PDFConvertersOnline.comHow to resize a header for X (Twitter)
- Choose the picture you want across the top of your profile.
- 1500×500 is preselected. Drag the preview up or down to pick the band that stays.
- Resize, save the file and upload it under Edit profile on X.
The recommended size
X's help center recommends a header image of 1500×500 pixels. That is a 3:1 shape: three times as wide as it is tall. Almost no photo comes out of a camera that way, so most pictures need cropping, and it is better to decide that crop yourself than to let the upload screen guess.
What covers your header
Your profile picture overlaps the lower-left part of the header, and on phones the visible area is cropped differently than on a wide desktop screen. The header also appears narrower in some views, so the top and bottom may be trimmed as well. To be safe:
- Keep faces, logos and text inside the middle band of the picture.
- Leave the lower-left corner for plain background, because the profile photo sits there.
- Avoid important details right at the top or bottom edge.
Framing a normal photo as a 3:1 strip
A 3:2 camera photo turned into 3:1 keeps only about two-thirds of its height. Crop to fill shows the full photo with the removed parts darkened; drag up or down to choose the band. Skylines, landscapes, desk setups and group shots taken from a distance tend to work well. Close-up portraits usually don't, because a 3:1 band through a face cuts off either the forehead or the chin; step back or choose a wider photo instead. For a logo or product that must not be cut, use Fit with background and pick a color that matches your brand; the whole picture stays visible in the center.
File type and quality
A photo header is best saved as JPG at 85–90% quality: small, and sharp at 1500 px. For a header made of flat colors and lettering, choose PNG so text edges stay clean. If you designed your header at a different size, the Size tab lets you type any dimensions, and the Resize Image page handles several files at once. Other profiles to update? There are ready-made pages for a LinkedIn banner and a Facebook cover.
Checking it on both screens
Once uploaded, X shows a positioning screen where you can zoom and move the header. Because your file already matches the 3:1 shape, you can usually save it straight away. Then look at your profile on a phone and on a computer. If a face or word is tucked behind your profile photo or cut at the edge, move the crop frame here and resize once more; it only takes a few seconds.

Frequently asked questions
What size is the X (Twitter) header?
X recommends 1500×500 pixels, a 3:1 shape.
Why is part of my header hidden?
The profile picture covers the lower-left area, and phones show a differently cropped view. Keep important content in the middle.
Can I use a vertical photo?
Yes, but a 3:1 strip will keep only a small band of it. Fit with background keeps the whole photo with colored sides instead.
Is this still right after the rename from Twitter to X?
Yes. The header size recommended in X's help center is still 1500×500.
Does this site keep a copy of my header?
No. The image is resized in your browser and is never uploaded here.
Which format should my header be?
JPG for photos, PNG for flat graphics with text. Both work on X.
