3. Use The Right File Format To Optimize

There are 4 main file formats used for saving images and graphics. These are:

  • PNG
  • JPG
  • GIF
  • SVG

Each format has different pros and cons and different uses. Which you choose will depend on different factors, such as if an image is a raster or a vector.

Pixel-based programs create raster images. You can also make them with either a camera or a scanner. They have a limited number of pixels, which means that they lose their sharpness and become pixelated when scaled too large. They should be saved as PNG, JPG or GIF files.

Vector images are specifically created with vector software. They can be scaled up infinitely without losing any quality. If you save vector files as SVG or GIF files you can size them up infinitely. If you save them as a JPG or PNG file, you lose that capability.


JPG is the most common raster file format for images. It has the smallest file size, is best for high quality photos, and is compatible across the web and devices. However, they lose quality when compressed too much and do not support transparent backgrounds.

They are best for still photos and photos without transparent or colored backgrounds.


PNG is a versatile and common raster format. It supports many colors, transparent backgrounds, and alpha channels. In fact, they can show over 16 million colors.

PNG can be compressed without losing as much quality as JPG. However, this format tends to have larger file sizes. It also does not support animation. This format is best for graphics with sharp edges, text graphics, icons, logos, and various other designs. PNG us best for graphics that need to be placed on non-white backgrounds.



GIF is the raster format for moving or animated images and messages. For example, the image above is a GIF. This format also supports transparent backgrounds.

With this format, the visual quality and size depend on the number of colors. More colors leads to a sharper image, but also a larger file size. You are also limited to 256 colors.


This vector format lets you have sharp graphics and control over the objects you post on the web. Vector programs like Adobe Illustrator and Inkscape create files in this format.

SVG allows you small file sizes, infinite sizing up of the image without quality loss, easy flexibility, and can be animated. Image quality and the number of colors and file size are interlinked. You are limited to 256 colors also. This is similar to the GIF format.

4. Export Multiple Sizes For High Pixel Density Displays

It’s no secret that mobile devices are taking over when it comes to viewing digital content. In fact, mobile surpassed desktop as the primary way people browse the web back in 2016.

Mobile devices actually have higher resolution screens than many desktop computers. Their HiDPL Retina or high density displays have over 200 pixels per inch (PPI) and the standard for most desktop computers is only 72 PPI.

If users access an image on their mobile devices made with PPI of a desktop computer in mind, it might not look crisp and professional.

You want to be sure to save out all of your pictures with the PPI of mobile devices in mind. You definitely need to impress both desktop and mobile users.

Ultimately, your copy and use of images need to work together in order to create a strong digital brand. Whether you use graphics or gifs, they need to show up clearly. This is incredibly important. It can shape the opinions people have of your digital brand.

When it comes to e-commerce, it can stop people from purchasing your products at all. If people cannot clearly see your products based on your images of them, they will be unlikely to buy them. You don’t want to alienate customers by forgetting to optimize visuals.

You don’t want images to be blurry, pixelated, distorted, or to show up incorrectly on mobile devices. This looks unprofessional and can also make potential customers and clients form a negative first impression. Instead, you always want your images to be crisp, clean, and clear on every device.
