How to Resize Images to Perfect Dimensions for Your Blog
Updated 2026-02-18Verified Private
Uploading a 4000px photo and then showing it at 400px on your blog is a huge performance mistake. You're making users download 10x more data than they need.
Why is this needed?
Physical resizing ensures the browser does zero work to scale the image, resulting in smoother scrolling and faster rendering.
!Step-by-Step Instructions
1
Upload and Set Width
Enter your target width in pixels (e.g., 800px).
2
Maintain Aspect Ratio
Keep the 'Lock' icon on to ensure your photo doesn't look stretched or squashed.
3
Process and Download
Your new, perfectly sized image is ready in milliseconds.
Pro Tips
- •Modern high-res (Retina) screens look best if you resize to 2x the display width (e.g., 1600px for an 800px slot).
- •Always name your resized files with keywords for better Image SEO.
Frequently Asked Questions
Can I enlarge a small photo?
You can, but it will look blurry. Resizing works best when making large small photos smaller.
Does it affect the file format?
No, we preserve your original format (JPG/PNG/WebP) unless you choose to change it.
