How it works
X sizes
The tool knows 5 places on X where you upload a picture, and frames your photo for each one:
Profile picture: 400 × 400 px
Header: 1,500 × 500 px
Post image (16:9): 1,600 × 900 px
Square post image: 1,080 × 1,080 px
Link card: 1,200 × 628 px
Framing and saving
The photo is scaled up just enough to cover the frame, and the part you see is what is saved. Drag the picture, nudge it with the arrow keys, zoom in with the slider, or rotate it a quarter turn. In the case of profile picture, the output is 400 × 400 px.
Choose PNG for a lossless file or JPEG for a smaller one, then download one size, or every size for the platform in a single zip.
