Online File Formats for Images and Text MEMBERS: Cañeda Torrevillas IMAGE FILE FORMATS Image File Formats  Image Formats bring different ways to overcome the problem of delivering an image with reduced file size and minimum download time.  Image File Formats are standardized means of organizing and storing digital images.  Image files are composed of digital data in one of theses formats that can be rasterized for use on a computer display or printer. LOSSLESS VS LOSSY  Lossless image formats capture all of the data of your original file. Nothing from the original file, photo, or piece of art is lost—hence the term “lossless.” The file may still be compressed, but all lossless formats will be able to reconstruct your image to its original state.  Lossy image formats approximate what your original image looks like. For example, a lossy image might reduce the amount of colors in your image or analyze the image for any unnecessary data. These clever technical tricks will typically reduce the file size, though they may reduce the quality of your image.  Typically, lossy files are much smaller than lossless files, making them ideal to use online where file size and download speed are vital.  Raster Images Raster images are typically used for photographs, Raster images are made digital artwork and web up of a set grid of dots graphics (such as banner called pixels where each ads, social media content pixel is assigned a color. and email graphics). Raster Images   JPEG is a lossy raster format that stands for Joint Photographic Experts Group, the technical team that developed it.  This is one of the most widely used formats online, JPEG/JPG typically for photos, email graphics and large web images like banner ads.  JPEG images have a sliding scale of compression that decreases file size tremendously, but increases artifacts or pixilation the more the image is compressed.   You’re dealing with online photos and/or artwork. JPEGs offer you the most flexibility with raster editing and compression making them ideal for web images that need to be You should downloaded quickly.  You want to print photos and/or artwork. At use a JPEG high resolution files with low compression, JPEGs are perfect for editing and then when… printing.  You need to send a quick preview image to a client. JPEG images can be reduced to very small sizes making them great for emailing. JPEG/JPG GIF  GIF is a lossless raster format that stands for Graphics Interchange Format.  GIF is also a widely used web image format, typically for animated graphics like banner ads, email images and social media memes.  You should use a GIF when…  You want to create web animation. GIF images hold all of the animation frames and timing information in one single file. Image editors like Photoshop make it easy to create a short animation and export it as a GIF.  You need transparency. GIF images have an “alpha channel” that can be transparent, so you can place your image on any colored background.  You need a small file. The compression techniques in the GIF format allow image files to shrink tremendously. For very simple icons and web graphics, GIF is the best image file format. GIF PNG  PNG is a lossless raster format that stands for Portable Network Graphics. Think of PNGs as the next-generation GIF.  This format has built-in transparency, but can also display higher color depths, which translates into millions of colors.  PNGs are a web standard and are quickly becoming one of the most common image formats used online.  You should use a PNG when…  You need high-quality transparent web graphics.  You have illustrations with limited colors.  You need a small file. PNG files can shrink to incredibly tiny sizes—especially images that are simple colors, shapes or text. This makes it the ideal image file type for web graphics. PNG   TIFF is a lossless raster format that stands for Tagged Image File Format. Because of its extremely high quality, the format is primarily used in photography and desktop TIFF/TIF publishing.  You’ll likely encounter TIFF files when you scan a document or take a photo with a professional digital camera.  You should use a TIF when…  You need high-quality print graphics.  You are making a high-quality scan. Using TIFF to scan your documents, photos and artwork will ensure that you have the best original file to work off of. TIF/TIFF   A raw image format contains the unprocessed data captured by a digital camera or scanner’s sensor.  Raw images store the unprocessed and RAW processed data in two separate files, so you’re left with the highest quality image possible that you can edit non-destructively with a photo editing application like Photoshop. You should use a Raw when…  You are shooting and editing photos. Make sure your camera is set to RAW so you can capture the most versatile image. Then, use a compatible photo-editing application to adjust your image. Raw   PSD is a proprietary layered image format that stands for Photoshop Document.  