Crop Image to Ratio trims your pictures from the center to a common shape such as square, 4:3, 16:9 or 9:16. It is perfect for profile photos, thumbnails and social media posts.
Crop images to the right shape
Social networks, online shops and websites each expect pictures in particular shapes. A profile photo is square, a video thumbnail is wide, and a story is tall. This tool crops your pictures from the centre to a common aspect ratio, so they fit perfectly without stretching. You can crop many images at once.
What is an aspect ratio?
An aspect ratio describes the relationship between width and height. A ratio of 1:1 is a perfect square. 4:3 is the classic ratio of older screens and many cameras. 3:2 is typical for photography prints. 16:9 is the wide format of modern video. 9:16 is the tall format used for phone stories and short videos. 3:4 is the portrait version of 4:3.
Which ratio for which purpose?
- 1:1 for profile pictures, product listings and many social posts.
- 4:3 and 3:2 for general photos, blog images and prints.
- 16:9 for video thumbnails, banners and presentation slides.
- 9:16 for stories, reels and vertical phone wallpapers.
- 3:4 for portrait photos and many e-commerce product pages.
How the cropping works
The tool finds the largest area of your picture that has the ratio you choose, centred in the image, and keeps only that part. The remaining edges are removed. No scaling is done, so the pixels in the cropped area keep their original quality. The file is saved in the same format as the original.
When centre cropping is enough
Centre cropping works well when the main subject is in the middle, as in portraits, products and logos. If your subject is near an edge, a centred crop may cut part of it off. In that case, rearrange the photo with a photo editor that lets you drag a crop box, or take the picture again with space around the subject.

Tips for better crops
- Take photos with some free space around the subject. It gives you freedom to crop to different ratios later.
- Crop first, then resize. Cropping a large image and shrinking it afterwards gives the sharpest result.
- Keep an original copy because cropping permanently removes the outer parts.
- For profile pictures, crop to 1:1 and then use the Round Image tool for a circular version.
Troubleshooting
The subject is cut off. The picture has the subject off-centre. Try a different ratio, or use an editor that supports manual crop selection.
The image became smaller. That is expected; part of the picture was removed to reach the ratio.
The format changed. The tool keeps PNG and WebP. Other pictures are saved as JPG.

A real-world example
Rabia sells handmade bags online. Her marketplace requires square product photos, but her camera takes 3:2 pictures. She selects all 30 photos, chooses 1:1 and the tool crops each from the centre. Because she placed each bag in the middle of the frame, every picture is ready in a minute instead of being edited one at a time.

More questions about this tool
Can I choose which part of the picture is kept?
This tool crops from the centre, which suits most portraits and products. If you need a different area, move the subject to the centre first or use an editor with a manual selection box.
Will cropping reduce the resolution?
The number of pixels becomes smaller because part of the picture is removed, but the pixels that remain are not changed.
