Crop images to a portrait 3:4 frame
The 3:4 aspect ratio is a standard vertical format used in photography and digital media. It is the default portrait ratio for many smartphones and cameras, making it a familiar shape for portrait shots, wallpapers, and social graphics.
This tool allows you to crop images to 3:4 instantly in your browser, maintaining full control over the final framing.
Everything runs locally on your device, ensuring maximum speed and complete privacy.
Why the 3:4 format is standard
The 3:4 ratio is widely used because it mirrors the dimensions of standard camera sensors when turned vertically. It is narrower than a square but wider than 9:16, offering a balanced portrait layout.
It is commonly used for:
- Smartphone wallpapers and home screens
- Portrait photography and portfolio headshots
- Pinterest pins and vertical graphics
- Blog illustrations and headers
- Product showcase displays
