How To Check Your Speed and Images
Many people just starting out don’t realize how important website speed is.
Often they think their website is ok and don’t test it. Because browsers hold a cached copy, they don’t experience it like a new person visting the site for the first time.
However, a normal user who is visiting your website for the first time may not have the same experience.
In fact, because where the site is hosted matters, people in different Countries will have totally different load times.
So test your website using tools like Pingdom.
How To Optimize Different Types of Images
There are two main file types you’ll want to optimize for the web: png and jpg.
WORKING WITH JPGS
JPGs (also known as JPEGs) are the most popular file type for images on the web because they are generally smaller than png files. JPGs are ideal for photographs, or images with color, shadows, gradients, or patterns. JPGs have a huge color pallet and make these types of images look great.
Broadly most people save jpg in either high, mid or low quality. High quality delivers the full impact of the image but has a much bigger file size. Low-quality images start to become pixelated and look more grainy. So in most cases, you want to choose a mid to low point for use on the web.
Obviously the size of the image in pixels matters. We will discuss this in a moment.
WORKING WITH PNGS
The main difference between PNGs and JPEG’s is that PNG files can be transparent.
PNGs are another common file format used on websites.
PNG-24 provides a much higher quality image, however, the size of an image file becomes large.
This is where good lossless optimization tools come in.
How To Optimize Different Types of Images
Use PNGs for logos, icons and featured images because they are high quality, and offer transparency.
Use jpgs for most other images on your site.
