Low-resolution images happen when files are served at smaller dimensions or compressed too much. The solution is to deliver properly sized, optimized images in modern formats that maintain clarity.
Common Causes
- Incorrect scaling: Resizing in HTML or CSS instead of serving the right dimensions.
- Excessive compression: Over-optimized files lose detail.
- Wrong format: Using JPEG for graphics that need PNG or SVG.
- Responsive design issues: Mobile layouts pulling thumbnails instead of full-quality images.
How to Fix
- Serve correct dimensions: Export images at the size they’ll be displayed.
- Use modern formats: WebP or AVIF provide high quality at smaller file sizes.
- Implement srcset: Allow browsers to choose the right resolution for each device.
- Check compression settings: Balance file size with clarity.
- Use CDNs: Many content delivery networks automatically optimize images per device.
Best Practices
- Preview images on multiple devices before publishing.
- Avoid stretching small images to fit large containers.
- Use SVG graphics for logos and icons to ensure sharpness at any resolution.
