If you’ve ever tried to save an image off the Internet and instead gotten the “save as a webpage” option, you may have seen an SVG. Great for: printing high-quality photos, scanning high-quality images, anything where size isn’t an issue. Also, no one argues about the pronunciation. You may not have run into a TIFF personally, but if you’re into photography or work much with print media, you may recognize them as the large, but high-quality, format often favored by publishers. Tagged Image File Format (TIFF) – Lossless Raster Great for: simple graphics, animations, icons. Pixels can also be made transparent, but must be either on or off, not in-between. GIFs only support 256 colors, which makes them a poor choice for high-quality photos, but their compression is excellent, so it can downsize simple images without a huge quality hit. The debate over whether to pronounce it as “ gif” or “ jif” is fairly heated, but if you want to make both sides angry, try pronouncing it as “jeff.” The predecessor to PNG, the GIF format is now most famous for enabling the short video loops that you can’t stop watching on social media. Graphical Interchange Format (GIF) – Lossless Raster Great for: web graphics, high-quality photos where size isn’t an issue, transparency. These will still export as normal PNGs, but PNG-8 only supports 256 colors and doesn’t allow partial transparency, netting you a smaller file size than the more full-featured PNG-24. You may also run across PNG-8 and PNG-24 in some programs. The file size is generally bigger than either GIF or JPEG, but PNG preserves quality better and is more flexible, PNG was originally designed as a GIF alternative, but it supports way more colors and is more flexible about transparency settings. This format has become the go-to for high-quality web graphics, especially if you need a transparent background. Portable Network Graphics (PNG) – Lossless Raster Great for: putting photos on the Web, saving and sending small image sizes, general use, printing out pictures. JPEG-2000 is the updated version that has some improvements over the original, but it’s never really taken off, so you’re unlikely to see this format many places. Your eye probably couldn’t tell a lightly-compressed JPEG from a higher-quality image without a few seconds of scrutiny, and it loads fast, so it’s good enough for most of the Web. The JPEG file is named after the group that created it and dominates the world of web images due to its near-universal compatibility and small size. Joint Photographic Experts Group (JPEG) – Lossy Raster The image can get as big or as small as you need without taking a quality hit, but these extensions are not as common around the Web since vectors are not as readily compatible as raster images. SWF, EPS, and PDF files store images not as pixels, but as math equations that can be rendered as points and lines. Vectors, though, are designed to be scaled forever. The only information they have is what color the pixels are, so enlarging or stretching them will generally just result in a more pixelated image. JPG, PNG, GIF, TIFF, and most other photo files are rasters. has nothing to do with Bob Marley – it just means that the file is essentially a grid of colored pixels that make a picture. When you think “image format,” you’re probably thinking of a raster. Lossless compression just rearranges the data in such a way that it takes up less space but can be packed and unpacked (or unzipped!) without any damage to the file. Lossy compression cuts down on file sizes by permanently deleting information about a file, making it smaller but also degrading the quality. LosslessĮvery image format can be categorized as either “lossy” or “lossless,” and these terms mostly explain themselves. Please Go through below details for better reach.
