Cropping vs. Resizing: What's the Difference?
While often used interchangeably, cropping and resizing are two very different operations.
- Cropping removes parts of the image to change the composition or aspect ratio. It deletes pixels.
- Resizing changes the actual dimensions of the image. It scales pixels up or down.
Best Practices for Cropping
When cropping, always keep the final destination in mind. For Instagram, a 1:1 (Square) or 4:5 (Portrait) ratio is best. For YouTube thumbnails, aim for 16:9.
Rule of Thirds: Imagine a grid dividing your image into nine equal parts. Try to place your subject along these lines or at their intersections for a more balanced composition.
How to Resize Without Losing Quality
Resizing an image down (making it smaller) usually retains quality. However, resizing up (making it larger) can result in pixelation.
Onyx uses advanced interpolation algorithms to ensure that your images remain as sharp as possible, even when making slight adjustments to size.
