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
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
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
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
