How it works

  1. Drop a wide photo or banner artwork. The 3:1 ratio is very wide, so a landscape photo is a better starting point than a portrait.
  2. Fill and crop is preselected: a 3:1 frame appears on the image. Drag it up or down to choose the strip that becomes the header.
  3. Press Resize for X header and check the preview. The centre 1500×360 is always visible; the top and bottom 70 pixels can be hidden on some screens.
  4. Upload it under Edit profile. If the subject ends up too high or too low, start over and move the frame.

Frequently asked questions

What size is an X (Twitter) header?
The X (Twitter) header size is 1500 × 500 pixels (3:1), with the profile picture covering the lower left. X's recommended header size is 1500×500 pixels (3:1). It is displayed at up to 1500 pixels wide on desktop and scaled down on phones, so anything smaller is stretched and looks soft.
What is the safe area?
Different devices crop the header slightly differently, so X advises keeping important content within the middle 1500×360 pixels. Your profile picture also overlaps the bottom-left corner, so avoid placing text there.
The image looks blurry after upload.
X re-compresses headers and can reject files over 5 MB. Export as PNG for flat artwork or JPG for photos, and avoid starting from an already heavily compressed image.
Can I keep the whole picture without cropping?
Yes: choose Fit inside. The whole picture is fitted into 1500 × 500 and the rest is padded — white in a JPG, transparent in a PNG or WebP. A 4000 × 3000 photo becomes 667 × 500 in the middle, with about 417 pixels of padding each side, so cropping a wide photo usually makes a fuller header.
Is my image uploaded to Nouplo?
No. It is resized in your browser and never leaves your device. The free plan allows 3 files per run, 20 MB per file and 5 runs per day; Pro removes those limits.
