Open the Image Resizer
Go to the Resize tool — runs entirely in your browser, no file upload to a server.
Upload your header image
Drop your photo, gradient, or branded graphic onto the upload zone. JPG works well for photos; PNG for graphics with text or flat colours.
Click the 'Twitter / X Header' preset
The Twitter Header (1500×500) preset is in the social media presets panel. One click applies the 3:1 dimensions.
Or enter dimensions manually
Turn off 'Maintain aspect ratio'. Set Width to 1500 and Height to 500.
Keep content in the safe zone
X's mobile layout shows a shorter crop of the header. Keep text, logos, and key visuals in the central 1500×360px area (top 360px), and away from the bottom-left 200×200px where your profile photo overlaps.
