AI Smart Resize — Perfect Framing Without Cropping
Tired of manually cropping images for different platforms? WeryAI's Smart Resizer automatically detects and locks onto your main subject, then uses AI-powered creative fill to expand backgrounds, perfectly fitting any aspect ratio while keeping every image visually centered.

Key Features
Smart Subject Detection — Center Stage, Always
No matter which ratio you choose, our AI precisely identifies and locks onto the core subject (people, products, etc.). When resizing, it ensures your subject stays in the optimal composition position—never accidentally cropped.
AI Creative Fill — Smart Background Extension
This is real magic! When converting landscape to portrait, AI doesn't brutally stretch. Instead, it intelligently analyzes the original background's texture and elements, creatively "painting" the missing top/bottom sections for seamless natural extension.
Golden Ratio Presets — One-Click Multi-Platform
We've preset all mainstream platform golden ratios. Whether it's 16:9 for YouTube covers, 9:16 for TikTok/Shorts, or 1:1 for Instagram squares, one tap gets you perfectly fitted images.

Lightning Fast, Lossless Quality
Advanced cloud processing ensures ultra-fast resizing. All operations maintain original quality, keeping your images crisp and sharp at any size.
