# What is a PNG image?

Understand what a PNG image is, its characteristics and advantages over other image formats such as JPEG and GIF, and in which areas PNG is best suited.

## What is a PNG image?

PNG (Portable Network Graphics) is a lossless image format developed as an alternative to GIF and is widely used on the web. It supports millions of colors, variable transparency and lossless compression. Compared to other image formats such as JPEG or GIF, PNG offers higher image quality, stronger compression and improved web functionality. Characteristics of PNG Files Lossless Compression: Unlike JPEG, which loses some details when saving an image, PNG maintains full image quality while compressing the file size. This is particularly useful for images with sharp edges and distinct colors, such as text, logos, and illustrations. Transparency: PNG supports alpha channels and variable transparency levels, i.e. This means that images can be shown on different colored or textured backgrounds without visible edges or unwanted pixels. Color Palette: While GIF is limited to a color palette of 256 colors, PNG supports up to 16 million colors, also known as Truecolor. This allows for a more realistic representation of photographs and complex images. Interlaced display: PNG enables so-called interlacing, which allows web images to be displayed gradually as they load. This improves the user experience because page visitors don't have to wait for an image to fully load. Disadvantages of PNG Files File Size: Using PNG for complex images and photographs typically results in larger files compared to other formats such as JPEG. These larger file sizes can result in longer loading times and increased traffic, which can impact user experience. Browser Compatibility: Although PNG is supported by most modern browsers, older browser versions may have problems displaying PNG images. Conclusion PNG is a versatile and lossless image format that is well suited for images with sharp edges, hard colors and transparency. It offers high quality images and improved web functionality compared to other file formats such as GIF or JPEG. However, larger file sizes and possible browser compatibility problems with older browser versions must be taken into account.

## Properties of PNG files

-   **Lossless Compression:** Unlike JPEG, which loses some details when saving an image, PNG maintains full image quality while compressing the file size. This is particularly useful for images with sharp edges and distinct colors, such as text, logos, and illustrations.
-   **Transparency:** PNG supports alpha channels and variable transparency levels, i.e. This means that images can be shown on different colored or textured backgrounds without visible edges or unwanted pixels.
-   **Color Palette:** While GIF is limited to a color palette of 256 colors, PNG supports up to 16 million colors, also known as Truecolor. This allows for a more realistic representation of photographs and complex images.
-   **Interlaced display:** PNG allows what is known as interlacing, which allows web images to be displayed gradually as they load. This improves the [user experience](/en/services/webdesign-and-conception/) because page visitors don't have to wait for an image to fully load.
