When to Crop vs. Resize

Cropping removes parts of an image to focus on a specific area — it changes the composition. Resizing scales the entire image up or down without removing any content. Use cropping when you want to eliminate unwanted background or reframe a subject. Use resizing when you need to fit the whole image into specific pixel dimensions.

Tips for Better Crops

Rule of thirds: Place your subject along the intersecting lines of a 3x3 grid for a more dynamic and visually appealing composition.
Leave breathing room: Don't crop too tightly around faces or objects — leave some space around the edges for a natural look.
Match platform requirements: Each social media platform has preferred aspect ratios. Using the right one ensures your image displays fully without auto-cropping.
