How it works
- Upload your photo
Tap Upload photo. Resize opens with X header already picked.
- Pick what stays
The photo is cropped to 3:1. Drag the box to keep the part you want.
- Save and download
Tap Save & get link, then Download, and set it as your header on X.
Why 1500 × 500
X shows the header as a 3:1 strip at the top of your profile. A photo of exactly 1500 × 500 pixels fills it without another crop.
Keep text in the middle
On some screens X cuts a little off the top and the bottom of the header, and your profile photo covers part of the bottom left.
Profile photo and posts
The same tool makes a 400 × 400 profile photo and a 1600 × 900 image for posts.
