What size should my X header image be?
This tool's header preset is 1500 x 500 pixels, a 3:1 frame that is wide enough to sit behind your profile photo.
Why does X sometimes compress my image after posting?
X re-encodes most uploaded images to keep the platform's bandwidth manageable, and a large, high quality source file often comes back visibly softer once X has processed it. Resizing to X's actual display dimensions first, rather than uploading a much larger original, gives X less room to recompress aggressively, since the file is already close to the size it will be shown at.
Does the header image need to work on both desktop and the X mobile app?
Yes, and X does not offer a separate safe zone overlay for its header the way YouTube and Facebook do for their banners. Keep any text or logo well within the centre of the 1500 x 500 frame, since the app's own layout can crop the edges slightly differently between platforms and screen sizes.
Frequently asked questions
What is the best size for an image in a post?
This tool's post preset is 1200 x 675 pixels, a 16:9 ratio that suits a landscape image attached to a post.
Will my profile picture get cropped to a circle?
X displays profile pictures inside a circular mask. This tool's 400 x 400 preset keeps your subject centred so the circular crop does not cut anything important.
Does this tool post directly to X?
No, it only resizes the image locally. Download it and upload it through X as usual.
Has X's recommended post image size changed recently?
It can change, and nothing on this page tracks it for you. The 1200 x 675 preset is this tool's own size, so compare it with X's help page before you rely on it, and see the Social Media Image Sizes Cheat Sheet guide for which sizes each platform's page confirmed.
Can I resize a screenshot for an X post?
Yes, drop in a screenshot the same as any other image. Screenshots often have unusual dimensions, so resizing to the 1200 x 675 post preset first avoids X cropping it unpredictably.
What happens if my header image is smaller than 1500 x 500?
X stretches a smaller image up to fit, which can make it look soft. This tool scales your source image up to the preset size using the same fit modes as every other resizer on the site.