These are original design files created in Photoshop that are fully editable PSD with multiple layers and image adjustments.  PSDs are primarily used to create and edit raster images, but this unique format can also contain vector layers as well, making it extremely flexible for a number of different projects.   You need to edit artwork for digital or print. That could be a photo, painting, drawing, or anything else. Photoshop is the right tool to make sure every line, You should use shadow and texture is in place.  You want to get fancy with animation and a PSD when… video. Photoshop makes it easy to cut together simple video clips and add graphics, filters, text, animation and more. PSD  Vector Images When you shrink or enlarge a vector Vector images are essentially giant image, your shapes get larger, but math equations, and each dot, line you won’t lose any detail or get any and shape is represented by its own pixelation. Because your image will equation. Every “equation” can be always render identically, no matter assigned a color, stroke or thickness the size, there is no such thing as a (among other styles) to turn the lossy or lossless vector image type. shapes into art. Unlike raster images, Vector images are typically used for vector images are logos, icons, typesetting and digital resolution independent. illustrations. Vector Images   PDF stands for Portable Document Format and is an image format used to display documents and graphics correctly, no matter the device, application, operating system or web browser. PDF  At its core, PDF files have a powerful vector graphics foundation, but can also display everything from raster graphics to form fields to spreadsheets. Because it is a near universal standard, PDF files are often the file format requested by printers to send a final design into production.  You should use a PDF when…  You’re ready to print.  You want to display documents on the web. You wouldn’t use a PDF for a single icon or logo, but it’s great for posters, flyers, magazines and booklets. PDFs will keep your entire design in one package, making it easy to view, download or print. PDF   EPS is an image format that stands for Encapsulated PostScript.  Although it is used primarily as a vector EPS format, an EPS file can include both vector and raster image data.  Typically, an EPS file includes a single design element that can be used in a larger design.  You should use a EPS when…  You need to send a vector logo to a client, designer or a printer. With an EPS file, you don’t have to worry about where the logo will be placed or printed. No matter the size, it will always appear at the correct resolution. EPS   AI is a proprietary vector image format that stands for Adobe Illustrator. AL  Like those formats, AI files are primarily a vector-based format, though they can also include embedded or linked raster images. You should use a AL when… 1 2 3 You need to edit a You need to You need to set vector design. create a logo, type for a logo. icon or brand mascot. AL Text File Formats Image File Format  Files in the text file format are files in which the bytes represents the text characters of a particular character set using a specific system to relate the brinary numbers in the file to the text characters of the set.  The text file format includes a number of different formatting strategies for the text files in which data fields are structured in a regular pattern.   DOC/DOCX  RTF TYPES OF TEXT  TXT FILE FORMAT  HTML  PDF  ZIP   Microsoft’s Word (word processing) software saves documents using the.doc filename extension DOC/DOCX  These files contain special formatting codes that identify how the text with look ( bold, italic, color, typeface, etc.)as well as how the page lays out (margins, Indention, etc.)  RTF  Stands for Rich Text Format  RTF documents are designed to transfer documents between word processing software  These files use.rtf filename extensions TXT  TXT documents only contain text  This format only stores the text itself, with no information about formatting, fonts, page size, or anything like that  The details of the format are freely available and standardized   Stands for HyperText Markup Language  It use either.htm or.html filename HTML extensions  HTML files contain codes that browsers, like Internet Explorer or Safari, translate into web pages  PDF  Stands for Portable Document Format  PDF files use a.pdf filename extension  This software must be purchased and converts files created by other softwares, like Microsoft’s Word, into a read- only pdf file  In this format case, the text plus formatting, page size and similar information are stored in a moderately complex encoding   ZIP files are compressed data files  Files of ZIP format use the.zip filename extension ZIP  ZIP files can contain several compressed files under one filename, called an archive, when using the WinZip software   https://99designs.com/blog/tips/image-file- types/#raster References  https://www.slideshare.net/anugarg39501/file-formats- and-its-types
