Introduction#
If you need to optimize images, you’ve come to the right place. Did you know that you can save up to 92% on the size of your image files and all this without any loss of quality noticeable to the naked eye?
As developers, we must know the importance of optimizing the images that we use or that will be used by the users of our app.
- A smaller file size will make our website load faster.
- Google takes into account the loading speed of our website to position us, so it is better for SEO.
- If we allow our users to upload images to our website/api, we can save on bandwidth consumed both in the upload and in each download/view.
- As an additional advantage we will save storage space.
