A lot of people like to take a lot of photos during their travels, but when they come back from the trip they realize that the format may be different, and if they want to convert the format to their favorite format how can they do it? Converting photos to PNG format files is a requirement for many users, especially professionals. Because it is usually used in Java programs or web pages. So this article is going to show you how to convert images to PNG format on Windows/Mac.

Characteristics of PNG files

Small Volume:PNG format is preferred for web pages because it is small and ensures clear, realistic images.

Lossless Compression: PNG files are compressed using a special algorithm that results in a high compression ratio with no loss of data. It also uses a special coding method to mark recurring data, thus having no effect on the color of the image and no loss of color is possible, so that it can be saved repeatedly without degrading the image quality.

Indexed Color Mode: The PNG-8 format uses an 8-bit color palette to convert RGB color images to indexed color images. The image is stored with a representative color number selected from it, and each number corresponds to a color, thus reducing the amount of data in the image, which is very beneficial to the dissemination of color images.

Optimized Network Transmission Display: When browsing PNG images on a web page, even interleaved images provide the viewer with a basic idea of what the image will look like before it is fully downloaded and then gradually becomes clearer.

Transparency Support: PNG can define 256 layers of transparency for the original image, allowing the edges of a color image to blend with any background, a feature that GIFs and JPEGs do not have.
