Part 4. FAQs about How to Crop a Picture

Does cropping photos reduce quality?

Yes. When you crop an image, you are essentially losing specific pixels. Those pixels are tiny building blocks that make up your photo. The more you remove, the more you are chiseling away from the overall quality. Nevertheless, a few photo editors can enhance image quality during the process.

Is it better to zoom in or crop a photo?

Zooming is changing the length of your photo. It gives you more details of the photo, but won't modify the dimensions. Cropping an image means trimming parts of the image away to make it smaller. However, it won't show you more details. Whether you zoom or crop a photo depends on your purpose.

Will cropping affect JPEG?

Yes, image cropping can affect the resolution and quality of a digital photo. When you crop a photo, you are effectively reducing its pixel dimensions. That leads to a decrease in the overall image quality if significant portions are removed.
