Why this size

X sizes at a glance

The 3:1 header is cropped a little on phones, so keep edges free of text. Uploading the exact size means X does not crop or re-compress your image in ways you did not choose.

The tool scales once, straight to 1500 x 500, from your original pixels, so the result stays sharp. Start from a photo at least as large as 1500 x 500: enlarging a small image cannot add detail. For a small old photo, the AI upscaler can redraw it larger first.

Tips

Tips that make a difference

Start from the original photo

Use the photo from your camera or gallery, not a screenshot or a copy forwarded in a chat. Scaling down to 1500 x 500 keeps it sharp; scaling up a small image makes it soft.

Uploads get compressed again

Most platforms, X included, re-compress images after upload. A JPG at the exact size gives them the least to change, so colors and edges stay closer to your original.
