Smart Resizer Pro Guide: Resize Images for Social Media
Every platform needs a different image size. Smart Resizer Pro helps you resize one image for YouTube, Instagram, Facebook, LinkedIn, websites, and documents while keeping the subject framed correctly.
What Smart Resizer Pro includes
The tool includes ready presets for social platforms, custom width and height inputs, resize modes like Smart Fit, Smart Fill, Crop, and Stretch, plus background options such as white, black, transparent, blurred, or custom color.
Best resize modes
- Smart Fit keeps the full image visible inside the selected size.
- Smart Fill fills the canvas with a blurred background and centered main image.
- Crop fills the frame by cutting extra edges.
- Stretch should be used only when distortion is acceptable.
Common output sizes
Use 1280x720 for YouTube thumbnails, 1080x1080 for Instagram posts, 1080x1920 for stories or shorts, 1200x630 for Facebook posts, and 1584x396 for LinkedIn banners.
