Resize Image for Twitter/X Header (1500×500)
Resize images for Twitter/X headers at 1500×500 pixels. Create perfect profile banners and shared image previews. Free online tool.
Twitter (now X) header images span the full width of your profile at 1500×500 pixels — a 3:1 aspect ratio that requires specific preparation. An undersized header appears pixelated and amateur; an oversized one gets cropped unpredictably. For brands, creators, and professionals building an audience on X, that first visual impression matters enormously.
Our resizer lets you upload any image and scale it to precisely 1500×500 pixels. You'll see a live preview of the crop before committing, so you can adjust the framing to keep your logo, tagline, or key visual elements front and center. The tool also handles shared post images (1600×900 recommended for maximum timeline real estate), so you can prepare your entire X visual identity in one session.
For social media managers running multiple accounts, the batch workflow is a game-changer. Prepare headers for five different profiles, resize shared content images, and optimize file sizes — all without opening a single desktop application. The tool runs entirely in your browser, so your brand assets remain private and secure.
