How to Create Blog Headers at imgresizr.com
Upload your source image or graphic to imgresizr.com. For maximum compatibility, target 1200×628px — this is the standard Open Graph image size used by Facebook, Twitter, and LinkedIn when your blog post is shared. Use the Crop tool to set this ratio (approximately 1.91:1). Use the Enhance tool to boost colour vibrancy — blog header images on social media compete with hundreds of other posts, so vivid, eye-catching imagery performs better. Add your blog post headline using the Caption or Text tool for social sharing versions. Compress to under 500KB for fast page load speed — slow-loading featured images hurt both SEO and reader experience.
Blog Header Image Tips
- Human faces and people in action outperform objects and abstract imagery in click rates
- Contrast between the image and text is critical — dark images with white text, or bright images with dark text
- Create a consistent visual style across all your blog headers for brand recognition
- Always compress before uploading — page speed is a Google ranking factor
- Use your blog's primary keyword in the image filename for a small SEO boost
