4320.0904 Exporting and Optimizing for Various Platforms
High-quality food photos are essential for showcasing dishes professionally, whether on social media, websites, or print materials. Proper exporting and optimization ensure your images look great and meet specific platform requirements. Here’s a clear, step-by-step guide:
General Exporting Principles
A. File Formats
- JPEG: Ideal for web and social media, balancing small file size and good quality.
- PNG: For images needing transparency, like logos.
- TIFF: Best for print; retains maximum detail.
- WEBP: A modern web format offering excellent quality with smaller file sizes.
B. Color Profiles
- sRGB: Standard for web and social media to ensure consistent colors.
- Adobe RGB: Preferred for print, offering a wider range of colors.
C. Resolution
- Web and Social Media: 72 dpi is sufficient for screens.
- Print: Use 300 dpi for sharp, high-quality prints.
D. File Size
- Web and Social Media: Keep file sizes under 1 MB for quick loading.
- Compression: For JPEG, use 70%-85% quality to balance size and detail.
Resizing Images for Social Media
Each platform has specific requirements to ensure your images display properly:
- Square Post: 1080×1080 px (1:1 ratio).
- Portrait Post: 1080×1350 px (4:5 ratio).
- Landscape Post: 1080×566 px (16:9 ratio).
- Stories/Reels: 1080×1920 px (9:16 ratio).
- Shared Image: 1200×630 px.
- Cover Photo: 820×312 px (desktop) or 640×360 px (mobile).
- Standard Pin: 1000×1500 px (2:3 ratio).
- Shared Image: 1200×675 px.
- Header Image: 1500×500 px.
- Post Image: 1200×627 px.
- Banner Image: 1128×376 px.
Resizing Images for Websites
A. Common Dimensions
- Hero Images (full-width headers): 1920×1080 px.
- Content Images: 1200×800 px.
- Thumbnails: 150×150 px or 300×300 px.
B. Performance Optimization
- Compress images to under 500 KB to ensure fast loading.
- Use lazy loading so images load only when visible on the screen.
C. Formats
- JPEG: Use for standard images.
- WEBP: For smaller, faster-loading images with minimal quality loss.
D. SEO Tips
- Rename files descriptively (e.g., pasta-dish.jpg) for better search ranking.
- Add alt text for accessibility and SEO (e.g., “Bowl of creamy pasta with Parmesan cheese”).
Resizing Images for Print
A. Print Dimensions
Convert inches to pixels using 300 dpi:
- 4×6 inches: 1200×1800 px.
- 8×10 inches: 2400×3000 px.
- 11×14 inches: 3300×4200 px.
B. Bleed
- Add 0.125 inches (3 mm) around the edges to prevent important details from being trimmed during printing.
C. File Format
- Save as TIFF or high-resolution JPEG for professional print quality.
Balancing File Size and Quality
A. Compression Tools
- Use tools like TinyPNG or JPEGmini to reduce file sizes while maintaining quality.
- In Photoshop, use Export As or Save for Web to adjust quality settings.
B. Test Output
- Open compressed images on different devices to ensure clarity and color consistency.
Automating Workflow
A. Batch Processing
- Use Adobe Lightroom or Photoshop to resize and export multiple images at once.
B. Presets
- Create platform-specific presets for Instagram, websites, or print to save time and ensure consistency.
C. Versioning
- Save separate versions for web, social media, and print to avoid re-editing.
