Open Resize Image for Twitter HeaderWhat the X header really displays
The API-compliant resolution is 1500×500. Desktop shows the centre trim; mobile compresses it. Resizing to the official size and keeping your logos near the middle avoids cut-offs.
Resize to 1500×500 in seconds
- Open the Resize Image tool.
- Enter 1500×500.
- Choose center-crop and position important content centrally.
- Download and upload in X settings.
Brand headers, privately
Marketing mock-ups and unreleased brand banners stay yours: the resize runs in your browser, so no agency, no client and no competitor ever sees a draft in a cloud inbox.
Designing a header that survives every crop
The 1500x500 canvas is only the upload size. On desktop the profile picture and your handle overlap the lower-left corner, on mobile the header is cropped tighter horizontally, and the banner appears again behind your posts. Design rule that never fails: keep the important text inside a centered safe area of roughly 1200x360 pixels and treat everything outside it as decoration.
Contrast matters more than layout on this placement. Headers sit behind an interface that switches between light and dark themes, so a light gray logo on a white background disappears for half your audience. Export a PNG if the header contains sharp text or a logo, a JPG if it is a full-bleed photograph - both are accepted, but PNG avoids a second round of compression artifacts on lettering.

Frequently Asked Questions
What is the exact Twitter header size?
1500×500 pixels (roughly 3:1). Bigger files are downscaled by X, so delivering exact size keeps text crisp.
Will my header be cropped on mobile?
Mobile crops the header to a narrower band. Keep names and logos in the central third to survive both layouts.
What file format does X accept?
JPG and PNG. JPG at quality 85% is plenty for a header and loads fastest.
