How to improve image quality

By default, WordPress compresses and resizes your images so that your site loads more quickly. This process degrades image quality. Here are several tips to improve image quality:

• Don’t use blurry or pixelated images. Instead, capture or source high quality and high resolution photographs.
• When possible, resize your images to the required dimensions before uploading them to WordPress. You can find a list of image dimensions at the bottom of most theme tutorials.
• Regardless of file format, use the RGB (screen) color space. The CMYK color space is for print media.
• Increase WordPress’ default JPEG image compression limit with the SimpleJPEGQuality plugin.
• Alter the sharpness of resized images with the Sharpen Resized Images plugin.
