JPEG format

 

What is JPEG format good and bad for?

Answer: JPG format is a lossy compressed file format. This makes it useful for storing photographs at a smaller size than a BMP. JPG is a common choice for use on the Web because it is compressed. For storing line drawings, text, and iconic graphics at a smaller file size, GIF or PNG are better choices because they are lossless.

PNG format is a lossless compression file format, which makes it a common choice for use on the Web. PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size.

JPEGs are for photographs and realistic images. PNGs are for line art, text-heavy images, and images with few colours. GIFs are just failed.

  

What is the file format?

Answer: A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. Some file formats are designed for very particular types of data: Docx file for Ms word, PNG files, for example, store bitmapped images using lossless data compression.

A file format defines the structure and sort of knowledge stored during a file. The structure of a typical file may include a header, metadata, saved content, and an end-of-file (EOF) marker. the info stored within the file depends on the aim of the file format. Some files, like XML files, are wont to store lists of things, while others, like JPEG image files, simply contain a block of knowledge.

The file format is the structure of a file that tells a program the way to display its contents. for instance, a Microsoft Word document saved within the . DOC file format is best viewed in Microsoft Word. albeit another program can open the file, it's going to not have all the features needed to display the document correctly.

Programs compatible with a file format could also be ready to give a summary of a file but might not be ready to display all the file features. Also, with some programs opening a file format that's not supported may offer you garbage.

A file format also defines whether the info is stored in plain text or binary format. Plain text files are often opened and viewed during a standard text editor. While text-based files are easy to make, they often spend more room than comparable binary files. They also lack security, since the contents are often easily viewed by dragging the file to a text editor. computer file formats are often compressed and are well-suited for storing graphics, audio, and video data. If you plan to view a computer file during a text editor, most of the info will appear garbled and unintelligible, but you'll see some header text that identifies the file's contents.

Some file formats are proprietary, while others are universal, or open formats. Proprietary file formats can only be opened by one or more related programs. for instance, a compressed StuffIt X (.SITX) archive can only be opened by StuffIt Deluxe or StuffIt Expander. If you are trying to open a StuffIt X archive with WinZip or another file decompression tool, the file won't be recognized. Conversely, open file formats are publicly available and are recognized by multiple programs. for instance, StuffIt Deluxe also can save compressed archives during a standard zipped (.ZIP) format, which may be opened by nearly all decompression utilities.

When software developers create applications that save files, choosing an appropriate file format is vital . for a few programs, it'd add up to use an open format, which is compatible with other applications. In other cases, employing a proprietary format may give the developer a competitive advantage, since the files created with the program can only be opened with the developer's software. However, most of the people like better to have multiple software options, numerous developers have moved faraway from proprietary file formats and now use open formats instead. for instance, Microsoft Word, which wont to save data processing documents within the proprietary. DOC format now saves documents within the open. DOCX format, which is supported by multiple applications.

NOTE: While the term "file format" technically refers to the structure and content of a file, the term is additionally used interchangeably with "file type," which defines a selected sort of file, like an upscale document or a Photoshop document.
