History of PNG
The PNG format was first created in the year of 1995, at a period when the GIF format was already well established. To keep pace with screen technology, it needed a more advanced file format, which was able to support a much broader range of colours.
A group of developers then combined forces to create the PNG format, and a decision was made to support a single, static image in the new image package. The first version of the file format was established in October 1996, after which it became an international standard in 1998, 1999 and 2003.
When to use a PNG
PNG files can often be bigger than GIF files, so it is worth considering whether the file format is definitely the best option of use case. For instance, if you have lots of images on one web page, you might want to suggest either resizing the image to better quality, or using an alternate image format that results in a smaller file size.
This transfer can result in the loss of picture quality, so if you need to preserve consistency, PNG is definitely the best option and worth having, even if it is a big format.
How to access a PNG file and change it
PNG files can be accessed in any web browser, such as Firefox, Chrome, Edge, Safari and Opera, as it is now the most commonly used type of web image. If you don’t have an image viewer on your computer, even if you can’t edit it that way, you can access it by moving it from your phone to your browser.
A PNG file can also be opened and updated in most image editing programs, such as Microsoft Paint (although Microsoft will soon end support for the image editing program), Paint 3D, GIMP, XnView and, of course, Adobe Photoshop.
If you are not aware that an image editor is already enabled on your device, double-click the image file and any compatible software can open it for you to edit.
How to convert a PNG file
Of course, if you want, you can transform a PNG file to any other popular format like JPG, ICO, TIF, BMP, and GIF. This can be done by a wide variety of free online converters, including XnConvert, Zamzar, Zigzag and Adapter.
Uses of PNG:
PNG can be used for:
- Line art photos, such as paintings, sketches and comics.
- Images or text samples, such as handwritten letters or documents in the newspaper.
- Charts, labels, maps, plans for architecture and designs.
- Anything with text, including page templates in Photoshop or InDesign, saved as photos.
Advantages of PNG
The PNG format advantages include:
- Lossless compression— After compression of the file, do not lose detail and quality.
- Supports a large number of colours— For various types of digital images, including photos and graphics, the format is suitable.
- Transparency support— Supports digital image compression with transparent regions.
- Great for image editing–Lossless compressions make it ideal for digital image editing storage.
- Sharp edges and strong colours— Perfect for text, line arts and graphic images.
Lightning Png Transparent Background 2019: Lightning is likewise one of the most destructive normal wonders known to man. With jolt temperatures more smoking than the outside of the sun and shockwaves radiating out every which way, lightning is an exercise in physical science and quietude.

Amazing lightning png
Past its amazing excellence, lightning presents science with one of its most noteworthy neighbourhood secrets: How can it work? It is regular learning that lightning is created in electrically charged tempest frameworks, yet the technique for cloud charging still stays slippery.
In this article, we will take a gander at lightning from the back to front with the goal that you can comprehend this marvel.
Lightning starts with a procedure that is less secretive: the water cycle. To completely see how the water cycle functions, we should initially comprehend the standards of vanishing and build-up.

Lightning is often trailed by thunder. Thunder is aloud sound produced by the shock wave that grows as vapours in the locality of the discharge include an unexpected upsurge in the pressure.
It usually happens throughout the thunderstorm and further types of energetic weather structures.
Lightning is split by the site they occur at: Inside a solitary thundercloud, among two dissimilar clouds, or amongst a cloud and the ground. The other categories of lightning are as mentioned below:
- Heat lightning- The heat lightning can be seen from a far distance but it cannot be heard.
- Dry lightning- Dry lightning causes forest fires.
- Ball lightning- The ball lightning is infrequently observed in the sky.

Electrostatic charge in Lightening
- The electrostatic charge arises when the two preconditions are completed. The primary condition is an extremely adequate potential variance amongst the two areas of space should exist.
- The second condition is that a high confrontation medium should hinder freely, unhampered equalization of the reverse charge.
- The atmosphere then offers the electrical lining or a barrier which dodges free equalization among the charged areas of contradictory polarity.

Lightning categorized png
The dissimilar types of lightning are well-defined as follows:
- Intracloud -Intracloudbefalls within a single thundercloud unit.
- Cloud to Cloud -The intercloud or cloud to cloud lightning befalls between start and end of the two different functional thundercloud units.

Positive and Negative lightning png
The cloud to ground lightning is either positive or negative. Maximum number of Cloud to ground lightning is negative which means that a negative charge is carried from ground and electrons travel descending way along with the lightning station.
The contradictory befalls in a positive cloud to ground flash lightning, where all the electrons travel ascendant along the lightning channel and a positive charge is passed to the ground. Positive lightning is least communal than the negative lightning.

The substances which are hit by lightning experience warmth and magnetic forces of countless magnitude. As the electrostatic release of earthly lightning superheats the air to plasma temperatures laterally with the length of the release station in a short period.
