    Drop the image on the page, choose it from your device or Google Drive, or paste a direct download link. One image per run.

特長

Crop image trims a photo to the frame a social network or website expects, such as a square 1:1 avatar or a vertical 9:16 story. Pick a preset ratio to keep the center of the picture, or switch to Custom and enter X, Y, width and height when you need an exact area.

  • Six frame choices: 1:1, 4:3, 3:4, 16:9, 9:16 and a custom pixel area.
  • Preset ratios always keep the center of the image, ideal for portraits and product shots.
  • The original format is kept: a JPG stays a JPG and a PNG keeps its transparency.
  • Accepts JPG, PNG, WebP, GIF, BMP, TIFF and AVIF up to 100 MB.
  • Results get a “-cat-khung” suffix, e.g. “avatar-cat-khung.png”.

よくある質問

Does cropping reduce image quality?

The part you keep is not scaled down. The image only gets smaller in dimensions because the area outside the frame is removed.

How do I find the X and Y values for a custom crop?

X is the distance from the left edge and Y from the top edge, both in pixels. Check positions in any image viewer on your device before typing them in.

Can I make a square crop that is not centered?

Yes. Choose Custom, enter the same width and height, then set X and Y to the area you want to keep.

Can I crop several images at once?

This tool crops one image at a time so you stay in control of the frame. To resize up to 20 images in one go, use Resize image.
