What is the difference between JPG and PNG?

JPG is the  image format  that is most often used for sharing digital photographs. Its quality allows it to restore all the complexity of the shots: shadows, nuances, gradients. It draws from a repository of 16.7 million colors to achieve this.

The png was created to offer a free alternative to the gif. It has two levels of compression, one, png 8, very light but which can only display 256 colors, the other, png 24, heavier than JPG but with the same rendering in terms of hues.

At first glance, the JPG allows better image compression , but the png offers the possibility of managing transparent backgrounds, useful for montages. Their differences do not end there, however.

Why choose between JPG and PNG?

On your website, you'll want to offer visitors both the best possible image quality…and the fastest loading time.

It is for these two reasons that you will have to switch from JPG to PNG depending on the type of visuals that you want to highlight… and that you will not be content to apply the same format in all circumstances.

Your reflection could not stop there. You will have every interest in choosing the best compression software, those that will allow you to best reduce the weight of the image without altering it. Some even exist as a plug-in, for example for WordPress.

In general, avoid PNG 24, too heavy for the web. Experiment with different levels of compression to find the right balance. And don't forget to also plan that these same images will have to be resized  in order to be visible on the smallest screens of smartphones!
