Images are a very important tool that allows us to tell stories. When it comes to a website or even more e-commerce, images have the important role of creating a mood, and basically, to make a website far more attractive. That’s enough reasons to invest time to optimize our images, right?
When we talk about image optimization for a website, we can think about it in three ways:
- Make images look good and at high-Quality.
- Make images load fast.
- Build images easy for search engines to index.
An image with the right composition and colors, showing the product, could sell infinitely more than a clever or long description. The well-known phrase “a picture paints thousands of words” describes the meaning and the importance of images in the XXI century, or even more, in the online shop world that we are used to living. If you are an e-commerce owner, the advantages of images become essential: you need to show what you’re selling!
When it comes to images on the website, our goal is to achieve a balance between visual appearance, format, and size. Of course, we don’t only want those images to look sharp and crisp, but you need it to load quickly.
Start managing High-Quality Images
Using photos taken by a professional photographer, or even yourself (or your staff) is great. If you haven’t, there are high-quality free photo stocks, that you can download and use for free*. We recommend Unsplash, Pexels, and Pixabay. But at the end of this article, I give you a list with more free photo stocks to use it for free.
The importance of starting with images larger than 1MB is that you can resize with free tools such as resizeimages.com and compress them without losing quality and maintaining the original colors. Starting with a smaller image and enlarging it doesn’t usually work very well (it will pixelate).
If you need to build graphics rather than images, or photos with front overlays, there are other free tools that will help you, such as Canva.
Use the correct format and size to load faster
Now, you invested a lot of time shooting, thinking and composing your images. But, your Images have large file size and each image you upload to your website will impact the website’s load time.
The most commons formats we are used to managing are JPG (JPEG) or PNG files.
- JPGs are usually the best format for photographs and the most known format.
- Graphics are usually saved as a PNG. This is because a PNG is a higher quality and larger file that JPG. This format, also support transparent backgrounds commonly used for logos.
Moreover, we need to know what are the differences and meaning of: file size, image size and resolution.
File size is associated with the number of bytes. A 10MB photo is too large; a 250KB photo is much more reasonable. If your file size is too big, it’s an indicator that either your image dimensions are too large or the resolution is too high. That means, we need to optimize them.
The Image size is related to pixels. The more pixels, the more quality.
And the Resolution is measured in dots per inch (DPI). Most computer monitors, display images at 72 dpi or 92 dpi. The more dpi, the more your website will slow down.
If your photograph or image is too large, here is what to do:
The huge monster of Google created a new image format, specially designed to help with page speed and combines the best of PNG and JPG. Ladies and gentlemen, we introduce you to WebP!
