after a defined number of repetitions<\/strong>, although continuously looping GIFs are common on the web.<\/p>\n<p>Its principal characteristics include:<\/p>\n<ul>\n<li><strong>Lossless compression:<\/strong> LZW preserves the stored palette values, although reducing a full-colour source to 256 colours can introduce visible banding or dithering.<\/li>\n<li><strong>Frame-based animation:<\/strong> The file orders images and display times to produce movement.<\/li>\n<li><strong>Basic transparency:<\/strong> One palette colour can be marked as transparent, without the partial opacity levels available in other formats.<\/li>\n<li><strong>Broad compatibility:<\/strong> Browsers, messaging applications and many platforms can display GIFs without an additional player.<\/li>\n<\/ul>\n<h2>Uses of GIFs<\/h2>\n<p><strong>GIFs are used to communicate short movements or reactions without starting a video player.<\/strong> They are common in conversations, social posts and online communities, where they may express an emotion, illustrate a response or repeat a short scene.<\/p>\n<p>They are also used in tutorials, interface demonstrations, loading indicators, banners and emails. <strong>A <a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/meme\">meme<\/a> may circulate as a GIF, still image or video<\/strong>; the concept depends on the shared message rather than the file format. A <a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/cinemagraph\">cinemagraph<\/a> combines an apparently still scene with localised movement and can be distributed as a GIF or another animated format.<\/p>\n<p>In marketing, motion can draw attention to a product, feature or call to action. <strong>The content should remain understandable beyond the animation<\/strong> and should not hide essential information, use disruptive flashing or add unnecessary page weight.<\/p>\n<h2>Creating and editing a GIF<\/h2>\n<p>An animated GIF is created by arranging images or extracting frames from a video. <strong>Video can be the source material, but the resulting GIF stores image frames<\/strong>, not a video or audio track. Graphics editors, converters and services such as Giphy or Tenor can adjust cropping, dimensions, duration, speed and repetition.<\/p>\n<p>Export settings include the palette, dithering, frame count and final dimensions. <strong>Reducing the dimensions, removing redundant frames and limiting the duration can control file size.<\/strong> Alternative text should describe the relevant information, and an equivalent text explanation is useful when an animation is necessary to understand an instruction.<\/p>\n<h2>GIF compared with other formats<\/h2>\n<p><strong>The appropriate choice depends on the content, required quality and download size.<\/strong> The main differences are:<\/p>\n<ul>\n<li><strong>GIF:<\/strong> Suitable for brief graphics and animations with a limited palette, basic transparency and no sound.<\/li>\n<li><strong><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/jpg\">JPG<\/a>:<\/strong> Designed for still photographs and many colours; it uses lossy compression and supports neither animation nor transparency.<\/li>\n<li><strong>PNG:<\/strong> Preserves still images with more colours and alpha transparency; APNG extends the format to support animation.<\/li>\n<li><strong>Animated WebP and AVIF:<\/strong> Provide more colours, transparency and generally better compression for web animation.<\/li>\n<li><strong>MP4 or WebM video:<\/strong> Usually more efficient for long, large or complex sequences and can provide controls and sound.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/web.dev\/articles\/replace-gifs-with-videos\" target=\"_blank\" rel=\"noopener\">web.dev recommends considering video for heavy GIF animations<\/a>, because video encoding can substantially reduce data transfer. <strong>GIF remains useful when the animation is short, simple and compatible with its publishing context.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Definition: A GIF (Graphics Interchange Format) is a raster image format that can store a still image or a sequence of frames played as an animation.
