Difference between PNG-8 and 24

Difference between PNG-8 and 24

When creating or editing images for the web, you may be wondering which file format to use. PNG-8 and PNG-24 are both popular formats, but they have different uses. In this blog post, we’ll explore the difference between PNG-8 and PNG-24, and when to use each one.

What is PNG-8?

PNG-8 is a type of PNG file that uses 8-bit color. PNG-8 files are smaller than PNG-24 files and can be used for images with fewer colors, such as line art or logos. PNG-8 files support transparency and interlacing and can be saved with or without a background color. PNG-8 is not supported by all web browsers, but it is compatible with most image editing programs. When saving a PNG-8 file, you will need to choose an optimization method, which will determine how the file is compressed. Generally, PNG-8 files are best suited for images with few colors and simple shapes.

What is PNG-24?

PNG-24 is a type of image file format that supports lossless compression. PNG-24 files are typically larger than PNG-8 or PNG-32 files, but the extra size is due to the fact that PNG-24 files contain more information. Unlike PNG-8 or PNG-32 files, which only support 8-bit or 32-bit color depths, PNG-24 files can support up to 24-bit color depths. This means that PNG-24 files can contain more than 16 million different colors, making them ideal for storing high-quality images. In addition, PNG-24 files support transparency, meaning that pixels can be set to partially transparent. This can be useful for creating images with smooth edges or for superimposing images on top of other images.

Difference between PNG-8 and 24

PNG-8 is a PNG format that uses 8 bits per color channel and is thus limited to a palette of 256 colors. PNG-24, on the other hand, uses 24 bits per color channel, allowing for nearly full-color images. The main advantage of PNG-8 over PNG-24 is that PNG-8 images are typically much smaller in file size, making them faster to download and view. However, PNG-8 images can sometimes appear “pixellated” or “blocky,” especially when viewed at high resolutions. PNG-24 images don’t suffer from this problem and can also contain transparency information, making them the preferred format for many applications.

Conclusion

So, what is the difference between PNG-8 and 24? The answer lies in how many colors are used to create an image. PNG-8 uses 8 bits per pixel while PNG-24 uses 24 bits per pixel. This means that PNG-8 can only produce 256 colors while PNG-24 can produce 16.7 million colors. For this reason, it is generally recommended to use PNG-24 whenever possible as it will give you a higher quality image with more color options. If you are working with images that will be displayed on the web, it is best to use the PNG-24 format to ensure the highest quality display.
