Why optimize your images?
Image optimization is crucial to provide an optimal user experience. It's important to note that images represent the heaviest element within a campaign. Compressing these images will, therefore, reduce the overall weight of the campaign. By reducing the size of graphic files, several advantages arise both in terms of performance and impact on SEO and the environment.
Here are some of the benefits of image compression:
- Accelerated page loading.
- Image compression is appreciated by search engines, leading to improved Google rankings.
- Reduced bandwidth consumption due to lighter images, allowing faster display even with a weak internet connection.
- Significant ecological advantage by reducing the space required on servers.
- Subsequent positive impact on conversion rates and user engagement.
How to optimize your images?
Which image format to choose?
Before making any modifications to your images, make sure to choose the most suitable format. The choice of format contributes to enhancing performance according to specific needs.
- JPG is suitable for image compression. However, this results in a decrease in image quality, and this loss of quality is irreversible.
- PNG is of better quality but also heavier than JPG. Its main advantage is that it also allows for transparency management.
- GIF is primarily used for animated images. GIF images can use a color palette limited to 256 colors and also support transparency.
- SVG is an ideal vector format for simple illustrations or logos.
Conversion tip: There are online tools like cloudconvert that allow you to convert one format to another.
Transparency tip: The website remove.bg makes it easy to remove the background of an image to make it transparent using online tools.
Optimizing image weight:
The goal of optimizing your images is to strike a balance by reducing the file size while maintaining good quality. We recommend a maximum file size of 1 MB per image.
This is very simple to do as soon as you have a compression tool.
You can use online image compression tools like TinyPNG, Compressor.io, imagecompressor.com or software such as Photoshop, ImageOptim.
Why are my images pixelated?
Make sure to use images with a resolution high enough to maintain sharpness.
High-resolution screens, also known as Retina displays, have a very high pixel density, to the point where the human eye can no longer discern individual pixels.
Many smartphones, tablets, and computers come with high-definition screens. This is why phone screens generally require a higher pixel density than some computers.
Therefore, it is sometimes necessary to use high-resolution images to ensure optimal display quality.
Tip: Many software programs offer the option to export images in x2 size for high-resolution screens.
