Which image format offers the best compression rate?

When it comes to image format and compression rate, there are a few different options available. JPEG is the most common and widely used format, as it offers good compression rates while still maintaining a high-quality image.

PNG is another popular format that offers better lossless compression but at the cost of a larger file size. GIFs are also often used for web graphics due to their small file size, however they only offer 256 colors and no transparency.

Finally, WebP is a newer image format that offers an even higher quality than JPEG with better compression rates - making it the optimal choice for web images. Ultimately, WebP is the best choice if you want to achieve the highest possible compression rate for your images.

Larger images hinder page access speeds that's why image compression matters a lot in page load speed. Website speed is one of the core web vitals to rank a website on Google. Compressed images require less bandwidth during transmission over the internet, which in turn reduces network congestion and speeds up content delivery.
