A website with a lot of photos takes a long time to load. A long loading time will shorten the time visitors stay on your website. Compressed images make your page speed way faster. Using a developer API is a quick solution to compress a lot of photos in no time. But what is an API and how can you compress images with it?
What is an API?
An API, also known as an Application Programming Interface, connects different devices and applications with each other. It’s a software intermediary that ensures that two applications can interact. You could say that one application (the messenger) makes a request to another application (a provider) and then feeds back the response.
You probably use an API more often than you think. Let’s say, you want to book a flight and you want to compare different airlines. In most cases, you will use a travel service website to do the comparison, instead of visiting each individual airline website. This travel service website interacts with multiple airline APIs to get the information you are asking for. After you type in your preferences, the travel agency website will request this information via the airlines’ APIs. After receiving the API call, the airline will respond back with the available options. Now the travel agency website will collect the information and present the different options available that meet your search criteria.
An API key
For some companies, it’s important to have insight into the API use of certain users. This is done with an API key that users need to implement in their website’s code. It’s an unique code that allows the API to identify the calling user or program. In the given example, there are probably many travel agencies using the Airline’s API. Each of these agencies has an API key that is required when making the API calls. This way the airline can know which agency has made a specific booking or even find out what kind of searches are done most often by a certain agency.
API for image optimization
For image optimization there are also APIs available that can simply connect an image compression service to your website. This connection makes compressing the pictures on your website possible. For example, you can have your images automatically compressed during upload. You can upload them to a service via the API. Once it is compressed, you then can use the API to retrieve the optimized image and replace the original image. For most image optimization services an API key is needed, so the provider can keep track of how many files you have compressed.
Why compressing images with an API?
Instead of manually uploading all your images within an online compression tool, an API allows you to compress the files after uploading them on the website. The process is faster and saves you a lot of work. Besides, most companies offer extra features within the API service, for example resizing the photos. The list of features will be unique to each provider.
An API for image compression can be interesting for many types of users. When you have a lot of photos on your website or often upload new ones, an API can be extremely helpful. If you for example have a webshop with an always changing assortment, it would save a lot of time to optimize your images automatically via an API. Besides, you can enjoy the extra features it mostly offers.
