Resize image for X (Twitter) Header (1500×500)
X (formerly Twitter) headers are 1500×500 pixels — a wide 3:1 banner that stretches across the top of your profile. Matching this exact size avoids cropping and looks crisp on every screen.
Your files never leave your device. No upload. No sign-up.

X (Twitter) tip
On mobile, your profile picture overlaps the bottom-left of the header. Keep critical text and logos in the upper-right two-thirds of the image.
Frequently asked questions
- Why such a wide aspect ratio?
- Headers are designed to fill the full width of the desktop profile, which is much wider than tall. 3:1 lets X show the full image on desktop with a clean mobile crop.
- Is there a file-size limit?
- X allows up to 5 MB for headers. A 1500×500 JPG at 85% quality stays comfortably under.
- Can I use a transparent PNG?
- Yes, but X will composite it onto a white background. JPG is usually the better choice for headers.
