How to Choose the Right File Format for Your Images

Choosing the right file format for your images is essential in order to ensure that they look as good as possible and are optimised for the web. Different image formats have different advantages and disadvantages, so it’s important to understand what each one is best used for. We’ll discuss the differences between common file formats such as JPG, PNG, and GIF; how they compare in terms of quality, size, and compatibility; and when each of them should be used.

JPG files for image SEO

What are the benefits of JPG files for image optimisation and SEO?

The main benefit of using JPG is that it offers a lot more compression than PNG, which makes the image file smaller in size. Additionally, since JPEG is an industry standard, it’s much more likely to be compatible with your intended audience.

What are the drawbacks of using JPG files for image optimisation and SEO?

Since it’s such a popular format and is much easier to optimise for compression, there aren’t as many options when editing files inside programs like Photoshop and image quality will suffer. Therefore, this is a disadvantage for people who prefer to work with raw files.

PNG files for image SEO

What are the benefits of PNG files for image optimisation and SEO?

PNG’s offer several advantages over other image formats, including lossless compression, support for transparency, and better color accuracy. They have an 8-bit color depth in RGB (48 colors) while other formats have 16 or 256 colors. As a result, PNGs are often the best choice when it comes to quality. They are commonly used for web graphics as well as logos and icon files.

What are the drawbacks of using PNG files for image optimisation and SEO?

PNG has a lossy compression, meaning that it discards data and cannot do true transparency. It can also result in visible artifacts such as banding and blocking artifacts on some monitors. GIFs have a better compatibility than PNG with both browsers and image viewers and are also much smaller than PNG.

GIF files for image SEO

What are the benefits of GIF files for image optimisation and SEO?

Alongside having better compatibility than PNG’s, GIF’s support true transparency by allowing users to show what they mean in a single image rather than having to explain it with words. This makes it easier for people to understand the message being conveyed and makes communication more efficient. Additionally, GIFs can also help increase engagement with audiences as they are visually attractive and entertaining, making them more likely to be shared or liked on social media platforms.

What are the drawbacks of using GIF files for image optimisation and SEO?

GIFs are limited in size and resolution, so they cannot be used for high-resolution photos or videos. Additionally, GIFs can slow down website loading times if not optimised properly and can also consume a lot of bandwidth.
