There are many image file formats that exist; among the most popular are: .GIF (Graphics Interchange Format), .PNG (Portable Network Graphics), .JPEG (Joint Photographic Experts Group), and .BMP (bitmap). Which format to use is a very popular topic for discussion/debate. However, most can agree on the fact that it depends on your intended use. For instance, the PNG format is optimal for displaying site icons and screenshots with markups. However, JPEG is optimized for maintaining the highest quality of image balanced with file size/compression. Therefore photos without text/markup would display better as the JPEG format.
cPanel features an image format converter to help you create images that are optimized to improve your website’s speed. In this guide you can learn how to convert image file formats (JPEG to PNG) stored in your cPanel account files using cPanel.
Under the Files subheader, click on the Images icon.
Click on the Converter link.
Navigate to the directory where your images (that you would like to create thumbnails for) are stored.
NOTE: You must click on the folder icon(s) to navigate through the directories and click on the folder name to make your selection.
Once a selection is made, cPanel will allow you to specify the file format which you want to convert your images to. Select Portable Network Graphics (png) from the drop-down menu.
Click on the Convert button.
The page will reload once the images have all been converted and display a message similar to the following:
“Your images have been converted.”
Congratulations! Now you know how to convert image file formats using cPanel.
