Crop to fill
Best when you want edge-to-edge imagery and can remove some of the original. A portrait picture loses much of its top and bottom in a wide header. Move the frame to keep the part that matters.

Resize your image for a Twitter (X) header in seconds. Crop to fill or fit the whole picture, adjust the framing, and download a 1500 × 500 banner.
Open a PNG, JPG or WebP from your device, or drop it into the editor. Try the example first if you want to explore the controls.
Crop to fill the header, then drag and zoom to position your subject. Choose Fit whole image to preserve everything and add background padding instead.
Save a PNG or JPG at 1500 × 500 pixels. On X, open Edit profile and replace the header image with your download.
Best when you want edge-to-edge imagery and can remove some of the original. A portrait picture loses much of its top and bottom in a wide header. Move the frame to keep the part that matters.
Best when the entire design must stay visible, such as a logo or an illustration with text. The picture keeps its proportions. Pick a matching background color to fill the space around it.
Both modes preserve the image’s shape. The output is always 3:1, but faces and logos are never squeezed sideways to make them fit.
X recommends 1500 × 500 pixels for your profile header. This tool fixes the output to those dimensions so you can focus on composition. The same file works as an X banner; the platform names describe the same header image.
The display can still crop the image on different screens. Keep important details away from the outer edges and the lower-left profile-photo area, then check the uploaded result on desktop and mobile. For the full crop explanation and editable templates, see our Twitter banner size guide.
Choose an image that supports what your profile says: your work, your subject, or your brand. Avoid relying on tiny text in the banner to explain everything. Write a clear introduction with the Twitter bio generator, then check both pieces together on your profile.
