What is AVIF Image Format?

AVIF stands for AV1 Image File Format. It’s a new type of image file that’s becoming popular because it keeps high-quality images while making the file size much smaller. 

It is built on the AV1 video codec, which means it can achieve better compression than older formats. 

This results in smaller file sizes without a noticeable loss in image quality. This means your website can load faster without sacrificing image quality. 

AVIF is gaining popularity as more web browsers begin to support it. Its efficient compression and high-quality output make it suitable for various applications, from web design to digital photography.

How does AVIF Image Format Work?

AVIF works by using a special type of video compression technology called AV1 codec. Normally, this codec is used to shrink videos without making them look blurry. 

It takes that same powerful compression and applies it to single images instead of full videos. 

Because of its advanced encoding method, it’s like having a smart filter that decides what parts of the image need the most detail, and what can be simplified without anyone noticing.

Pros and Cons of Using AVIF Images

What is WebP Image Format?

Webp image format avif vs webp: which one helps in improving site performance? From the plus addons for elementor

WebP is a modern image format developed by Google in 2010 that is designed to make your website faster. It compresses your images to smaller file sizes without losing much quality. 

This means your images look great, but they load faster, making your site quicker and more user-friendly.

This format supports both lossy and lossless compression. 

  • Lossy Compression: This reduces file size by removing some image data. The result is a smaller file with some quality loss, often suitable for web use.
  • Lossless Compression: This maintains the original image quality. It compresses the file without losing any pixel data.

WebP images are about 25-35% smaller than JPEG and PNG images. So, they use less storage space and load faster on your site.

Even though the file size is smaller, the image quality is still very good. You won’t notice much difference compared to JPEG or PNG.

It’s ideal for websites where performance matters, such as blogs, online stores, and portfolios. 

The best thing is now WordPress the 5.8 version of WordPress also started supporting WebP image file format without needing any extra plugins.

How WebP Image Format Work?

WebP works by shrinking down your image file size while keeping the important parts clear and sharp.

It cuts out extra information you can’t see in your image, like tiny details or repetitive patterns. This helps make the file smaller without changing how the image looks to your eyes.

For photos (like JPEG images), WebP uses a method that focuses on removing small details that won’t be noticed much and for images with transparency (like PNG images), WebP finds a way to keep the see-through parts while still reducing the file size.
