Where is the 16:9 crop made?

In your browser. When you click Crop & download, the Canvas API draws the selected area onto a new canvas in this tab and encodes it there. Our servers are not involved at any point.

What image formats are supported?

You can upload JPEG, PNG, WebP, GIF, and most other common image formats. The cropped image downloads as JPEG or PNG.

Can I crop to an exact pixel size?

The readout under the image shows the exact width and height in pixels of the area that will be exported. Drag the box and its corner handles, or focus the box and use Shift plus the arrow keys, until it shows the size you need. On a large image each step covers a few pixels, so for a fixed size, crop slightly larger and then use the resize tool.

Does cropping reduce image quality?

Cropping itself changes nothing inside the box. PNG downloads keep those pixels exactly; JPEG downloads are re-encoded at quality 0.92, which adds a little compression in exchange for a smaller file.

What size should a YouTube thumbnail be?

YouTube recommends 1280 x 720 pixels, which is 16:9. Crop to 16:9 here, then scale the result to exactly 1280 x 720 with the resize tool if your crop is larger.

Crop image online to 16:9, 4:3 or 9:16

Crop an image to the shape the place it is going needs: 16:9 for video thumbnails and widescreen slides, 4:3 for classic presentation slides, or 9:16 for phone stories and vertical video. The crop box starts at 16:9, so pick another ratio if you need one, drag the box over the part you want to keep, and download it as JPEG or PNG. All processing runs in your browser.

How it works

The tool reads your image into browser memory and displays it in an interactive crop preview. Drag the crop box to reposition it, or pull the corner handles to resize. When you click Crop & download, the Canvas API draws the selected region to an offscreen canvas in your browser tab and exports it as a file.

Processing runs in your browser

The Canvas API processes the crop operation locally, and the resulting file is downloaded directly to your device. Our servers are not involved at any point.
