Platform
Image type

A 16:9 frame often used for an image attached to a post. Output: 1600 × 900. These sizes are common defaults, not an official platform specification.

Placement

Crop covers the frame. Drag the preview to choose which part remains.

Target dimensions

The header preset is 1500 × 500. X can crop a header differently across devices, so do not place text at the extreme top or bottom.

How cropping works

The profile preset is a 400 × 400 square. This tool does not post to X.

Drag the preview when Crop is selected. Reset crop returns to a centered view. The downloaded file uses the pixel size shown for the preset.

Privacy

The image is decoded and resized in your browser. It is not uploaded to SizeUply and it is not sent to the social network.
