Images that are added to a website need to be optimized for many reasons. The use of many unique images is a great way to grab the attention of a visitor. However, images that are too big lead to web pages which can be extremely large. Web pages that are large can take longer to load and can be a reason for decreased search engine rankings.
Every image that is displayed on a web page needs to be downloaded to a visitor’s computer. This is an aspect that needs to be kept in mind when adding any images to a web site. The need to use SEO is important for search engine rankings and will involve page load times. A site that has heavy graphics needs images that have been optimized. Review a few methods that can be used to optimize images.
There are many types of file formats that can be used for images. The most common formats used on a web page include JPG and PNG. Another format that may be used is a GIF.
JPG – This image format is commonly used for photographs. Compression is used to reduce the size of the file.
PNG – One common type of image using this format is a screen shot. Most of the buttons and icons on a website are typically a PNG file. The quality of the images are generally higher with this format. The use of this file format often means file sizes are often higher.
GIF – Low-quality images are more likely to be a GIF file. This format is also common for any files that are animated.
Optimize Before Upload
Optimizing images is difficult once they have been uploaded to the Internet. This is why the process of optimization needs to be done prior to any uploading. One option is the thumbnail feature that is found in common CMS and Blog platform. This feature is in the admin area under the option for settings/media. A user is able to set the size of thumbnail images. There is an option for 150 x 150, 300 x 200, and 600 x 600.
Any large images that have already been uploaded to a website can have a thumbnail with a link to the full-size image. This is the option typically used by many bloggers. However, this is not really the best option to handle website images.
The best way to optimize images before uploading is to resize in an image program. A user can change the size of an image by using Photoshop or any other image editing software. Decreasing any image is a great way to improve the loading time of any web page.
Properly optimizing the images on a site cannot be overstated. The time to load a web page is significantly improved and bandwidth is reduced. The quick loading of web pages will typically result in the improvement in search engine results. One thing to keep in mind when resizing an image is not to get any too small as this can affect the overall quality seen on the screen.
