Crop an image to an exact aspect ratio

Choose the aspect ratio (square, portrait, widescreen or one you type in), move the photo to decide what stays in the frame and download the crop at its full resolution.

How it works

  1. Choose the photo

    Tap the box or drop in the image you want to crop.

  2. Pick the ratio and framing

    Select 1:1, 4:5, 16:9, 9:16 or another ratio, and drag the photo or use the zoom to adjust the framing.

  3. Download the crop

    Download the cropped image. It keeps as much of the original photo's resolution as possible.

Which aspect ratio to use

1:1 is the classic square of profile pictures and product catalogs. 4:5 is the portrait format that takes up the most space in the Instagram feed. 9:16 is the full phone screen: Stories, Reels, TikTok and Shorts. 16:9 is the format for video and YouTube thumbnails, and 3:2 is the one used by cameras and 4×6 in (10×15 cm) prints.

Cropping is not resizing

Cropping removes part of the image to change its shape; resizing changes the number of pixels without removing anything. If you need a specific size in pixels after cropping, run the result through the resize tool, or use the social media sizes tool, which does both at once.

Frequently asked questions

How do I crop a photo into a square?

Upload the photo, choose the 1:1 ratio and drag the image to decide which part stays inside the square. Then download the crop.

Does cropping reduce a photo's quality?

No. The crop keeps the original pixels of the area you choose, without enlarging them or compressing them further. You only lose what falls outside the frame.

What aspect ratio should I use for Instagram?

4:5 for portrait feed posts, 1:1 for square ones and 9:16 for Stories and Reels. The 4:5 ratio is the one that fills the most screen in the feed.

Can I use a custom aspect ratio?

Yes. Choose “Custom” and type the width and height of the ratio, for example 21 and 9 for an ultrawide format.

Does it work on a phone?

Yes. You can move the photo with one finger and zoom with the zoom control or by pinching with two fingers.

Is the image uploaded to a server?

No. The crop happens in your browser and the photo doesn't leave your device.
