There are several effective ways to optimize images in WordPress:
- Use Smush plugin for automatic optimization during upload
- Resize images to the exact dimensions needed for your theme
- Convert images to appropriate formats (JPEG for photographs, PNG for graphics with transparency)
- Use modern formats like WebP when possible
For best results, optimize images before uploading by using image editing software to reduce file size while maintaining quality. The Smush plugin can also bulk optimize existing images and automatically resize oversized images during upload.
