How to Convert Images to WebP?

Image conversion to webp format

WebP is an image file format that can easily be converted to any other needed format such as PNG or JPEG using an online platform. Some of them are even for free to some extent.

Before we get into that, let’s take a closer look at the WebP format. What it is, its main characteristics, and its uses, among other relevant details you’d want to know before choosing the image file format you’ll use on your website. 

What is WebP File Format?

With the objective to replace the JPEG, PNG and GIF file formats, in 2010 Google developed the WebP format. This kind of format supports lossy and lossless compression as well as animation and transparency. 

Lossy compression is an irreversible type of compression, where data from the original file is discarded. This kind of method discards inexact approximations of data.

On the other hand, the lossless type of compression allows the original data to be reconstructed, without losing any of the original data.

When creating websites, speed and performance are essential aspects you need to consider if you want your site to rank as high quality. Image optimization has come to be the main factor to achieve both of those aspects. By reducing the file sizes through compression, it’ll be easier and faster for the site to load and that’s one of the main objectives when creating a website. 

Why To Use WebP Format?

As we mentioned before, images have an important role in the performance of a website. That being said, the reason why WebP is so significant is that it is a pixel-based format specifically created for online images, which supports lossy and lossless compression. 

This kind of format has a predictive coding method that only includes necessary data without jeopardizing the visual result of the image. This means that the image is small-sized and high quality at the same time. 

Which Web Browsers Natively Support WebP

When choosing to use WebP it’s important to know that it’s not a supported format for every web browser. However, the images on your site will not appear broken if they are set up properly.

The web browsers that currently do not support WebP image format are Google Chrome 4 to 21. With some of the latest versions of Chrome, the support of the WebP format is only partial. 

The Goggle Chrome version for Android supports WebP files from version 25.

Microsoft Edge supports these files from version 18. It’s not supported in Safari browser version 3.1 to 11.1 and Mozilla Firefox browser version 2 to 61.

These specifications include either lossy or lossless kind of compression of the files. If you’re planning to use WebP files on your website, it’s important for you to choose the right compression method.

Why did Google Release WebP as Open Source?

WebP is an open-source image format, which means that is it publicly accessible to be seen and modified by anyone who wants to use it. Upon its released, Google believes that an open-source format will encourage users to make suggestions and editions that in the end will benefit the characteristics of the image format. 

What is the Maximum size a WebP Image Can Be?

Measured in pixel dimensions, the maximum allowed for WebP image format is 16383 x 16383. 

One interesting fact about the size format of WebP files is that if you want to convert a JPG or PNG format to WebP, the resulting image can be larger than the original image without compromising its quality, due to the color spaces that WebP files support.

As previously mentioned, there are different online apps that will provide you with the necessary tools to convert WebP formats into JPEG, PNG or GIF depending on your preferences.
