The Five Different Types of Digital Image Files: TIFF, JPEG, GIF, PNG, and Raw Image Files, and When to Use Each. Images can be stored in one of five different formats. These include TIFF files, JPEG (Joint Photographic Experts Group) images, GIF (Graphics Interchange Format) images, PNG (Portable Network Graphics) images, and RAW images.
TIFF files are popular among photographers for three main reasons: they are reliable, they offer good image quality, and they can store lots of information. TIFF files use a combination of compression and meta data tags to reduce file size while still retaining most of the original image quality. They can also store many different types of photographs including black-and-white, color, and monochrome images.
JPEG files use compression to reduce the amount of space required on your computer's hard drive. This means that you can store more photos on your device - although you will need a lot of storage space if you want to be able to view them all later! JPEG files are popular because they provide excellent quality at very small sizes. They work by first dividing the photo into blocks called "cores" and then using various algorithms to determine which cores can be simplified or eliminated entirely without affecting the appearance of the image.
There are hundreds of picture file formats, including proprietary kinds. The most common image formats used on the Internet are PNG, JPEG, and GIF. Some of these visual forms are mentioned and briefly discussed below, divided into two graphic families: raster and vector.
JPEG (Joint Photographic Experts Group), TIFF (Tagged Image File Format), RAW DNG (Digital Negative Format), PNG (Portable Network Graphics), GIF (Graphics Interchange Format), BMP (Bitmap Image File), PSD (Portable Document Format) are the most often used formats (Photoshop Document). JPEG is a standard for compressing photographic data; it produces smaller files while retaining most of the original image quality. The JPG format is based on the JPEG standard, but it is not restricted to 8x8 blocks of pixels.
Image formats are collections of instructions that describe the arrangement of colors or shades in an image and how they should be interpreted by viewers or software programs. Different formats have different characteristics for these instructions. For example, the JPEG format is designed to reduce file size while maintaining image quality, so it uses lossy compression techniques. Other formats such as TIFF and RAW support lossless compression methods such as Lempel-Ziv & Welch encoding or CRC checksums that can store images with both white and black pixels without losing information.
Lossy vs Lossless: When you compress an image using lossy compression techniques such as JPEG, the quality of the image will decrease during conversion from RAW to JPEG, due to limitations of the technology. On the other hand, lossless compression methods retain the full quality of the image source. For this reason, lossless compression methods are usually applied to photos where image quality is important, such as wedding photographs or landscapes.
JPG, TIF, PNG, and GIF are the most commonly used image file formats for cameras, printing, scanning, and internet use. JPG is the most used image file format. JPEG files have the file extension JPG (Joint Photographic Experts Group, a committee of ISO and ITU). JPEG stands for Joint Photographic Experts Group and was developed by IBM in 1992. The file format was revised in 1996 with the addition of APP (Application Program Interface) compression to reduce file size further. In 1998, the standard was revised again to add EXIF (Exchangeable Image File Format) metadata to images. This allows applications that read or write JPEG files to extract this information.
TIFF (Tagged Image File Format) was developed by Adobe in 1988. It is a free software format that can be used with almost all modern imaging equipment. TIFF files have the file extension TIF (or TAG if you're working with Photoshop).
PNG (Portable Network Graphics) was developed as an alternative to JPG. It was designed to replace Gif as a format for web graphics. Like JPG, PNG uses lossy compression techniques but it reduces file size while still maintaining image quality. PNG files have the extension PNG (or PNR if you're working with Photoshop).
GIF (Graphics Interchange Format) was developed by CompuServe in 1987.

Bitmap pictures are often utilized in digital cameras, cellphones, and on the internet. JPEG, GIF, and PNG are examples of common bitmap image file formats. Bitmaps can be used to represent images such as photographs or drawings. They can also be used to simulate other types of media, such as text or music.
Because pixels are either turned on or off to display a bitmap image, the quality of the image is limited by the resolution of the bitmap. For example, a pixelated image will look poor when displayed at low resolutions.
The demand for high-quality bitmap images has led to the development of various techniques used to compress them so they can be stored using less space or transmitted over bandwidth-limited channels. These techniques include lossy compression methods such as JPEG and PNG, and lossless compression methods such as ZIP and RAR.
Lossy compression methods reduce the quality of the image to allow for large files to be stored more efficiently or to make them suitable for use with limited bandwidth connections. The trade-off for reduced quality is that the original image cannot be fully recovered. Lossy compression is useful when space is at a premium but quality needs to be maintained.
Graphic pictures are digitally saved in a few standardized graphic file formats, such as bitmap, TIFF, JPEG, GIF, and PNG; they can also be kept as raw, unprocessed data. Many visuals are developed in vector format and subsequently released as raster pictures. The term "graphics file" refers to all the information required to reproduce or play back an image.
A graphics file contains information about the colors, shapes, and other features of an image. It does this by assigning numbers to different elements of the picture. These numbers tell a computer what color to paint each element and where to put the elements on the page.
The most common type of graphics file is the bitmap file. Bitmaps are photographs that have been converted into bits (binary digits) that represent colors and patterns. Each pixel (picture element) in a bitmap is assigned a value of 1 or 0 based on whether it represents dark or light gray, for example. Pixels are combined together to form lines, shapes, and images. At the end of this process, you get a bitmap file that contains everything necessary to display the picture on a screen.
PNG (Portable Network Graphics) is a free, open source, lossless compressed file format for storing and exchanging graphics files on the Internet. It was designed by W3C (World Wide Web Consortium) for use with HTML web pages.
