While this allows for numbers of arbitrary precision to be serialized, it may lead to portability issues. For example, since no differentiation is made between integer and floating-point values, some implementations may treat 42, 42.0, and 4.2E+1 what are NWC files as the same number, while others may not. Open a Text editor like Notepad, Visual Studio Code, Sublime, or your favorite one. Copy and Paste below JSON data in Text Editor or create your own base on the What is JSON article.

Where an image contains both sharp transitions and photographic parts, a choice must be made between the two effects. One downside to GIF files is that they use the 256-indexed color palette, which limits color choice and can leave photos looking flat and lackluster. GIF files are also saved in a single-layer format, meaning all edits are saved into one image layer and cannot be reverted. While a small file size is ideal for presentation and web page load times, GIF limitations should be taken into consideration before selecting this file format. Radiance is a 32‑bits-per-channel file format used for HDR images.


Double-click the photo is the common way to open files. The frequently used photo app is Windows Photo Viewer (Built-in), IrfanView, and more. Also, if you use another photos viewer, you can right-click photos, choose “Open with” to run another photo checker. If you absolutely need a clear image with no JPG compression artifacts, PNG is your choice.


The PNG format is lossless, meaning that it preserves the quality of the image while providing a smaller file size than other lossy formats such as JPEG. Because of these qualities, PNG is often used for web graphics, such as logos and icons. The PNG format was created in 1995 as a way to provide lossless compression for images on the web. Lossless compression means that when an image is compressed in the PNG format, there is no loss of quality. This is in contrast to formats like JPEG, which use lossy compression, meaning that some quality is lost when an image is compressed in that format. The WebP format can compress smaller than both PNGs and JPEGs, but keep solid resolution.

You can use 7-Zip on any computer, including a computer in a commercial organization. 7-Zip works for Windows 7, Vista, XP, 2008, 2003, 2000, NT, ME, and 98. And there is a port of the command line version to Linux/Unix. Most of the source code is under the GNU LGPL license.

For regular blog posts or header images, JPEG offers more than good enough quality with significantly lower file size. You can often save up to 50% or more space while struggling to spot any difference in quality with the naked eye. The main difference between PNG and JPEG is that PNG is a lossless image format, while JPEG is a lossy one. This basically means that PNG uses compression techniques without sacrificing the original quality or detail of the image. These two factors, along with its universal browser and OS support, make it the most popular image file type on the web. Since it uses lossless compression, it’s also used by designers and photographers to showcase high-quality pictures on their portfolio websites for example.

Full nameCSV, Comma Separated Values DescriptionCSV is a simple format for representing a rectangular array of numeric and textual values. It is a delimited data format that has fields/columns separated by the comma character %x2C and records/rows/lines separated by characters indicating a line break. RFC 4180 stipulates the use of CRLF pairs to denote line breaks, where CR is %x0D and LF is %x0A .
