Resize Image to 1500×500 (X / Twitter Header)

1500×500 is the 3:1 header banner that runs across the top of an X (Twitter) profile — the wide strip behind your avatar and bio. Two things routinely wreck it: the circular profile photo punches into the lower-left corner, and X shortens the visible height of the banner depending on the viewport, so tall designs get clipped top and bottom. Sizing to exactly 1500×500 and keeping content in the centre band handles both. This tool crops your banner to that frame on your device, so a header you're still tweaking is never uploaded to a web editor.

Good to know

Outputs exactly 1500 × 500 pixels — X (Twitter)'s recommended 3:1 profile header size.

Keep your profile picture's corner clear: the circular avatar overlaps the lower-left of the header.

X trims the header's height on some layouts, so keep key text in the vertical middle, not near the top or bottom edge.

"Cover" fit fills the wide 3:1 banner and trims overflow, so there are no side gaps.

Export stays well under X's 5 MB header image limit at normal JPEG quality.

Runs entirely in your browser — no upload, no account, nothing stored.

Frequently Asked Questions

What size is an X (Twitter) header image? ▼

X recommends a 1500×500 pixel header, a 3:1 ratio, with a 5 MB maximum file size for JPEG or PNG. Supplying the banner at that exact size keeps it sharp and avoids X rescaling it.

Where does the profile photo cover the header? ▼

Your circular avatar sits over the lower-left area of the 1500×500 banner. Keep logos, faces and text out of that corner so the profile picture doesn't hide them. Centring or right-weighting your key elements is the safe approach.

Why does the top and bottom of my header get cut off? ▼

X shows a shorter slice of the 3:1 banner on some screens and layouts, so a design that reaches the top or bottom edge can look clipped. Keeping important content within the middle vertical band of the 1500×500 frame keeps it visible everywhere.

Is my header uploaded to resize it? ▼

No. The resize runs on a canvas in your browser, so your banner never leaves your device.
