How to use Crop Image
Crop images to any dimension with a drag-to-select interface — entirely in your browser. Set a fixed aspect ratio for social media formats (1:1 square, 16:9 widescreen, 4:5 portrait) or freehand crop to any custom region. Perfect for focusing on subjects, removing borders, and creating platform-optimized thumbnails.
- Upload your image by clicking or dragging it to the tool.
- Drag the crop handles to select the area you want to keep.
- Optionally select a fixed aspect ratio for consistent output dimensions.
- Preview the cropped result in the preview panel.
- Click "Crop & Download" to save the cropped image.

Aspect ratio presets and social media sizing
Fixed aspect ratio cropping ensures platform compliance without manual measurement. The 1:1 square is standard for Instagram feed posts, Facebook profile photos, and Twitter avatars. The 16:9 ratio matches YouTube thumbnails, website hero banners, and widescreen presentations. The 4:5 portrait ratio (0.8 aspect) maximizes vertical real estate in Instagram feeds on mobile. The 9:16 ratio is the standard for Instagram Stories, TikTok, and YouTube Shorts.
Rule of thirds and composition
The rule of thirds divides the frame into a 3×3 grid — placing the subject at one of the four intersection points creates a more dynamic and visually interesting composition than centering it. Enable the grid overlay in the crop tool to guide placement. For portrait photography, align the eyes with the top horizontal third-line. For landscape photos, place the horizon on either the upper or lower third-line, never through the center.
