Frequently Asked Questions

Can I set a crop ratio?

Various aspect ratios are supported including Free, 1:1 (square), 4:3, 3:2, 16:9, 9:16, 3:4, and 2:3. Click a ratio button to drag and select an area locked to that ratio. In free mode, you can set the crop area to any size you want.

Is the original image preserved after cropping?

Yes, the original image is not changed. This tool operates only in the browser and does not modify the original file. When you download the cropped result, it is saved as a separate new file, and the original image remains intact.

What image formats are supported?

You can upload and crop images in JPG, PNG, WebP, and GIF formats. The cropped result is saved in PNG format and downloaded without quality loss. For GIF files, animation is not preserved — only the first frame is processed.

Does cropping change the resolution?

Cropping reduces the resolution (pixel count) by the size of the selected area. For example, if you crop a 500×400 area from a 1000×800 image, the result will be 500×400 pixels. You can check the display size and actual pixel size in the crop info display.

How to Use Image Cropping

Image cropping is an essential task for keeping only the desired portion of a photo or fitting an image to a specific platform's required ratio. Images cropped to the correct ratio and composition give a more professional impression across various uses such as social media profiles, blog thumbnails, and product images.

Recommended Image Ratio Guide by Platform

Instagram profile photos are recommended at 1:1 square, feed images at 1:1 or 4:5, and stories at 9:16. YouTube thumbnails are typically 16:9, and blog featured images are commonly 16:9 or 4:3. For Naver Blog and Kakao Channel cover images, it is best to crop to the specific ratio required by each platform.

Cropping Tips for Good Composition

This tool displays a rule of thirds grid over the crop area. Placing the main subject near the intersection points of the grid lines creates a more dynamic and balanced photo. Boldly cutting out unnecessary backgrounds to focus on the subject increases the impact of the photo.
