Image Optimization

CodeNull applies automatic optimization to uploaded images to ensure fast loading and optimal display:

The system provides detailed feedback on optimization results:

• Original vs. optimized file size
• Quality comparison
• Generated formats and variants
• Performance improvement metrics
• Browser compatibility information

Optimization Settings

Control the optimization process with detailed settings:

Global Optimization Settings

• Default Quality: Base quality level for all uploads (75-85% recommended)
• Preferred Formats: Order of format preference (WebP, AVIF, original)
• Size Limits: Maximum dimensions for uploaded images
• Responsive Breakpoints: Define size variants for different screen sizes
• Strip Metadata: Choose which metadata to preserve or remove
• Compression Strategy: Balance between speed and efficiency

Best Practices for Image Uploads

Start with high-quality source images. While CodeNull can optimize any image, better source files will yield better results.

• Prepare images before upload: Crop and adjust as needed
• Use descriptive filenames: Name files clearly to improve organization
• Always add alt text: Ensure accessibility for all users
• Choose the right format:
  • Photos: JPEG/WebP
  • Graphics with transparency: PNG/WebP
  • Icons and simple illustrations: SVG
• Organize as you upload: Assign to appropriate folders immediately
• Tag thoroughly: Add relevant tags to improve searchability

Troubleshooting

Upload Failures

• Check file size limits (current max: 10MB per file)
• Verify supported file formats
• Check network connection
• Ensure you have sufficient storage space
• Verify that the filename doesn’t contain special characters

Optimization Issues

• For blurry images, try increasing the quality setting
• If file size is larger after optimization, try a different format
• For color issues, check if the image uses a non-standard color profile
• SVG optimization issues may be due to complex paths or embedded images

Performance Concerns

• For slow uploads, try smaller batches
• If processing is slow, disable AI features for non-critical uploads
• Consider scheduling large uploads during off-peak times
• Use the priority setting for urgent images
