Online Image Cropper

The Ultimate Guide to Image Cropping

The Adiminium Image Cropper is your digital scissor. Cropping is one of the most fundamental yet powerful editing techniques. It allows you to remove distracting backgrounds, improve composition, and focus the viewer's attention purely on the subject. This tool provides an intuitive drag-and-drop interface to slice your images perfectly.

Composition Rules

Professional photographers use cropping to adhere to the Rule of Thirds. Ideally, the subject's eyes or the horizon line should align with the grid lines. By cropping a loose shot tighter, you can turn a mediocre photo into a masterpiece.

Aspect Ratios Explained

The "Shape" of your image matters for where it will be displayed:

• Freeform: No rules. Drag the box any way you like. Good for custom website banners.
• Square (1:1): The classic Instagram and Profile Picture format. Perfect symmetry.
• Portrait (2:3 or 4:5): The standard for Social Media stories (TikTok, Reels, Pinterest). Fills the phone screen.
• Landscape (16:9): The standard for YouTube and TV screens. Cinematic look.
• Standard (4:3): The shape of old TVs and most digital camera sensors.

Step-by-Step Guide

1. Upload: Your image loads on the canvas.
2. Draw: Click and drag anywhere to create your selection box.
3. Refine:
   • Drag the Center to move the box.
   • Drag the Sides to expand/contract.
   • Select a Preset to force a specific shape.
4. Crop: Click the button. The area OUTSIDE the box is deleted permanently from the new file.

Technical Note

This crop is "Destructive" to the new file (pixels are removed), but "Non-Destructive" to your original file (which stays safe on your hard drive). The output resolution will match the pixel count of your selection. If you select a tiny area of a big photo, the resulting image will differ in resolution.
