What is .jpg format?

Question

Pls. mention the steps to prepare a document in .jpg format.

Answer 1

.JPG file extension, pronounced Jay Peg. This is the right format for those photo images which must be very small files, for example, for web sites or for email. JPG is often used on digital camera memory cards, but RAW or TIF format may be offered too, to avoid it. The JPG file is wonderfully small, often compressed to perhaps only 1/10 of the size of the original data, which is a good thing when modems are involved. However, this fantastic compression efficiency comes with a high price. JPG uses lossy compression (lossy meaning "with losses to quality"). Lossy means that some image quality is lost when the JPG data is compressed and saved, and this quality can never be recovered.

Answer 2

First off, a picture (graphic) is prepared in JPG not a document.

In computing, JPG or JPEG (pronounced JAY-peg) is a commonly used method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the standard. The group was organized in 1986, issuing a standard in 1992 which was approved in 1994 as ISO 10918-1. JPEG is distinct from MPEG (Moving Picture Experts Group) which produces compression schemes for video.

The JPEG standard specifies both the codec, which defines how an image is compressed into a stream of bytes and decompressed back into an image, and the file format used to contain that stream. The compression method is usually lossy compression, meaning that some visual quality is lost in the process, although there are variations on the standard baseline JPEG which are lossless. There is also an interlaced "Progressive JPEG" format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed whilst downloading over a slow connection, allowing a reasonable preview before all the data has been retrieved. However, progressive JPEGs are not as widely supported.

Answer 3

.jpg(JPEG- Joint Picture Expert Group) is an extension of image file. The jpg images are light weight and suitable for web for quick loading. You can use image editing softwares like Adobe Photoshop etc to create a jpg file or "Save As" existing file in JPEG format.

Answer 4

jpg is a photo image. For example, when you download pictures from your digital camera they are generally jpg files.

I'm not sure what you mean about preparing a document in jpg. Sorry.

Answer 5

As the other people are saying .jpeg is a picture format; if you put a document into .jpeg you will have it as a picture and will not be able to use a word processor. All the words will be one photograpg. If you are trying to compress a document it is better to use the program WINZIP. You can download it free. If you really want the document in .jpeg format scan it and "save as .jpeg".

In computing, JPEG (pronounced JAY-peg; IPA: [ˈdʒeɪpɛg]) is a commonly used method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the standard. The group was organized in 1986, issuing a standard in 1992 which was approved in 1994 as ISO 10918-1.

The JPEG standard specifies both the codec, which defines how an image is compressed into a stream of bytes and decompressed back into an image, and the file format used to contain that stream. The compression method is usually lossy compression, meaning that some visual quality is lost in the process, although there are variations on the standard baseline JPEG which are lossless. There is also an interlaced "Progressive JPEG" format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed whilst downloading over a slow connection, allowing a reasonable preview before all the data has been retrieved. However, progressive JPEGs are not as widely supported.

The file format is known as 'JPEG Interchange Format', as specified in Annex B of the standard. This is often confused with the JPEG File Interchange Format (JFIF), a minimal version of the JPEG format that was deliberately simplified so that it could be widely implemented and thus become the de-facto standard. Most image editing software programs that write to a "JPEG file" are actually creating a file in JFIF format.[1]

Image files that employ JPEG compression are commonly called "JPEG files". The most common file extension for this format is .jpg, though .jpeg, .jpe, .jfif and .jif are also used. It is also possible for JPEG data to be embedded in other file types, such as TIFF format images.

JPEG/JFIF is the format most used for storing and transmitting photographs on the World Wide Web. For this application, it is preferred to formats such as GIF, which has a limit of 256 distinct colors that is insufficient for color photographs, and PNG, which produces much larger image files for this type of image. The JPEG compression algorithm is not as well suited for line drawings and other textual or iconic graphics, and thus the PNG and GIF formats are preferred for these types of images.

Answer 7

JPEG is a poor quality image format that takes up much space and leaves much clutter around your image, while PNG and BMP do not. PNG, BMP, and SVG are superior to JPEG.

How to prepare a file in PNG:
Open the file in Microsoft Paint. If you change the extension only, you will not actually be changing the format.
Click "Save as." Then select "PNG picture."
Enter the filename and location and click "Save."

How to degrade and distort a picture:
Open the file in Microsoft Paint.
Click "Save as."
Click "JPEG picture."
Enter the filename and location, then click "Save."

Warning: Keep a PNG copy of your photo or picture.
