Twitter Header Resizer
Resize any photo to fit X (Twitter)'s header dimensions perfectly — free, instant, and processed entirely in your browser.
About the Twitter Header Resizer
X (formerly Twitter) displays profile headers at 1500×500px, a wide 3:1 banner that's easy to get wrong — too much zoom crops out key details, too little leaves awkward empty space. Getting the crop right manually in a general photo editor takes trial and error.
This tool crops and resizes your photo to the exact 1500×500px header size X uses, so you can preview the fit before downloading. No account needed — just upload, adjust, and download.
