Image Optimization Best Practices
- Format: Use PNG for graphics with text or transparency. Use JPEG for photos. WebP offers the best compression for both.
- File size: Keep images under 5MB. Compress with tools like TinyPNG or Squoosh before uploading.
- Safe zones: Keep important content (text, faces) away from edges. Platforms crop differently on mobile vs desktop.
- Text on images: Keep text to less than 20% of the image area for best reach on Facebook and Instagram.
- Consistency: Use the same dimensions across a content series for a professional, cohesive feed appearance.
Pro tip: Use Capcher to capture social media posts as perfectly sized images. Capcher automatically generates images optimized for sharing across platforms — no manual resizing needed.
