Pick the 1500x500 preset
Choose the Twitter / X header preset (or type 1500 x 500 manually) and select Crop-to-fit to fill the full 3:1 banner with no distortion. Use Fit-inside with a background fill if you want the whole image visible.

Why 1500x500 is the size that matters
X (formerly Twitter) renders profile headers at 1500x500 px, a wide 3:1 aspect ratio. Uploading the exact dimensions keeps your banner crisp and prevents X from auto-cropping or softening it. Just as important: the header is heavily masked on different screens — your avatar covers the lower-left corner, and the top and bottom edges get trimmed on mobile and desktop alike. Keep logos, text, and faces inside a safe central band rather than near the edges.
Because 3:1 is so wide, the resize mode you choose changes everything. Crop-to-fit fills the entire 1500x500 frame edge to edge by trimming the parts of your image that overflow — ideal for photos and textures where losing a little top and bottom is fine. Fit-inside instead scales the whole image to sit within the banner and pads the remaining space with a background color you pick — better for logos or artwork you can't afford to crop. For a tall portrait or square source, Crop-to-fit usually looks cleanest; for a wide landscape shot, both modes give similar results.
Frequently asked questions
What size is a Twitter / X header?
An X (Twitter) header is 1500x500 pixels — a 3:1 aspect ratio. Uploading at these exact dimensions gives the sharpest banner and avoids automatic cropping or compression.
How do I resize an image to 1500x500 for free?
Open this Twitter header resizer, drop in your image, choose the 1500x500 preset with Crop-to-fit, then export as PNG, JPG, or WebP. It's completely free, runs in your browser, and adds no watermark.
Will my image get cropped at 1500x500?
Only if you want it to. Crop-to-fit trims the overflow to fill the full 3:1 banner, while Fit-inside scales the whole image to fit and pads the edges with a background color you choose. Keep important details centered, since X also masks the corners and edges.
Is my photo uploaded to a server?
No. This X header resizer is 100% client-side — your image is processed entirely in your browser and never uploaded, so there's no account, no waiting, and nothing leaves your device.
Can I resize several Twitter headers at once?
Yes. Add multiple images, resize them all to 1500x500 in one batch, and download everything together as a single ZIP file.
