JPEG is used for photographs and uses lossy compression to reduce file size, but information is lost in the process. The optimal file format depends on the image type and intended use.
Image Files Formats
There are several common graphic file formats for images, with TIFF, JPEG, and GIF being the most widely used. The best format depends on factors like the image content, intended use, need for editing, and compatibility. TIFF is a versatile, lossless format best for master copies. JPEG uses lossy compression and is best for photos. GIF is limited to 256 colors but works well for logos and is widely compatible. The document provides details on the characteristics and use cases of various formats.
Compressed image file formats
This chapter introduces fundamental concepts of image file formats. It discusses how images are represented as arrays of pixels on displays and in memory. Vector graphics store images as drawing commands, while bitmap graphics represent each pixel directly. Bitmap formats are better for photos but require more storage. Common bitmap formats are covered in this book, which use techniques like color reduction, compression, and ordering to reduce file sizes.
Digital graphics file formats
This document discusses different types of digital file formats for graphics, including raster formats like JPEG, TIFF, GIF, BMP, and vector formats like PSD, AI, FLA, and WMF. It describes the key characteristics of each format such as whether they are bitmap or vector images, if they support compression and layers, common uses, and advantages and disadvantages. The document also covers topics like compression, optimizing files, and different methods of capturing digital images.
Image File Fomat
Image file formats dictate how digital images are stored and interpreted. Pixels that make up pictures are arranged according to the specific format. Common formats include JPEG, which uses lossy compression to greatly reduce file sizes while retaining image quality. TIFF can use either lossless or lossy compression. GIF is popular for images with fewer colors and uses lossless compression, supporting up to 256 colors. PNG was created as a free, open alternative to GIF and also uses lossless compression, making it suitable for editing applications.

Flickr is a photo sharing website where users can upload and view photos. It allows users to store photos online in a central repository that bloggers can then access for use in their blogs. While commonly used for recreational photo sharing, Flickr also has potential academic uses as it provides a way to store and access photos for educational or research purposes.
Image And Graphic Files on Powerpoint
Bitmap images store pixels while vector images use mathematical formulas to define shapes. JPEGs are for photos and use lossy compression, while GIFs are for images with few colors like logos and use lossless compression. Embedded images are stored within documents, while linked images reference external files. Color palettes define the available colors in indexed color images, with smaller palettes for GIFs and larger for TIFFs. Lossless compression reduces file size without quality loss, unlike the lossy compression typically used by JPEGs. PNGs are recommended as they are lossless like GIFs but overcome limitations of GIFs and JPEGs. BMPs should be avoided due to their large size and lack of browser
File formats
Raster graphics are digital images made up of a grid of pixels, while vector graphics use mathematical expressions like points and lines. Raster files like JPEG are commonly used for photos due to their small file size but can lose quality with compression, while vector files like AI maintain quality but have difficulty storing complex images. When storing and sharing graphics files, it is important to consider file type, size, naming conventions, and folder organization to optimize quality, speed, and ease of access.
File Formats Re-Submission
File formats are designed to store specific types of information like images. JPEG is a lossy compression format suitable for photos, while PNG is a lossless format that can compress solid colors and is more supported than GIFs, which can animate but have a limited color palette. PSD files are layered Photoshop documents, TIFFs are standard for scanning, and RAW files store unprocessed camera data for more editing control, though they are larger files. Vector formats like EPS contain paths rather than pixels and can scale smoothly.
Image And Graphic Files
Vector images use mathematical formulas to create shapes rather than pixels, making them easier to manipulate without quality loss. Bitmap images are composed of pixels arranged in a grid, with each pixel assigned a color value. GIF images are suitable for drawings and images with a limited color palette, while JPEG is better for photos as it can heavily compress files sizes with some quality reduction each time the image is saved. Embedded graphics become part of the file they are inserted into and move with the file, while linked images remain separate but connected files. Lossless compression allows for original data to be stored in a reduced format without quality loss, like with ZIP and PNG files, while JPEG is commonly used for photos with some quality degradation each time it is saved
File formats and its types
The document discusses various file formats for different types of digital files. It begins by defining what a file format is and how it specifies how information is encoded for storage. It then provides examples of common image, audio, video, and text file formats. For each type of file, it lists some of the most popular specific formats like JPEG, PNG, MP3, WAV, AVI, DOC, HTML, and PDF. It provides brief descriptions of each format including what they are called, their file extensions, how they compress or store data, browser support, and common uses. The document serves to introduce and compare some of the most widely used file formats.

- 1. LESSON 3 ONLINE FORMATS FOR IMAGES AND TEXTS
- 2. Graphics files store an image and are divided into two basic types: >raster-based >vector based files
- 3. RASTER-BASED FILES →Stores the image as a collection of pixels →Cannot be scaled without distortion
- 4. Common types of raster-based file formats → Joint Photographic Experts Group (JPEG) – it supports wide range of colors that makes it most popularly used on camera and scanners. This type is commonly used in the Internet and photo sharing. Though, some details can be affected when producing a smaller file size. → Joint Photographic Experts Group (JPEG2000) – it is an evolving format of the JPEG developed with multiple compression techniques based on wavelet technology. → Tagged Image File Format (TIFF) – it is the often format choice for high-quality master image because its quality is as perfect as the original. File size can be huge. It is commonly used when sending image to be included on printed books, brochures, or magazines.
