Frequently Asked Questions
How does the crop selection work?
Simply drag on the image to define a crop area. The selection shows the exact output dimensions in pixels. Choose a preset aspect ratio to constrain the shape, or use Freeform for any proportion.
What aspect ratios are available?
We offer freeform cropping plus presets: 1:1 (square), 4:3, 16:9, and 3:2. These cover most common use cases for social media, web, and print.
Does cropping reduce image quality?
No! Cropping simply removes the unwanted area and keeps the original quality of the selected region.
Can I crop images for social media profiles?
Yes! Use the 1:1 square preset for Instagram and profile pictures, 16:9 for YouTube thumbnails and cover photos, or 4:3 for standard social media posts.
