PNG and AVIF are two popular file formats used for digital images. PNG (Portable Network Graphics) is a lossless format that supports transparency and is widely used on the web. AVIF (AV1 Image File Format) is a relatively new format that offers higher compression efficiency than other image formats, resulting in smaller file sizes without compromising image quality.
Differences between PNG and AVIF
PNG files are popular on the web because of their ability to support transparency and their compatibility with most web browsers. However, their file size can be relatively large, which can result in slow loading times, especially for larger images. AVIF, on the other hand, is a more modern image format that offers better compression efficiency than other image formats, resulting in smaller file sizes without compromising image quality.
How AVIF achieves higher compression efficiency?
AVIF achieves this higher compression efficiency by using the AV1 video codec, which is an open, royalty-free video coding format developed by the Alliance for Open Media. The AV1 codec uses advanced compression techniques, such as intra-frame and inter-frame coding, to compress images more efficiently than other codecs.
Another advantage of AVIF is that it supports a wider color gamut than other image formats, including sRGB, HDR10, and Dolby Vision. This makes it a great format for displaying high-quality images on a variety of devices, including high-resolution displays and HDR-compatible devices.
In conclusion, converting PNG files to AVIF can result in smaller file sizes without compromising image quality, making it a great option for web designers and developers looking to improve the performance of their websites. While the process of converting PNG files to AVIF can vary depending on the software and tools used, the benefits of using AVIF for digital images are clear.
