Exact-pixel Image Resizer

Resize Image to 1500×500 (3:1 Header)

1500×500 is the 3:1 banner X/Twitter has used for profile headers. LinkedIn covers are a different ratio — do not reuse this file there without checking.

A short, wide strip — not a post image

How X crops the header

X displays 1500×500 at upload but overlapping UI (avatar, buttons) covers the bottom-left. Keep the subject in the upper two-thirds and away from the left 400px on mobile. A face at the bottom-left will sit under your profile photo.

Not LinkedIn, not Facebook cover

LinkedIn cover images are closer to 1584×396 (4:1-ish). Facebook covers are wider and shorter depending on device. Export a dedicated file per network. 1500×500 is the X header job.

Text on headers

Tiny slogans vanish on a phone. If you need a slogan, put it in the bio. This resizer only changes pixels.

After upload, X recompresses

Even a perfect 1500×500 JPG may gain artifacts. Start from a clean graphic, export JPG, skip PNG unless you have hard-edged brand shapes.

How it works

  1. 1

    Compose for the overlap

    Leave the bottom-left empty of important art.

  2. 2

    Export 1500×500

    Pre-filled 3:1. Download JPG.

  3. 3

    Preview on mobile X

    Desktop headers hide how much the avatar covers.
